1 Introduction

Over the years nature is continually surprising with diver-sified natural compounds that can be promising sources forthe discovery of new drugs important in medicine [1] Infact approximately half of the currently available drugs wereobtained from natural compounds or related [2] The use ofnatural products as an essential route to new pharmaceuticalleads is continually growing and is a research field of enor-mous interest because the different structural range of naturalcompounds can provide lead compounds for therapeuticimprovement based on rationalized molecular modifications[3 4] It is well known that scientists have curiosity in herbsand other natural plant products for research however onlyin the last years the interest in modified plant productsby animals which normally have been largely ignored andwasted has been increased [5 6]

Propolis a complex mixture of compounds also calledbee glue is a natural resinous product that honeybees collectfrom several plants and mix it with beeswax and salivaryenzymes (120573-glucosidase) [7ndash11] As inferred for the meaningof the Greek word propolismdashpro- for or in defence andpolis the city [10]mdashbees use propolis on their hives asprotection against predators and microorganisms to repairdamage as a thermal isolator and to build aseptic localsto prevent microbial infection of larvae [7 9 10 12] Sinceancient times propolis has been used by humans to meetthe needs of health and food preservation [5] but only inthe last years the interest in this complex natural producthas increased due to its broad spectrum of biological andpharmacological properties [12ndash14] Propolis is a lipophilicmaterial that is hard and breakable when cold but softflexible and very sticky when warm it possesses an enjoyablearomatic smell and different coloration including brown

green and red among others [5 7 12] In terms of chemicalcomposition it is generally composed of 50 resin 30wax 10 essential oils 5 pollen and 5 other substanceswhich includeminerals and organic compounds like phenolicacids (cinnamic and caffeic acid) or their esters flavonoids(flavones flavanones flavonols and dihydroflavonols chal-cones) terpenes aromatic aldehydes and alcohols fatty acidsstilbenes and 120573-steroids [8 9] Analysis of different samplesrevealed that propolis chemical composition is difficult tostandardize because it depends on different phytogeographiccharacteristics like vegetation season and environmentalconditions of the site of collection as bees select differentplants in different habitats for propolis production [6 8 9]

Several in vitro and in vivo studies have been describingthe plethora of biological activities and chemical profilesof propolis from different geographic origins This reviewhighlights published data about such works focusing on theantimicrobial anti-inflammatory antioxidant immunomod-ulatory and antitumor activities of different propolis types inorder to unravel the potential of this natural compound forthe development of new drugs

2 Use of Propolis in Ancientand Current Times

Propolis is not a new discovery Since beersquos domesticationmen explore its products to their own benefit and propolisone of the most important chemical weapons of bees is noexception having been employed extensively since almostimmemorial times [6 13 15ndash17] It is stated that propolis usedates back to ancient times at least to 300 BC where it wasused in folk medicine and other activities in many parts ofthe world [16] It was familiar to the Egyptians in particularby the priests who controlled medicine and chemistry andknew very well propolis antiputrefactive properties Theylearned from the bees the embalming capacity of propolis asthis natural product is used to perform the mummificationof corpses and prevent spread of infections The Greekand the Roman physicians also acknowledged the potentialof propolis by employing it in wound treatment as anantiseptic and cicatrizing agent and as mouth disinfectantThe Persians described propolis as a drug capable of actingagainst eczemas myalgia and rheumatism Populations ofthe new world like Incas also used propolis as an antipyreticagent

Between the 17th and 20th century this natural productbecame very popular in Europe In 1969 in the former Unionof Soviet Socialist Republics (USSR) the use of propolis wasaccepted in human and veterinary medicine with severalapplications including the treatment of tuberculosis wherethe regression of lung problems and recovery of appetitewere observed Also it was believed to cure some diseases infolk Georgian medicine During World War II (1939ndash1945)doctors used propolis to treat wounds [15ndash17] but only in1985 in Japan propolis was considered as very promising inpharmacology Before that propolis was considered a prod-uct without market value especially because its productionis low and affects honey production Nowadays propolisis an important product in alternative medicine in Japan

being widely imported from Brazil [18] In the 17th centurythe Italian Antonio Stradivari who is considered the mostsignificant and the greatest crafter of string instruments likeviolins used propolis as an ingredient in the varnish of hisinstruments Curiously such as in the 17th century propolisis currently used in rosin for stringed instruments and in therepair of accordions [16]

Propolis is one of the few natural products that main-tained popularity for a long time although it is not considereda therapeutic agent in conventional medicine Actually it iswidely used as a component in pharmaceutical and cosmeticproducts such as antiacne creams facial and body creamsointments and lotions and several formulations for oralhygiene [15 16] It is also used in some foods and beveragesor simply as food supplement or healthy drinks This namewas attributed to the drinks because it is thought that propolisimproves human health and prevents diseases such as heartdisease or diabetes among others [19]

3 Origin and Composition of Propolis

Propolis knowledge has registered an important evolutionover time due to exhaustive studies regarding its chem-ical composition and biological activities In the 60s itwas thought that despite its complexity propolis chemicalcomposition was more or less constant Nevertheless inthe following years analysis of a large number of samplesfrom different geographic origins revealed that chemicalcomposition of propolis is highly variable and also difficultto standardize because it depends on factors such as thevegetation season and environmental conditions of the siteof collection [6 8 9] Marcucci [7] and Bankova et al [10]registered more than 300 substances in propolis and recentreports showed the presence of compounds never mentionedbefore [12 17 20 21]

Generally the main constituents of propolis are resin andvolatiles which are substances obtained from a variety ofbotanical processes in different parts of plants and beeswaxsecreted by the bees [9] Typical compounds are summarizedin Table 1 As can be seen plant sources vary among thedifferent parts of the globe leading to panoply of compoundsIn a review on propolis standardization different resin typeswere proposed poplar propolis birch green red ldquoPacificrdquoand ldquoCanarianrdquo [9 12] Samples of poplar propolis (egfrom Europe North America New Zealand and temperatezones of Asia) are mainly composed of flavonoids phenolicacids and their esters [10 20 22] clearly different fromother propolis types (Table 1) Portuguese propolis despitesimilar to the ones found in European samples also containsnew methylated esterified and hydroxylated derivatives offlavonoids and pinocembrinpinobanksin derivatives con-taining a phenylpropanoic acid derivative moiety in theirstructure [20 21] Our group recently showed that propolisfrom Pereiro (district of Guarda Beira Alta) (Figure 1) has ahigh concentration of phenolic components [23]

Poplar-type propolis is undoubtedly themost studied onebut there are many other propolis types Recent studies haverevealed a new type of European propolis Mediterraneanpropolis This type of propolis is distinguished by the high

concentration of diterpenoids and is found in many regionslike Greece [24 25] Switzerland [26]Malta [27] Turkey [28ndash30] or Algeria [28 31]

Propolis from tropic regions like Brazil CubaVenezuelaand Chile has been attracting much attention in thelast years due to its particular chemical profiles Preny-lated phenylpropanoids prenylated p-coumaric acids ace-tophenones diterpenic acids and caffeoylquinic acids wereshown to be very common and abundant in propolis fromBrazil mainly from the south-eastern region [9 10 21]The flavonoids kaempferide and isosakuranetin and someamounts of kaempferol were also found in Brazilian samples[32] Additionally red propolis from the northeast regionsof Brazil presents high concentrations of phenolic acids andthe flavonoids formononetin isoliquiritigenin liquiritigeninmedicarpin and biochanin A [33ndash35] Cuban propolis hasa peculiar enrichment in polyisoprenylated benzophenonesmore specifically nemorosone and a minor content of amixture of xanthochymol and guttiferone E [9 36] makingthis type of sample chemically distinct from both Europeanand Brazilian propolis Propolis from Venezuela is alsocomposed of polyisoprenylated benzophenones in additionto the usual constituents found in samples of tropical regions[9 37 38]

Information about the chemical composition of Aus-tralian propolis is very limited despite the great biodiversityof the island Propolis from Kangaroo Island is mainlycomposed of stilbenes some of them being prenylated Ad-ditionally it has also some prenylated cinnamic acids andflavonoids [39] like 210158403101584041015840-trimethoxychalcone 21015840-hy-droxy-3101584041015840-dimethoxychalcone 2101584041015840-dihydroxy-31015840-metho-xychalcone 57-dihydroxy-23-dihydroflavonol 3-acetate (pi-nobanksin 3-acetate) and 57-dihydroxy-6-methoxy-23-dihydroflavonol 3-acetate [40] Western Australian propolisis composed of Xanthorrhoeol pterostilbene sakuranetinand pinostrobin [41] Propolis of Australian stingless bees(Tetragonula carbonaria) is composed of C-methylatedflavanones [42]

ldquoPacificrdquo propolis (eg Okinawa Taiwan Hawaii Indo-nesia and Myanmar) is another particular type of propolisA new family of compounds the prenylflavonoids morespecifically isonymphaeol-B was identified in Okinawapropolis although three already known compoundsmdashnym-phaeol-A nymphaeol-B and nymphaeol-Cmdashhave also

been isolated in three samples [43] As Okinawan propolisHawaiian propolis is also composed of nine prenylflavonoids[44] Taiwanese propolis is composed of eight prenylfla-vanones nymphaeol-A nymphaeol-B and nymphaeol-Cpropolins A B and E isonymphaeol B and 31015840-geranyl-naringenin [45] In another sample of the Pacific regionthe Indonesian propolis an inseparable mixture of fouralk(en)ylresorcinols (5-pentadecylresorcinol 5-(81015840Z111015840Z-heptadecadienyl)-resorcinol 5-(111015840Z-heptadecenyl)-resor-cinol and 5-heptadecylresorcinol) along with four prenylfla-vanones propolins D C F and G and three cycloartane-type triterpenes mangiferolic acid isomangiferolic acidand 27-hydroxyisomangiferolic acid was identified [46]Additionally fractioning of propolis extracts from Myanmarled to the isolation of two new cycloartane-type triterpenestogether with 13 cycloartanes and four known prenylatedflavanones [47] Thailand propolis which might bepossibly obtained from Styrax trees comprises not onlythe typical compounds of temperate regions but also thetwo new phenylallylflavanones (710158401015840S)-8-[1-(41015840-hydroxy-31015840-methoxyphenyl)prop-2-en-1-yl]-(2S)-pinocembrin and (E)-cinnamyl-(E)-cinnamylidenate [48] In propolis fromCanaryIslands a different phenolic profile was found furofuranlignans being the main compounds Six furofuran lignanswere isolated and characterized as sesamin episesaminmethyl xanthoxylol aschantin sesartenin and yangambinPropolis also contains sugars and sugar alcohols [10 49]Many studies with African propolis from different regionslike Kenya Cameroon Congo Oman and Ethiopia showedthat triterpenoids are major chemical components [50ndash53]Southern Nigeria propolis is uncommon since it presentsprenylated isoflavonoids like Brazilian red propolis and ahigh abundance of stilbenoid compounds [54]

Propolis additionally contains minerals such as mag-nesium calcium iodine potassium sodium copper zincmanganese and iron some vitamins like B1 B2 B6 CE and D as well as provitamin A a few fatty acids andalso some enzymes derived from bee glandular secretion orpossibly from pollen like succinic dehydrogenase adenosinetriphosphatase glucose-6-phosphatase acid phosphatase120572-amylase 120573-amylase 120572-lactamase 120573-lactamase maltaseesterase and transhydrogenase [17 55] Polysaccharides likestarch and the di- and monosaccharaides glucose fructoseribose rhamnose talose gulose and saccharose are com-monly present in propolis too [55]

4 Biological Properties and TherapeuticActivity of Propolis

Despite propolis popularity over time it is not consid-ered as a therapeutic agent in conventional medicine asthe standardization of chemical composition and biologicalactivity is lacking Such standardization is indispensablefor acceptance in the health system Thus characterizationof different types of propolis according to its plant originand corresponding chemical profile is mandatory Studiesabout propolis bioactivity must start with chemical profilingof the extracts since that information is essential to havedetailed and consistent comparative data between each type

of biological activity and chemical data This informationallows extrapolating the possible activity and mechanism ofaction of new propolis under study and provides substantialclues for the development of new drug candidates [6 9]

In the last decades several studies have demonstrated thebiological and pharmacological actions of different world-wide propolis samplesThe following sections summarize therecent published information about antibacterial and anti-fungal [6 7 56ndash59] antiviral [7 59 60] anti-inflammatory[61] antioxidant [62ndash64] immunomodulatory [6 65 66]and antitumor activities [8 17 23 64 66 67] revealing theinterest of researchers in this bee product and its potentialfor the development of new drugs as well

41 Antioxidant Activity It is well known that an endogenousstimuli like cellular metabolism and exogenous agents likeUV toxins and drugs among others generate reactiveoxygen species (ROS) such as hydrogen peroxide (H

2O2) the

superoxide anion (O2minus) and hydroxyl ion (HOminus) as well as

reactive nitrogen species (RNS) especially nitric oxide (NO)Carbohydrates proteins lipids and nucleic acids amongother biomolecules when exposed to the reactive speciessuffer oxidative modifications that modify the cell and leadto its death [68ndash70] Oxidative stress is responsible for theoccurrence of a wide variety of human diseases such asneurodegenerative [71] or cardiovascular diseases [72 73]cancer [68 74] diabetes [6] and atherosclerosis [75]

In the last years several studies have been performedto evaluate the antioxidant capacity of natural productsPropolis extracts composed of different polyphenols havebeen reported to possess a potent antioxidant activity [7076 77] Additionally the chemical varieties in differentpropolis samples from different regions have an influenceon the antioxidant activity Recently Fabris et al showedthat a sample of Italian and Russian propolis ethanol extract(PEE) which have a similar polyphenolic composition havea similar antioxidant activity while Brazilian PEE whichhave low polyphenolic composition have a weak antioxidantactivity [78] Another study also showed using differentsamples of Transylvania PEE a positive correlation betweenhigh polyphenolic composition and high antioxidant activity[79] Phenolic acids and flavonoids are characterized bya powerful antioxidant activity which is closely related tothe chemical structure of the compounds [80] Briefly theantioxidant activity is exerted by inhibiting the activity ofsome enzymes (eg xanthine oxidase protein kinase Cascorbic acid oxidase cyclooxygenase lipoxygenase Na+K+ATPase and cAMP phosphodiesterase) which inhibit theproduction of ROS species by scavenging interrupting thereactions that lead to the lipid peroxidation by chelatingmetal ions mainly iron and copper that are involved in theprocess of free radical creation or by potentiating the actionof other antioxidants [55] Table 2 summarizes some of thestudies addressing the antioxidant activity of propolis

Moreira et al [62] and Miguel et al [63] proposed thatPortuguese propolis an important source of total phenolsflavones and flavonols could be beneficial for human healthdue to its antioxidant properties Portuguese propolis alsoprotects human erythrocytes from free radicals damaging

by decreasing lipid peroxidation [64] These studies suggestthat Portuguese propolis is a powerful antioxidant agentthat can be used against oxidative stress thus maintainingthe structural and functional integrity of the cells Cuesta-Rubio et al [36] demonstrated that nemorosone the mostabundant polyisoprenylated benzophenone present in Cubanpropolis exhibits antioxidant capacity However when thiscompound suffers methylation a process that facilitates theseparation of the compound from the propolis sample theantioxidant property is abolished Ethyl acetate extract ofKangaroo Island propolis which is rich in stilbenes showeda stronger scavenging activity [39] Yang et al showed thatethyl acetate of propolis collected in Anhui China hasstrong scavenging activity and ferric reducing activity thoseactivities being influenced by caffeic acid phenethyl caffeatecinnamyl caffeate and benzyl caffeate [81] Another studyshowed that samples of methanolic extracts of Algerianpropolis that contains high amounts of caffeic acid estersand flavanones kaempferol and galangin possess strongscavenging activity and ferric reducing activity [31] Uruguaypropolis with high polyphenolic composition inhibits low-density lipoprotein (LDL) peroxidation and protein nitra-tion in vitro Moreover it induces the expression of nitricoxide synthase (eNOS) and inhibits NADPH oxidase inbovine aortic endothelial cells [82] In another study thetopical administration of Romanian PEE in mouse eitherprior to or after UVB exposure significantly attenuated themalondialdehyde (MDA) formation and restored glutathioneperoxidase (GSH-Px) activity [83] Talas et al [84] showedthat Turkish PEE has antioxidant properties in the livertissue of NOS inhibited rats In fact NOS inhibition causedan increase in CAT activity and MDA levels effect thatwas significantly decreased when the rats were treated withPEE It is well known that propolis composition is variablenevertheless one of itsmajor components CAPE (caffeic acidphenethyl ester) plays an important role in the antioxidantactivity [85ndash87]

Antioxidant activity is one of the most studied andimportant activities of propolis though there are no studieswith data on the safe dose to be used in humansThus clinicalstudies using propolis and its active compounds are needed

42 Anti-Inflammatory Activity Inflammation is an eventthat normally occurs in response to the constant exposureto environmental and endogenous stimuli as well as toaccidental damage [61] A complex cascade of chemicalsignals initiates after tissue injury and maintains a hostresponse to repair the injured tissue There are two stagesof inflammation acute and chronic Acute inflammation ismediated through the activation of the immune system cellswhich migrate to the site of damage and release growthfactors cytokines and ROSRNS species Chronic inflamma-tion occurs when the acute inflammation is not successfullyresolved This inflammatory condition plays a critical role inthe pathogenesis of many diseases including atherosclerosiscancer asthma Alzheimerrsquos and Parkinsonism [88 89]

Several studies have associated different types of propolisand its various constituents with anti-inflammatory activ-ity [61 90ndash95] Table 3 summarizes the anti-inflammatory

8 Evidence-Based Complementary and Alternative Medicine

mechanisms investigated with propolis and its chemicalconstituents Recently the role of the flavonoids quercetinflavonols and flavones in modulating inflammatory cellfunction was studied [92] Funakoshi-Tago et al [96] inves-tigated the anti-inflammatory effects of flavonoids isolatedfrom Nepalese PEE on the IL-33 signaling pathway Theisolated flavonoids 3101584041015840-dihydroxy-4-methoxydalbergione4-methoxydalbergion cearoin and chrysin inhibited theexpression of inflammatory genes including IL-6 TNF-120572and IL-13 in bone marrow-derived mast cells (BMMC) andalso inhibited the activation of IKK which leads to thedegradation of I120581B120572 and inhibits the activation of nuclearfactor 120581B (NF-120581B)

The release and oxygenation of arachidonic acid are acritical event in inflammation Mirzoeva and Calder [90]demonstrated that propolis components such as CAPE caf-feic acid quercetin andnaringenin among others inhibit theproduction of eicosanoids In fact these components signif-icantly suppressed the lipoxygenase pathway of arachidonicacid metabolism CAPE being the most potent modulatorAnother study indicated that CAPE treatment improveshepatic steatosis induced by high-fat diet in a mouse modelThis effect was attributed to the reduction of c-Jun-N-terminal kinase (JNK12) andNF-120581B activationwith decreasein COX-2 expression [97] Recently it was reported thatCAPE exhibits inhibitory effects on the production of proin-flammatory cytokines (interleukin-1120573 (IL-1120573)) tumor necro-sis factor-120572 (TNF-120572) and monocyte chemoattractant pro-tein 1 (MCP-1) from lipopolysaccharide- (LPS-) stimulatedRAW2647 macrophages [98] Machado et al [99] showedthat Brazilian green propolis water extracts (PWE) modulatean anti-inflammatory cellular response in the model of LPS-induced pulmonary inflammation by decreasing the numberof macrophages and neutrophils Additionally it induced areduction in the secretion of IL-6 and TNF-120572 and an increasein TGF-120573 and IL-10 Another study showed that Brazilianred PEE promotes a significant decrease in renal macrophageinfiltration in rats with chronic kidney disease [100] Bufaloet al [101] demonstrated that Brazilian PEE and caffeicacid inhibited LPS-induced NO production by RAW2647macrophages acting at the transcriptional level and sug-gesting that their anti-inflammatory effects were mediatedby downregulating NF-120581B p38 MAP kinase and JNK12According to Naito et al [95] topical application of BrazilianPEE is effective in inhibiting carrageenan-induced rat hindpaw edemaThis sample appears to inhibit the chemotaxis ofhuman polymorphonuclear leukocytes (PMNs) which alsocontributes to its anti-inflammatory effects Another studyshowed the topical anti-inflammatory activity of propolisfrom Chile in mice ear with induced-edema In fact PEEfrom Buin Chile was the most active against the inflamma-tion induced by 12-O-tetradeca-noylphorbol-13-acetate andarachidonic acid and also inhibits significantly NO releaseby the macrophages [102] More recently Boudreau et al[103] indicated that CAPE is a potent leukotriene biosynthesisinhibitor in PMNs that blocks 5-lipoxygenase (5-LO) activityand arachidonic acid release A Croatian PEE may improvepsoriatic-like skin lesions whichwere induced in the study byirritant agents like n-hexyl salicylate or di-n-propyl disulfide

by reducing the lipid peroxidation in the skin and totalnumber of inflammatory cells in the skin and peritonealcavity more specially by suppressing functional activity ofmacrophages [104]

43 Immunomodulatory Activity Natural substances areconsidered alternative adjuvant therapies in the treatment ofdifferent diseases due to their immunomodulatory effectsInformation about this type of activity was scarce for propolisuntil the 1990s but published work in the last years has pro-vided information about the influence of different propolissamples on the immune system [65 105ndash112] (Table 4)

In a study using Brazilian green propolis it was seenthat the administration for 3 days of a PEE to male BALBcmice modulated the activation of the initial steps of theimmune response by upregulating toll-like receptor- (TLR-)2 and toll-like receptor-4 expression and proinflammatorycytokines (IL-1 and IL-6) production by macrophages andspleen cells [105] Another study demonstrated that BraziliangreenPEEupregulates TLR-4 andCD80 expression in humanmonocytes as well as TNF-120572 and IL-10 production [113] Itwas also shown that caffeic acid stimulates the activity ofmonocytes againstC albicans but it inhibits TLR-2 andHLA-DR expression as well as TNF-120572 and IL-10 production [114]

Additionally Missima et al [115] showed that Braziliangreen PEE administered to stressed mice reduces the proin-flammatory cytokines IL-1120573 and IL-6 When administered tomelanoma-bearing mice submitted or not to chronic stressit induces high levels of IL-1120573 and IL-6 and also stimu-lates Th1 cytokines production indicating the activation ofantitumour cell-mediated immunity Bachiega et al [116]investigated the immunomodulatory effect of propolis andcinnamic and coumaric acids on cytokines IL-1120573 IL-6 andIL-10 production Peritonealmacrophages fromBALBcmicewere incubated with different concentrations of propolis(5 50 and 100mgwell) and coumaric and cinnamic acid(50 and 100mgwell) Propolis and the acids stimulated IL-1120573 production and significantly inhibited IL-6 productionThen after LPS incubation the inhibitory concentrations ofcinnamic and coumaric acids prevented efficiently its effectson IL-6 production whereas propolis inhibited LPS effectsboth before and after its addition Additionally propolis andcoumaric and cinnamic acids inhibited IL-10 production Astudy which evaluated the effect of Brazilian green propolison macrophage activation by H

2O2and NO metabolite

determination [107] showed that propolis increased H2O2

generation and decreased NO generation which favoursthe microbicidal activity Recently the immunomodulatoryeffect of propolis collected in Brazil was evaluated in Leish-mania (Viannia) braziliensis experimental infection Datashows that macrophages incubated with propolis showed asignificant increase in interiorization and further killing ofparasites Also an increased TNF-120572 production was seen inpropolis-pretreated mice whereas IL-12 was downregulatedduring the infection [117]

The immunomodulatory action of propolis does notoccur only at the macrophage level In fact some studiesshow that this action has also an effect on lymphocyte pro-liferation [106 108] Sa-Nunes et al [108] showed inhibitory

10 Evidence-Based Complementary and Alternative Medicine

effects of Brazilian green propolis on splenocyte proliferationeffect that was attributed to flavonoids and enhancementeffects on interferon- (IFN-) 120574 production by spleen cellsCAPE displays inhibitory effects on transcription factors NF-120581B and NFAT and as a consequence inhibits IL-2 genetranscription IL-2 receptor expression and proliferation ofhuman T cells [94] This provides new information into themolecular mechanisms involved in the anti-inflammatoryand immunomodulatory activities of propolis CAPE hasvarious biological activities but its effect on the immunomod-ulatory activity remains little studied According to Wanget al [112] CAPE can be useful in the treatment of asthmaand other allergic diseases because it can inhibit cytokinesand chemokines production by human monocyte-deriveddendritic cells (MoDCs) which might be related to theNF-120581B signalling pathway Another study demonstrated forthe first time that Brazilian propolis significantly inhibitedthe generation of Th1 cells Furthermore the effects ofpropolis were investigated on 246-trinitrobenzene sulfonicacid- (TNBS-) induced colitis in a mouse model Propolisreduced the frequency of IFN-120574-producing CD4 T cellsin a dose-dependent way under Th1-polarizing conditionsThe inhibitory effect of propolis on Th1 differentiation wasdemonstrated in vivo too and the severity of colitis inpropolis-fed mice was significantly lower than that of micefed with the control diet [118]

44 Antiviral Activity Propolis comprises a complexity ofcompounds which play a role in antiviral protection Despitethe few data available regarding this activity it was shown thatpropolis from different geographic regions has considerableantiviral activity by acting at different levels and interferingwith the replication of some viruses [12] like herpes simplextypes 1 and 2 adenovirus type 2 influenza virus or humanimmunodeficiency virus (HIV) among others [7 60 119ndash124] Table 5 summarizes the antiviral activity of propolis andits chemical constituents

Schnitzler et al [123] analysed the antiviral effect ofPWE and PEE from Czech Republic as well as that ofthe constituents caffeic acid p-coumaric acid benzoic acidgalangin pinocembrin and chrysin against herpes simplexvirus type 1 (HSV-1) in cell culture Both extracts exhibitedhigh anti-HSV-1 activity when cells were treated prior toviral infection galangin and chrysin being the main bioac-tive compounds Amoros et al [60] showed the antiviralactivity of the major flavonoids of propolis more specificallyflavonols and flavones the first being more active againstHSV-1 Additionally they analysed the effect of propolis onseveral DNA and RNA viruses (HSV-1 HSV-2 adenovirustype 2 vesicular stomatitis virus (VSV) and poliovirus type2) Propolis at a concentration of 30120583gmL reduced thetiter of herpes virus however vesicular stomatitis virusand adenovirus were less susceptible In addition propo-lis appears to exert a virucidal action on the envelopedviruses HSV and VSV [120] Recently it was shown thathydromethanolic extract of geopropolis from the stinglessbee Scaptotrigona postica (Brazil) inhibits theHSV replicationand also the entry of the virus into cells effect that wasattributed to the C-glycosyl flavones catechin-3-O-gallate

and 34-dicaffeoylquinic acid [125] According to Tait etal [126] natural and synthetic flavonoids might interferewith picornavirus replication preventing the decapsidationof viral particles and RNA release within cells or blockingviral RNA synthesis These authors also showed that differ-ent homoisoflavonoids have good antiviral activity againstthe coxsackie viruses B3 B4 and A9 and echovirus 30Shvarzbeyn and Huleihel [127] tried to determine whichstep of Tax oncoprotein-induced NF-120581B activation is blockedby propolis and CAPE and showed that both substantiallyinhibited the activation of NF-120581B-dependent promoter byTax Also they strongly prevented both Tax binding to I120581B120572and its induced degradation by Tax Ma et al [128] showedthat nanometer propolis flavones could significantly inhibitin vitro porcine parvovirus (PPV) infecting PK-15 cells andin vivo they restrain the PPV copy in lung gonad and blooddecrease the impact of PPV on weight of guinea pigs andincrease hemagglutination inhibition of PPV in serum as wellas improving the contents of IL-2 IL-6 and 120574-IFN

Over recent years therapeutic benefits of propolis andorits isolated compounds have been described in HIV treat-ment Ito et al [129] tested the anti-HIV activity in H9lymphocytes of triterpenoids melliferone moronic acidanwuweizonic acid and betulonic acid and four knownaromatic compounds isolated from Brazilian propolis andshowed that moronic acid had significant anti-HIV activityGekker et al [119] assessed the anti-HIV-1 activity of propolisin CD4+ lymphocytes and microglial cell cultures observ-ing the inhibition of viral expression in a concentration-dependent wayThe possible mechanism of propolis antiviralproperty was suggested to involve inhibition of viral entry

45 Antimicrobial Activity Antimicrobial activity one ofthe most studied propolis biological properties is very welldocumented This bioactivity has been largely investigatedin the last years due to the need of new treatments againstinfectious diseases especially with the increase of resistantpathogens to current antibiotics Tables 6 and 7 summarisethe antibacterial and antifungal activities found in propolisfrom different geographic origin andor its chemical con-stituents

451 Antibacterial Activity Propolis effect against severalbacterial strains has evaluated [7 56ndash59 130] and supportedthe fact that propolis is more active against Gram-positivebacteria than Gram-negative bacteria [12 59] Briefly datafrom different studies showed that propolis inhibits bac-terial motility and enzyme activity exhibits bacteriostaticactivity against different bacterial genera can be bactericidalin high concentrations and affects cytoplasmic membrane[130]

Mirzoeva et al [130] investigated the effect of PEEon the physiology of Bacillus subtilis Escherichia coli andRhodobacter sphaeroides proposing that propolis and someof its components like cinnamic acid and flavonoids affectthe ion permeability of the inner bacterial membrane causingthe dissipation of the membrane potential and inhibitingbacterial motility A recent study [131] provided valuableinformation for understanding the potential anti-H pylori

mechanism of CAPE H pylori a major factor for gas-trointestinal illnesses contains the enzyme H pylori peptidedeformylase that catalyses the removal of formyl group fromthe N-terminus of nascent polypeptide chains Since theaction of this enzyme is essential for H pylori survival it isconsidered a promising therapeutic drug target Results fromabsorption spectra and crystal structural characterizationshowed that CAPE is a competitive inhibitor of peptidedeformylase blocking the substrate entrance and preventingsubstrate from approaching the active site [131]

It has been suggested that the combination of propoliswith other antibiotics would allow dose reduction of selectedantibiotics thus potentiating their effect The antibacterialactivity of Italian PEE in some clinically isolated Gram-positive strains as well as the synergetic effect with someantibiotics was assessed by Scazzocchio et al [56] Ital-ian PEE drastically increased the effect of ampicillin gen-tamycin and streptomycin and moderated the action ofchloramphenicol ceftriaxone and vancomycin No effectwas observed when used simultaneously with erythromycinWojtyczka et al [132] evaluated the in vitro antimicrobialactivity of a Polish PEE against methicillin-sensitive S aureus(MSSA) and methicillin-resistant S aureus (MRSA) clinicalisolates and also the combined effect of propolis with tenselected antistaphylococcal drugs PEE displayed varyingeffectiveness against twelve S aureus strains and potentiatedthe antimicrobial effect of eight antistaphylococcal againstall tested strains No synergism was observed in the caseof ciprofloxacin and chloramphenicol In another study theeffect of dichloromethane extract of French propolis againstdifferent human pathogenic bacterial strains was also testedAlthough Gram-negative bacteria were not susceptible tothe extract a significant antibacterial activity against bothmethicillin-resistant and methicillin-susceptible S aureusstrains was observed [133] The same was confirmed byVelikova et al [28] using different PEE from BulgariaGreece Turkey and Algeria All the samples showed agood antibacterial activity against S aureus but a week orlacking effect against E coli Australian PEE from stinglessbee Tetragonula carbonaria also inhibited the growth of Saureus Nevertheless it was less active against P aeruginosa[42] The same was observed by Papachroni et al [53]using PEE from Cameroon and CongoContrary to thesestudies Katircioglu and Mercan [134] showed that TurkishPEE was effective against Gram-negative bacteria like E coliOrsi et al [135] investigated the possible synergism betweenBrazilian and Bulgarian propolis and antibiotics acting onDNA (ciprofloxacin and norfloxacin) and on metabolism(cotrimoxazole) in Salmonella typhi Both samples hadantibacterial activity but no synergistic effect was detected

Recently the suitability of nanohydroxyapatite- (nano-HA-) based surfaces containing two Brazilian PEE (greenand red ones) to prevent S aureus bacterial growth andbiofilm was studied The nanoHA impregnated with thetwo highest concentrations (12 and 25120583gmL) of red PEEshowed a remarkable reduction of 99 in the number ofviable bacteria while nanoHA with green PEE at sameconcentrations showed a reduction of 45 and 61 Moreoverthe nanoHA impregnated with the highest concentration of

red PEE was able to inhibit 80 of the staphylococcal biofilmformation [136]

Diverse studies show that as the composition of propolisvaries from region to region the antibacterial activity alsodisplays some variations [59] Susceptibility of differentGram-positive bacteria to PEE varies with the place ofpropolis collection [137] The antibacterial effect was shownto be higher for samples from a wet-tropical rain forest-type climate Other studies revealed the influence of propolisgeographical origin on its antibacterial properties [57 58 138139] Propolis from the north and centre of Portugal has agreat activity against S aureus [58 140]

452 Antifungal Activity Antifungal activity is also influ-enced by the chemical variation of propolis [59] Severalstudies have shown the effect of propolis from differentgeographic origin against different fungi particularly ofclinical interest [141ndash145] Quiroga et al [146] demonstratedthe antifungal activity of propolis from the northwest ofArgentina focusing their study on the environment andthe development of agrochemicals with reduced economiccosts possibly containing propolis extracts and its isolatedcompounds such as pinocembrin and galangin as activeprinciples

Recently Falcao et al [140] screened the antifungalactivity of Portuguese propolis and its potential floral sourcesPopulus x Canadensis and Cistus ladanifer against Candidaalbicans Trichophyton rubrum and Aspergillus fumigatusPlant extracts did not exhibit relevant antifungal activity withexception of T rubrum but both propolis samples revealedsimilar antifungal activity the highest being obtained againstT rubrum and the lowest against A fumigatus A sample ofPEE from Poland showed a high fungicidal activity againstC albicans C glabrata and C krusei [147] Recently it wasshown that different organic extracts of French propolis (PEEPWEmethanolic extract and dichloromethane extract) wereeffective against C albicans and C glabrata but only have aweak activity towards A fumigates [133]

Brazilian PEE was proved to be active against severalCandida strains (C albicans C tropicalis C krusei andC guilliermondii) C albicans being the most sensitive andC guilliermondii the most resistant [141] Brazilian greenand red propolis display activity against different fungalspecies of Trichophyton which cause dermatophytosis redPEE being more efficient than the green one [143] Also itwas shown that n-hexane extract of Brazilian red propolisdid not induce resistance in Candida spp In fact it wasactive against Candida spp resistant to antifungal agentslike fluconazole [148] Dota et al [144] evaluated the in vitroantifungal activity of PEE and propolis microparticles (PMs)obtained from a sample from Argentina against clinical yeastisolates of importance in the vulvovaginal candidiasis Calbicans and non-C albicanswere inhibited by PEE and PMswith small variation Additionally it was shown that Braziliangreen PEE has the ability to inhibit growth and biofilmformation by C albicans from vulvovaginal candidiasis [149]Another study showed fungicide action of propolis (PEEPWE propolis matricial microparticles (PMM) and propolissoluble dry extract after 6ndash8-hour treatment against all three

Evidence-Based Complementary and Alternative Medicine 17

C albicansmorphotypes (yeast pseudohyphae and hyphae)PEE being the most potent followed by PSDE PM andPWE [150] Brazilian propolis induces C albicans cell deathmediated via metacaspase since the metacaspase mutant inC albicans showed reduced sensitivity to propolis and bythe Ras pathway Using C albicans deletion libraries it waspossible to screen several mutants in genes involved eitherin the morphological transitions or in the maintenance of aspecific morphotype that are more sensitive to propolis Toconclude the study the authors also showed that propolisbased gels and cream were partially able to control vulvo-vaginal candidiasis in a mouse model [151] These studies[144] strongly indicate that propolis has a great potential tocontrol vulvovaginal candidiasis representing a promisingalternative therapeutic strategy

46 Antitumour Activity Recognition of the hallmarks ofcancer affects the search and development of new meth-ods and therapeutic agents with a sufficiently large thera-peutic window to kill tumour cells while sparing normalcells In the last years the natural product propolis hasattracted a growing interest by a large number of researcherssince it contains a variety of phytochemical compoundsthat may act through multiple pathways to reduce thedevelopment and other malignant characteristics of cancercells

Recently several in vitro studies have demonstrated acytotoxic action of propolis from different geographic originand of some of its isolated compounds on various tumourcells In vivo studies also show a potential in the developmentof new antitumor agents since propolis administration tomammals (eg rats) does not lead to detectable side effects[3] Briefly this natural product can block specific oncogenesignalling pathways which in turn lead to a decrease in cellproliferation and growth and can also act by decreasing thecancer stem cell population increasing apoptosis exertingantiangiogenic effects and modulating the tumour microen-vironment [66 152 153] Table 8 summarizes the antitumouractivity of propolis from different geographic origin and itschemical constituents

Some researchers showed the effect of different types ofpropolis and its constituents on cancer cell growth prolifera-tion and apoptosisThe hexane extract of propolis fromThai-land collected by the stingless bee Trigona laeviceps whichhas a different behavior in propolis collection compared tothe honey bees exerts antiproliferative activity against fivetested cancer cell lines (Chago KATO-III SW620 BT474and Hep-G2) but not against the normal cell lines tested(HS27 fibroblast and CH-liver) [5] A sample of PEE fromPoland inhibited human malignant melanoma (Me45) andcolorectal cancer (HCT 116) cells growth as well as reducedcell size [154]Other studies reported the antitumor activity ofBrazilianPEE [155ndash158]which regulate the protein expressionof cyclin D1 B1 and cyclin dependent kinase (CDK) as wellas p21 in human prostate cancer cells significantly affectingproliferation [158]

Although propolis containing CAPE is different fromthose with artepillin C it is possible to obtain a similarinhibitory effect from both types The effect of CAPE on

different cancer cell lines was analysed and many of itseffects have been shown to be mediated through inhibitionof NF-120581B [66 159] CAPE can inhibit the proliferation of thecolorectal cell line SW480 by decreasing the 120573-catenin c-myc and cyclin D1 protein expression [160] Chuu et al [161]observed that CAPE suppressed the proliferation of LNCaPDU-145 and PC-3 human prostate cancer cells in a dose-dependent manner and also inhibited the tumour growthof LNCaP xenografts in nude mice It was suggested that itacted through inhibition of p70S6K (an intermediary of thePI3KAKTpathway responsible for the protein synthesis) andsome Akt signalling networks Wu et al [162] demonstratedthat CAPE inhibits in vitro and in vivoMCF-7 andMDA-MB-231 tumour growthwithoutmuch effect on normalmammarycells by reducing the expression of growth and transcriptionfactors including NF-120581B Recently it was demonstrated thatCAPE effect on genes that are associated with tumour cellgrowth and survival is related in part to its role as a histonedeacetylase inhibitor [163]

As previously said propolis can also act by decreasingthe cancer stem cell population Using the putative CD44(+)CD24 (minuslow) breast cancer stem cells able to generatemammospheres from single cells Omene et al [164] showedthat CAPE caused a dose-dependent inhibition of cancerstem cells self-renewal progenitor formation and clonalgrowth

Concerning cell death some in vitro studies showeddifferent sensitivities of tumour cells to propolis extractsPWE from Iraq inhibits the proliferation of HL-60 cellsand leads to downregulation of Bcl-2 and activation of Bax[13] Alizadeh et al [165] investigated the protective effectsof Iranian PEE on N-methyl-N-nitro-N-nitrosoguanidine-(MNNG-) initiated gastric cancer in rats Results showedthat tumour incidence the number of lesions structuralabnormalities and beta-catenin of the animals group treatedwith PEE significantly declined compared with the controlPEE also induced the expression of proapoptotic Bax andreduced antiapoptotic Bcl-2 expression Propolis inhibitscolony formation potential and promotes necrotic changes inHCT-116 cells and decreases mitotic cells and increases p53and Ki-67 expression in HCT-116 tumor-bearing mice [13]Szliszkarsquos group have performed many studies to analyze theantitumour effect of different propolis and its constituentson prostate cancer cells (LNCaP and DU145) [166ndash168]Brazilian green PEE sensitized these cells to TRAIL-induceddeath enhanced the expression of TRAIL-R2 and decreasedthe activity of NF-120581B in LNCaP cells [167] Cotreatment ofTRAIL with artepillin C induced the significant activation ofcaspase-8 and caspase-3 as well as a significant disruption ofthe mitochondrial membrane potential [169] Many studieshave been conducted to understand the pathways involvedin the apoptotic effect of CAPE CAPE induces cell cyclearrest and apoptosis and reduces expression of NF-120581B inMDA-MB-231 and MCF-7 human breast cancer cells [162]In PC3 prostate cancer cells CAPE induced apoptosis in adose-dependent manner that was associated with the loss ofexpression of the inhibitors of apoptosis cIAP-1 cIAP-2 andXIAP [170] Cavaliere et al [171] showed that CAPE treatment

of lymphoblastoid cell line PL104 induced apoptosis throughthe mitochondrial intrinsic pathway

It has been known that cancer microenvironment isvery important for carcinogenesis and it consists of stromalendothelial immune and cancer cells Natural productslike propolis and their constituents have been shown tointerfere with this symbiosis It was demonstrated by Lee et al[172] that CAPE could effectively suppress the adhesion andinvasion potential of human hepatocellular carcinoma cells(SK-Hep1) by inhibiting the expression ofMMP-2 andMMP-9 and NF-120581B

Angiogenesis has a crucial role in tumour growth dueto the requirement of oxygen and nutrients to sustain rapiduncontrolled proliferation and metastization Both tumourand stromal cells can secrete proangiogenic factors thatstimulate the formation andmaintenance of new vessels suchas vascular endothelial growth factor (VEGF) [173] BrazilianPEE could significantly reduce the number of newly formedvessels and suppress the proliferation of human umbilicalvein endothelial cells (HUVECs) [174] this antiangiogeniceffect being mainly mediated via inducing apoptosis in tube-forming endothelial cells through the inactivation of the sur-vival signal ERK12 [175] Yun et al [176] observed that CAPEinhibited angiogenesis using the in vivo assay chick embryochorioallantoic membrane (CAM) CAPE also suppressesVEGF formation by MDA-MB-231 cells and formation ofcapillary-like tubes by endothelial cells [162 177] Extractsof propolis containing artepillin C and CAPE significantlyreduced the newly formed vessels and expression of MMPsand VEGF production from various cells [178] and inaccordance with this study Izuta et al [179] described thatCAPE promotes inhibition of VEGF expression in HUVECcells

The first study on the antitumor activity of Portuguesepropolis was only performed in 2010 Using normal andcancerous renal cells derived from human renal cell carci-noma (RCC) patients in addition to A-498 cell line Valenteet al [64] showed that methanolic extract of Portuguesepropolis exhibited selective toxicity against malignant cellscompared to normal cells and in vitro RCC growth wasstrongly inhibited Recently our group demonstrated theantitumour and antiangiogenic activity of the ethanol extractof Pereiro propolis (P10EE) collected in the district ofGuarda Portugal P10EE affects cell viability of differenttumour cells MDA-MB-231 (breast) and DU145 (prostate)being two of the most sensitive ones but was less cytotoxicagainst nontumour cells and fibroblasts Also it signifi-cantly decreased MDA-MB-231 and DU145 cell prolifera-tion and migration along time with cell cycle changesand increased cell death The significant increase observedin glucose consumption and lactate production could beexplained in MDA-MB-231 by an increased expression ofhypoxia inducible factor-1120572 pyruvate dehydrogenase kinaseglucose transporter 1 lactate dehydrogenase and carbonicanhydrase Furthermore P10EE induced a decrease inHBMECs total biomass and proliferation and decreasedvessel sprouting in the chicken chorioallantoic membrane[23]

5 Conclusions

From ancient to modern times herbs and other plant prod-ucts have been widely used as medicinal agents first in folkmedicine and other activities in many parts of the world andlater developed and improved on a scientific basis into drugsthat are used in the health system Propolis is one of thefew natural products that has maintained its popularity overa long period of time As reviewed here propolis containsa broad spectrum of compounds that may be useful in thetreatment of different pathological conditions In fact there ismuch literature that deals with the in vitro and in vivo biologi-cal properties of propolisThis wide range of bioactivities thecontinuous discovery of new compounds the long history ofpropolis use and its safety profile make propolis a potentialcandidate for drug discovery that may be useful in severalclinical scenarios Nevertheless it is necessary to make aneffort to standardize propolis composition since it seems thatpropolis biological properties and chemical composition notonly are variable but also are strictly linked In our opinionpropolis extracts may be important economically and wouldallow a relatively inexpensive treatment in different diseaseshowever to promote its use in modern medicine it will benecessary to identify and isolate the bioactive compoundsto be tested separately or in combination with other drugsalready available

Drug discovery does not consist only of the isolationof bioactive lead compounds from the natural sources Infact this process continues outside the academic laboratoriesthrough preclinical studies followed by clinical trials Thusdespite the in vitro and in vivo assays which provide newvaluable information on propolis biological properties andmechanisms of action it will be necessary to analyse theeffectiveness of propolis clinically to complement the basicresearch available and to evaluate the potential of propolis inhuman health promotion

green and red among others [5 7 12] In terms of chemicalcomposition it is generally composed of 50 resin 30wax 10 essential oils 5 pollen and 5 other substanceswhich includeminerals and organic compounds like phenolicacids (cinnamic and caffeic acid) or their esters flavonoids(flavones flavanones flavonols and dihydroflavonols chal-cones) terpenes aromatic aldehydes and alcohols fatty acidsstilbenes and 120573-steroids [8 9] Analysis of different samplesrevealed that propolis chemical composition is difficult tostandardize because it depends on different phytogeographiccharacteristics like vegetation season and environmentalconditions of the site of collection as bees select differentplants in different habitats for propolis production [6 8 9]

Several in vitro and in vivo studies have been describingthe plethora of biological activities and chemical profilesof propolis from different geographic origins This reviewhighlights published data about such works focusing on theantimicrobial anti-inflammatory antioxidant immunomod-ulatory and antitumor activities of different propolis types inorder to unravel the potential of this natural compound forthe development of new drugs

2 Use of Propolis in Ancientand Current Times

Propolis is not a new discovery Since beersquos domesticationmen explore its products to their own benefit and propolisone of the most important chemical weapons of bees is noexception having been employed extensively since almostimmemorial times [6 13 15ndash17] It is stated that propolis usedates back to ancient times at least to 300 BC where it wasused in folk medicine and other activities in many parts ofthe world [16] It was familiar to the Egyptians in particularby the priests who controlled medicine and chemistry andknew very well propolis antiputrefactive properties Theylearned from the bees the embalming capacity of propolis asthis natural product is used to perform the mummificationof corpses and prevent spread of infections The Greekand the Roman physicians also acknowledged the potentialof propolis by employing it in wound treatment as anantiseptic and cicatrizing agent and as mouth disinfectantThe Persians described propolis as a drug capable of actingagainst eczemas myalgia and rheumatism Populations ofthe new world like Incas also used propolis as an antipyreticagent

Between the 17th and 20th century this natural productbecame very popular in Europe In 1969 in the former Unionof Soviet Socialist Republics (USSR) the use of propolis wasaccepted in human and veterinary medicine with severalapplications including the treatment of tuberculosis wherethe regression of lung problems and recovery of appetitewere observed Also it was believed to cure some diseases infolk Georgian medicine During World War II (1939ndash1945)doctors used propolis to treat wounds [15ndash17] but only in1985 in Japan propolis was considered as very promising inpharmacology Before that propolis was considered a prod-uct without market value especially because its productionis low and affects honey production Nowadays propolisis an important product in alternative medicine in Japan

being widely imported from Brazil [18] In the 17th centurythe Italian Antonio Stradivari who is considered the mostsignificant and the greatest crafter of string instruments likeviolins used propolis as an ingredient in the varnish of hisinstruments Curiously such as in the 17th century propolisis currently used in rosin for stringed instruments and in therepair of accordions [16]

Propolis is one of the few natural products that main-tained popularity for a long time although it is not considereda therapeutic agent in conventional medicine Actually it iswidely used as a component in pharmaceutical and cosmeticproducts such as antiacne creams facial and body creamsointments and lotions and several formulations for oralhygiene [15 16] It is also used in some foods and beveragesor simply as food supplement or healthy drinks This namewas attributed to the drinks because it is thought that propolisimproves human health and prevents diseases such as heartdisease or diabetes among others [19]

3 Origin and Composition of Propolis

Propolis knowledge has registered an important evolutionover time due to exhaustive studies regarding its chem-ical composition and biological activities In the 60s itwas thought that despite its complexity propolis chemicalcomposition was more or less constant Nevertheless inthe following years analysis of a large number of samplesfrom different geographic origins revealed that chemicalcomposition of propolis is highly variable and also difficultto standardize because it depends on factors such as thevegetation season and environmental conditions of the siteof collection [6 8 9] Marcucci [7] and Bankova et al [10]registered more than 300 substances in propolis and recentreports showed the presence of compounds never mentionedbefore [12 17 20 21]

Generally the main constituents of propolis are resin andvolatiles which are substances obtained from a variety ofbotanical processes in different parts of plants and beeswaxsecreted by the bees [9] Typical compounds are summarizedin Table 1 As can be seen plant sources vary among thedifferent parts of the globe leading to panoply of compoundsIn a review on propolis standardization different resin typeswere proposed poplar propolis birch green red ldquoPacificrdquoand ldquoCanarianrdquo [9 12] Samples of poplar propolis (egfrom Europe North America New Zealand and temperatezones of Asia) are mainly composed of flavonoids phenolicacids and their esters [10 20 22] clearly different fromother propolis types (Table 1) Portuguese propolis despitesimilar to the ones found in European samples also containsnew methylated esterified and hydroxylated derivatives offlavonoids and pinocembrinpinobanksin derivatives con-taining a phenylpropanoic acid derivative moiety in theirstructure [20 21] Our group recently showed that propolisfrom Pereiro (district of Guarda Beira Alta) (Figure 1) has ahigh concentration of phenolic components [23]

Poplar-type propolis is undoubtedly themost studied onebut there are many other propolis types Recent studies haverevealed a new type of European propolis Mediterraneanpropolis This type of propolis is distinguished by the high

concentration of diterpenoids and is found in many regionslike Greece [24 25] Switzerland [26]Malta [27] Turkey [28ndash30] or Algeria [28 31]

Propolis from tropic regions like Brazil CubaVenezuelaand Chile has been attracting much attention in thelast years due to its particular chemical profiles Preny-lated phenylpropanoids prenylated p-coumaric acids ace-tophenones diterpenic acids and caffeoylquinic acids wereshown to be very common and abundant in propolis fromBrazil mainly from the south-eastern region [9 10 21]The flavonoids kaempferide and isosakuranetin and someamounts of kaempferol were also found in Brazilian samples[32] Additionally red propolis from the northeast regionsof Brazil presents high concentrations of phenolic acids andthe flavonoids formononetin isoliquiritigenin liquiritigeninmedicarpin and biochanin A [33ndash35] Cuban propolis hasa peculiar enrichment in polyisoprenylated benzophenonesmore specifically nemorosone and a minor content of amixture of xanthochymol and guttiferone E [9 36] makingthis type of sample chemically distinct from both Europeanand Brazilian propolis Propolis from Venezuela is alsocomposed of polyisoprenylated benzophenones in additionto the usual constituents found in samples of tropical regions[9 37 38]

Information about the chemical composition of Aus-tralian propolis is very limited despite the great biodiversityof the island Propolis from Kangaroo Island is mainlycomposed of stilbenes some of them being prenylated Ad-ditionally it has also some prenylated cinnamic acids andflavonoids [39] like 210158403101584041015840-trimethoxychalcone 21015840-hy-droxy-3101584041015840-dimethoxychalcone 2101584041015840-dihydroxy-31015840-metho-xychalcone 57-dihydroxy-23-dihydroflavonol 3-acetate (pi-nobanksin 3-acetate) and 57-dihydroxy-6-methoxy-23-dihydroflavonol 3-acetate [40] Western Australian propolisis composed of Xanthorrhoeol pterostilbene sakuranetinand pinostrobin [41] Propolis of Australian stingless bees(Tetragonula carbonaria) is composed of C-methylatedflavanones [42]

ldquoPacificrdquo propolis (eg Okinawa Taiwan Hawaii Indo-nesia and Myanmar) is another particular type of propolisA new family of compounds the prenylflavonoids morespecifically isonymphaeol-B was identified in Okinawapropolis although three already known compoundsmdashnym-phaeol-A nymphaeol-B and nymphaeol-Cmdashhave also

been isolated in three samples [43] As Okinawan propolisHawaiian propolis is also composed of nine prenylflavonoids[44] Taiwanese propolis is composed of eight prenylfla-vanones nymphaeol-A nymphaeol-B and nymphaeol-Cpropolins A B and E isonymphaeol B and 31015840-geranyl-naringenin [45] In another sample of the Pacific regionthe Indonesian propolis an inseparable mixture of fouralk(en)ylresorcinols (5-pentadecylresorcinol 5-(81015840Z111015840Z-heptadecadienyl)-resorcinol 5-(111015840Z-heptadecenyl)-resor-cinol and 5-heptadecylresorcinol) along with four prenylfla-vanones propolins D C F and G and three cycloartane-type triterpenes mangiferolic acid isomangiferolic acidand 27-hydroxyisomangiferolic acid was identified [46]Additionally fractioning of propolis extracts from Myanmarled to the isolation of two new cycloartane-type triterpenestogether with 13 cycloartanes and four known prenylatedflavanones [47] Thailand propolis which might bepossibly obtained from Styrax trees comprises not onlythe typical compounds of temperate regions but also thetwo new phenylallylflavanones (710158401015840S)-8-[1-(41015840-hydroxy-31015840-methoxyphenyl)prop-2-en-1-yl]-(2S)-pinocembrin and (E)-cinnamyl-(E)-cinnamylidenate [48] In propolis fromCanaryIslands a different phenolic profile was found furofuranlignans being the main compounds Six furofuran lignanswere isolated and characterized as sesamin episesaminmethyl xanthoxylol aschantin sesartenin and yangambinPropolis also contains sugars and sugar alcohols [10 49]Many studies with African propolis from different regionslike Kenya Cameroon Congo Oman and Ethiopia showedthat triterpenoids are major chemical components [50ndash53]Southern Nigeria propolis is uncommon since it presentsprenylated isoflavonoids like Brazilian red propolis and ahigh abundance of stilbenoid compounds [54]

Propolis additionally contains minerals such as mag-nesium calcium iodine potassium sodium copper zincmanganese and iron some vitamins like B1 B2 B6 CE and D as well as provitamin A a few fatty acids andalso some enzymes derived from bee glandular secretion orpossibly from pollen like succinic dehydrogenase adenosinetriphosphatase glucose-6-phosphatase acid phosphatase120572-amylase 120573-amylase 120572-lactamase 120573-lactamase maltaseesterase and transhydrogenase [17 55] Polysaccharides likestarch and the di- and monosaccharaides glucose fructoseribose rhamnose talose gulose and saccharose are com-monly present in propolis too [55]

4 Biological Properties and TherapeuticActivity of Propolis

Despite propolis popularity over time it is not consid-ered as a therapeutic agent in conventional medicine asthe standardization of chemical composition and biologicalactivity is lacking Such standardization is indispensablefor acceptance in the health system Thus characterizationof different types of propolis according to its plant originand corresponding chemical profile is mandatory Studiesabout propolis bioactivity must start with chemical profilingof the extracts since that information is essential to havedetailed and consistent comparative data between each type

of biological activity and chemical data This informationallows extrapolating the possible activity and mechanism ofaction of new propolis under study and provides substantialclues for the development of new drug candidates [6 9]

In the last decades several studies have demonstrated thebiological and pharmacological actions of different world-wide propolis samplesThe following sections summarize therecent published information about antibacterial and anti-fungal [6 7 56ndash59] antiviral [7 59 60] anti-inflammatory[61] antioxidant [62ndash64] immunomodulatory [6 65 66]and antitumor activities [8 17 23 64 66 67] revealing theinterest of researchers in this bee product and its potentialfor the development of new drugs as well

41 Antioxidant Activity It is well known that an endogenousstimuli like cellular metabolism and exogenous agents likeUV toxins and drugs among others generate reactiveoxygen species (ROS) such as hydrogen peroxide (H

2O2) the

superoxide anion (O2minus) and hydroxyl ion (HOminus) as well as

reactive nitrogen species (RNS) especially nitric oxide (NO)Carbohydrates proteins lipids and nucleic acids amongother biomolecules when exposed to the reactive speciessuffer oxidative modifications that modify the cell and leadto its death [68ndash70] Oxidative stress is responsible for theoccurrence of a wide variety of human diseases such asneurodegenerative [71] or cardiovascular diseases [72 73]cancer [68 74] diabetes [6] and atherosclerosis [75]

In the last years several studies have been performedto evaluate the antioxidant capacity of natural productsPropolis extracts composed of different polyphenols havebeen reported to possess a potent antioxidant activity [7076 77] Additionally the chemical varieties in differentpropolis samples from different regions have an influenceon the antioxidant activity Recently Fabris et al showedthat a sample of Italian and Russian propolis ethanol extract(PEE) which have a similar polyphenolic composition havea similar antioxidant activity while Brazilian PEE whichhave low polyphenolic composition have a weak antioxidantactivity [78] Another study also showed using differentsamples of Transylvania PEE a positive correlation betweenhigh polyphenolic composition and high antioxidant activity[79] Phenolic acids and flavonoids are characterized bya powerful antioxidant activity which is closely related tothe chemical structure of the compounds [80] Briefly theantioxidant activity is exerted by inhibiting the activity ofsome enzymes (eg xanthine oxidase protein kinase Cascorbic acid oxidase cyclooxygenase lipoxygenase Na+K+ATPase and cAMP phosphodiesterase) which inhibit theproduction of ROS species by scavenging interrupting thereactions that lead to the lipid peroxidation by chelatingmetal ions mainly iron and copper that are involved in theprocess of free radical creation or by potentiating the actionof other antioxidants [55] Table 2 summarizes some of thestudies addressing the antioxidant activity of propolis

Moreira et al [62] and Miguel et al [63] proposed thatPortuguese propolis an important source of total phenolsflavones and flavonols could be beneficial for human healthdue to its antioxidant properties Portuguese propolis alsoprotects human erythrocytes from free radicals damaging

by decreasing lipid peroxidation [64] These studies suggestthat Portuguese propolis is a powerful antioxidant agentthat can be used against oxidative stress thus maintainingthe structural and functional integrity of the cells Cuesta-Rubio et al [36] demonstrated that nemorosone the mostabundant polyisoprenylated benzophenone present in Cubanpropolis exhibits antioxidant capacity However when thiscompound suffers methylation a process that facilitates theseparation of the compound from the propolis sample theantioxidant property is abolished Ethyl acetate extract ofKangaroo Island propolis which is rich in stilbenes showeda stronger scavenging activity [39] Yang et al showed thatethyl acetate of propolis collected in Anhui China hasstrong scavenging activity and ferric reducing activity thoseactivities being influenced by caffeic acid phenethyl caffeatecinnamyl caffeate and benzyl caffeate [81] Another studyshowed that samples of methanolic extracts of Algerianpropolis that contains high amounts of caffeic acid estersand flavanones kaempferol and galangin possess strongscavenging activity and ferric reducing activity [31] Uruguaypropolis with high polyphenolic composition inhibits low-density lipoprotein (LDL) peroxidation and protein nitra-tion in vitro Moreover it induces the expression of nitricoxide synthase (eNOS) and inhibits NADPH oxidase inbovine aortic endothelial cells [82] In another study thetopical administration of Romanian PEE in mouse eitherprior to or after UVB exposure significantly attenuated themalondialdehyde (MDA) formation and restored glutathioneperoxidase (GSH-Px) activity [83] Talas et al [84] showedthat Turkish PEE has antioxidant properties in the livertissue of NOS inhibited rats In fact NOS inhibition causedan increase in CAT activity and MDA levels effect thatwas significantly decreased when the rats were treated withPEE It is well known that propolis composition is variablenevertheless one of itsmajor components CAPE (caffeic acidphenethyl ester) plays an important role in the antioxidantactivity [85ndash87]

Antioxidant activity is one of the most studied andimportant activities of propolis though there are no studieswith data on the safe dose to be used in humansThus clinicalstudies using propolis and its active compounds are needed

42 Anti-Inflammatory Activity Inflammation is an eventthat normally occurs in response to the constant exposureto environmental and endogenous stimuli as well as toaccidental damage [61] A complex cascade of chemicalsignals initiates after tissue injury and maintains a hostresponse to repair the injured tissue There are two stagesof inflammation acute and chronic Acute inflammation ismediated through the activation of the immune system cellswhich migrate to the site of damage and release growthfactors cytokines and ROSRNS species Chronic inflamma-tion occurs when the acute inflammation is not successfullyresolved This inflammatory condition plays a critical role inthe pathogenesis of many diseases including atherosclerosiscancer asthma Alzheimerrsquos and Parkinsonism [88 89]

Several studies have associated different types of propolisand its various constituents with anti-inflammatory activ-ity [61 90ndash95] Table 3 summarizes the anti-inflammatory

8 Evidence-Based Complementary and Alternative Medicine

mechanisms investigated with propolis and its chemicalconstituents Recently the role of the flavonoids quercetinflavonols and flavones in modulating inflammatory cellfunction was studied [92] Funakoshi-Tago et al [96] inves-tigated the anti-inflammatory effects of flavonoids isolatedfrom Nepalese PEE on the IL-33 signaling pathway Theisolated flavonoids 3101584041015840-dihydroxy-4-methoxydalbergione4-methoxydalbergion cearoin and chrysin inhibited theexpression of inflammatory genes including IL-6 TNF-120572and IL-13 in bone marrow-derived mast cells (BMMC) andalso inhibited the activation of IKK which leads to thedegradation of I120581B120572 and inhibits the activation of nuclearfactor 120581B (NF-120581B)

The release and oxygenation of arachidonic acid are acritical event in inflammation Mirzoeva and Calder [90]demonstrated that propolis components such as CAPE caf-feic acid quercetin andnaringenin among others inhibit theproduction of eicosanoids In fact these components signif-icantly suppressed the lipoxygenase pathway of arachidonicacid metabolism CAPE being the most potent modulatorAnother study indicated that CAPE treatment improveshepatic steatosis induced by high-fat diet in a mouse modelThis effect was attributed to the reduction of c-Jun-N-terminal kinase (JNK12) andNF-120581B activationwith decreasein COX-2 expression [97] Recently it was reported thatCAPE exhibits inhibitory effects on the production of proin-flammatory cytokines (interleukin-1120573 (IL-1120573)) tumor necro-sis factor-120572 (TNF-120572) and monocyte chemoattractant pro-tein 1 (MCP-1) from lipopolysaccharide- (LPS-) stimulatedRAW2647 macrophages [98] Machado et al [99] showedthat Brazilian green propolis water extracts (PWE) modulatean anti-inflammatory cellular response in the model of LPS-induced pulmonary inflammation by decreasing the numberof macrophages and neutrophils Additionally it induced areduction in the secretion of IL-6 and TNF-120572 and an increasein TGF-120573 and IL-10 Another study showed that Brazilianred PEE promotes a significant decrease in renal macrophageinfiltration in rats with chronic kidney disease [100] Bufaloet al [101] demonstrated that Brazilian PEE and caffeicacid inhibited LPS-induced NO production by RAW2647macrophages acting at the transcriptional level and sug-gesting that their anti-inflammatory effects were mediatedby downregulating NF-120581B p38 MAP kinase and JNK12According to Naito et al [95] topical application of BrazilianPEE is effective in inhibiting carrageenan-induced rat hindpaw edemaThis sample appears to inhibit the chemotaxis ofhuman polymorphonuclear leukocytes (PMNs) which alsocontributes to its anti-inflammatory effects Another studyshowed the topical anti-inflammatory activity of propolisfrom Chile in mice ear with induced-edema In fact PEEfrom Buin Chile was the most active against the inflamma-tion induced by 12-O-tetradeca-noylphorbol-13-acetate andarachidonic acid and also inhibits significantly NO releaseby the macrophages [102] More recently Boudreau et al[103] indicated that CAPE is a potent leukotriene biosynthesisinhibitor in PMNs that blocks 5-lipoxygenase (5-LO) activityand arachidonic acid release A Croatian PEE may improvepsoriatic-like skin lesions whichwere induced in the study byirritant agents like n-hexyl salicylate or di-n-propyl disulfide

by reducing the lipid peroxidation in the skin and totalnumber of inflammatory cells in the skin and peritonealcavity more specially by suppressing functional activity ofmacrophages [104]

43 Immunomodulatory Activity Natural substances areconsidered alternative adjuvant therapies in the treatment ofdifferent diseases due to their immunomodulatory effectsInformation about this type of activity was scarce for propolisuntil the 1990s but published work in the last years has pro-vided information about the influence of different propolissamples on the immune system [65 105ndash112] (Table 4)

In a study using Brazilian green propolis it was seenthat the administration for 3 days of a PEE to male BALBcmice modulated the activation of the initial steps of theimmune response by upregulating toll-like receptor- (TLR-)2 and toll-like receptor-4 expression and proinflammatorycytokines (IL-1 and IL-6) production by macrophages andspleen cells [105] Another study demonstrated that BraziliangreenPEEupregulates TLR-4 andCD80 expression in humanmonocytes as well as TNF-120572 and IL-10 production [113] Itwas also shown that caffeic acid stimulates the activity ofmonocytes againstC albicans but it inhibits TLR-2 andHLA-DR expression as well as TNF-120572 and IL-10 production [114]

Additionally Missima et al [115] showed that Braziliangreen PEE administered to stressed mice reduces the proin-flammatory cytokines IL-1120573 and IL-6 When administered tomelanoma-bearing mice submitted or not to chronic stressit induces high levels of IL-1120573 and IL-6 and also stimu-lates Th1 cytokines production indicating the activation ofantitumour cell-mediated immunity Bachiega et al [116]investigated the immunomodulatory effect of propolis andcinnamic and coumaric acids on cytokines IL-1120573 IL-6 andIL-10 production Peritonealmacrophages fromBALBcmicewere incubated with different concentrations of propolis(5 50 and 100mgwell) and coumaric and cinnamic acid(50 and 100mgwell) Propolis and the acids stimulated IL-1120573 production and significantly inhibited IL-6 productionThen after LPS incubation the inhibitory concentrations ofcinnamic and coumaric acids prevented efficiently its effectson IL-6 production whereas propolis inhibited LPS effectsboth before and after its addition Additionally propolis andcoumaric and cinnamic acids inhibited IL-10 production Astudy which evaluated the effect of Brazilian green propolison macrophage activation by H

2O2and NO metabolite

determination [107] showed that propolis increased H2O2

generation and decreased NO generation which favoursthe microbicidal activity Recently the immunomodulatoryeffect of propolis collected in Brazil was evaluated in Leish-mania (Viannia) braziliensis experimental infection Datashows that macrophages incubated with propolis showed asignificant increase in interiorization and further killing ofparasites Also an increased TNF-120572 production was seen inpropolis-pretreated mice whereas IL-12 was downregulatedduring the infection [117]

The immunomodulatory action of propolis does notoccur only at the macrophage level In fact some studiesshow that this action has also an effect on lymphocyte pro-liferation [106 108] Sa-Nunes et al [108] showed inhibitory

10 Evidence-Based Complementary and Alternative Medicine

effects of Brazilian green propolis on splenocyte proliferationeffect that was attributed to flavonoids and enhancementeffects on interferon- (IFN-) 120574 production by spleen cellsCAPE displays inhibitory effects on transcription factors NF-120581B and NFAT and as a consequence inhibits IL-2 genetranscription IL-2 receptor expression and proliferation ofhuman T cells [94] This provides new information into themolecular mechanisms involved in the anti-inflammatoryand immunomodulatory activities of propolis CAPE hasvarious biological activities but its effect on the immunomod-ulatory activity remains little studied According to Wanget al [112] CAPE can be useful in the treatment of asthmaand other allergic diseases because it can inhibit cytokinesand chemokines production by human monocyte-deriveddendritic cells (MoDCs) which might be related to theNF-120581B signalling pathway Another study demonstrated forthe first time that Brazilian propolis significantly inhibitedthe generation of Th1 cells Furthermore the effects ofpropolis were investigated on 246-trinitrobenzene sulfonicacid- (TNBS-) induced colitis in a mouse model Propolisreduced the frequency of IFN-120574-producing CD4 T cellsin a dose-dependent way under Th1-polarizing conditionsThe inhibitory effect of propolis on Th1 differentiation wasdemonstrated in vivo too and the severity of colitis inpropolis-fed mice was significantly lower than that of micefed with the control diet [118]

44 Antiviral Activity Propolis comprises a complexity ofcompounds which play a role in antiviral protection Despitethe few data available regarding this activity it was shown thatpropolis from different geographic regions has considerableantiviral activity by acting at different levels and interferingwith the replication of some viruses [12] like herpes simplextypes 1 and 2 adenovirus type 2 influenza virus or humanimmunodeficiency virus (HIV) among others [7 60 119ndash124] Table 5 summarizes the antiviral activity of propolis andits chemical constituents

Schnitzler et al [123] analysed the antiviral effect ofPWE and PEE from Czech Republic as well as that ofthe constituents caffeic acid p-coumaric acid benzoic acidgalangin pinocembrin and chrysin against herpes simplexvirus type 1 (HSV-1) in cell culture Both extracts exhibitedhigh anti-HSV-1 activity when cells were treated prior toviral infection galangin and chrysin being the main bioac-tive compounds Amoros et al [60] showed the antiviralactivity of the major flavonoids of propolis more specificallyflavonols and flavones the first being more active againstHSV-1 Additionally they analysed the effect of propolis onseveral DNA and RNA viruses (HSV-1 HSV-2 adenovirustype 2 vesicular stomatitis virus (VSV) and poliovirus type2) Propolis at a concentration of 30120583gmL reduced thetiter of herpes virus however vesicular stomatitis virusand adenovirus were less susceptible In addition propo-lis appears to exert a virucidal action on the envelopedviruses HSV and VSV [120] Recently it was shown thathydromethanolic extract of geopropolis from the stinglessbee Scaptotrigona postica (Brazil) inhibits theHSV replicationand also the entry of the virus into cells effect that wasattributed to the C-glycosyl flavones catechin-3-O-gallate

and 34-dicaffeoylquinic acid [125] According to Tait etal [126] natural and synthetic flavonoids might interferewith picornavirus replication preventing the decapsidationof viral particles and RNA release within cells or blockingviral RNA synthesis These authors also showed that differ-ent homoisoflavonoids have good antiviral activity againstthe coxsackie viruses B3 B4 and A9 and echovirus 30Shvarzbeyn and Huleihel [127] tried to determine whichstep of Tax oncoprotein-induced NF-120581B activation is blockedby propolis and CAPE and showed that both substantiallyinhibited the activation of NF-120581B-dependent promoter byTax Also they strongly prevented both Tax binding to I120581B120572and its induced degradation by Tax Ma et al [128] showedthat nanometer propolis flavones could significantly inhibitin vitro porcine parvovirus (PPV) infecting PK-15 cells andin vivo they restrain the PPV copy in lung gonad and blooddecrease the impact of PPV on weight of guinea pigs andincrease hemagglutination inhibition of PPV in serum as wellas improving the contents of IL-2 IL-6 and 120574-IFN

Over recent years therapeutic benefits of propolis andorits isolated compounds have been described in HIV treat-ment Ito et al [129] tested the anti-HIV activity in H9lymphocytes of triterpenoids melliferone moronic acidanwuweizonic acid and betulonic acid and four knownaromatic compounds isolated from Brazilian propolis andshowed that moronic acid had significant anti-HIV activityGekker et al [119] assessed the anti-HIV-1 activity of propolisin CD4+ lymphocytes and microglial cell cultures observ-ing the inhibition of viral expression in a concentration-dependent wayThe possible mechanism of propolis antiviralproperty was suggested to involve inhibition of viral entry

45 Antimicrobial Activity Antimicrobial activity one ofthe most studied propolis biological properties is very welldocumented This bioactivity has been largely investigatedin the last years due to the need of new treatments againstinfectious diseases especially with the increase of resistantpathogens to current antibiotics Tables 6 and 7 summarisethe antibacterial and antifungal activities found in propolisfrom different geographic origin andor its chemical con-stituents

451 Antibacterial Activity Propolis effect against severalbacterial strains has evaluated [7 56ndash59 130] and supportedthe fact that propolis is more active against Gram-positivebacteria than Gram-negative bacteria [12 59] Briefly datafrom different studies showed that propolis inhibits bac-terial motility and enzyme activity exhibits bacteriostaticactivity against different bacterial genera can be bactericidalin high concentrations and affects cytoplasmic membrane[130]

Mirzoeva et al [130] investigated the effect of PEEon the physiology of Bacillus subtilis Escherichia coli andRhodobacter sphaeroides proposing that propolis and someof its components like cinnamic acid and flavonoids affectthe ion permeability of the inner bacterial membrane causingthe dissipation of the membrane potential and inhibitingbacterial motility A recent study [131] provided valuableinformation for understanding the potential anti-H pylori

mechanism of CAPE H pylori a major factor for gas-trointestinal illnesses contains the enzyme H pylori peptidedeformylase that catalyses the removal of formyl group fromthe N-terminus of nascent polypeptide chains Since theaction of this enzyme is essential for H pylori survival it isconsidered a promising therapeutic drug target Results fromabsorption spectra and crystal structural characterizationshowed that CAPE is a competitive inhibitor of peptidedeformylase blocking the substrate entrance and preventingsubstrate from approaching the active site [131]

It has been suggested that the combination of propoliswith other antibiotics would allow dose reduction of selectedantibiotics thus potentiating their effect The antibacterialactivity of Italian PEE in some clinically isolated Gram-positive strains as well as the synergetic effect with someantibiotics was assessed by Scazzocchio et al [56] Ital-ian PEE drastically increased the effect of ampicillin gen-tamycin and streptomycin and moderated the action ofchloramphenicol ceftriaxone and vancomycin No effectwas observed when used simultaneously with erythromycinWojtyczka et al [132] evaluated the in vitro antimicrobialactivity of a Polish PEE against methicillin-sensitive S aureus(MSSA) and methicillin-resistant S aureus (MRSA) clinicalisolates and also the combined effect of propolis with tenselected antistaphylococcal drugs PEE displayed varyingeffectiveness against twelve S aureus strains and potentiatedthe antimicrobial effect of eight antistaphylococcal againstall tested strains No synergism was observed in the caseof ciprofloxacin and chloramphenicol In another study theeffect of dichloromethane extract of French propolis againstdifferent human pathogenic bacterial strains was also testedAlthough Gram-negative bacteria were not susceptible tothe extract a significant antibacterial activity against bothmethicillin-resistant and methicillin-susceptible S aureusstrains was observed [133] The same was confirmed byVelikova et al [28] using different PEE from BulgariaGreece Turkey and Algeria All the samples showed agood antibacterial activity against S aureus but a week orlacking effect against E coli Australian PEE from stinglessbee Tetragonula carbonaria also inhibited the growth of Saureus Nevertheless it was less active against P aeruginosa[42] The same was observed by Papachroni et al [53]using PEE from Cameroon and CongoContrary to thesestudies Katircioglu and Mercan [134] showed that TurkishPEE was effective against Gram-negative bacteria like E coliOrsi et al [135] investigated the possible synergism betweenBrazilian and Bulgarian propolis and antibiotics acting onDNA (ciprofloxacin and norfloxacin) and on metabolism(cotrimoxazole) in Salmonella typhi Both samples hadantibacterial activity but no synergistic effect was detected

Recently the suitability of nanohydroxyapatite- (nano-HA-) based surfaces containing two Brazilian PEE (greenand red ones) to prevent S aureus bacterial growth andbiofilm was studied The nanoHA impregnated with thetwo highest concentrations (12 and 25120583gmL) of red PEEshowed a remarkable reduction of 99 in the number ofviable bacteria while nanoHA with green PEE at sameconcentrations showed a reduction of 45 and 61 Moreoverthe nanoHA impregnated with the highest concentration of

red PEE was able to inhibit 80 of the staphylococcal biofilmformation [136]

Diverse studies show that as the composition of propolisvaries from region to region the antibacterial activity alsodisplays some variations [59] Susceptibility of differentGram-positive bacteria to PEE varies with the place ofpropolis collection [137] The antibacterial effect was shownto be higher for samples from a wet-tropical rain forest-type climate Other studies revealed the influence of propolisgeographical origin on its antibacterial properties [57 58 138139] Propolis from the north and centre of Portugal has agreat activity against S aureus [58 140]

452 Antifungal Activity Antifungal activity is also influ-enced by the chemical variation of propolis [59] Severalstudies have shown the effect of propolis from differentgeographic origin against different fungi particularly ofclinical interest [141ndash145] Quiroga et al [146] demonstratedthe antifungal activity of propolis from the northwest ofArgentina focusing their study on the environment andthe development of agrochemicals with reduced economiccosts possibly containing propolis extracts and its isolatedcompounds such as pinocembrin and galangin as activeprinciples

Recently Falcao et al [140] screened the antifungalactivity of Portuguese propolis and its potential floral sourcesPopulus x Canadensis and Cistus ladanifer against Candidaalbicans Trichophyton rubrum and Aspergillus fumigatusPlant extracts did not exhibit relevant antifungal activity withexception of T rubrum but both propolis samples revealedsimilar antifungal activity the highest being obtained againstT rubrum and the lowest against A fumigatus A sample ofPEE from Poland showed a high fungicidal activity againstC albicans C glabrata and C krusei [147] Recently it wasshown that different organic extracts of French propolis (PEEPWEmethanolic extract and dichloromethane extract) wereeffective against C albicans and C glabrata but only have aweak activity towards A fumigates [133]

Brazilian PEE was proved to be active against severalCandida strains (C albicans C tropicalis C krusei andC guilliermondii) C albicans being the most sensitive andC guilliermondii the most resistant [141] Brazilian greenand red propolis display activity against different fungalspecies of Trichophyton which cause dermatophytosis redPEE being more efficient than the green one [143] Also itwas shown that n-hexane extract of Brazilian red propolisdid not induce resistance in Candida spp In fact it wasactive against Candida spp resistant to antifungal agentslike fluconazole [148] Dota et al [144] evaluated the in vitroantifungal activity of PEE and propolis microparticles (PMs)obtained from a sample from Argentina against clinical yeastisolates of importance in the vulvovaginal candidiasis Calbicans and non-C albicanswere inhibited by PEE and PMswith small variation Additionally it was shown that Braziliangreen PEE has the ability to inhibit growth and biofilmformation by C albicans from vulvovaginal candidiasis [149]Another study showed fungicide action of propolis (PEEPWE propolis matricial microparticles (PMM) and propolissoluble dry extract after 6ndash8-hour treatment against all three

Evidence-Based Complementary and Alternative Medicine 17

C albicansmorphotypes (yeast pseudohyphae and hyphae)PEE being the most potent followed by PSDE PM andPWE [150] Brazilian propolis induces C albicans cell deathmediated via metacaspase since the metacaspase mutant inC albicans showed reduced sensitivity to propolis and bythe Ras pathway Using C albicans deletion libraries it waspossible to screen several mutants in genes involved eitherin the morphological transitions or in the maintenance of aspecific morphotype that are more sensitive to propolis Toconclude the study the authors also showed that propolisbased gels and cream were partially able to control vulvo-vaginal candidiasis in a mouse model [151] These studies[144] strongly indicate that propolis has a great potential tocontrol vulvovaginal candidiasis representing a promisingalternative therapeutic strategy

46 Antitumour Activity Recognition of the hallmarks ofcancer affects the search and development of new meth-ods and therapeutic agents with a sufficiently large thera-peutic window to kill tumour cells while sparing normalcells In the last years the natural product propolis hasattracted a growing interest by a large number of researcherssince it contains a variety of phytochemical compoundsthat may act through multiple pathways to reduce thedevelopment and other malignant characteristics of cancercells

Recently several in vitro studies have demonstrated acytotoxic action of propolis from different geographic originand of some of its isolated compounds on various tumourcells In vivo studies also show a potential in the developmentof new antitumor agents since propolis administration tomammals (eg rats) does not lead to detectable side effects[3] Briefly this natural product can block specific oncogenesignalling pathways which in turn lead to a decrease in cellproliferation and growth and can also act by decreasing thecancer stem cell population increasing apoptosis exertingantiangiogenic effects and modulating the tumour microen-vironment [66 152 153] Table 8 summarizes the antitumouractivity of propolis from different geographic origin and itschemical constituents

Some researchers showed the effect of different types ofpropolis and its constituents on cancer cell growth prolifera-tion and apoptosisThe hexane extract of propolis fromThai-land collected by the stingless bee Trigona laeviceps whichhas a different behavior in propolis collection compared tothe honey bees exerts antiproliferative activity against fivetested cancer cell lines (Chago KATO-III SW620 BT474and Hep-G2) but not against the normal cell lines tested(HS27 fibroblast and CH-liver) [5] A sample of PEE fromPoland inhibited human malignant melanoma (Me45) andcolorectal cancer (HCT 116) cells growth as well as reducedcell size [154]Other studies reported the antitumor activity ofBrazilianPEE [155ndash158]which regulate the protein expressionof cyclin D1 B1 and cyclin dependent kinase (CDK) as wellas p21 in human prostate cancer cells significantly affectingproliferation [158]

Although propolis containing CAPE is different fromthose with artepillin C it is possible to obtain a similarinhibitory effect from both types The effect of CAPE on

different cancer cell lines was analysed and many of itseffects have been shown to be mediated through inhibitionof NF-120581B [66 159] CAPE can inhibit the proliferation of thecolorectal cell line SW480 by decreasing the 120573-catenin c-myc and cyclin D1 protein expression [160] Chuu et al [161]observed that CAPE suppressed the proliferation of LNCaPDU-145 and PC-3 human prostate cancer cells in a dose-dependent manner and also inhibited the tumour growthof LNCaP xenografts in nude mice It was suggested that itacted through inhibition of p70S6K (an intermediary of thePI3KAKTpathway responsible for the protein synthesis) andsome Akt signalling networks Wu et al [162] demonstratedthat CAPE inhibits in vitro and in vivoMCF-7 andMDA-MB-231 tumour growthwithoutmuch effect on normalmammarycells by reducing the expression of growth and transcriptionfactors including NF-120581B Recently it was demonstrated thatCAPE effect on genes that are associated with tumour cellgrowth and survival is related in part to its role as a histonedeacetylase inhibitor [163]

As previously said propolis can also act by decreasingthe cancer stem cell population Using the putative CD44(+)CD24 (minuslow) breast cancer stem cells able to generatemammospheres from single cells Omene et al [164] showedthat CAPE caused a dose-dependent inhibition of cancerstem cells self-renewal progenitor formation and clonalgrowth

Concerning cell death some in vitro studies showeddifferent sensitivities of tumour cells to propolis extractsPWE from Iraq inhibits the proliferation of HL-60 cellsand leads to downregulation of Bcl-2 and activation of Bax[13] Alizadeh et al [165] investigated the protective effectsof Iranian PEE on N-methyl-N-nitro-N-nitrosoguanidine-(MNNG-) initiated gastric cancer in rats Results showedthat tumour incidence the number of lesions structuralabnormalities and beta-catenin of the animals group treatedwith PEE significantly declined compared with the controlPEE also induced the expression of proapoptotic Bax andreduced antiapoptotic Bcl-2 expression Propolis inhibitscolony formation potential and promotes necrotic changes inHCT-116 cells and decreases mitotic cells and increases p53and Ki-67 expression in HCT-116 tumor-bearing mice [13]Szliszkarsquos group have performed many studies to analyze theantitumour effect of different propolis and its constituentson prostate cancer cells (LNCaP and DU145) [166ndash168]Brazilian green PEE sensitized these cells to TRAIL-induceddeath enhanced the expression of TRAIL-R2 and decreasedthe activity of NF-120581B in LNCaP cells [167] Cotreatment ofTRAIL with artepillin C induced the significant activation ofcaspase-8 and caspase-3 as well as a significant disruption ofthe mitochondrial membrane potential [169] Many studieshave been conducted to understand the pathways involvedin the apoptotic effect of CAPE CAPE induces cell cyclearrest and apoptosis and reduces expression of NF-120581B inMDA-MB-231 and MCF-7 human breast cancer cells [162]In PC3 prostate cancer cells CAPE induced apoptosis in adose-dependent manner that was associated with the loss ofexpression of the inhibitors of apoptosis cIAP-1 cIAP-2 andXIAP [170] Cavaliere et al [171] showed that CAPE treatment

of lymphoblastoid cell line PL104 induced apoptosis throughthe mitochondrial intrinsic pathway

It has been known that cancer microenvironment isvery important for carcinogenesis and it consists of stromalendothelial immune and cancer cells Natural productslike propolis and their constituents have been shown tointerfere with this symbiosis It was demonstrated by Lee et al[172] that CAPE could effectively suppress the adhesion andinvasion potential of human hepatocellular carcinoma cells(SK-Hep1) by inhibiting the expression ofMMP-2 andMMP-9 and NF-120581B

Angiogenesis has a crucial role in tumour growth dueto the requirement of oxygen and nutrients to sustain rapiduncontrolled proliferation and metastization Both tumourand stromal cells can secrete proangiogenic factors thatstimulate the formation andmaintenance of new vessels suchas vascular endothelial growth factor (VEGF) [173] BrazilianPEE could significantly reduce the number of newly formedvessels and suppress the proliferation of human umbilicalvein endothelial cells (HUVECs) [174] this antiangiogeniceffect being mainly mediated via inducing apoptosis in tube-forming endothelial cells through the inactivation of the sur-vival signal ERK12 [175] Yun et al [176] observed that CAPEinhibited angiogenesis using the in vivo assay chick embryochorioallantoic membrane (CAM) CAPE also suppressesVEGF formation by MDA-MB-231 cells and formation ofcapillary-like tubes by endothelial cells [162 177] Extractsof propolis containing artepillin C and CAPE significantlyreduced the newly formed vessels and expression of MMPsand VEGF production from various cells [178] and inaccordance with this study Izuta et al [179] described thatCAPE promotes inhibition of VEGF expression in HUVECcells

The first study on the antitumor activity of Portuguesepropolis was only performed in 2010 Using normal andcancerous renal cells derived from human renal cell carci-noma (RCC) patients in addition to A-498 cell line Valenteet al [64] showed that methanolic extract of Portuguesepropolis exhibited selective toxicity against malignant cellscompared to normal cells and in vitro RCC growth wasstrongly inhibited Recently our group demonstrated theantitumour and antiangiogenic activity of the ethanol extractof Pereiro propolis (P10EE) collected in the district ofGuarda Portugal P10EE affects cell viability of differenttumour cells MDA-MB-231 (breast) and DU145 (prostate)being two of the most sensitive ones but was less cytotoxicagainst nontumour cells and fibroblasts Also it signifi-cantly decreased MDA-MB-231 and DU145 cell prolifera-tion and migration along time with cell cycle changesand increased cell death The significant increase observedin glucose consumption and lactate production could beexplained in MDA-MB-231 by an increased expression ofhypoxia inducible factor-1120572 pyruvate dehydrogenase kinaseglucose transporter 1 lactate dehydrogenase and carbonicanhydrase Furthermore P10EE induced a decrease inHBMECs total biomass and proliferation and decreasedvessel sprouting in the chicken chorioallantoic membrane[23]

5 Conclusions

From ancient to modern times herbs and other plant prod-ucts have been widely used as medicinal agents first in folkmedicine and other activities in many parts of the world andlater developed and improved on a scientific basis into drugsthat are used in the health system Propolis is one of thefew natural products that has maintained its popularity overa long period of time As reviewed here propolis containsa broad spectrum of compounds that may be useful in thetreatment of different pathological conditions In fact there ismuch literature that deals with the in vitro and in vivo biologi-cal properties of propolisThis wide range of bioactivities thecontinuous discovery of new compounds the long history ofpropolis use and its safety profile make propolis a potentialcandidate for drug discovery that may be useful in severalclinical scenarios Nevertheless it is necessary to make aneffort to standardize propolis composition since it seems thatpropolis biological properties and chemical composition notonly are variable but also are strictly linked In our opinionpropolis extracts may be important economically and wouldallow a relatively inexpensive treatment in different diseaseshowever to promote its use in modern medicine it will benecessary to identify and isolate the bioactive compoundsto be tested separately or in combination with other drugsalready available

Drug discovery does not consist only of the isolationof bioactive lead compounds from the natural sources Infact this process continues outside the academic laboratoriesthrough preclinical studies followed by clinical trials Thusdespite the in vitro and in vivo assays which provide newvaluable information on propolis biological properties andmechanisms of action it will be necessary to analyse theeffectiveness of propolis clinically to complement the basicresearch available and to evaluate the potential of propolis inhuman health promotion

concentration of diterpenoids and is found in many regionslike Greece [24 25] Switzerland [26]Malta [27] Turkey [28ndash30] or Algeria [28 31]

Propolis from tropic regions like Brazil CubaVenezuelaand Chile has been attracting much attention in thelast years due to its particular chemical profiles Preny-lated phenylpropanoids prenylated p-coumaric acids ace-tophenones diterpenic acids and caffeoylquinic acids wereshown to be very common and abundant in propolis fromBrazil mainly from the south-eastern region [9 10 21]The flavonoids kaempferide and isosakuranetin and someamounts of kaempferol were also found in Brazilian samples[32] Additionally red propolis from the northeast regionsof Brazil presents high concentrations of phenolic acids andthe flavonoids formononetin isoliquiritigenin liquiritigeninmedicarpin and biochanin A [33ndash35] Cuban propolis hasa peculiar enrichment in polyisoprenylated benzophenonesmore specifically nemorosone and a minor content of amixture of xanthochymol and guttiferone E [9 36] makingthis type of sample chemically distinct from both Europeanand Brazilian propolis Propolis from Venezuela is alsocomposed of polyisoprenylated benzophenones in additionto the usual constituents found in samples of tropical regions[9 37 38]

Information about the chemical composition of Aus-tralian propolis is very limited despite the great biodiversityof the island Propolis from Kangaroo Island is mainlycomposed of stilbenes some of them being prenylated Ad-ditionally it has also some prenylated cinnamic acids andflavonoids [39] like 210158403101584041015840-trimethoxychalcone 21015840-hy-droxy-3101584041015840-dimethoxychalcone 2101584041015840-dihydroxy-31015840-metho-xychalcone 57-dihydroxy-23-dihydroflavonol 3-acetate (pi-nobanksin 3-acetate) and 57-dihydroxy-6-methoxy-23-dihydroflavonol 3-acetate [40] Western Australian propolisis composed of Xanthorrhoeol pterostilbene sakuranetinand pinostrobin [41] Propolis of Australian stingless bees(Tetragonula carbonaria) is composed of C-methylatedflavanones [42]

ldquoPacificrdquo propolis (eg Okinawa Taiwan Hawaii Indo-nesia and Myanmar) is another particular type of propolisA new family of compounds the prenylflavonoids morespecifically isonymphaeol-B was identified in Okinawapropolis although three already known compoundsmdashnym-phaeol-A nymphaeol-B and nymphaeol-Cmdashhave also

been isolated in three samples [43] As Okinawan propolisHawaiian propolis is also composed of nine prenylflavonoids[44] Taiwanese propolis is composed of eight prenylfla-vanones nymphaeol-A nymphaeol-B and nymphaeol-Cpropolins A B and E isonymphaeol B and 31015840-geranyl-naringenin [45] In another sample of the Pacific regionthe Indonesian propolis an inseparable mixture of fouralk(en)ylresorcinols (5-pentadecylresorcinol 5-(81015840Z111015840Z-heptadecadienyl)-resorcinol 5-(111015840Z-heptadecenyl)-resor-cinol and 5-heptadecylresorcinol) along with four prenylfla-vanones propolins D C F and G and three cycloartane-type triterpenes mangiferolic acid isomangiferolic acidand 27-hydroxyisomangiferolic acid was identified [46]Additionally fractioning of propolis extracts from Myanmarled to the isolation of two new cycloartane-type triterpenestogether with 13 cycloartanes and four known prenylatedflavanones [47] Thailand propolis which might bepossibly obtained from Styrax trees comprises not onlythe typical compounds of temperate regions but also thetwo new phenylallylflavanones (710158401015840S)-8-[1-(41015840-hydroxy-31015840-methoxyphenyl)prop-2-en-1-yl]-(2S)-pinocembrin and (E)-cinnamyl-(E)-cinnamylidenate [48] In propolis fromCanaryIslands a different phenolic profile was found furofuranlignans being the main compounds Six furofuran lignanswere isolated and characterized as sesamin episesaminmethyl xanthoxylol aschantin sesartenin and yangambinPropolis also contains sugars and sugar alcohols [10 49]Many studies with African propolis from different regionslike Kenya Cameroon Congo Oman and Ethiopia showedthat triterpenoids are major chemical components [50ndash53]Southern Nigeria propolis is uncommon since it presentsprenylated isoflavonoids like Brazilian red propolis and ahigh abundance of stilbenoid compounds [54]

Propolis additionally contains minerals such as mag-nesium calcium iodine potassium sodium copper zincmanganese and iron some vitamins like B1 B2 B6 CE and D as well as provitamin A a few fatty acids andalso some enzymes derived from bee glandular secretion orpossibly from pollen like succinic dehydrogenase adenosinetriphosphatase glucose-6-phosphatase acid phosphatase120572-amylase 120573-amylase 120572-lactamase 120573-lactamase maltaseesterase and transhydrogenase [17 55] Polysaccharides likestarch and the di- and monosaccharaides glucose fructoseribose rhamnose talose gulose and saccharose are com-monly present in propolis too [55]

4 Biological Properties and TherapeuticActivity of Propolis

Despite propolis popularity over time it is not consid-ered as a therapeutic agent in conventional medicine asthe standardization of chemical composition and biologicalactivity is lacking Such standardization is indispensablefor acceptance in the health system Thus characterizationof different types of propolis according to its plant originand corresponding chemical profile is mandatory Studiesabout propolis bioactivity must start with chemical profilingof the extracts since that information is essential to havedetailed and consistent comparative data between each type

of biological activity and chemical data This informationallows extrapolating the possible activity and mechanism ofaction of new propolis under study and provides substantialclues for the development of new drug candidates [6 9]

In the last decades several studies have demonstrated thebiological and pharmacological actions of different world-wide propolis samplesThe following sections summarize therecent published information about antibacterial and anti-fungal [6 7 56ndash59] antiviral [7 59 60] anti-inflammatory[61] antioxidant [62ndash64] immunomodulatory [6 65 66]and antitumor activities [8 17 23 64 66 67] revealing theinterest of researchers in this bee product and its potentialfor the development of new drugs as well

41 Antioxidant Activity It is well known that an endogenousstimuli like cellular metabolism and exogenous agents likeUV toxins and drugs among others generate reactiveoxygen species (ROS) such as hydrogen peroxide (H

2O2) the

superoxide anion (O2minus) and hydroxyl ion (HOminus) as well as

reactive nitrogen species (RNS) especially nitric oxide (NO)Carbohydrates proteins lipids and nucleic acids amongother biomolecules when exposed to the reactive speciessuffer oxidative modifications that modify the cell and leadto its death [68ndash70] Oxidative stress is responsible for theoccurrence of a wide variety of human diseases such asneurodegenerative [71] or cardiovascular diseases [72 73]cancer [68 74] diabetes [6] and atherosclerosis [75]

In the last years several studies have been performedto evaluate the antioxidant capacity of natural productsPropolis extracts composed of different polyphenols havebeen reported to possess a potent antioxidant activity [7076 77] Additionally the chemical varieties in differentpropolis samples from different regions have an influenceon the antioxidant activity Recently Fabris et al showedthat a sample of Italian and Russian propolis ethanol extract(PEE) which have a similar polyphenolic composition havea similar antioxidant activity while Brazilian PEE whichhave low polyphenolic composition have a weak antioxidantactivity [78] Another study also showed using differentsamples of Transylvania PEE a positive correlation betweenhigh polyphenolic composition and high antioxidant activity[79] Phenolic acids and flavonoids are characterized bya powerful antioxidant activity which is closely related tothe chemical structure of the compounds [80] Briefly theantioxidant activity is exerted by inhibiting the activity ofsome enzymes (eg xanthine oxidase protein kinase Cascorbic acid oxidase cyclooxygenase lipoxygenase Na+K+ATPase and cAMP phosphodiesterase) which inhibit theproduction of ROS species by scavenging interrupting thereactions that lead to the lipid peroxidation by chelatingmetal ions mainly iron and copper that are involved in theprocess of free radical creation or by potentiating the actionof other antioxidants [55] Table 2 summarizes some of thestudies addressing the antioxidant activity of propolis

Moreira et al [62] and Miguel et al [63] proposed thatPortuguese propolis an important source of total phenolsflavones and flavonols could be beneficial for human healthdue to its antioxidant properties Portuguese propolis alsoprotects human erythrocytes from free radicals damaging

by decreasing lipid peroxidation [64] These studies suggestthat Portuguese propolis is a powerful antioxidant agentthat can be used against oxidative stress thus maintainingthe structural and functional integrity of the cells Cuesta-Rubio et al [36] demonstrated that nemorosone the mostabundant polyisoprenylated benzophenone present in Cubanpropolis exhibits antioxidant capacity However when thiscompound suffers methylation a process that facilitates theseparation of the compound from the propolis sample theantioxidant property is abolished Ethyl acetate extract ofKangaroo Island propolis which is rich in stilbenes showeda stronger scavenging activity [39] Yang et al showed thatethyl acetate of propolis collected in Anhui China hasstrong scavenging activity and ferric reducing activity thoseactivities being influenced by caffeic acid phenethyl caffeatecinnamyl caffeate and benzyl caffeate [81] Another studyshowed that samples of methanolic extracts of Algerianpropolis that contains high amounts of caffeic acid estersand flavanones kaempferol and galangin possess strongscavenging activity and ferric reducing activity [31] Uruguaypropolis with high polyphenolic composition inhibits low-density lipoprotein (LDL) peroxidation and protein nitra-tion in vitro Moreover it induces the expression of nitricoxide synthase (eNOS) and inhibits NADPH oxidase inbovine aortic endothelial cells [82] In another study thetopical administration of Romanian PEE in mouse eitherprior to or after UVB exposure significantly attenuated themalondialdehyde (MDA) formation and restored glutathioneperoxidase (GSH-Px) activity [83] Talas et al [84] showedthat Turkish PEE has antioxidant properties in the livertissue of NOS inhibited rats In fact NOS inhibition causedan increase in CAT activity and MDA levels effect thatwas significantly decreased when the rats were treated withPEE It is well known that propolis composition is variablenevertheless one of itsmajor components CAPE (caffeic acidphenethyl ester) plays an important role in the antioxidantactivity [85ndash87]

Antioxidant activity is one of the most studied andimportant activities of propolis though there are no studieswith data on the safe dose to be used in humansThus clinicalstudies using propolis and its active compounds are needed

42 Anti-Inflammatory Activity Inflammation is an eventthat normally occurs in response to the constant exposureto environmental and endogenous stimuli as well as toaccidental damage [61] A complex cascade of chemicalsignals initiates after tissue injury and maintains a hostresponse to repair the injured tissue There are two stagesof inflammation acute and chronic Acute inflammation ismediated through the activation of the immune system cellswhich migrate to the site of damage and release growthfactors cytokines and ROSRNS species Chronic inflamma-tion occurs when the acute inflammation is not successfullyresolved This inflammatory condition plays a critical role inthe pathogenesis of many diseases including atherosclerosiscancer asthma Alzheimerrsquos and Parkinsonism [88 89]

Several studies have associated different types of propolisand its various constituents with anti-inflammatory activ-ity [61 90ndash95] Table 3 summarizes the anti-inflammatory

8 Evidence-Based Complementary and Alternative Medicine

mechanisms investigated with propolis and its chemicalconstituents Recently the role of the flavonoids quercetinflavonols and flavones in modulating inflammatory cellfunction was studied [92] Funakoshi-Tago et al [96] inves-tigated the anti-inflammatory effects of flavonoids isolatedfrom Nepalese PEE on the IL-33 signaling pathway Theisolated flavonoids 3101584041015840-dihydroxy-4-methoxydalbergione4-methoxydalbergion cearoin and chrysin inhibited theexpression of inflammatory genes including IL-6 TNF-120572and IL-13 in bone marrow-derived mast cells (BMMC) andalso inhibited the activation of IKK which leads to thedegradation of I120581B120572 and inhibits the activation of nuclearfactor 120581B (NF-120581B)

The release and oxygenation of arachidonic acid are acritical event in inflammation Mirzoeva and Calder [90]demonstrated that propolis components such as CAPE caf-feic acid quercetin andnaringenin among others inhibit theproduction of eicosanoids In fact these components signif-icantly suppressed the lipoxygenase pathway of arachidonicacid metabolism CAPE being the most potent modulatorAnother study indicated that CAPE treatment improveshepatic steatosis induced by high-fat diet in a mouse modelThis effect was attributed to the reduction of c-Jun-N-terminal kinase (JNK12) andNF-120581B activationwith decreasein COX-2 expression [97] Recently it was reported thatCAPE exhibits inhibitory effects on the production of proin-flammatory cytokines (interleukin-1120573 (IL-1120573)) tumor necro-sis factor-120572 (TNF-120572) and monocyte chemoattractant pro-tein 1 (MCP-1) from lipopolysaccharide- (LPS-) stimulatedRAW2647 macrophages [98] Machado et al [99] showedthat Brazilian green propolis water extracts (PWE) modulatean anti-inflammatory cellular response in the model of LPS-induced pulmonary inflammation by decreasing the numberof macrophages and neutrophils Additionally it induced areduction in the secretion of IL-6 and TNF-120572 and an increasein TGF-120573 and IL-10 Another study showed that Brazilianred PEE promotes a significant decrease in renal macrophageinfiltration in rats with chronic kidney disease [100] Bufaloet al [101] demonstrated that Brazilian PEE and caffeicacid inhibited LPS-induced NO production by RAW2647macrophages acting at the transcriptional level and sug-gesting that their anti-inflammatory effects were mediatedby downregulating NF-120581B p38 MAP kinase and JNK12According to Naito et al [95] topical application of BrazilianPEE is effective in inhibiting carrageenan-induced rat hindpaw edemaThis sample appears to inhibit the chemotaxis ofhuman polymorphonuclear leukocytes (PMNs) which alsocontributes to its anti-inflammatory effects Another studyshowed the topical anti-inflammatory activity of propolisfrom Chile in mice ear with induced-edema In fact PEEfrom Buin Chile was the most active against the inflamma-tion induced by 12-O-tetradeca-noylphorbol-13-acetate andarachidonic acid and also inhibits significantly NO releaseby the macrophages [102] More recently Boudreau et al[103] indicated that CAPE is a potent leukotriene biosynthesisinhibitor in PMNs that blocks 5-lipoxygenase (5-LO) activityand arachidonic acid release A Croatian PEE may improvepsoriatic-like skin lesions whichwere induced in the study byirritant agents like n-hexyl salicylate or di-n-propyl disulfide

by reducing the lipid peroxidation in the skin and totalnumber of inflammatory cells in the skin and peritonealcavity more specially by suppressing functional activity ofmacrophages [104]

43 Immunomodulatory Activity Natural substances areconsidered alternative adjuvant therapies in the treatment ofdifferent diseases due to their immunomodulatory effectsInformation about this type of activity was scarce for propolisuntil the 1990s but published work in the last years has pro-vided information about the influence of different propolissamples on the immune system [65 105ndash112] (Table 4)

In a study using Brazilian green propolis it was seenthat the administration for 3 days of a PEE to male BALBcmice modulated the activation of the initial steps of theimmune response by upregulating toll-like receptor- (TLR-)2 and toll-like receptor-4 expression and proinflammatorycytokines (IL-1 and IL-6) production by macrophages andspleen cells [105] Another study demonstrated that BraziliangreenPEEupregulates TLR-4 andCD80 expression in humanmonocytes as well as TNF-120572 and IL-10 production [113] Itwas also shown that caffeic acid stimulates the activity ofmonocytes againstC albicans but it inhibits TLR-2 andHLA-DR expression as well as TNF-120572 and IL-10 production [114]

Additionally Missima et al [115] showed that Braziliangreen PEE administered to stressed mice reduces the proin-flammatory cytokines IL-1120573 and IL-6 When administered tomelanoma-bearing mice submitted or not to chronic stressit induces high levels of IL-1120573 and IL-6 and also stimu-lates Th1 cytokines production indicating the activation ofantitumour cell-mediated immunity Bachiega et al [116]investigated the immunomodulatory effect of propolis andcinnamic and coumaric acids on cytokines IL-1120573 IL-6 andIL-10 production Peritonealmacrophages fromBALBcmicewere incubated with different concentrations of propolis(5 50 and 100mgwell) and coumaric and cinnamic acid(50 and 100mgwell) Propolis and the acids stimulated IL-1120573 production and significantly inhibited IL-6 productionThen after LPS incubation the inhibitory concentrations ofcinnamic and coumaric acids prevented efficiently its effectson IL-6 production whereas propolis inhibited LPS effectsboth before and after its addition Additionally propolis andcoumaric and cinnamic acids inhibited IL-10 production Astudy which evaluated the effect of Brazilian green propolison macrophage activation by H

2O2and NO metabolite

determination [107] showed that propolis increased H2O2

generation and decreased NO generation which favoursthe microbicidal activity Recently the immunomodulatoryeffect of propolis collected in Brazil was evaluated in Leish-mania (Viannia) braziliensis experimental infection Datashows that macrophages incubated with propolis showed asignificant increase in interiorization and further killing ofparasites Also an increased TNF-120572 production was seen inpropolis-pretreated mice whereas IL-12 was downregulatedduring the infection [117]

The immunomodulatory action of propolis does notoccur only at the macrophage level In fact some studiesshow that this action has also an effect on lymphocyte pro-liferation [106 108] Sa-Nunes et al [108] showed inhibitory

effects of Brazilian green propolis on splenocyte proliferationeffect that was attributed to flavonoids and enhancementeffects on interferon- (IFN-) 120574 production by spleen cellsCAPE displays inhibitory effects on transcription factors NF-120581B and NFAT and as a consequence inhibits IL-2 genetranscription IL-2 receptor expression and proliferation ofhuman T cells [94] This provides new information into themolecular mechanisms involved in the anti-inflammatoryand immunomodulatory activities of propolis CAPE hasvarious biological activities but its effect on the immunomod-ulatory activity remains little studied According to Wanget al [112] CAPE can be useful in the treatment of asthmaand other allergic diseases because it can inhibit cytokinesand chemokines production by human monocyte-deriveddendritic cells (MoDCs) which might be related to theNF-120581B signalling pathway Another study demonstrated forthe first time that Brazilian propolis significantly inhibitedthe generation of Th1 cells Furthermore the effects ofpropolis were investigated on 246-trinitrobenzene sulfonicacid- (TNBS-) induced colitis in a mouse model Propolisreduced the frequency of IFN-120574-producing CD4 T cellsin a dose-dependent way under Th1-polarizing conditionsThe inhibitory effect of propolis on Th1 differentiation wasdemonstrated in vivo too and the severity of colitis inpropolis-fed mice was significantly lower than that of micefed with the control diet [118]

44 Antiviral Activity Propolis comprises a complexity ofcompounds which play a role in antiviral protection Despitethe few data available regarding this activity it was shown thatpropolis from different geographic regions has considerableantiviral activity by acting at different levels and interferingwith the replication of some viruses [12] like herpes simplextypes 1 and 2 adenovirus type 2 influenza virus or humanimmunodeficiency virus (HIV) among others [7 60 119ndash124] Table 5 summarizes the antiviral activity of propolis andits chemical constituents

Schnitzler et al [123] analysed the antiviral effect ofPWE and PEE from Czech Republic as well as that ofthe constituents caffeic acid p-coumaric acid benzoic acidgalangin pinocembrin and chrysin against herpes simplexvirus type 1 (HSV-1) in cell culture Both extracts exhibitedhigh anti-HSV-1 activity when cells were treated prior toviral infection galangin and chrysin being the main bioac-tive compounds Amoros et al [60] showed the antiviralactivity of the major flavonoids of propolis more specificallyflavonols and flavones the first being more active againstHSV-1 Additionally they analysed the effect of propolis onseveral DNA and RNA viruses (HSV-1 HSV-2 adenovirustype 2 vesicular stomatitis virus (VSV) and poliovirus type2) Propolis at a concentration of 30120583gmL reduced thetiter of herpes virus however vesicular stomatitis virusand adenovirus were less susceptible In addition propo-lis appears to exert a virucidal action on the envelopedviruses HSV and VSV [120] Recently it was shown thathydromethanolic extract of geopropolis from the stinglessbee Scaptotrigona postica (Brazil) inhibits theHSV replicationand also the entry of the virus into cells effect that wasattributed to the C-glycosyl flavones catechin-3-O-gallate

and 34-dicaffeoylquinic acid [125] According to Tait etal [126] natural and synthetic flavonoids might interferewith picornavirus replication preventing the decapsidationof viral particles and RNA release within cells or blockingviral RNA synthesis These authors also showed that differ-ent homoisoflavonoids have good antiviral activity againstthe coxsackie viruses B3 B4 and A9 and echovirus 30Shvarzbeyn and Huleihel [127] tried to determine whichstep of Tax oncoprotein-induced NF-120581B activation is blockedby propolis and CAPE and showed that both substantiallyinhibited the activation of NF-120581B-dependent promoter byTax Also they strongly prevented both Tax binding to I120581B120572and its induced degradation by Tax Ma et al [128] showedthat nanometer propolis flavones could significantly inhibitin vitro porcine parvovirus (PPV) infecting PK-15 cells andin vivo they restrain the PPV copy in lung gonad and blooddecrease the impact of PPV on weight of guinea pigs andincrease hemagglutination inhibition of PPV in serum as wellas improving the contents of IL-2 IL-6 and 120574-IFN

Over recent years therapeutic benefits of propolis andorits isolated compounds have been described in HIV treat-ment Ito et al [129] tested the anti-HIV activity in H9lymphocytes of triterpenoids melliferone moronic acidanwuweizonic acid and betulonic acid and four knownaromatic compounds isolated from Brazilian propolis andshowed that moronic acid had significant anti-HIV activityGekker et al [119] assessed the anti-HIV-1 activity of propolisin CD4+ lymphocytes and microglial cell cultures observ-ing the inhibition of viral expression in a concentration-dependent wayThe possible mechanism of propolis antiviralproperty was suggested to involve inhibition of viral entry

45 Antimicrobial Activity Antimicrobial activity one ofthe most studied propolis biological properties is very welldocumented This bioactivity has been largely investigatedin the last years due to the need of new treatments againstinfectious diseases especially with the increase of resistantpathogens to current antibiotics Tables 6 and 7 summarisethe antibacterial and antifungal activities found in propolisfrom different geographic origin andor its chemical con-stituents

451 Antibacterial Activity Propolis effect against severalbacterial strains has evaluated [7 56ndash59 130] and supportedthe fact that propolis is more active against Gram-positivebacteria than Gram-negative bacteria [12 59] Briefly datafrom different studies showed that propolis inhibits bac-terial motility and enzyme activity exhibits bacteriostaticactivity against different bacterial genera can be bactericidalin high concentrations and affects cytoplasmic membrane[130]

Mirzoeva et al [130] investigated the effect of PEEon the physiology of Bacillus subtilis Escherichia coli andRhodobacter sphaeroides proposing that propolis and someof its components like cinnamic acid and flavonoids affectthe ion permeability of the inner bacterial membrane causingthe dissipation of the membrane potential and inhibitingbacterial motility A recent study [131] provided valuableinformation for understanding the potential anti-H pylori

mechanism of CAPE H pylori a major factor for gas-trointestinal illnesses contains the enzyme H pylori peptidedeformylase that catalyses the removal of formyl group fromthe N-terminus of nascent polypeptide chains Since theaction of this enzyme is essential for H pylori survival it isconsidered a promising therapeutic drug target Results fromabsorption spectra and crystal structural characterizationshowed that CAPE is a competitive inhibitor of peptidedeformylase blocking the substrate entrance and preventingsubstrate from approaching the active site [131]

It has been suggested that the combination of propoliswith other antibiotics would allow dose reduction of selectedantibiotics thus potentiating their effect The antibacterialactivity of Italian PEE in some clinically isolated Gram-positive strains as well as the synergetic effect with someantibiotics was assessed by Scazzocchio et al [56] Ital-ian PEE drastically increased the effect of ampicillin gen-tamycin and streptomycin and moderated the action ofchloramphenicol ceftriaxone and vancomycin No effectwas observed when used simultaneously with erythromycinWojtyczka et al [132] evaluated the in vitro antimicrobialactivity of a Polish PEE against methicillin-sensitive S aureus(MSSA) and methicillin-resistant S aureus (MRSA) clinicalisolates and also the combined effect of propolis with tenselected antistaphylococcal drugs PEE displayed varyingeffectiveness against twelve S aureus strains and potentiatedthe antimicrobial effect of eight antistaphylococcal againstall tested strains No synergism was observed in the caseof ciprofloxacin and chloramphenicol In another study theeffect of dichloromethane extract of French propolis againstdifferent human pathogenic bacterial strains was also testedAlthough Gram-negative bacteria were not susceptible tothe extract a significant antibacterial activity against bothmethicillin-resistant and methicillin-susceptible S aureusstrains was observed [133] The same was confirmed byVelikova et al [28] using different PEE from BulgariaGreece Turkey and Algeria All the samples showed agood antibacterial activity against S aureus but a week orlacking effect against E coli Australian PEE from stinglessbee Tetragonula carbonaria also inhibited the growth of Saureus Nevertheless it was less active against P aeruginosa[42] The same was observed by Papachroni et al [53]using PEE from Cameroon and CongoContrary to thesestudies Katircioglu and Mercan [134] showed that TurkishPEE was effective against Gram-negative bacteria like E coliOrsi et al [135] investigated the possible synergism betweenBrazilian and Bulgarian propolis and antibiotics acting onDNA (ciprofloxacin and norfloxacin) and on metabolism(cotrimoxazole) in Salmonella typhi Both samples hadantibacterial activity but no synergistic effect was detected

Recently the suitability of nanohydroxyapatite- (nano-HA-) based surfaces containing two Brazilian PEE (greenand red ones) to prevent S aureus bacterial growth andbiofilm was studied The nanoHA impregnated with thetwo highest concentrations (12 and 25120583gmL) of red PEEshowed a remarkable reduction of 99 in the number ofviable bacteria while nanoHA with green PEE at sameconcentrations showed a reduction of 45 and 61 Moreoverthe nanoHA impregnated with the highest concentration of

red PEE was able to inhibit 80 of the staphylococcal biofilmformation [136]

Diverse studies show that as the composition of propolisvaries from region to region the antibacterial activity alsodisplays some variations [59] Susceptibility of differentGram-positive bacteria to PEE varies with the place ofpropolis collection [137] The antibacterial effect was shownto be higher for samples from a wet-tropical rain forest-type climate Other studies revealed the influence of propolisgeographical origin on its antibacterial properties [57 58 138139] Propolis from the north and centre of Portugal has agreat activity against S aureus [58 140]

452 Antifungal Activity Antifungal activity is also influ-enced by the chemical variation of propolis [59] Severalstudies have shown the effect of propolis from differentgeographic origin against different fungi particularly ofclinical interest [141ndash145] Quiroga et al [146] demonstratedthe antifungal activity of propolis from the northwest ofArgentina focusing their study on the environment andthe development of agrochemicals with reduced economiccosts possibly containing propolis extracts and its isolatedcompounds such as pinocembrin and galangin as activeprinciples

Recently Falcao et al [140] screened the antifungalactivity of Portuguese propolis and its potential floral sourcesPopulus x Canadensis and Cistus ladanifer against Candidaalbicans Trichophyton rubrum and Aspergillus fumigatusPlant extracts did not exhibit relevant antifungal activity withexception of T rubrum but both propolis samples revealedsimilar antifungal activity the highest being obtained againstT rubrum and the lowest against A fumigatus A sample ofPEE from Poland showed a high fungicidal activity againstC albicans C glabrata and C krusei [147] Recently it wasshown that different organic extracts of French propolis (PEEPWEmethanolic extract and dichloromethane extract) wereeffective against C albicans and C glabrata but only have aweak activity towards A fumigates [133]

Brazilian PEE was proved to be active against severalCandida strains (C albicans C tropicalis C krusei andC guilliermondii) C albicans being the most sensitive andC guilliermondii the most resistant [141] Brazilian greenand red propolis display activity against different fungalspecies of Trichophyton which cause dermatophytosis redPEE being more efficient than the green one [143] Also itwas shown that n-hexane extract of Brazilian red propolisdid not induce resistance in Candida spp In fact it wasactive against Candida spp resistant to antifungal agentslike fluconazole [148] Dota et al [144] evaluated the in vitroantifungal activity of PEE and propolis microparticles (PMs)obtained from a sample from Argentina against clinical yeastisolates of importance in the vulvovaginal candidiasis Calbicans and non-C albicanswere inhibited by PEE and PMswith small variation Additionally it was shown that Braziliangreen PEE has the ability to inhibit growth and biofilmformation by C albicans from vulvovaginal candidiasis [149]Another study showed fungicide action of propolis (PEEPWE propolis matricial microparticles (PMM) and propolissoluble dry extract after 6ndash8-hour treatment against all three

Evidence-Based Complementary and Alternative Medicine 17

C albicansmorphotypes (yeast pseudohyphae and hyphae)PEE being the most potent followed by PSDE PM andPWE [150] Brazilian propolis induces C albicans cell deathmediated via metacaspase since the metacaspase mutant inC albicans showed reduced sensitivity to propolis and bythe Ras pathway Using C albicans deletion libraries it waspossible to screen several mutants in genes involved eitherin the morphological transitions or in the maintenance of aspecific morphotype that are more sensitive to propolis Toconclude the study the authors also showed that propolisbased gels and cream were partially able to control vulvo-vaginal candidiasis in a mouse model [151] These studies[144] strongly indicate that propolis has a great potential tocontrol vulvovaginal candidiasis representing a promisingalternative therapeutic strategy

46 Antitumour Activity Recognition of the hallmarks ofcancer affects the search and development of new meth-ods and therapeutic agents with a sufficiently large thera-peutic window to kill tumour cells while sparing normalcells In the last years the natural product propolis hasattracted a growing interest by a large number of researcherssince it contains a variety of phytochemical compoundsthat may act through multiple pathways to reduce thedevelopment and other malignant characteristics of cancercells

Recently several in vitro studies have demonstrated acytotoxic action of propolis from different geographic originand of some of its isolated compounds on various tumourcells In vivo studies also show a potential in the developmentof new antitumor agents since propolis administration tomammals (eg rats) does not lead to detectable side effects[3] Briefly this natural product can block specific oncogenesignalling pathways which in turn lead to a decrease in cellproliferation and growth and can also act by decreasing thecancer stem cell population increasing apoptosis exertingantiangiogenic effects and modulating the tumour microen-vironment [66 152 153] Table 8 summarizes the antitumouractivity of propolis from different geographic origin and itschemical constituents

Some researchers showed the effect of different types ofpropolis and its constituents on cancer cell growth prolifera-tion and apoptosisThe hexane extract of propolis fromThai-land collected by the stingless bee Trigona laeviceps whichhas a different behavior in propolis collection compared tothe honey bees exerts antiproliferative activity against fivetested cancer cell lines (Chago KATO-III SW620 BT474and Hep-G2) but not against the normal cell lines tested(HS27 fibroblast and CH-liver) [5] A sample of PEE fromPoland inhibited human malignant melanoma (Me45) andcolorectal cancer (HCT 116) cells growth as well as reducedcell size [154]Other studies reported the antitumor activity ofBrazilianPEE [155ndash158]which regulate the protein expressionof cyclin D1 B1 and cyclin dependent kinase (CDK) as wellas p21 in human prostate cancer cells significantly affectingproliferation [158]

Although propolis containing CAPE is different fromthose with artepillin C it is possible to obtain a similarinhibitory effect from both types The effect of CAPE on

different cancer cell lines was analysed and many of itseffects have been shown to be mediated through inhibitionof NF-120581B [66 159] CAPE can inhibit the proliferation of thecolorectal cell line SW480 by decreasing the 120573-catenin c-myc and cyclin D1 protein expression [160] Chuu et al [161]observed that CAPE suppressed the proliferation of LNCaPDU-145 and PC-3 human prostate cancer cells in a dose-dependent manner and also inhibited the tumour growthof LNCaP xenografts in nude mice It was suggested that itacted through inhibition of p70S6K (an intermediary of thePI3KAKTpathway responsible for the protein synthesis) andsome Akt signalling networks Wu et al [162] demonstratedthat CAPE inhibits in vitro and in vivoMCF-7 andMDA-MB-231 tumour growthwithoutmuch effect on normalmammarycells by reducing the expression of growth and transcriptionfactors including NF-120581B Recently it was demonstrated thatCAPE effect on genes that are associated with tumour cellgrowth and survival is related in part to its role as a histonedeacetylase inhibitor [163]

As previously said propolis can also act by decreasingthe cancer stem cell population Using the putative CD44(+)CD24 (minuslow) breast cancer stem cells able to generatemammospheres from single cells Omene et al [164] showedthat CAPE caused a dose-dependent inhibition of cancerstem cells self-renewal progenitor formation and clonalgrowth

Concerning cell death some in vitro studies showeddifferent sensitivities of tumour cells to propolis extractsPWE from Iraq inhibits the proliferation of HL-60 cellsand leads to downregulation of Bcl-2 and activation of Bax[13] Alizadeh et al [165] investigated the protective effectsof Iranian PEE on N-methyl-N-nitro-N-nitrosoguanidine-(MNNG-) initiated gastric cancer in rats Results showedthat tumour incidence the number of lesions structuralabnormalities and beta-catenin of the animals group treatedwith PEE significantly declined compared with the controlPEE also induced the expression of proapoptotic Bax andreduced antiapoptotic Bcl-2 expression Propolis inhibitscolony formation potential and promotes necrotic changes inHCT-116 cells and decreases mitotic cells and increases p53and Ki-67 expression in HCT-116 tumor-bearing mice [13]Szliszkarsquos group have performed many studies to analyze theantitumour effect of different propolis and its constituentson prostate cancer cells (LNCaP and DU145) [166ndash168]Brazilian green PEE sensitized these cells to TRAIL-induceddeath enhanced the expression of TRAIL-R2 and decreasedthe activity of NF-120581B in LNCaP cells [167] Cotreatment ofTRAIL with artepillin C induced the significant activation ofcaspase-8 and caspase-3 as well as a significant disruption ofthe mitochondrial membrane potential [169] Many studieshave been conducted to understand the pathways involvedin the apoptotic effect of CAPE CAPE induces cell cyclearrest and apoptosis and reduces expression of NF-120581B inMDA-MB-231 and MCF-7 human breast cancer cells [162]In PC3 prostate cancer cells CAPE induced apoptosis in adose-dependent manner that was associated with the loss ofexpression of the inhibitors of apoptosis cIAP-1 cIAP-2 andXIAP [170] Cavaliere et al [171] showed that CAPE treatment

of lymphoblastoid cell line PL104 induced apoptosis throughthe mitochondrial intrinsic pathway

It has been known that cancer microenvironment isvery important for carcinogenesis and it consists of stromalendothelial immune and cancer cells Natural productslike propolis and their constituents have been shown tointerfere with this symbiosis It was demonstrated by Lee et al[172] that CAPE could effectively suppress the adhesion andinvasion potential of human hepatocellular carcinoma cells(SK-Hep1) by inhibiting the expression ofMMP-2 andMMP-9 and NF-120581B

Angiogenesis has a crucial role in tumour growth dueto the requirement of oxygen and nutrients to sustain rapiduncontrolled proliferation and metastization Both tumourand stromal cells can secrete proangiogenic factors thatstimulate the formation andmaintenance of new vessels suchas vascular endothelial growth factor (VEGF) [173] BrazilianPEE could significantly reduce the number of newly formedvessels and suppress the proliferation of human umbilicalvein endothelial cells (HUVECs) [174] this antiangiogeniceffect being mainly mediated via inducing apoptosis in tube-forming endothelial cells through the inactivation of the sur-vival signal ERK12 [175] Yun et al [176] observed that CAPEinhibited angiogenesis using the in vivo assay chick embryochorioallantoic membrane (CAM) CAPE also suppressesVEGF formation by MDA-MB-231 cells and formation ofcapillary-like tubes by endothelial cells [162 177] Extractsof propolis containing artepillin C and CAPE significantlyreduced the newly formed vessels and expression of MMPsand VEGF production from various cells [178] and inaccordance with this study Izuta et al [179] described thatCAPE promotes inhibition of VEGF expression in HUVECcells

The first study on the antitumor activity of Portuguesepropolis was only performed in 2010 Using normal andcancerous renal cells derived from human renal cell carci-noma (RCC) patients in addition to A-498 cell line Valenteet al [64] showed that methanolic extract of Portuguesepropolis exhibited selective toxicity against malignant cellscompared to normal cells and in vitro RCC growth wasstrongly inhibited Recently our group demonstrated theantitumour and antiangiogenic activity of the ethanol extractof Pereiro propolis (P10EE) collected in the district ofGuarda Portugal P10EE affects cell viability of differenttumour cells MDA-MB-231 (breast) and DU145 (prostate)being two of the most sensitive ones but was less cytotoxicagainst nontumour cells and fibroblasts Also it signifi-cantly decreased MDA-MB-231 and DU145 cell prolifera-tion and migration along time with cell cycle changesand increased cell death The significant increase observedin glucose consumption and lactate production could beexplained in MDA-MB-231 by an increased expression ofhypoxia inducible factor-1120572 pyruvate dehydrogenase kinaseglucose transporter 1 lactate dehydrogenase and carbonicanhydrase Furthermore P10EE induced a decrease inHBMECs total biomass and proliferation and decreasedvessel sprouting in the chicken chorioallantoic membrane[23]

5 Conclusions

From ancient to modern times herbs and other plant prod-ucts have been widely used as medicinal agents first in folkmedicine and other activities in many parts of the world andlater developed and improved on a scientific basis into drugsthat are used in the health system Propolis is one of thefew natural products that has maintained its popularity overa long period of time As reviewed here propolis containsa broad spectrum of compounds that may be useful in thetreatment of different pathological conditions In fact there ismuch literature that deals with the in vitro and in vivo biologi-cal properties of propolisThis wide range of bioactivities thecontinuous discovery of new compounds the long history ofpropolis use and its safety profile make propolis a potentialcandidate for drug discovery that may be useful in severalclinical scenarios Nevertheless it is necessary to make aneffort to standardize propolis composition since it seems thatpropolis biological properties and chemical composition notonly are variable but also are strictly linked In our opinionpropolis extracts may be important economically and wouldallow a relatively inexpensive treatment in different diseaseshowever to promote its use in modern medicine it will benecessary to identify and isolate the bioactive compoundsto be tested separately or in combination with other drugsalready available

Drug discovery does not consist only of the isolationof bioactive lead compounds from the natural sources Infact this process continues outside the academic laboratoriesthrough preclinical studies followed by clinical trials Thusdespite the in vitro and in vivo assays which provide newvaluable information on propolis biological properties andmechanisms of action it will be necessary to analyse theeffectiveness of propolis clinically to complement the basicresearch available and to evaluate the potential of propolis inhuman health promotion

of biological activity and chemical data This informationallows extrapolating the possible activity and mechanism ofaction of new propolis under study and provides substantialclues for the development of new drug candidates [6 9]

In the last decades several studies have demonstrated thebiological and pharmacological actions of different world-wide propolis samplesThe following sections summarize therecent published information about antibacterial and anti-fungal [6 7 56ndash59] antiviral [7 59 60] anti-inflammatory[61] antioxidant [62ndash64] immunomodulatory [6 65 66]and antitumor activities [8 17 23 64 66 67] revealing theinterest of researchers in this bee product and its potentialfor the development of new drugs as well

41 Antioxidant Activity It is well known that an endogenousstimuli like cellular metabolism and exogenous agents likeUV toxins and drugs among others generate reactiveoxygen species (ROS) such as hydrogen peroxide (H

2O2) the

superoxide anion (O2minus) and hydroxyl ion (HOminus) as well as

reactive nitrogen species (RNS) especially nitric oxide (NO)Carbohydrates proteins lipids and nucleic acids amongother biomolecules when exposed to the reactive speciessuffer oxidative modifications that modify the cell and leadto its death [68ndash70] Oxidative stress is responsible for theoccurrence of a wide variety of human diseases such asneurodegenerative [71] or cardiovascular diseases [72 73]cancer [68 74] diabetes [6] and atherosclerosis [75]

In the last years several studies have been performedto evaluate the antioxidant capacity of natural productsPropolis extracts composed of different polyphenols havebeen reported to possess a potent antioxidant activity [7076 77] Additionally the chemical varieties in differentpropolis samples from different regions have an influenceon the antioxidant activity Recently Fabris et al showedthat a sample of Italian and Russian propolis ethanol extract(PEE) which have a similar polyphenolic composition havea similar antioxidant activity while Brazilian PEE whichhave low polyphenolic composition have a weak antioxidantactivity [78] Another study also showed using differentsamples of Transylvania PEE a positive correlation betweenhigh polyphenolic composition and high antioxidant activity[79] Phenolic acids and flavonoids are characterized bya powerful antioxidant activity which is closely related tothe chemical structure of the compounds [80] Briefly theantioxidant activity is exerted by inhibiting the activity ofsome enzymes (eg xanthine oxidase protein kinase Cascorbic acid oxidase cyclooxygenase lipoxygenase Na+K+ATPase and cAMP phosphodiesterase) which inhibit theproduction of ROS species by scavenging interrupting thereactions that lead to the lipid peroxidation by chelatingmetal ions mainly iron and copper that are involved in theprocess of free radical creation or by potentiating the actionof other antioxidants [55] Table 2 summarizes some of thestudies addressing the antioxidant activity of propolis

Moreira et al [62] and Miguel et al [63] proposed thatPortuguese propolis an important source of total phenolsflavones and flavonols could be beneficial for human healthdue to its antioxidant properties Portuguese propolis alsoprotects human erythrocytes from free radicals damaging

by decreasing lipid peroxidation [64] These studies suggestthat Portuguese propolis is a powerful antioxidant agentthat can be used against oxidative stress thus maintainingthe structural and functional integrity of the cells Cuesta-Rubio et al [36] demonstrated that nemorosone the mostabundant polyisoprenylated benzophenone present in Cubanpropolis exhibits antioxidant capacity However when thiscompound suffers methylation a process that facilitates theseparation of the compound from the propolis sample theantioxidant property is abolished Ethyl acetate extract ofKangaroo Island propolis which is rich in stilbenes showeda stronger scavenging activity [39] Yang et al showed thatethyl acetate of propolis collected in Anhui China hasstrong scavenging activity and ferric reducing activity thoseactivities being influenced by caffeic acid phenethyl caffeatecinnamyl caffeate and benzyl caffeate [81] Another studyshowed that samples of methanolic extracts of Algerianpropolis that contains high amounts of caffeic acid estersand flavanones kaempferol and galangin possess strongscavenging activity and ferric reducing activity [31] Uruguaypropolis with high polyphenolic composition inhibits low-density lipoprotein (LDL) peroxidation and protein nitra-tion in vitro Moreover it induces the expression of nitricoxide synthase (eNOS) and inhibits NADPH oxidase inbovine aortic endothelial cells [82] In another study thetopical administration of Romanian PEE in mouse eitherprior to or after UVB exposure significantly attenuated themalondialdehyde (MDA) formation and restored glutathioneperoxidase (GSH-Px) activity [83] Talas et al [84] showedthat Turkish PEE has antioxidant properties in the livertissue of NOS inhibited rats In fact NOS inhibition causedan increase in CAT activity and MDA levels effect thatwas significantly decreased when the rats were treated withPEE It is well known that propolis composition is variablenevertheless one of itsmajor components CAPE (caffeic acidphenethyl ester) plays an important role in the antioxidantactivity [85ndash87]

Antioxidant activity is one of the most studied andimportant activities of propolis though there are no studieswith data on the safe dose to be used in humansThus clinicalstudies using propolis and its active compounds are needed

42 Anti-Inflammatory Activity Inflammation is an eventthat normally occurs in response to the constant exposureto environmental and endogenous stimuli as well as toaccidental damage [61] A complex cascade of chemicalsignals initiates after tissue injury and maintains a hostresponse to repair the injured tissue There are two stagesof inflammation acute and chronic Acute inflammation ismediated through the activation of the immune system cellswhich migrate to the site of damage and release growthfactors cytokines and ROSRNS species Chronic inflamma-tion occurs when the acute inflammation is not successfullyresolved This inflammatory condition plays a critical role inthe pathogenesis of many diseases including atherosclerosiscancer asthma Alzheimerrsquos and Parkinsonism [88 89]

Several studies have associated different types of propolisand its various constituents with anti-inflammatory activ-ity [61 90ndash95] Table 3 summarizes the anti-inflammatory

8 Evidence-Based Complementary and Alternative Medicine

mechanisms investigated with propolis and its chemicalconstituents Recently the role of the flavonoids quercetinflavonols and flavones in modulating inflammatory cellfunction was studied [92] Funakoshi-Tago et al [96] inves-tigated the anti-inflammatory effects of flavonoids isolatedfrom Nepalese PEE on the IL-33 signaling pathway Theisolated flavonoids 3101584041015840-dihydroxy-4-methoxydalbergione4-methoxydalbergion cearoin and chrysin inhibited theexpression of inflammatory genes including IL-6 TNF-120572and IL-13 in bone marrow-derived mast cells (BMMC) andalso inhibited the activation of IKK which leads to thedegradation of I120581B120572 and inhibits the activation of nuclearfactor 120581B (NF-120581B)

The release and oxygenation of arachidonic acid are acritical event in inflammation Mirzoeva and Calder [90]demonstrated that propolis components such as CAPE caf-feic acid quercetin andnaringenin among others inhibit theproduction of eicosanoids In fact these components signif-icantly suppressed the lipoxygenase pathway of arachidonicacid metabolism CAPE being the most potent modulatorAnother study indicated that CAPE treatment improveshepatic steatosis induced by high-fat diet in a mouse modelThis effect was attributed to the reduction of c-Jun-N-terminal kinase (JNK12) andNF-120581B activationwith decreasein COX-2 expression [97] Recently it was reported thatCAPE exhibits inhibitory effects on the production of proin-flammatory cytokines (interleukin-1120573 (IL-1120573)) tumor necro-sis factor-120572 (TNF-120572) and monocyte chemoattractant pro-tein 1 (MCP-1) from lipopolysaccharide- (LPS-) stimulatedRAW2647 macrophages [98] Machado et al [99] showedthat Brazilian green propolis water extracts (PWE) modulatean anti-inflammatory cellular response in the model of LPS-induced pulmonary inflammation by decreasing the numberof macrophages and neutrophils Additionally it induced areduction in the secretion of IL-6 and TNF-120572 and an increasein TGF-120573 and IL-10 Another study showed that Brazilianred PEE promotes a significant decrease in renal macrophageinfiltration in rats with chronic kidney disease [100] Bufaloet al [101] demonstrated that Brazilian PEE and caffeicacid inhibited LPS-induced NO production by RAW2647macrophages acting at the transcriptional level and sug-gesting that their anti-inflammatory effects were mediatedby downregulating NF-120581B p38 MAP kinase and JNK12According to Naito et al [95] topical application of BrazilianPEE is effective in inhibiting carrageenan-induced rat hindpaw edemaThis sample appears to inhibit the chemotaxis ofhuman polymorphonuclear leukocytes (PMNs) which alsocontributes to its anti-inflammatory effects Another studyshowed the topical anti-inflammatory activity of propolisfrom Chile in mice ear with induced-edema In fact PEEfrom Buin Chile was the most active against the inflamma-tion induced by 12-O-tetradeca-noylphorbol-13-acetate andarachidonic acid and also inhibits significantly NO releaseby the macrophages [102] More recently Boudreau et al[103] indicated that CAPE is a potent leukotriene biosynthesisinhibitor in PMNs that blocks 5-lipoxygenase (5-LO) activityand arachidonic acid release A Croatian PEE may improvepsoriatic-like skin lesions whichwere induced in the study byirritant agents like n-hexyl salicylate or di-n-propyl disulfide

by reducing the lipid peroxidation in the skin and totalnumber of inflammatory cells in the skin and peritonealcavity more specially by suppressing functional activity ofmacrophages [104]

43 Immunomodulatory Activity Natural substances areconsidered alternative adjuvant therapies in the treatment ofdifferent diseases due to their immunomodulatory effectsInformation about this type of activity was scarce for propolisuntil the 1990s but published work in the last years has pro-vided information about the influence of different propolissamples on the immune system [65 105ndash112] (Table 4)

In a study using Brazilian green propolis it was seenthat the administration for 3 days of a PEE to male BALBcmice modulated the activation of the initial steps of theimmune response by upregulating toll-like receptor- (TLR-)2 and toll-like receptor-4 expression and proinflammatorycytokines (IL-1 and IL-6) production by macrophages andspleen cells [105] Another study demonstrated that BraziliangreenPEEupregulates TLR-4 andCD80 expression in humanmonocytes as well as TNF-120572 and IL-10 production [113] Itwas also shown that caffeic acid stimulates the activity ofmonocytes againstC albicans but it inhibits TLR-2 andHLA-DR expression as well as TNF-120572 and IL-10 production [114]

Additionally Missima et al [115] showed that Braziliangreen PEE administered to stressed mice reduces the proin-flammatory cytokines IL-1120573 and IL-6 When administered tomelanoma-bearing mice submitted or not to chronic stressit induces high levels of IL-1120573 and IL-6 and also stimu-lates Th1 cytokines production indicating the activation ofantitumour cell-mediated immunity Bachiega et al [116]investigated the immunomodulatory effect of propolis andcinnamic and coumaric acids on cytokines IL-1120573 IL-6 andIL-10 production Peritonealmacrophages fromBALBcmicewere incubated with different concentrations of propolis(5 50 and 100mgwell) and coumaric and cinnamic acid(50 and 100mgwell) Propolis and the acids stimulated IL-1120573 production and significantly inhibited IL-6 productionThen after LPS incubation the inhibitory concentrations ofcinnamic and coumaric acids prevented efficiently its effectson IL-6 production whereas propolis inhibited LPS effectsboth before and after its addition Additionally propolis andcoumaric and cinnamic acids inhibited IL-10 production Astudy which evaluated the effect of Brazilian green propolison macrophage activation by H

2O2and NO metabolite

determination [107] showed that propolis increased H2O2

generation and decreased NO generation which favoursthe microbicidal activity Recently the immunomodulatoryeffect of propolis collected in Brazil was evaluated in Leish-mania (Viannia) braziliensis experimental infection Datashows that macrophages incubated with propolis showed asignificant increase in interiorization and further killing ofparasites Also an increased TNF-120572 production was seen inpropolis-pretreated mice whereas IL-12 was downregulatedduring the infection [117]

The immunomodulatory action of propolis does notoccur only at the macrophage level In fact some studiesshow that this action has also an effect on lymphocyte pro-liferation [106 108] Sa-Nunes et al [108] showed inhibitory

10 Evidence-Based Complementary and Alternative Medicine

effects of Brazilian green propolis on splenocyte proliferationeffect that was attributed to flavonoids and enhancementeffects on interferon- (IFN-) 120574 production by spleen cellsCAPE displays inhibitory effects on transcription factors NF-120581B and NFAT and as a consequence inhibits IL-2 genetranscription IL-2 receptor expression and proliferation ofhuman T cells [94] This provides new information into themolecular mechanisms involved in the anti-inflammatoryand immunomodulatory activities of propolis CAPE hasvarious biological activities but its effect on the immunomod-ulatory activity remains little studied According to Wanget al [112] CAPE can be useful in the treatment of asthmaand other allergic diseases because it can inhibit cytokinesand chemokines production by human monocyte-deriveddendritic cells (MoDCs) which might be related to theNF-120581B signalling pathway Another study demonstrated forthe first time that Brazilian propolis significantly inhibitedthe generation of Th1 cells Furthermore the effects ofpropolis were investigated on 246-trinitrobenzene sulfonicacid- (TNBS-) induced colitis in a mouse model Propolisreduced the frequency of IFN-120574-producing CD4 T cellsin a dose-dependent way under Th1-polarizing conditionsThe inhibitory effect of propolis on Th1 differentiation wasdemonstrated in vivo too and the severity of colitis inpropolis-fed mice was significantly lower than that of micefed with the control diet [118]

44 Antiviral Activity Propolis comprises a complexity ofcompounds which play a role in antiviral protection Despitethe few data available regarding this activity it was shown thatpropolis from different geographic regions has considerableantiviral activity by acting at different levels and interferingwith the replication of some viruses [12] like herpes simplextypes 1 and 2 adenovirus type 2 influenza virus or humanimmunodeficiency virus (HIV) among others [7 60 119ndash124] Table 5 summarizes the antiviral activity of propolis andits chemical constituents

Schnitzler et al [123] analysed the antiviral effect ofPWE and PEE from Czech Republic as well as that ofthe constituents caffeic acid p-coumaric acid benzoic acidgalangin pinocembrin and chrysin against herpes simplexvirus type 1 (HSV-1) in cell culture Both extracts exhibitedhigh anti-HSV-1 activity when cells were treated prior toviral infection galangin and chrysin being the main bioac-tive compounds Amoros et al [60] showed the antiviralactivity of the major flavonoids of propolis more specificallyflavonols and flavones the first being more active againstHSV-1 Additionally they analysed the effect of propolis onseveral DNA and RNA viruses (HSV-1 HSV-2 adenovirustype 2 vesicular stomatitis virus (VSV) and poliovirus type2) Propolis at a concentration of 30120583gmL reduced thetiter of herpes virus however vesicular stomatitis virusand adenovirus were less susceptible In addition propo-lis appears to exert a virucidal action on the envelopedviruses HSV and VSV [120] Recently it was shown thathydromethanolic extract of geopropolis from the stinglessbee Scaptotrigona postica (Brazil) inhibits theHSV replicationand also the entry of the virus into cells effect that wasattributed to the C-glycosyl flavones catechin-3-O-gallate

and 34-dicaffeoylquinic acid [125] According to Tait etal [126] natural and synthetic flavonoids might interferewith picornavirus replication preventing the decapsidationof viral particles and RNA release within cells or blockingviral RNA synthesis These authors also showed that differ-ent homoisoflavonoids have good antiviral activity againstthe coxsackie viruses B3 B4 and A9 and echovirus 30Shvarzbeyn and Huleihel [127] tried to determine whichstep of Tax oncoprotein-induced NF-120581B activation is blockedby propolis and CAPE and showed that both substantiallyinhibited the activation of NF-120581B-dependent promoter byTax Also they strongly prevented both Tax binding to I120581B120572and its induced degradation by Tax Ma et al [128] showedthat nanometer propolis flavones could significantly inhibitin vitro porcine parvovirus (PPV) infecting PK-15 cells andin vivo they restrain the PPV copy in lung gonad and blooddecrease the impact of PPV on weight of guinea pigs andincrease hemagglutination inhibition of PPV in serum as wellas improving the contents of IL-2 IL-6 and 120574-IFN

Over recent years therapeutic benefits of propolis andorits isolated compounds have been described in HIV treat-ment Ito et al [129] tested the anti-HIV activity in H9lymphocytes of triterpenoids melliferone moronic acidanwuweizonic acid and betulonic acid and four knownaromatic compounds isolated from Brazilian propolis andshowed that moronic acid had significant anti-HIV activityGekker et al [119] assessed the anti-HIV-1 activity of propolisin CD4+ lymphocytes and microglial cell cultures observ-ing the inhibition of viral expression in a concentration-dependent wayThe possible mechanism of propolis antiviralproperty was suggested to involve inhibition of viral entry

45 Antimicrobial Activity Antimicrobial activity one ofthe most studied propolis biological properties is very welldocumented This bioactivity has been largely investigatedin the last years due to the need of new treatments againstinfectious diseases especially with the increase of resistantpathogens to current antibiotics Tables 6 and 7 summarisethe antibacterial and antifungal activities found in propolisfrom different geographic origin andor its chemical con-stituents

451 Antibacterial Activity Propolis effect against severalbacterial strains has evaluated [7 56ndash59 130] and supportedthe fact that propolis is more active against Gram-positivebacteria than Gram-negative bacteria [12 59] Briefly datafrom different studies showed that propolis inhibits bac-terial motility and enzyme activity exhibits bacteriostaticactivity against different bacterial genera can be bactericidalin high concentrations and affects cytoplasmic membrane[130]

Mirzoeva et al [130] investigated the effect of PEEon the physiology of Bacillus subtilis Escherichia coli andRhodobacter sphaeroides proposing that propolis and someof its components like cinnamic acid and flavonoids affectthe ion permeability of the inner bacterial membrane causingthe dissipation of the membrane potential and inhibitingbacterial motility A recent study [131] provided valuableinformation for understanding the potential anti-H pylori

mechanism of CAPE H pylori a major factor for gas-trointestinal illnesses contains the enzyme H pylori peptidedeformylase that catalyses the removal of formyl group fromthe N-terminus of nascent polypeptide chains Since theaction of this enzyme is essential for H pylori survival it isconsidered a promising therapeutic drug target Results fromabsorption spectra and crystal structural characterizationshowed that CAPE is a competitive inhibitor of peptidedeformylase blocking the substrate entrance and preventingsubstrate from approaching the active site [131]

It has been suggested that the combination of propoliswith other antibiotics would allow dose reduction of selectedantibiotics thus potentiating their effect The antibacterialactivity of Italian PEE in some clinically isolated Gram-positive strains as well as the synergetic effect with someantibiotics was assessed by Scazzocchio et al [56] Ital-ian PEE drastically increased the effect of ampicillin gen-tamycin and streptomycin and moderated the action ofchloramphenicol ceftriaxone and vancomycin No effectwas observed when used simultaneously with erythromycinWojtyczka et al [132] evaluated the in vitro antimicrobialactivity of a Polish PEE against methicillin-sensitive S aureus(MSSA) and methicillin-resistant S aureus (MRSA) clinicalisolates and also the combined effect of propolis with tenselected antistaphylococcal drugs PEE displayed varyingeffectiveness against twelve S aureus strains and potentiatedthe antimicrobial effect of eight antistaphylococcal againstall tested strains No synergism was observed in the caseof ciprofloxacin and chloramphenicol In another study theeffect of dichloromethane extract of French propolis againstdifferent human pathogenic bacterial strains was also testedAlthough Gram-negative bacteria were not susceptible tothe extract a significant antibacterial activity against bothmethicillin-resistant and methicillin-susceptible S aureusstrains was observed [133] The same was confirmed byVelikova et al [28] using different PEE from BulgariaGreece Turkey and Algeria All the samples showed agood antibacterial activity against S aureus but a week orlacking effect against E coli Australian PEE from stinglessbee Tetragonula carbonaria also inhibited the growth of Saureus Nevertheless it was less active against P aeruginosa[42] The same was observed by Papachroni et al [53]using PEE from Cameroon and CongoContrary to thesestudies Katircioglu and Mercan [134] showed that TurkishPEE was effective against Gram-negative bacteria like E coliOrsi et al [135] investigated the possible synergism betweenBrazilian and Bulgarian propolis and antibiotics acting onDNA (ciprofloxacin and norfloxacin) and on metabolism(cotrimoxazole) in Salmonella typhi Both samples hadantibacterial activity but no synergistic effect was detected

Recently the suitability of nanohydroxyapatite- (nano-HA-) based surfaces containing two Brazilian PEE (greenand red ones) to prevent S aureus bacterial growth andbiofilm was studied The nanoHA impregnated with thetwo highest concentrations (12 and 25120583gmL) of red PEEshowed a remarkable reduction of 99 in the number ofviable bacteria while nanoHA with green PEE at sameconcentrations showed a reduction of 45 and 61 Moreoverthe nanoHA impregnated with the highest concentration of

red PEE was able to inhibit 80 of the staphylococcal biofilmformation [136]

Diverse studies show that as the composition of propolisvaries from region to region the antibacterial activity alsodisplays some variations [59] Susceptibility of differentGram-positive bacteria to PEE varies with the place ofpropolis collection [137] The antibacterial effect was shownto be higher for samples from a wet-tropical rain forest-type climate Other studies revealed the influence of propolisgeographical origin on its antibacterial properties [57 58 138139] Propolis from the north and centre of Portugal has agreat activity against S aureus [58 140]

452 Antifungal Activity Antifungal activity is also influ-enced by the chemical variation of propolis [59] Severalstudies have shown the effect of propolis from differentgeographic origin against different fungi particularly ofclinical interest [141ndash145] Quiroga et al [146] demonstratedthe antifungal activity of propolis from the northwest ofArgentina focusing their study on the environment andthe development of agrochemicals with reduced economiccosts possibly containing propolis extracts and its isolatedcompounds such as pinocembrin and galangin as activeprinciples

Recently Falcao et al [140] screened the antifungalactivity of Portuguese propolis and its potential floral sourcesPopulus x Canadensis and Cistus ladanifer against Candidaalbicans Trichophyton rubrum and Aspergillus fumigatusPlant extracts did not exhibit relevant antifungal activity withexception of T rubrum but both propolis samples revealedsimilar antifungal activity the highest being obtained againstT rubrum and the lowest against A fumigatus A sample ofPEE from Poland showed a high fungicidal activity againstC albicans C glabrata and C krusei [147] Recently it wasshown that different organic extracts of French propolis (PEEPWEmethanolic extract and dichloromethane extract) wereeffective against C albicans and C glabrata but only have aweak activity towards A fumigates [133]

Brazilian PEE was proved to be active against severalCandida strains (C albicans C tropicalis C krusei andC guilliermondii) C albicans being the most sensitive andC guilliermondii the most resistant [141] Brazilian greenand red propolis display activity against different fungalspecies of Trichophyton which cause dermatophytosis redPEE being more efficient than the green one [143] Also itwas shown that n-hexane extract of Brazilian red propolisdid not induce resistance in Candida spp In fact it wasactive against Candida spp resistant to antifungal agentslike fluconazole [148] Dota et al [144] evaluated the in vitroantifungal activity of PEE and propolis microparticles (PMs)obtained from a sample from Argentina against clinical yeastisolates of importance in the vulvovaginal candidiasis Calbicans and non-C albicanswere inhibited by PEE and PMswith small variation Additionally it was shown that Braziliangreen PEE has the ability to inhibit growth and biofilmformation by C albicans from vulvovaginal candidiasis [149]Another study showed fungicide action of propolis (PEEPWE propolis matricial microparticles (PMM) and propolissoluble dry extract after 6ndash8-hour treatment against all three

Evidence-Based Complementary and Alternative Medicine 17

C albicansmorphotypes (yeast pseudohyphae and hyphae)PEE being the most potent followed by PSDE PM andPWE [150] Brazilian propolis induces C albicans cell deathmediated via metacaspase since the metacaspase mutant inC albicans showed reduced sensitivity to propolis and bythe Ras pathway Using C albicans deletion libraries it waspossible to screen several mutants in genes involved eitherin the morphological transitions or in the maintenance of aspecific morphotype that are more sensitive to propolis Toconclude the study the authors also showed that propolisbased gels and cream were partially able to control vulvo-vaginal candidiasis in a mouse model [151] These studies[144] strongly indicate that propolis has a great potential tocontrol vulvovaginal candidiasis representing a promisingalternative therapeutic strategy

46 Antitumour Activity Recognition of the hallmarks ofcancer affects the search and development of new meth-ods and therapeutic agents with a sufficiently large thera-peutic window to kill tumour cells while sparing normalcells In the last years the natural product propolis hasattracted a growing interest by a large number of researcherssince it contains a variety of phytochemical compoundsthat may act through multiple pathways to reduce thedevelopment and other malignant characteristics of cancercells

Recently several in vitro studies have demonstrated acytotoxic action of propolis from different geographic originand of some of its isolated compounds on various tumourcells In vivo studies also show a potential in the developmentof new antitumor agents since propolis administration tomammals (eg rats) does not lead to detectable side effects[3] Briefly this natural product can block specific oncogenesignalling pathways which in turn lead to a decrease in cellproliferation and growth and can also act by decreasing thecancer stem cell population increasing apoptosis exertingantiangiogenic effects and modulating the tumour microen-vironment [66 152 153] Table 8 summarizes the antitumouractivity of propolis from different geographic origin and itschemical constituents

Some researchers showed the effect of different types ofpropolis and its constituents on cancer cell growth prolifera-tion and apoptosisThe hexane extract of propolis fromThai-land collected by the stingless bee Trigona laeviceps whichhas a different behavior in propolis collection compared tothe honey bees exerts antiproliferative activity against fivetested cancer cell lines (Chago KATO-III SW620 BT474and Hep-G2) but not against the normal cell lines tested(HS27 fibroblast and CH-liver) [5] A sample of PEE fromPoland inhibited human malignant melanoma (Me45) andcolorectal cancer (HCT 116) cells growth as well as reducedcell size [154]Other studies reported the antitumor activity ofBrazilianPEE [155ndash158]which regulate the protein expressionof cyclin D1 B1 and cyclin dependent kinase (CDK) as wellas p21 in human prostate cancer cells significantly affectingproliferation [158]

Although propolis containing CAPE is different fromthose with artepillin C it is possible to obtain a similarinhibitory effect from both types The effect of CAPE on

different cancer cell lines was analysed and many of itseffects have been shown to be mediated through inhibitionof NF-120581B [66 159] CAPE can inhibit the proliferation of thecolorectal cell line SW480 by decreasing the 120573-catenin c-myc and cyclin D1 protein expression [160] Chuu et al [161]observed that CAPE suppressed the proliferation of LNCaPDU-145 and PC-3 human prostate cancer cells in a dose-dependent manner and also inhibited the tumour growthof LNCaP xenografts in nude mice It was suggested that itacted through inhibition of p70S6K (an intermediary of thePI3KAKTpathway responsible for the protein synthesis) andsome Akt signalling networks Wu et al [162] demonstratedthat CAPE inhibits in vitro and in vivoMCF-7 andMDA-MB-231 tumour growthwithoutmuch effect on normalmammarycells by reducing the expression of growth and transcriptionfactors including NF-120581B Recently it was demonstrated thatCAPE effect on genes that are associated with tumour cellgrowth and survival is related in part to its role as a histonedeacetylase inhibitor [163]

As previously said propolis can also act by decreasingthe cancer stem cell population Using the putative CD44(+)CD24 (minuslow) breast cancer stem cells able to generatemammospheres from single cells Omene et al [164] showedthat CAPE caused a dose-dependent inhibition of cancerstem cells self-renewal progenitor formation and clonalgrowth

Concerning cell death some in vitro studies showeddifferent sensitivities of tumour cells to propolis extractsPWE from Iraq inhibits the proliferation of HL-60 cellsand leads to downregulation of Bcl-2 and activation of Bax[13] Alizadeh et al [165] investigated the protective effectsof Iranian PEE on N-methyl-N-nitro-N-nitrosoguanidine-(MNNG-) initiated gastric cancer in rats Results showedthat tumour incidence the number of lesions structuralabnormalities and beta-catenin of the animals group treatedwith PEE significantly declined compared with the controlPEE also induced the expression of proapoptotic Bax andreduced antiapoptotic Bcl-2 expression Propolis inhibitscolony formation potential and promotes necrotic changes inHCT-116 cells and decreases mitotic cells and increases p53and Ki-67 expression in HCT-116 tumor-bearing mice [13]Szliszkarsquos group have performed many studies to analyze theantitumour effect of different propolis and its constituentson prostate cancer cells (LNCaP and DU145) [166ndash168]Brazilian green PEE sensitized these cells to TRAIL-induceddeath enhanced the expression of TRAIL-R2 and decreasedthe activity of NF-120581B in LNCaP cells [167] Cotreatment ofTRAIL with artepillin C induced the significant activation ofcaspase-8 and caspase-3 as well as a significant disruption ofthe mitochondrial membrane potential [169] Many studieshave been conducted to understand the pathways involvedin the apoptotic effect of CAPE CAPE induces cell cyclearrest and apoptosis and reduces expression of NF-120581B inMDA-MB-231 and MCF-7 human breast cancer cells [162]In PC3 prostate cancer cells CAPE induced apoptosis in adose-dependent manner that was associated with the loss ofexpression of the inhibitors of apoptosis cIAP-1 cIAP-2 andXIAP [170] Cavaliere et al [171] showed that CAPE treatment

of lymphoblastoid cell line PL104 induced apoptosis throughthe mitochondrial intrinsic pathway

It has been known that cancer microenvironment isvery important for carcinogenesis and it consists of stromalendothelial immune and cancer cells Natural productslike propolis and their constituents have been shown tointerfere with this symbiosis It was demonstrated by Lee et al[172] that CAPE could effectively suppress the adhesion andinvasion potential of human hepatocellular carcinoma cells(SK-Hep1) by inhibiting the expression ofMMP-2 andMMP-9 and NF-120581B

Angiogenesis has a crucial role in tumour growth dueto the requirement of oxygen and nutrients to sustain rapiduncontrolled proliferation and metastization Both tumourand stromal cells can secrete proangiogenic factors thatstimulate the formation andmaintenance of new vessels suchas vascular endothelial growth factor (VEGF) [173] BrazilianPEE could significantly reduce the number of newly formedvessels and suppress the proliferation of human umbilicalvein endothelial cells (HUVECs) [174] this antiangiogeniceffect being mainly mediated via inducing apoptosis in tube-forming endothelial cells through the inactivation of the sur-vival signal ERK12 [175] Yun et al [176] observed that CAPEinhibited angiogenesis using the in vivo assay chick embryochorioallantoic membrane (CAM) CAPE also suppressesVEGF formation by MDA-MB-231 cells and formation ofcapillary-like tubes by endothelial cells [162 177] Extractsof propolis containing artepillin C and CAPE significantlyreduced the newly formed vessels and expression of MMPsand VEGF production from various cells [178] and inaccordance with this study Izuta et al [179] described thatCAPE promotes inhibition of VEGF expression in HUVECcells

The first study on the antitumor activity of Portuguesepropolis was only performed in 2010 Using normal andcancerous renal cells derived from human renal cell carci-noma (RCC) patients in addition to A-498 cell line Valenteet al [64] showed that methanolic extract of Portuguesepropolis exhibited selective toxicity against malignant cellscompared to normal cells and in vitro RCC growth wasstrongly inhibited Recently our group demonstrated theantitumour and antiangiogenic activity of the ethanol extractof Pereiro propolis (P10EE) collected in the district ofGuarda Portugal P10EE affects cell viability of differenttumour cells MDA-MB-231 (breast) and DU145 (prostate)being two of the most sensitive ones but was less cytotoxicagainst nontumour cells and fibroblasts Also it signifi-cantly decreased MDA-MB-231 and DU145 cell prolifera-tion and migration along time with cell cycle changesand increased cell death The significant increase observedin glucose consumption and lactate production could beexplained in MDA-MB-231 by an increased expression ofhypoxia inducible factor-1120572 pyruvate dehydrogenase kinaseglucose transporter 1 lactate dehydrogenase and carbonicanhydrase Furthermore P10EE induced a decrease inHBMECs total biomass and proliferation and decreasedvessel sprouting in the chicken chorioallantoic membrane[23]

5 Conclusions

From ancient to modern times herbs and other plant prod-ucts have been widely used as medicinal agents first in folkmedicine and other activities in many parts of the world andlater developed and improved on a scientific basis into drugsthat are used in the health system Propolis is one of thefew natural products that has maintained its popularity overa long period of time As reviewed here propolis containsa broad spectrum of compounds that may be useful in thetreatment of different pathological conditions In fact there ismuch literature that deals with the in vitro and in vivo biologi-cal properties of propolisThis wide range of bioactivities thecontinuous discovery of new compounds the long history ofpropolis use and its safety profile make propolis a potentialcandidate for drug discovery that may be useful in severalclinical scenarios Nevertheless it is necessary to make aneffort to standardize propolis composition since it seems thatpropolis biological properties and chemical composition notonly are variable but also are strictly linked In our opinionpropolis extracts may be important economically and wouldallow a relatively inexpensive treatment in different diseaseshowever to promote its use in modern medicine it will benecessary to identify and isolate the bioactive compoundsto be tested separately or in combination with other drugsalready available

Drug discovery does not consist only of the isolationof bioactive lead compounds from the natural sources Infact this process continues outside the academic laboratoriesthrough preclinical studies followed by clinical trials Thusdespite the in vitro and in vivo assays which provide newvaluable information on propolis biological properties andmechanisms of action it will be necessary to analyse theeffectiveness of propolis clinically to complement the basicresearch available and to evaluate the potential of propolis inhuman health promotion

of biological activity and chemical data This informationallows extrapolating the possible activity and mechanism ofaction of new propolis under study and provides substantialclues for the development of new drug candidates [6 9]

In the last decades several studies have demonstrated thebiological and pharmacological actions of different world-wide propolis samplesThe following sections summarize therecent published information about antibacterial and anti-fungal [6 7 56ndash59] antiviral [7 59 60] anti-inflammatory[61] antioxidant [62ndash64] immunomodulatory [6 65 66]and antitumor activities [8 17 23 64 66 67] revealing theinterest of researchers in this bee product and its potentialfor the development of new drugs as well

41 Antioxidant Activity It is well known that an endogenousstimuli like cellular metabolism and exogenous agents likeUV toxins and drugs among others generate reactiveoxygen species (ROS) such as hydrogen peroxide (H

2O2) the

superoxide anion (O2minus) and hydroxyl ion (HOminus) as well as

reactive nitrogen species (RNS) especially nitric oxide (NO)Carbohydrates proteins lipids and nucleic acids amongother biomolecules when exposed to the reactive speciessuffer oxidative modifications that modify the cell and leadto its death [68ndash70] Oxidative stress is responsible for theoccurrence of a wide variety of human diseases such asneurodegenerative [71] or cardiovascular diseases [72 73]cancer [68 74] diabetes [6] and atherosclerosis [75]

In the last years several studies have been performedto evaluate the antioxidant capacity of natural productsPropolis extracts composed of different polyphenols havebeen reported to possess a potent antioxidant activity [7076 77] Additionally the chemical varieties in differentpropolis samples from different regions have an influenceon the antioxidant activity Recently Fabris et al showedthat a sample of Italian and Russian propolis ethanol extract(PEE) which have a similar polyphenolic composition havea similar antioxidant activity while Brazilian PEE whichhave low polyphenolic composition have a weak antioxidantactivity [78] Another study also showed using differentsamples of Transylvania PEE a positive correlation betweenhigh polyphenolic composition and high antioxidant activity[79] Phenolic acids and flavonoids are characterized bya powerful antioxidant activity which is closely related tothe chemical structure of the compounds [80] Briefly theantioxidant activity is exerted by inhibiting the activity ofsome enzymes (eg xanthine oxidase protein kinase Cascorbic acid oxidase cyclooxygenase lipoxygenase Na+K+ATPase and cAMP phosphodiesterase) which inhibit theproduction of ROS species by scavenging interrupting thereactions that lead to the lipid peroxidation by chelatingmetal ions mainly iron and copper that are involved in theprocess of free radical creation or by potentiating the actionof other antioxidants [55] Table 2 summarizes some of thestudies addressing the antioxidant activity of propolis

Moreira et al [62] and Miguel et al [63] proposed thatPortuguese propolis an important source of total phenolsflavones and flavonols could be beneficial for human healthdue to its antioxidant properties Portuguese propolis alsoprotects human erythrocytes from free radicals damaging

by decreasing lipid peroxidation [64] These studies suggestthat Portuguese propolis is a powerful antioxidant agentthat can be used against oxidative stress thus maintainingthe structural and functional integrity of the cells Cuesta-Rubio et al [36] demonstrated that nemorosone the mostabundant polyisoprenylated benzophenone present in Cubanpropolis exhibits antioxidant capacity However when thiscompound suffers methylation a process that facilitates theseparation of the compound from the propolis sample theantioxidant property is abolished Ethyl acetate extract ofKangaroo Island propolis which is rich in stilbenes showeda stronger scavenging activity [39] Yang et al showed thatethyl acetate of propolis collected in Anhui China hasstrong scavenging activity and ferric reducing activity thoseactivities being influenced by caffeic acid phenethyl caffeatecinnamyl caffeate and benzyl caffeate [81] Another studyshowed that samples of methanolic extracts of Algerianpropolis that contains high amounts of caffeic acid estersand flavanones kaempferol and galangin possess strongscavenging activity and ferric reducing activity [31] Uruguaypropolis with high polyphenolic composition inhibits low-density lipoprotein (LDL) peroxidation and protein nitra-tion in vitro Moreover it induces the expression of nitricoxide synthase (eNOS) and inhibits NADPH oxidase inbovine aortic endothelial cells [82] In another study thetopical administration of Romanian PEE in mouse eitherprior to or after UVB exposure significantly attenuated themalondialdehyde (MDA) formation and restored glutathioneperoxidase (GSH-Px) activity [83] Talas et al [84] showedthat Turkish PEE has antioxidant properties in the livertissue of NOS inhibited rats In fact NOS inhibition causedan increase in CAT activity and MDA levels effect thatwas significantly decreased when the rats were treated withPEE It is well known that propolis composition is variablenevertheless one of itsmajor components CAPE (caffeic acidphenethyl ester) plays an important role in the antioxidantactivity [85ndash87]

Antioxidant activity is one of the most studied andimportant activities of propolis though there are no studieswith data on the safe dose to be used in humansThus clinicalstudies using propolis and its active compounds are needed

42 Anti-Inflammatory Activity Inflammation is an eventthat normally occurs in response to the constant exposureto environmental and endogenous stimuli as well as toaccidental damage [61] A complex cascade of chemicalsignals initiates after tissue injury and maintains a hostresponse to repair the injured tissue There are two stagesof inflammation acute and chronic Acute inflammation ismediated through the activation of the immune system cellswhich migrate to the site of damage and release growthfactors cytokines and ROSRNS species Chronic inflamma-tion occurs when the acute inflammation is not successfullyresolved This inflammatory condition plays a critical role inthe pathogenesis of many diseases including atherosclerosiscancer asthma Alzheimerrsquos and Parkinsonism [88 89]

Several studies have associated different types of propolisand its various constituents with anti-inflammatory activ-ity [61 90ndash95] Table 3 summarizes the anti-inflammatory

mechanisms investigated with propolis and its chemicalconstituents Recently the role of the flavonoids quercetinflavonols and flavones in modulating inflammatory cellfunction was studied [92] Funakoshi-Tago et al [96] inves-tigated the anti-inflammatory effects of flavonoids isolatedfrom Nepalese PEE on the IL-33 signaling pathway Theisolated flavonoids 3101584041015840-dihydroxy-4-methoxydalbergione4-methoxydalbergion cearoin and chrysin inhibited theexpression of inflammatory genes including IL-6 TNF-120572and IL-13 in bone marrow-derived mast cells (BMMC) andalso inhibited the activation of IKK which leads to thedegradation of I120581B120572 and inhibits the activation of nuclearfactor 120581B (NF-120581B)

The release and oxygenation of arachidonic acid are acritical event in inflammation Mirzoeva and Calder [90]demonstrated that propolis components such as CAPE caf-feic acid quercetin andnaringenin among others inhibit theproduction of eicosanoids In fact these components signif-icantly suppressed the lipoxygenase pathway of arachidonicacid metabolism CAPE being the most potent modulatorAnother study indicated that CAPE treatment improveshepatic steatosis induced by high-fat diet in a mouse modelThis effect was attributed to the reduction of c-Jun-N-terminal kinase (JNK12) andNF-120581B activationwith decreasein COX-2 expression [97] Recently it was reported thatCAPE exhibits inhibitory effects on the production of proin-flammatory cytokines (interleukin-1120573 (IL-1120573)) tumor necro-sis factor-120572 (TNF-120572) and monocyte chemoattractant pro-tein 1 (MCP-1) from lipopolysaccharide- (LPS-) stimulatedRAW2647 macrophages [98] Machado et al [99] showedthat Brazilian green propolis water extracts (PWE) modulatean anti-inflammatory cellular response in the model of LPS-induced pulmonary inflammation by decreasing the numberof macrophages and neutrophils Additionally it induced areduction in the secretion of IL-6 and TNF-120572 and an increasein TGF-120573 and IL-10 Another study showed that Brazilianred PEE promotes a significant decrease in renal macrophageinfiltration in rats with chronic kidney disease [100] Bufaloet al [101] demonstrated that Brazilian PEE and caffeicacid inhibited LPS-induced NO production by RAW2647macrophages acting at the transcriptional level and sug-gesting that their anti-inflammatory effects were mediatedby downregulating NF-120581B p38 MAP kinase and JNK12According to Naito et al [95] topical application of BrazilianPEE is effective in inhibiting carrageenan-induced rat hindpaw edemaThis sample appears to inhibit the chemotaxis ofhuman polymorphonuclear leukocytes (PMNs) which alsocontributes to its anti-inflammatory effects Another studyshowed the topical anti-inflammatory activity of propolisfrom Chile in mice ear with induced-edema In fact PEEfrom Buin Chile was the most active against the inflamma-tion induced by 12-O-tetradeca-noylphorbol-13-acetate andarachidonic acid and also inhibits significantly NO releaseby the macrophages [102] More recently Boudreau et al[103] indicated that CAPE is a potent leukotriene biosynthesisinhibitor in PMNs that blocks 5-lipoxygenase (5-LO) activityand arachidonic acid release A Croatian PEE may improvepsoriatic-like skin lesions whichwere induced in the study byirritant agents like n-hexyl salicylate or di-n-propyl disulfide

by reducing the lipid peroxidation in the skin and totalnumber of inflammatory cells in the skin and peritonealcavity more specially by suppressing functional activity ofmacrophages [104]

43 Immunomodulatory Activity Natural substances areconsidered alternative adjuvant therapies in the treatment ofdifferent diseases due to their immunomodulatory effectsInformation about this type of activity was scarce for propolisuntil the 1990s but published work in the last years has pro-vided information about the influence of different propolissamples on the immune system [65 105ndash112] (Table 4)

In a study using Brazilian green propolis it was seenthat the administration for 3 days of a PEE to male BALBcmice modulated the activation of the initial steps of theimmune response by upregulating toll-like receptor- (TLR-)2 and toll-like receptor-4 expression and proinflammatorycytokines (IL-1 and IL-6) production by macrophages andspleen cells [105] Another study demonstrated that BraziliangreenPEEupregulates TLR-4 andCD80 expression in humanmonocytes as well as TNF-120572 and IL-10 production [113] Itwas also shown that caffeic acid stimulates the activity ofmonocytes againstC albicans but it inhibits TLR-2 andHLA-DR expression as well as TNF-120572 and IL-10 production [114]

Additionally Missima et al [115] showed that Braziliangreen PEE administered to stressed mice reduces the proin-flammatory cytokines IL-1120573 and IL-6 When administered tomelanoma-bearing mice submitted or not to chronic stressit induces high levels of IL-1120573 and IL-6 and also stimu-lates Th1 cytokines production indicating the activation ofantitumour cell-mediated immunity Bachiega et al [116]investigated the immunomodulatory effect of propolis andcinnamic and coumaric acids on cytokines IL-1120573 IL-6 andIL-10 production Peritonealmacrophages fromBALBcmicewere incubated with different concentrations of propolis(5 50 and 100mgwell) and coumaric and cinnamic acid(50 and 100mgwell) Propolis and the acids stimulated IL-1120573 production and significantly inhibited IL-6 productionThen after LPS incubation the inhibitory concentrations ofcinnamic and coumaric acids prevented efficiently its effectson IL-6 production whereas propolis inhibited LPS effectsboth before and after its addition Additionally propolis andcoumaric and cinnamic acids inhibited IL-10 production Astudy which evaluated the effect of Brazilian green propolison macrophage activation by H

2O2and NO metabolite

determination [107] showed that propolis increased H2O2

generation and decreased NO generation which favoursthe microbicidal activity Recently the immunomodulatoryeffect of propolis collected in Brazil was evaluated in Leish-mania (Viannia) braziliensis experimental infection Datashows that macrophages incubated with propolis showed asignificant increase in interiorization and further killing ofparasites Also an increased TNF-120572 production was seen inpropolis-pretreated mice whereas IL-12 was downregulatedduring the infection [117]

The immunomodulatory action of propolis does notoccur only at the macrophage level In fact some studiesshow that this action has also an effect on lymphocyte pro-liferation [106 108] Sa-Nunes et al [108] showed inhibitory

10 Evidence-Based Complementary and Alternative Medicine

effects of Brazilian green propolis on splenocyte proliferationeffect that was attributed to flavonoids and enhancementeffects on interferon- (IFN-) 120574 production by spleen cellsCAPE displays inhibitory effects on transcription factors NF-120581B and NFAT and as a consequence inhibits IL-2 genetranscription IL-2 receptor expression and proliferation ofhuman T cells [94] This provides new information into themolecular mechanisms involved in the anti-inflammatoryand immunomodulatory activities of propolis CAPE hasvarious biological activities but its effect on the immunomod-ulatory activity remains little studied According to Wanget al [112] CAPE can be useful in the treatment of asthmaand other allergic diseases because it can inhibit cytokinesand chemokines production by human monocyte-deriveddendritic cells (MoDCs) which might be related to theNF-120581B signalling pathway Another study demonstrated forthe first time that Brazilian propolis significantly inhibitedthe generation of Th1 cells Furthermore the effects ofpropolis were investigated on 246-trinitrobenzene sulfonicacid- (TNBS-) induced colitis in a mouse model Propolisreduced the frequency of IFN-120574-producing CD4 T cellsin a dose-dependent way under Th1-polarizing conditionsThe inhibitory effect of propolis on Th1 differentiation wasdemonstrated in vivo too and the severity of colitis inpropolis-fed mice was significantly lower than that of micefed with the control diet [118]

44 Antiviral Activity Propolis comprises a complexity ofcompounds which play a role in antiviral protection Despitethe few data available regarding this activity it was shown thatpropolis from different geographic regions has considerableantiviral activity by acting at different levels and interferingwith the replication of some viruses [12] like herpes simplextypes 1 and 2 adenovirus type 2 influenza virus or humanimmunodeficiency virus (HIV) among others [7 60 119ndash124] Table 5 summarizes the antiviral activity of propolis andits chemical constituents

Schnitzler et al [123] analysed the antiviral effect ofPWE and PEE from Czech Republic as well as that ofthe constituents caffeic acid p-coumaric acid benzoic acidgalangin pinocembrin and chrysin against herpes simplexvirus type 1 (HSV-1) in cell culture Both extracts exhibitedhigh anti-HSV-1 activity when cells were treated prior toviral infection galangin and chrysin being the main bioac-tive compounds Amoros et al [60] showed the antiviralactivity of the major flavonoids of propolis more specificallyflavonols and flavones the first being more active againstHSV-1 Additionally they analysed the effect of propolis onseveral DNA and RNA viruses (HSV-1 HSV-2 adenovirustype 2 vesicular stomatitis virus (VSV) and poliovirus type2) Propolis at a concentration of 30120583gmL reduced thetiter of herpes virus however vesicular stomatitis virusand adenovirus were less susceptible In addition propo-lis appears to exert a virucidal action on the envelopedviruses HSV and VSV [120] Recently it was shown thathydromethanolic extract of geopropolis from the stinglessbee Scaptotrigona postica (Brazil) inhibits theHSV replicationand also the entry of the virus into cells effect that wasattributed to the C-glycosyl flavones catechin-3-O-gallate

and 34-dicaffeoylquinic acid [125] According to Tait etal [126] natural and synthetic flavonoids might interferewith picornavirus replication preventing the decapsidationof viral particles and RNA release within cells or blockingviral RNA synthesis These authors also showed that differ-ent homoisoflavonoids have good antiviral activity againstthe coxsackie viruses B3 B4 and A9 and echovirus 30Shvarzbeyn and Huleihel [127] tried to determine whichstep of Tax oncoprotein-induced NF-120581B activation is blockedby propolis and CAPE and showed that both substantiallyinhibited the activation of NF-120581B-dependent promoter byTax Also they strongly prevented both Tax binding to I120581B120572and its induced degradation by Tax Ma et al [128] showedthat nanometer propolis flavones could significantly inhibitin vitro porcine parvovirus (PPV) infecting PK-15 cells andin vivo they restrain the PPV copy in lung gonad and blooddecrease the impact of PPV on weight of guinea pigs andincrease hemagglutination inhibition of PPV in serum as wellas improving the contents of IL-2 IL-6 and 120574-IFN

Over recent years therapeutic benefits of propolis andorits isolated compounds have been described in HIV treat-ment Ito et al [129] tested the anti-HIV activity in H9lymphocytes of triterpenoids melliferone moronic acidanwuweizonic acid and betulonic acid and four knownaromatic compounds isolated from Brazilian propolis andshowed that moronic acid had significant anti-HIV activityGekker et al [119] assessed the anti-HIV-1 activity of propolisin CD4+ lymphocytes and microglial cell cultures observ-ing the inhibition of viral expression in a concentration-dependent wayThe possible mechanism of propolis antiviralproperty was suggested to involve inhibition of viral entry

45 Antimicrobial Activity Antimicrobial activity one ofthe most studied propolis biological properties is very welldocumented This bioactivity has been largely investigatedin the last years due to the need of new treatments againstinfectious diseases especially with the increase of resistantpathogens to current antibiotics Tables 6 and 7 summarisethe antibacterial and antifungal activities found in propolisfrom different geographic origin andor its chemical con-stituents

451 Antibacterial Activity Propolis effect against severalbacterial strains has evaluated [7 56ndash59 130] and supportedthe fact that propolis is more active against Gram-positivebacteria than Gram-negative bacteria [12 59] Briefly datafrom different studies showed that propolis inhibits bac-terial motility and enzyme activity exhibits bacteriostaticactivity against different bacterial genera can be bactericidalin high concentrations and affects cytoplasmic membrane[130]

Mirzoeva et al [130] investigated the effect of PEEon the physiology of Bacillus subtilis Escherichia coli andRhodobacter sphaeroides proposing that propolis and someof its components like cinnamic acid and flavonoids affectthe ion permeability of the inner bacterial membrane causingthe dissipation of the membrane potential and inhibitingbacterial motility A recent study [131] provided valuableinformation for understanding the potential anti-H pylori

mechanism of CAPE H pylori a major factor for gas-trointestinal illnesses contains the enzyme H pylori peptidedeformylase that catalyses the removal of formyl group fromthe N-terminus of nascent polypeptide chains Since theaction of this enzyme is essential for H pylori survival it isconsidered a promising therapeutic drug target Results fromabsorption spectra and crystal structural characterizationshowed that CAPE is a competitive inhibitor of peptidedeformylase blocking the substrate entrance and preventingsubstrate from approaching the active site [131]

It has been suggested that the combination of propoliswith other antibiotics would allow dose reduction of selectedantibiotics thus potentiating their effect The antibacterialactivity of Italian PEE in some clinically isolated Gram-positive strains as well as the synergetic effect with someantibiotics was assessed by Scazzocchio et al [56] Ital-ian PEE drastically increased the effect of ampicillin gen-tamycin and streptomycin and moderated the action ofchloramphenicol ceftriaxone and vancomycin No effectwas observed when used simultaneously with erythromycinWojtyczka et al [132] evaluated the in vitro antimicrobialactivity of a Polish PEE against methicillin-sensitive S aureus(MSSA) and methicillin-resistant S aureus (MRSA) clinicalisolates and also the combined effect of propolis with tenselected antistaphylococcal drugs PEE displayed varyingeffectiveness against twelve S aureus strains and potentiatedthe antimicrobial effect of eight antistaphylococcal againstall tested strains No synergism was observed in the caseof ciprofloxacin and chloramphenicol In another study theeffect of dichloromethane extract of French propolis againstdifferent human pathogenic bacterial strains was also testedAlthough Gram-negative bacteria were not susceptible tothe extract a significant antibacterial activity against bothmethicillin-resistant and methicillin-susceptible S aureusstrains was observed [133] The same was confirmed byVelikova et al [28] using different PEE from BulgariaGreece Turkey and Algeria All the samples showed agood antibacterial activity against S aureus but a week orlacking effect against E coli Australian PEE from stinglessbee Tetragonula carbonaria also inhibited the growth of Saureus Nevertheless it was less active against P aeruginosa[42] The same was observed by Papachroni et al [53]using PEE from Cameroon and CongoContrary to thesestudies Katircioglu and Mercan [134] showed that TurkishPEE was effective against Gram-negative bacteria like E coliOrsi et al [135] investigated the possible synergism betweenBrazilian and Bulgarian propolis and antibiotics acting onDNA (ciprofloxacin and norfloxacin) and on metabolism(cotrimoxazole) in Salmonella typhi Both samples hadantibacterial activity but no synergistic effect was detected

Recently the suitability of nanohydroxyapatite- (nano-HA-) based surfaces containing two Brazilian PEE (greenand red ones) to prevent S aureus bacterial growth andbiofilm was studied The nanoHA impregnated with thetwo highest concentrations (12 and 25120583gmL) of red PEEshowed a remarkable reduction of 99 in the number ofviable bacteria while nanoHA with green PEE at sameconcentrations showed a reduction of 45 and 61 Moreoverthe nanoHA impregnated with the highest concentration of

red PEE was able to inhibit 80 of the staphylococcal biofilmformation [136]

Diverse studies show that as the composition of propolisvaries from region to region the antibacterial activity alsodisplays some variations [59] Susceptibility of differentGram-positive bacteria to PEE varies with the place ofpropolis collection [137] The antibacterial effect was shownto be higher for samples from a wet-tropical rain forest-type climate Other studies revealed the influence of propolisgeographical origin on its antibacterial properties [57 58 138139] Propolis from the north and centre of Portugal has agreat activity against S aureus [58 140]

452 Antifungal Activity Antifungal activity is also influ-enced by the chemical variation of propolis [59] Severalstudies have shown the effect of propolis from differentgeographic origin against different fungi particularly ofclinical interest [141ndash145] Quiroga et al [146] demonstratedthe antifungal activity of propolis from the northwest ofArgentina focusing their study on the environment andthe development of agrochemicals with reduced economiccosts possibly containing propolis extracts and its isolatedcompounds such as pinocembrin and galangin as activeprinciples

Recently Falcao et al [140] screened the antifungalactivity of Portuguese propolis and its potential floral sourcesPopulus x Canadensis and Cistus ladanifer against Candidaalbicans Trichophyton rubrum and Aspergillus fumigatusPlant extracts did not exhibit relevant antifungal activity withexception of T rubrum but both propolis samples revealedsimilar antifungal activity the highest being obtained againstT rubrum and the lowest against A fumigatus A sample ofPEE from Poland showed a high fungicidal activity againstC albicans C glabrata and C krusei [147] Recently it wasshown that different organic extracts of French propolis (PEEPWEmethanolic extract and dichloromethane extract) wereeffective against C albicans and C glabrata but only have aweak activity towards A fumigates [133]

Brazilian PEE was proved to be active against severalCandida strains (C albicans C tropicalis C krusei andC guilliermondii) C albicans being the most sensitive andC guilliermondii the most resistant [141] Brazilian greenand red propolis display activity against different fungalspecies of Trichophyton which cause dermatophytosis redPEE being more efficient than the green one [143] Also itwas shown that n-hexane extract of Brazilian red propolisdid not induce resistance in Candida spp In fact it wasactive against Candida spp resistant to antifungal agentslike fluconazole [148] Dota et al [144] evaluated the in vitroantifungal activity of PEE and propolis microparticles (PMs)obtained from a sample from Argentina against clinical yeastisolates of importance in the vulvovaginal candidiasis Calbicans and non-C albicanswere inhibited by PEE and PMswith small variation Additionally it was shown that Braziliangreen PEE has the ability to inhibit growth and biofilmformation by C albicans from vulvovaginal candidiasis [149]Another study showed fungicide action of propolis (PEEPWE propolis matricial microparticles (PMM) and propolissoluble dry extract after 6ndash8-hour treatment against all three

C albicansmorphotypes (yeast pseudohyphae and hyphae)PEE being the most potent followed by PSDE PM andPWE [150] Brazilian propolis induces C albicans cell deathmediated via metacaspase since the metacaspase mutant inC albicans showed reduced sensitivity to propolis and bythe Ras pathway Using C albicans deletion libraries it waspossible to screen several mutants in genes involved eitherin the morphological transitions or in the maintenance of aspecific morphotype that are more sensitive to propolis Toconclude the study the authors also showed that propolisbased gels and cream were partially able to control vulvo-vaginal candidiasis in a mouse model [151] These studies[144] strongly indicate that propolis has a great potential tocontrol vulvovaginal candidiasis representing a promisingalternative therapeutic strategy

46 Antitumour Activity Recognition of the hallmarks ofcancer affects the search and development of new meth-ods and therapeutic agents with a sufficiently large thera-peutic window to kill tumour cells while sparing normalcells In the last years the natural product propolis hasattracted a growing interest by a large number of researcherssince it contains a variety of phytochemical compoundsthat may act through multiple pathways to reduce thedevelopment and other malignant characteristics of cancercells

Recently several in vitro studies have demonstrated acytotoxic action of propolis from different geographic originand of some of its isolated compounds on various tumourcells In vivo studies also show a potential in the developmentof new antitumor agents since propolis administration tomammals (eg rats) does not lead to detectable side effects[3] Briefly this natural product can block specific oncogenesignalling pathways which in turn lead to a decrease in cellproliferation and growth and can also act by decreasing thecancer stem cell population increasing apoptosis exertingantiangiogenic effects and modulating the tumour microen-vironment [66 152 153] Table 8 summarizes the antitumouractivity of propolis from different geographic origin and itschemical constituents

Some researchers showed the effect of different types ofpropolis and its constituents on cancer cell growth prolifera-tion and apoptosisThe hexane extract of propolis fromThai-land collected by the stingless bee Trigona laeviceps whichhas a different behavior in propolis collection compared tothe honey bees exerts antiproliferative activity against fivetested cancer cell lines (Chago KATO-III SW620 BT474and Hep-G2) but not against the normal cell lines tested(HS27 fibroblast and CH-liver) [5] A sample of PEE fromPoland inhibited human malignant melanoma (Me45) andcolorectal cancer (HCT 116) cells growth as well as reducedcell size [154]Other studies reported the antitumor activity ofBrazilianPEE [155ndash158]which regulate the protein expressionof cyclin D1 B1 and cyclin dependent kinase (CDK) as wellas p21 in human prostate cancer cells significantly affectingproliferation [158]

Although propolis containing CAPE is different fromthose with artepillin C it is possible to obtain a similarinhibitory effect from both types The effect of CAPE on

different cancer cell lines was analysed and many of itseffects have been shown to be mediated through inhibitionof NF-120581B [66 159] CAPE can inhibit the proliferation of thecolorectal cell line SW480 by decreasing the 120573-catenin c-myc and cyclin D1 protein expression [160] Chuu et al [161]observed that CAPE suppressed the proliferation of LNCaPDU-145 and PC-3 human prostate cancer cells in a dose-dependent manner and also inhibited the tumour growthof LNCaP xenografts in nude mice It was suggested that itacted through inhibition of p70S6K (an intermediary of thePI3KAKTpathway responsible for the protein synthesis) andsome Akt signalling networks Wu et al [162] demonstratedthat CAPE inhibits in vitro and in vivoMCF-7 andMDA-MB-231 tumour growthwithoutmuch effect on normalmammarycells by reducing the expression of growth and transcriptionfactors including NF-120581B Recently it was demonstrated thatCAPE effect on genes that are associated with tumour cellgrowth and survival is related in part to its role as a histonedeacetylase inhibitor [163]

As previously said propolis can also act by decreasingthe cancer stem cell population Using the putative CD44(+)CD24 (minuslow) breast cancer stem cells able to generatemammospheres from single cells Omene et al [164] showedthat CAPE caused a dose-dependent inhibition of cancerstem cells self-renewal progenitor formation and clonalgrowth

Concerning cell death some in vitro studies showeddifferent sensitivities of tumour cells to propolis extractsPWE from Iraq inhibits the proliferation of HL-60 cellsand leads to downregulation of Bcl-2 and activation of Bax[13] Alizadeh et al [165] investigated the protective effectsof Iranian PEE on N-methyl-N-nitro-N-nitrosoguanidine-(MNNG-) initiated gastric cancer in rats Results showedthat tumour incidence the number of lesions structuralabnormalities and beta-catenin of the animals group treatedwith PEE significantly declined compared with the controlPEE also induced the expression of proapoptotic Bax andreduced antiapoptotic Bcl-2 expression Propolis inhibitscolony formation potential and promotes necrotic changes inHCT-116 cells and decreases mitotic cells and increases p53and Ki-67 expression in HCT-116 tumor-bearing mice [13]Szliszkarsquos group have performed many studies to analyze theantitumour effect of different propolis and its constituentson prostate cancer cells (LNCaP and DU145) [166ndash168]Brazilian green PEE sensitized these cells to TRAIL-induceddeath enhanced the expression of TRAIL-R2 and decreasedthe activity of NF-120581B in LNCaP cells [167] Cotreatment ofTRAIL with artepillin C induced the significant activation ofcaspase-8 and caspase-3 as well as a significant disruption ofthe mitochondrial membrane potential [169] Many studieshave been conducted to understand the pathways involvedin the apoptotic effect of CAPE CAPE induces cell cyclearrest and apoptosis and reduces expression of NF-120581B inMDA-MB-231 and MCF-7 human breast cancer cells [162]In PC3 prostate cancer cells CAPE induced apoptosis in adose-dependent manner that was associated with the loss ofexpression of the inhibitors of apoptosis cIAP-1 cIAP-2 andXIAP [170] Cavaliere et al [171] showed that CAPE treatment

of lymphoblastoid cell line PL104 induced apoptosis throughthe mitochondrial intrinsic pathway

It has been known that cancer microenvironment isvery important for carcinogenesis and it consists of stromalendothelial immune and cancer cells Natural productslike propolis and their constituents have been shown tointerfere with this symbiosis It was demonstrated by Lee et al[172] that CAPE could effectively suppress the adhesion andinvasion potential of human hepatocellular carcinoma cells(SK-Hep1) by inhibiting the expression ofMMP-2 andMMP-9 and NF-120581B

Angiogenesis has a crucial role in tumour growth dueto the requirement of oxygen and nutrients to sustain rapiduncontrolled proliferation and metastization Both tumourand stromal cells can secrete proangiogenic factors thatstimulate the formation andmaintenance of new vessels suchas vascular endothelial growth factor (VEGF) [173] BrazilianPEE could significantly reduce the number of newly formedvessels and suppress the proliferation of human umbilicalvein endothelial cells (HUVECs) [174] this antiangiogeniceffect being mainly mediated via inducing apoptosis in tube-forming endothelial cells through the inactivation of the sur-vival signal ERK12 [175] Yun et al [176] observed that CAPEinhibited angiogenesis using the in vivo assay chick embryochorioallantoic membrane (CAM) CAPE also suppressesVEGF formation by MDA-MB-231 cells and formation ofcapillary-like tubes by endothelial cells [162 177] Extractsof propolis containing artepillin C and CAPE significantlyreduced the newly formed vessels and expression of MMPsand VEGF production from various cells [178] and inaccordance with this study Izuta et al [179] described thatCAPE promotes inhibition of VEGF expression in HUVECcells

The first study on the antitumor activity of Portuguesepropolis was only performed in 2010 Using normal andcancerous renal cells derived from human renal cell carci-noma (RCC) patients in addition to A-498 cell line Valenteet al [64] showed that methanolic extract of Portuguesepropolis exhibited selective toxicity against malignant cellscompared to normal cells and in vitro RCC growth wasstrongly inhibited Recently our group demonstrated theantitumour and antiangiogenic activity of the ethanol extractof Pereiro propolis (P10EE) collected in the district ofGuarda Portugal P10EE affects cell viability of differenttumour cells MDA-MB-231 (breast) and DU145 (prostate)being two of the most sensitive ones but was less cytotoxicagainst nontumour cells and fibroblasts Also it signifi-cantly decreased MDA-MB-231 and DU145 cell prolifera-tion and migration along time with cell cycle changesand increased cell death The significant increase observedin glucose consumption and lactate production could beexplained in MDA-MB-231 by an increased expression ofhypoxia inducible factor-1120572 pyruvate dehydrogenase kinaseglucose transporter 1 lactate dehydrogenase and carbonicanhydrase Furthermore P10EE induced a decrease inHBMECs total biomass and proliferation and decreasedvessel sprouting in the chicken chorioallantoic membrane[23]

5 Conclusions

From ancient to modern times herbs and other plant prod-ucts have been widely used as medicinal agents first in folkmedicine and other activities in many parts of the world andlater developed and improved on a scientific basis into drugsthat are used in the health system Propolis is one of thefew natural products that has maintained its popularity overa long period of time As reviewed here propolis containsa broad spectrum of compounds that may be useful in thetreatment of different pathological conditions In fact there ismuch literature that deals with the in vitro and in vivo biologi-cal properties of propolisThis wide range of bioactivities thecontinuous discovery of new compounds the long history ofpropolis use and its safety profile make propolis a potentialcandidate for drug discovery that may be useful in severalclinical scenarios Nevertheless it is necessary to make aneffort to standardize propolis composition since it seems thatpropolis biological properties and chemical composition notonly are variable but also are strictly linked In our opinionpropolis extracts may be important economically and wouldallow a relatively inexpensive treatment in different diseaseshowever to promote its use in modern medicine it will benecessary to identify and isolate the bioactive compoundsto be tested separately or in combination with other drugsalready available

Drug discovery does not consist only of the isolationof bioactive lead compounds from the natural sources Infact this process continues outside the academic laboratoriesthrough preclinical studies followed by clinical trials Thusdespite the in vitro and in vivo assays which provide newvaluable information on propolis biological properties andmechanisms of action it will be necessary to analyse theeffectiveness of propolis clinically to complement the basicresearch available and to evaluate the potential of propolis inhuman health promotion

mechanisms investigated with propolis and its chemicalconstituents Recently the role of the flavonoids quercetinflavonols and flavones in modulating inflammatory cellfunction was studied [92] Funakoshi-Tago et al [96] inves-tigated the anti-inflammatory effects of flavonoids isolatedfrom Nepalese PEE on the IL-33 signaling pathway Theisolated flavonoids 3101584041015840-dihydroxy-4-methoxydalbergione4-methoxydalbergion cearoin and chrysin inhibited theexpression of inflammatory genes including IL-6 TNF-120572and IL-13 in bone marrow-derived mast cells (BMMC) andalso inhibited the activation of IKK which leads to thedegradation of I120581B120572 and inhibits the activation of nuclearfactor 120581B (NF-120581B)

The release and oxygenation of arachidonic acid are acritical event in inflammation Mirzoeva and Calder [90]demonstrated that propolis components such as CAPE caf-feic acid quercetin andnaringenin among others inhibit theproduction of eicosanoids In fact these components signif-icantly suppressed the lipoxygenase pathway of arachidonicacid metabolism CAPE being the most potent modulatorAnother study indicated that CAPE treatment improveshepatic steatosis induced by high-fat diet in a mouse modelThis effect was attributed to the reduction of c-Jun-N-terminal kinase (JNK12) andNF-120581B activationwith decreasein COX-2 expression [97] Recently it was reported thatCAPE exhibits inhibitory effects on the production of proin-flammatory cytokines (interleukin-1120573 (IL-1120573)) tumor necro-sis factor-120572 (TNF-120572) and monocyte chemoattractant pro-tein 1 (MCP-1) from lipopolysaccharide- (LPS-) stimulatedRAW2647 macrophages [98] Machado et al [99] showedthat Brazilian green propolis water extracts (PWE) modulatean anti-inflammatory cellular response in the model of LPS-induced pulmonary inflammation by decreasing the numberof macrophages and neutrophils Additionally it induced areduction in the secretion of IL-6 and TNF-120572 and an increasein TGF-120573 and IL-10 Another study showed that Brazilianred PEE promotes a significant decrease in renal macrophageinfiltration in rats with chronic kidney disease [100] Bufaloet al [101] demonstrated that Brazilian PEE and caffeicacid inhibited LPS-induced NO production by RAW2647macrophages acting at the transcriptional level and sug-gesting that their anti-inflammatory effects were mediatedby downregulating NF-120581B p38 MAP kinase and JNK12According to Naito et al [95] topical application of BrazilianPEE is effective in inhibiting carrageenan-induced rat hindpaw edemaThis sample appears to inhibit the chemotaxis ofhuman polymorphonuclear leukocytes (PMNs) which alsocontributes to its anti-inflammatory effects Another studyshowed the topical anti-inflammatory activity of propolisfrom Chile in mice ear with induced-edema In fact PEEfrom Buin Chile was the most active against the inflamma-tion induced by 12-O-tetradeca-noylphorbol-13-acetate andarachidonic acid and also inhibits significantly NO releaseby the macrophages [102] More recently Boudreau et al[103] indicated that CAPE is a potent leukotriene biosynthesisinhibitor in PMNs that blocks 5-lipoxygenase (5-LO) activityand arachidonic acid release A Croatian PEE may improvepsoriatic-like skin lesions whichwere induced in the study byirritant agents like n-hexyl salicylate or di-n-propyl disulfide

by reducing the lipid peroxidation in the skin and totalnumber of inflammatory cells in the skin and peritonealcavity more specially by suppressing functional activity ofmacrophages [104]

43 Immunomodulatory Activity Natural substances areconsidered alternative adjuvant therapies in the treatment ofdifferent diseases due to their immunomodulatory effectsInformation about this type of activity was scarce for propolisuntil the 1990s but published work in the last years has pro-vided information about the influence of different propolissamples on the immune system [65 105ndash112] (Table 4)

In a study using Brazilian green propolis it was seenthat the administration for 3 days of a PEE to male BALBcmice modulated the activation of the initial steps of theimmune response by upregulating toll-like receptor- (TLR-)2 and toll-like receptor-4 expression and proinflammatorycytokines (IL-1 and IL-6) production by macrophages andspleen cells [105] Another study demonstrated that BraziliangreenPEEupregulates TLR-4 andCD80 expression in humanmonocytes as well as TNF-120572 and IL-10 production [113] Itwas also shown that caffeic acid stimulates the activity ofmonocytes againstC albicans but it inhibits TLR-2 andHLA-DR expression as well as TNF-120572 and IL-10 production [114]

Additionally Missima et al [115] showed that Braziliangreen PEE administered to stressed mice reduces the proin-flammatory cytokines IL-1120573 and IL-6 When administered tomelanoma-bearing mice submitted or not to chronic stressit induces high levels of IL-1120573 and IL-6 and also stimu-lates Th1 cytokines production indicating the activation ofantitumour cell-mediated immunity Bachiega et al [116]investigated the immunomodulatory effect of propolis andcinnamic and coumaric acids on cytokines IL-1120573 IL-6 andIL-10 production Peritonealmacrophages fromBALBcmicewere incubated with different concentrations of propolis(5 50 and 100mgwell) and coumaric and cinnamic acid(50 and 100mgwell) Propolis and the acids stimulated IL-1120573 production and significantly inhibited IL-6 productionThen after LPS incubation the inhibitory concentrations ofcinnamic and coumaric acids prevented efficiently its effectson IL-6 production whereas propolis inhibited LPS effectsboth before and after its addition Additionally propolis andcoumaric and cinnamic acids inhibited IL-10 production Astudy which evaluated the effect of Brazilian green propolison macrophage activation by H

2O2and NO metabolite

determination [107] showed that propolis increased H2O2

generation and decreased NO generation which favoursthe microbicidal activity Recently the immunomodulatoryeffect of propolis collected in Brazil was evaluated in Leish-mania (Viannia) braziliensis experimental infection Datashows that macrophages incubated with propolis showed asignificant increase in interiorization and further killing ofparasites Also an increased TNF-120572 production was seen inpropolis-pretreated mice whereas IL-12 was downregulatedduring the infection [117]

The immunomodulatory action of propolis does notoccur only at the macrophage level In fact some studiesshow that this action has also an effect on lymphocyte pro-liferation [106 108] Sa-Nunes et al [108] showed inhibitory

10 Evidence-Based Complementary and Alternative Medicine

effects of Brazilian green propolis on splenocyte proliferationeffect that was attributed to flavonoids and enhancementeffects on interferon- (IFN-) 120574 production by spleen cellsCAPE displays inhibitory effects on transcription factors NF-120581B and NFAT and as a consequence inhibits IL-2 genetranscription IL-2 receptor expression and proliferation ofhuman T cells [94] This provides new information into themolecular mechanisms involved in the anti-inflammatoryand immunomodulatory activities of propolis CAPE hasvarious biological activities but its effect on the immunomod-ulatory activity remains little studied According to Wanget al [112] CAPE can be useful in the treatment of asthmaand other allergic diseases because it can inhibit cytokinesand chemokines production by human monocyte-deriveddendritic cells (MoDCs) which might be related to theNF-120581B signalling pathway Another study demonstrated forthe first time that Brazilian propolis significantly inhibitedthe generation of Th1 cells Furthermore the effects ofpropolis were investigated on 246-trinitrobenzene sulfonicacid- (TNBS-) induced colitis in a mouse model Propolisreduced the frequency of IFN-120574-producing CD4 T cellsin a dose-dependent way under Th1-polarizing conditionsThe inhibitory effect of propolis on Th1 differentiation wasdemonstrated in vivo too and the severity of colitis inpropolis-fed mice was significantly lower than that of micefed with the control diet [118]

44 Antiviral Activity Propolis comprises a complexity ofcompounds which play a role in antiviral protection Despitethe few data available regarding this activity it was shown thatpropolis from different geographic regions has considerableantiviral activity by acting at different levels and interferingwith the replication of some viruses [12] like herpes simplextypes 1 and 2 adenovirus type 2 influenza virus or humanimmunodeficiency virus (HIV) among others [7 60 119ndash124] Table 5 summarizes the antiviral activity of propolis andits chemical constituents

Schnitzler et al [123] analysed the antiviral effect ofPWE and PEE from Czech Republic as well as that ofthe constituents caffeic acid p-coumaric acid benzoic acidgalangin pinocembrin and chrysin against herpes simplexvirus type 1 (HSV-1) in cell culture Both extracts exhibitedhigh anti-HSV-1 activity when cells were treated prior toviral infection galangin and chrysin being the main bioac-tive compounds Amoros et al [60] showed the antiviralactivity of the major flavonoids of propolis more specificallyflavonols and flavones the first being more active againstHSV-1 Additionally they analysed the effect of propolis onseveral DNA and RNA viruses (HSV-1 HSV-2 adenovirustype 2 vesicular stomatitis virus (VSV) and poliovirus type2) Propolis at a concentration of 30120583gmL reduced thetiter of herpes virus however vesicular stomatitis virusand adenovirus were less susceptible In addition propo-lis appears to exert a virucidal action on the envelopedviruses HSV and VSV [120] Recently it was shown thathydromethanolic extract of geopropolis from the stinglessbee Scaptotrigona postica (Brazil) inhibits theHSV replicationand also the entry of the virus into cells effect that wasattributed to the C-glycosyl flavones catechin-3-O-gallate

and 34-dicaffeoylquinic acid [125] According to Tait etal [126] natural and synthetic flavonoids might interferewith picornavirus replication preventing the decapsidationof viral particles and RNA release within cells or blockingviral RNA synthesis These authors also showed that differ-ent homoisoflavonoids have good antiviral activity againstthe coxsackie viruses B3 B4 and A9 and echovirus 30Shvarzbeyn and Huleihel [127] tried to determine whichstep of Tax oncoprotein-induced NF-120581B activation is blockedby propolis and CAPE and showed that both substantiallyinhibited the activation of NF-120581B-dependent promoter byTax Also they strongly prevented both Tax binding to I120581B120572and its induced degradation by Tax Ma et al [128] showedthat nanometer propolis flavones could significantly inhibitin vitro porcine parvovirus (PPV) infecting PK-15 cells andin vivo they restrain the PPV copy in lung gonad and blooddecrease the impact of PPV on weight of guinea pigs andincrease hemagglutination inhibition of PPV in serum as wellas improving the contents of IL-2 IL-6 and 120574-IFN

Over recent years therapeutic benefits of propolis andorits isolated compounds have been described in HIV treat-ment Ito et al [129] tested the anti-HIV activity in H9lymphocytes of triterpenoids melliferone moronic acidanwuweizonic acid and betulonic acid and four knownaromatic compounds isolated from Brazilian propolis andshowed that moronic acid had significant anti-HIV activityGekker et al [119] assessed the anti-HIV-1 activity of propolisin CD4+ lymphocytes and microglial cell cultures observ-ing the inhibition of viral expression in a concentration-dependent wayThe possible mechanism of propolis antiviralproperty was suggested to involve inhibition of viral entry

45 Antimicrobial Activity Antimicrobial activity one ofthe most studied propolis biological properties is very welldocumented This bioactivity has been largely investigatedin the last years due to the need of new treatments againstinfectious diseases especially with the increase of resistantpathogens to current antibiotics Tables 6 and 7 summarisethe antibacterial and antifungal activities found in propolisfrom different geographic origin andor its chemical con-stituents

451 Antibacterial Activity Propolis effect against severalbacterial strains has evaluated [7 56ndash59 130] and supportedthe fact that propolis is more active against Gram-positivebacteria than Gram-negative bacteria [12 59] Briefly datafrom different studies showed that propolis inhibits bac-terial motility and enzyme activity exhibits bacteriostaticactivity against different bacterial genera can be bactericidalin high concentrations and affects cytoplasmic membrane[130]

Mirzoeva et al [130] investigated the effect of PEEon the physiology of Bacillus subtilis Escherichia coli andRhodobacter sphaeroides proposing that propolis and someof its components like cinnamic acid and flavonoids affectthe ion permeability of the inner bacterial membrane causingthe dissipation of the membrane potential and inhibitingbacterial motility A recent study [131] provided valuableinformation for understanding the potential anti-H pylori

mechanism of CAPE H pylori a major factor for gas-trointestinal illnesses contains the enzyme H pylori peptidedeformylase that catalyses the removal of formyl group fromthe N-terminus of nascent polypeptide chains Since theaction of this enzyme is essential for H pylori survival it isconsidered a promising therapeutic drug target Results fromabsorption spectra and crystal structural characterizationshowed that CAPE is a competitive inhibitor of peptidedeformylase blocking the substrate entrance and preventingsubstrate from approaching the active site [131]

It has been suggested that the combination of propoliswith other antibiotics would allow dose reduction of selectedantibiotics thus potentiating their effect The antibacterialactivity of Italian PEE in some clinically isolated Gram-positive strains as well as the synergetic effect with someantibiotics was assessed by Scazzocchio et al [56] Ital-ian PEE drastically increased the effect of ampicillin gen-tamycin and streptomycin and moderated the action ofchloramphenicol ceftriaxone and vancomycin No effectwas observed when used simultaneously with erythromycinWojtyczka et al [132] evaluated the in vitro antimicrobialactivity of a Polish PEE against methicillin-sensitive S aureus(MSSA) and methicillin-resistant S aureus (MRSA) clinicalisolates and also the combined effect of propolis with tenselected antistaphylococcal drugs PEE displayed varyingeffectiveness against twelve S aureus strains and potentiatedthe antimicrobial effect of eight antistaphylococcal againstall tested strains No synergism was observed in the caseof ciprofloxacin and chloramphenicol In another study theeffect of dichloromethane extract of French propolis againstdifferent human pathogenic bacterial strains was also testedAlthough Gram-negative bacteria were not susceptible tothe extract a significant antibacterial activity against bothmethicillin-resistant and methicillin-susceptible S aureusstrains was observed [133] The same was confirmed byVelikova et al [28] using different PEE from BulgariaGreece Turkey and Algeria All the samples showed agood antibacterial activity against S aureus but a week orlacking effect against E coli Australian PEE from stinglessbee Tetragonula carbonaria also inhibited the growth of Saureus Nevertheless it was less active against P aeruginosa[42] The same was observed by Papachroni et al [53]using PEE from Cameroon and CongoContrary to thesestudies Katircioglu and Mercan [134] showed that TurkishPEE was effective against Gram-negative bacteria like E coliOrsi et al [135] investigated the possible synergism betweenBrazilian and Bulgarian propolis and antibiotics acting onDNA (ciprofloxacin and norfloxacin) and on metabolism(cotrimoxazole) in Salmonella typhi Both samples hadantibacterial activity but no synergistic effect was detected

Recently the suitability of nanohydroxyapatite- (nano-HA-) based surfaces containing two Brazilian PEE (greenand red ones) to prevent S aureus bacterial growth andbiofilm was studied The nanoHA impregnated with thetwo highest concentrations (12 and 25120583gmL) of red PEEshowed a remarkable reduction of 99 in the number ofviable bacteria while nanoHA with green PEE at sameconcentrations showed a reduction of 45 and 61 Moreoverthe nanoHA impregnated with the highest concentration of

red PEE was able to inhibit 80 of the staphylococcal biofilmformation [136]

Diverse studies show that as the composition of propolisvaries from region to region the antibacterial activity alsodisplays some variations [59] Susceptibility of differentGram-positive bacteria to PEE varies with the place ofpropolis collection [137] The antibacterial effect was shownto be higher for samples from a wet-tropical rain forest-type climate Other studies revealed the influence of propolisgeographical origin on its antibacterial properties [57 58 138139] Propolis from the north and centre of Portugal has agreat activity against S aureus [58 140]

452 Antifungal Activity Antifungal activity is also influ-enced by the chemical variation of propolis [59] Severalstudies have shown the effect of propolis from differentgeographic origin against different fungi particularly ofclinical interest [141ndash145] Quiroga et al [146] demonstratedthe antifungal activity of propolis from the northwest ofArgentina focusing their study on the environment andthe development of agrochemicals with reduced economiccosts possibly containing propolis extracts and its isolatedcompounds such as pinocembrin and galangin as activeprinciples

Recently Falcao et al [140] screened the antifungalactivity of Portuguese propolis and its potential floral sourcesPopulus x Canadensis and Cistus ladanifer against Candidaalbicans Trichophyton rubrum and Aspergillus fumigatusPlant extracts did not exhibit relevant antifungal activity withexception of T rubrum but both propolis samples revealedsimilar antifungal activity the highest being obtained againstT rubrum and the lowest against A fumigatus A sample ofPEE from Poland showed a high fungicidal activity againstC albicans C glabrata and C krusei [147] Recently it wasshown that different organic extracts of French propolis (PEEPWEmethanolic extract and dichloromethane extract) wereeffective against C albicans and C glabrata but only have aweak activity towards A fumigates [133]

Brazilian PEE was proved to be active against severalCandida strains (C albicans C tropicalis C krusei andC guilliermondii) C albicans being the most sensitive andC guilliermondii the most resistant [141] Brazilian greenand red propolis display activity against different fungalspecies of Trichophyton which cause dermatophytosis redPEE being more efficient than the green one [143] Also itwas shown that n-hexane extract of Brazilian red propolisdid not induce resistance in Candida spp In fact it wasactive against Candida spp resistant to antifungal agentslike fluconazole [148] Dota et al [144] evaluated the in vitroantifungal activity of PEE and propolis microparticles (PMs)obtained from a sample from Argentina against clinical yeastisolates of importance in the vulvovaginal candidiasis Calbicans and non-C albicanswere inhibited by PEE and PMswith small variation Additionally it was shown that Braziliangreen PEE has the ability to inhibit growth and biofilmformation by C albicans from vulvovaginal candidiasis [149]Another study showed fungicide action of propolis (PEEPWE propolis matricial microparticles (PMM) and propolissoluble dry extract after 6ndash8-hour treatment against all three

Evidence-Based Complementary and Alternative Medicine 17

C albicansmorphotypes (yeast pseudohyphae and hyphae)PEE being the most potent followed by PSDE PM andPWE [150] Brazilian propolis induces C albicans cell deathmediated via metacaspase since the metacaspase mutant inC albicans showed reduced sensitivity to propolis and bythe Ras pathway Using C albicans deletion libraries it waspossible to screen several mutants in genes involved eitherin the morphological transitions or in the maintenance of aspecific morphotype that are more sensitive to propolis Toconclude the study the authors also showed that propolisbased gels and cream were partially able to control vulvo-vaginal candidiasis in a mouse model [151] These studies[144] strongly indicate that propolis has a great potential tocontrol vulvovaginal candidiasis representing a promisingalternative therapeutic strategy

46 Antitumour Activity Recognition of the hallmarks ofcancer affects the search and development of new meth-ods and therapeutic agents with a sufficiently large thera-peutic window to kill tumour cells while sparing normalcells In the last years the natural product propolis hasattracted a growing interest by a large number of researcherssince it contains a variety of phytochemical compoundsthat may act through multiple pathways to reduce thedevelopment and other malignant characteristics of cancercells

Recently several in vitro studies have demonstrated acytotoxic action of propolis from different geographic originand of some of its isolated compounds on various tumourcells In vivo studies also show a potential in the developmentof new antitumor agents since propolis administration tomammals (eg rats) does not lead to detectable side effects[3] Briefly this natural product can block specific oncogenesignalling pathways which in turn lead to a decrease in cellproliferation and growth and can also act by decreasing thecancer stem cell population increasing apoptosis exertingantiangiogenic effects and modulating the tumour microen-vironment [66 152 153] Table 8 summarizes the antitumouractivity of propolis from different geographic origin and itschemical constituents

Some researchers showed the effect of different types ofpropolis and its constituents on cancer cell growth prolifera-tion and apoptosisThe hexane extract of propolis fromThai-land collected by the stingless bee Trigona laeviceps whichhas a different behavior in propolis collection compared tothe honey bees exerts antiproliferative activity against fivetested cancer cell lines (Chago KATO-III SW620 BT474and Hep-G2) but not against the normal cell lines tested(HS27 fibroblast and CH-liver) [5] A sample of PEE fromPoland inhibited human malignant melanoma (Me45) andcolorectal cancer (HCT 116) cells growth as well as reducedcell size [154]Other studies reported the antitumor activity ofBrazilianPEE [155ndash158]which regulate the protein expressionof cyclin D1 B1 and cyclin dependent kinase (CDK) as wellas p21 in human prostate cancer cells significantly affectingproliferation [158]

Although propolis containing CAPE is different fromthose with artepillin C it is possible to obtain a similarinhibitory effect from both types The effect of CAPE on

different cancer cell lines was analysed and many of itseffects have been shown to be mediated through inhibitionof NF-120581B [66 159] CAPE can inhibit the proliferation of thecolorectal cell line SW480 by decreasing the 120573-catenin c-myc and cyclin D1 protein expression [160] Chuu et al [161]observed that CAPE suppressed the proliferation of LNCaPDU-145 and PC-3 human prostate cancer cells in a dose-dependent manner and also inhibited the tumour growthof LNCaP xenografts in nude mice It was suggested that itacted through inhibition of p70S6K (an intermediary of thePI3KAKTpathway responsible for the protein synthesis) andsome Akt signalling networks Wu et al [162] demonstratedthat CAPE inhibits in vitro and in vivoMCF-7 andMDA-MB-231 tumour growthwithoutmuch effect on normalmammarycells by reducing the expression of growth and transcriptionfactors including NF-120581B Recently it was demonstrated thatCAPE effect on genes that are associated with tumour cellgrowth and survival is related in part to its role as a histonedeacetylase inhibitor [163]

As previously said propolis can also act by decreasingthe cancer stem cell population Using the putative CD44(+)CD24 (minuslow) breast cancer stem cells able to generatemammospheres from single cells Omene et al [164] showedthat CAPE caused a dose-dependent inhibition of cancerstem cells self-renewal progenitor formation and clonalgrowth

Concerning cell death some in vitro studies showeddifferent sensitivities of tumour cells to propolis extractsPWE from Iraq inhibits the proliferation of HL-60 cellsand leads to downregulation of Bcl-2 and activation of Bax[13] Alizadeh et al [165] investigated the protective effectsof Iranian PEE on N-methyl-N-nitro-N-nitrosoguanidine-(MNNG-) initiated gastric cancer in rats Results showedthat tumour incidence the number of lesions structuralabnormalities and beta-catenin of the animals group treatedwith PEE significantly declined compared with the controlPEE also induced the expression of proapoptotic Bax andreduced antiapoptotic Bcl-2 expression Propolis inhibitscolony formation potential and promotes necrotic changes inHCT-116 cells and decreases mitotic cells and increases p53and Ki-67 expression in HCT-116 tumor-bearing mice [13]Szliszkarsquos group have performed many studies to analyze theantitumour effect of different propolis and its constituentson prostate cancer cells (LNCaP and DU145) [166ndash168]Brazilian green PEE sensitized these cells to TRAIL-induceddeath enhanced the expression of TRAIL-R2 and decreasedthe activity of NF-120581B in LNCaP cells [167] Cotreatment ofTRAIL with artepillin C induced the significant activation ofcaspase-8 and caspase-3 as well as a significant disruption ofthe mitochondrial membrane potential [169] Many studieshave been conducted to understand the pathways involvedin the apoptotic effect of CAPE CAPE induces cell cyclearrest and apoptosis and reduces expression of NF-120581B inMDA-MB-231 and MCF-7 human breast cancer cells [162]In PC3 prostate cancer cells CAPE induced apoptosis in adose-dependent manner that was associated with the loss ofexpression of the inhibitors of apoptosis cIAP-1 cIAP-2 andXIAP [170] Cavaliere et al [171] showed that CAPE treatment

of lymphoblastoid cell line PL104 induced apoptosis throughthe mitochondrial intrinsic pathway

It has been known that cancer microenvironment isvery important for carcinogenesis and it consists of stromalendothelial immune and cancer cells Natural productslike propolis and their constituents have been shown tointerfere with this symbiosis It was demonstrated by Lee et al[172] that CAPE could effectively suppress the adhesion andinvasion potential of human hepatocellular carcinoma cells(SK-Hep1) by inhibiting the expression ofMMP-2 andMMP-9 and NF-120581B

Angiogenesis has a crucial role in tumour growth dueto the requirement of oxygen and nutrients to sustain rapiduncontrolled proliferation and metastization Both tumourand stromal cells can secrete proangiogenic factors thatstimulate the formation andmaintenance of new vessels suchas vascular endothelial growth factor (VEGF) [173] BrazilianPEE could significantly reduce the number of newly formedvessels and suppress the proliferation of human umbilicalvein endothelial cells (HUVECs) [174] this antiangiogeniceffect being mainly mediated via inducing apoptosis in tube-forming endothelial cells through the inactivation of the sur-vival signal ERK12 [175] Yun et al [176] observed that CAPEinhibited angiogenesis using the in vivo assay chick embryochorioallantoic membrane (CAM) CAPE also suppressesVEGF formation by MDA-MB-231 cells and formation ofcapillary-like tubes by endothelial cells [162 177] Extractsof propolis containing artepillin C and CAPE significantlyreduced the newly formed vessels and expression of MMPsand VEGF production from various cells [178] and inaccordance with this study Izuta et al [179] described thatCAPE promotes inhibition of VEGF expression in HUVECcells

The first study on the antitumor activity of Portuguesepropolis was only performed in 2010 Using normal andcancerous renal cells derived from human renal cell carci-noma (RCC) patients in addition to A-498 cell line Valenteet al [64] showed that methanolic extract of Portuguesepropolis exhibited selective toxicity against malignant cellscompared to normal cells and in vitro RCC growth wasstrongly inhibited Recently our group demonstrated theantitumour and antiangiogenic activity of the ethanol extractof Pereiro propolis (P10EE) collected in the district ofGuarda Portugal P10EE affects cell viability of differenttumour cells MDA-MB-231 (breast) and DU145 (prostate)being two of the most sensitive ones but was less cytotoxicagainst nontumour cells and fibroblasts Also it signifi-cantly decreased MDA-MB-231 and DU145 cell prolifera-tion and migration along time with cell cycle changesand increased cell death The significant increase observedin glucose consumption and lactate production could beexplained in MDA-MB-231 by an increased expression ofhypoxia inducible factor-1120572 pyruvate dehydrogenase kinaseglucose transporter 1 lactate dehydrogenase and carbonicanhydrase Furthermore P10EE induced a decrease inHBMECs total biomass and proliferation and decreasedvessel sprouting in the chicken chorioallantoic membrane[23]

5 Conclusions

From ancient to modern times herbs and other plant prod-ucts have been widely used as medicinal agents first in folkmedicine and other activities in many parts of the world andlater developed and improved on a scientific basis into drugsthat are used in the health system Propolis is one of thefew natural products that has maintained its popularity overa long period of time As reviewed here propolis containsa broad spectrum of compounds that may be useful in thetreatment of different pathological conditions In fact there ismuch literature that deals with the in vitro and in vivo biologi-cal properties of propolisThis wide range of bioactivities thecontinuous discovery of new compounds the long history ofpropolis use and its safety profile make propolis a potentialcandidate for drug discovery that may be useful in severalclinical scenarios Nevertheless it is necessary to make aneffort to standardize propolis composition since it seems thatpropolis biological properties and chemical composition notonly are variable but also are strictly linked In our opinionpropolis extracts may be important economically and wouldallow a relatively inexpensive treatment in different diseaseshowever to promote its use in modern medicine it will benecessary to identify and isolate the bioactive compoundsto be tested separately or in combination with other drugsalready available

Drug discovery does not consist only of the isolationof bioactive lead compounds from the natural sources Infact this process continues outside the academic laboratoriesthrough preclinical studies followed by clinical trials Thusdespite the in vitro and in vivo assays which provide newvaluable information on propolis biological properties andmechanisms of action it will be necessary to analyse theeffectiveness of propolis clinically to complement the basicresearch available and to evaluate the potential of propolis inhuman health promotion

8 Evidence-Based Complementary and Alternative Medicine

mechanisms investigated with propolis and its chemicalconstituents Recently the role of the flavonoids quercetinflavonols and flavones in modulating inflammatory cellfunction was studied [92] Funakoshi-Tago et al [96] inves-tigated the anti-inflammatory effects of flavonoids isolatedfrom Nepalese PEE on the IL-33 signaling pathway Theisolated flavonoids 3101584041015840-dihydroxy-4-methoxydalbergione4-methoxydalbergion cearoin and chrysin inhibited theexpression of inflammatory genes including IL-6 TNF-120572and IL-13 in bone marrow-derived mast cells (BMMC) andalso inhibited the activation of IKK which leads to thedegradation of I120581B120572 and inhibits the activation of nuclearfactor 120581B (NF-120581B)

The release and oxygenation of arachidonic acid are acritical event in inflammation Mirzoeva and Calder [90]demonstrated that propolis components such as CAPE caf-feic acid quercetin andnaringenin among others inhibit theproduction of eicosanoids In fact these components signif-icantly suppressed the lipoxygenase pathway of arachidonicacid metabolism CAPE being the most potent modulatorAnother study indicated that CAPE treatment improveshepatic steatosis induced by high-fat diet in a mouse modelThis effect was attributed to the reduction of c-Jun-N-terminal kinase (JNK12) andNF-120581B activationwith decreasein COX-2 expression [97] Recently it was reported thatCAPE exhibits inhibitory effects on the production of proin-flammatory cytokines (interleukin-1120573 (IL-1120573)) tumor necro-sis factor-120572 (TNF-120572) and monocyte chemoattractant pro-tein 1 (MCP-1) from lipopolysaccharide- (LPS-) stimulatedRAW2647 macrophages [98] Machado et al [99] showedthat Brazilian green propolis water extracts (PWE) modulatean anti-inflammatory cellular response in the model of LPS-induced pulmonary inflammation by decreasing the numberof macrophages and neutrophils Additionally it induced areduction in the secretion of IL-6 and TNF-120572 and an increasein TGF-120573 and IL-10 Another study showed that Brazilianred PEE promotes a significant decrease in renal macrophageinfiltration in rats with chronic kidney disease [100] Bufaloet al [101] demonstrated that Brazilian PEE and caffeicacid inhibited LPS-induced NO production by RAW2647macrophages acting at the transcriptional level and sug-gesting that their anti-inflammatory effects were mediatedby downregulating NF-120581B p38 MAP kinase and JNK12According to Naito et al [95] topical application of BrazilianPEE is effective in inhibiting carrageenan-induced rat hindpaw edemaThis sample appears to inhibit the chemotaxis ofhuman polymorphonuclear leukocytes (PMNs) which alsocontributes to its anti-inflammatory effects Another studyshowed the topical anti-inflammatory activity of propolisfrom Chile in mice ear with induced-edema In fact PEEfrom Buin Chile was the most active against the inflamma-tion induced by 12-O-tetradeca-noylphorbol-13-acetate andarachidonic acid and also inhibits significantly NO releaseby the macrophages [102] More recently Boudreau et al[103] indicated that CAPE is a potent leukotriene biosynthesisinhibitor in PMNs that blocks 5-lipoxygenase (5-LO) activityand arachidonic acid release A Croatian PEE may improvepsoriatic-like skin lesions whichwere induced in the study byirritant agents like n-hexyl salicylate or di-n-propyl disulfide

by reducing the lipid peroxidation in the skin and totalnumber of inflammatory cells in the skin and peritonealcavity more specially by suppressing functional activity ofmacrophages [104]

43 Immunomodulatory Activity Natural substances areconsidered alternative adjuvant therapies in the treatment ofdifferent diseases due to their immunomodulatory effectsInformation about this type of activity was scarce for propolisuntil the 1990s but published work in the last years has pro-vided information about the influence of different propolissamples on the immune system [65 105ndash112] (Table 4)

In a study using Brazilian green propolis it was seenthat the administration for 3 days of a PEE to male BALBcmice modulated the activation of the initial steps of theimmune response by upregulating toll-like receptor- (TLR-)2 and toll-like receptor-4 expression and proinflammatorycytokines (IL-1 and IL-6) production by macrophages andspleen cells [105] Another study demonstrated that BraziliangreenPEEupregulates TLR-4 andCD80 expression in humanmonocytes as well as TNF-120572 and IL-10 production [113] Itwas also shown that caffeic acid stimulates the activity ofmonocytes againstC albicans but it inhibits TLR-2 andHLA-DR expression as well as TNF-120572 and IL-10 production [114]

Additionally Missima et al [115] showed that Braziliangreen PEE administered to stressed mice reduces the proin-flammatory cytokines IL-1120573 and IL-6 When administered tomelanoma-bearing mice submitted or not to chronic stressit induces high levels of IL-1120573 and IL-6 and also stimu-lates Th1 cytokines production indicating the activation ofantitumour cell-mediated immunity Bachiega et al [116]investigated the immunomodulatory effect of propolis andcinnamic and coumaric acids on cytokines IL-1120573 IL-6 andIL-10 production Peritonealmacrophages fromBALBcmicewere incubated with different concentrations of propolis(5 50 and 100mgwell) and coumaric and cinnamic acid(50 and 100mgwell) Propolis and the acids stimulated IL-1120573 production and significantly inhibited IL-6 productionThen after LPS incubation the inhibitory concentrations ofcinnamic and coumaric acids prevented efficiently its effectson IL-6 production whereas propolis inhibited LPS effectsboth before and after its addition Additionally propolis andcoumaric and cinnamic acids inhibited IL-10 production Astudy which evaluated the effect of Brazilian green propolison macrophage activation by H

2O2and NO metabolite

determination [107] showed that propolis increased H2O2

generation and decreased NO generation which favoursthe microbicidal activity Recently the immunomodulatoryeffect of propolis collected in Brazil was evaluated in Leish-mania (Viannia) braziliensis experimental infection Datashows that macrophages incubated with propolis showed asignificant increase in interiorization and further killing ofparasites Also an increased TNF-120572 production was seen inpropolis-pretreated mice whereas IL-12 was downregulatedduring the infection [117]

The immunomodulatory action of propolis does notoccur only at the macrophage level In fact some studiesshow that this action has also an effect on lymphocyte pro-liferation [106 108] Sa-Nunes et al [108] showed inhibitory

10 Evidence-Based Complementary and Alternative Medicine

effects of Brazilian green propolis on splenocyte proliferationeffect that was attributed to flavonoids and enhancementeffects on interferon- (IFN-) 120574 production by spleen cellsCAPE displays inhibitory effects on transcription factors NF-120581B and NFAT and as a consequence inhibits IL-2 genetranscription IL-2 receptor expression and proliferation ofhuman T cells [94] This provides new information into themolecular mechanisms involved in the anti-inflammatoryand immunomodulatory activities of propolis CAPE hasvarious biological activities but its effect on the immunomod-ulatory activity remains little studied According to Wanget al [112] CAPE can be useful in the treatment of asthmaand other allergic diseases because it can inhibit cytokinesand chemokines production by human monocyte-deriveddendritic cells (MoDCs) which might be related to theNF-120581B signalling pathway Another study demonstrated forthe first time that Brazilian propolis significantly inhibitedthe generation of Th1 cells Furthermore the effects ofpropolis were investigated on 246-trinitrobenzene sulfonicacid- (TNBS-) induced colitis in a mouse model Propolisreduced the frequency of IFN-120574-producing CD4 T cellsin a dose-dependent way under Th1-polarizing conditionsThe inhibitory effect of propolis on Th1 differentiation wasdemonstrated in vivo too and the severity of colitis inpropolis-fed mice was significantly lower than that of micefed with the control diet [118]

44 Antiviral Activity Propolis comprises a complexity ofcompounds which play a role in antiviral protection Despitethe few data available regarding this activity it was shown thatpropolis from different geographic regions has considerableantiviral activity by acting at different levels and interferingwith the replication of some viruses [12] like herpes simplextypes 1 and 2 adenovirus type 2 influenza virus or humanimmunodeficiency virus (HIV) among others [7 60 119ndash124] Table 5 summarizes the antiviral activity of propolis andits chemical constituents

Schnitzler et al [123] analysed the antiviral effect ofPWE and PEE from Czech Republic as well as that ofthe constituents caffeic acid p-coumaric acid benzoic acidgalangin pinocembrin and chrysin against herpes simplexvirus type 1 (HSV-1) in cell culture Both extracts exhibitedhigh anti-HSV-1 activity when cells were treated prior toviral infection galangin and chrysin being the main bioac-tive compounds Amoros et al [60] showed the antiviralactivity of the major flavonoids of propolis more specificallyflavonols and flavones the first being more active againstHSV-1 Additionally they analysed the effect of propolis onseveral DNA and RNA viruses (HSV-1 HSV-2 adenovirustype 2 vesicular stomatitis virus (VSV) and poliovirus type2) Propolis at a concentration of 30120583gmL reduced thetiter of herpes virus however vesicular stomatitis virusand adenovirus were less susceptible In addition propo-lis appears to exert a virucidal action on the envelopedviruses HSV and VSV [120] Recently it was shown thathydromethanolic extract of geopropolis from the stinglessbee Scaptotrigona postica (Brazil) inhibits theHSV replicationand also the entry of the virus into cells effect that wasattributed to the C-glycosyl flavones catechin-3-O-gallate

and 34-dicaffeoylquinic acid [125] According to Tait etal [126] natural and synthetic flavonoids might interferewith picornavirus replication preventing the decapsidationof viral particles and RNA release within cells or blockingviral RNA synthesis These authors also showed that differ-ent homoisoflavonoids have good antiviral activity againstthe coxsackie viruses B3 B4 and A9 and echovirus 30Shvarzbeyn and Huleihel [127] tried to determine whichstep of Tax oncoprotein-induced NF-120581B activation is blockedby propolis and CAPE and showed that both substantiallyinhibited the activation of NF-120581B-dependent promoter byTax Also they strongly prevented both Tax binding to I120581B120572and its induced degradation by Tax Ma et al [128] showedthat nanometer propolis flavones could significantly inhibitin vitro porcine parvovirus (PPV) infecting PK-15 cells andin vivo they restrain the PPV copy in lung gonad and blooddecrease the impact of PPV on weight of guinea pigs andincrease hemagglutination inhibition of PPV in serum as wellas improving the contents of IL-2 IL-6 and 120574-IFN

Over recent years therapeutic benefits of propolis andorits isolated compounds have been described in HIV treat-ment Ito et al [129] tested the anti-HIV activity in H9lymphocytes of triterpenoids melliferone moronic acidanwuweizonic acid and betulonic acid and four knownaromatic compounds isolated from Brazilian propolis andshowed that moronic acid had significant anti-HIV activityGekker et al [119] assessed the anti-HIV-1 activity of propolisin CD4+ lymphocytes and microglial cell cultures observ-ing the inhibition of viral expression in a concentration-dependent wayThe possible mechanism of propolis antiviralproperty was suggested to involve inhibition of viral entry

45 Antimicrobial Activity Antimicrobial activity one ofthe most studied propolis biological properties is very welldocumented This bioactivity has been largely investigatedin the last years due to the need of new treatments againstinfectious diseases especially with the increase of resistantpathogens to current antibiotics Tables 6 and 7 summarisethe antibacterial and antifungal activities found in propolisfrom different geographic origin andor its chemical con-stituents

451 Antibacterial Activity Propolis effect against severalbacterial strains has evaluated [7 56ndash59 130] and supportedthe fact that propolis is more active against Gram-positivebacteria than Gram-negative bacteria [12 59] Briefly datafrom different studies showed that propolis inhibits bac-terial motility and enzyme activity exhibits bacteriostaticactivity against different bacterial genera can be bactericidalin high concentrations and affects cytoplasmic membrane[130]

Mirzoeva et al [130] investigated the effect of PEEon the physiology of Bacillus subtilis Escherichia coli andRhodobacter sphaeroides proposing that propolis and someof its components like cinnamic acid and flavonoids affectthe ion permeability of the inner bacterial membrane causingthe dissipation of the membrane potential and inhibitingbacterial motility A recent study [131] provided valuableinformation for understanding the potential anti-H pylori

mechanism of CAPE H pylori a major factor for gas-trointestinal illnesses contains the enzyme H pylori peptidedeformylase that catalyses the removal of formyl group fromthe N-terminus of nascent polypeptide chains Since theaction of this enzyme is essential for H pylori survival it isconsidered a promising therapeutic drug target Results fromabsorption spectra and crystal structural characterizationshowed that CAPE is a competitive inhibitor of peptidedeformylase blocking the substrate entrance and preventingsubstrate from approaching the active site [131]

It has been suggested that the combination of propoliswith other antibiotics would allow dose reduction of selectedantibiotics thus potentiating their effect The antibacterialactivity of Italian PEE in some clinically isolated Gram-positive strains as well as the synergetic effect with someantibiotics was assessed by Scazzocchio et al [56] Ital-ian PEE drastically increased the effect of ampicillin gen-tamycin and streptomycin and moderated the action ofchloramphenicol ceftriaxone and vancomycin No effectwas observed when used simultaneously with erythromycinWojtyczka et al [132] evaluated the in vitro antimicrobialactivity of a Polish PEE against methicillin-sensitive S aureus(MSSA) and methicillin-resistant S aureus (MRSA) clinicalisolates and also the combined effect of propolis with tenselected antistaphylococcal drugs PEE displayed varyingeffectiveness against twelve S aureus strains and potentiatedthe antimicrobial effect of eight antistaphylococcal againstall tested strains No synergism was observed in the caseof ciprofloxacin and chloramphenicol In another study theeffect of dichloromethane extract of French propolis againstdifferent human pathogenic bacterial strains was also testedAlthough Gram-negative bacteria were not susceptible tothe extract a significant antibacterial activity against bothmethicillin-resistant and methicillin-susceptible S aureusstrains was observed [133] The same was confirmed byVelikova et al [28] using different PEE from BulgariaGreece Turkey and Algeria All the samples showed agood antibacterial activity against S aureus but a week orlacking effect against E coli Australian PEE from stinglessbee Tetragonula carbonaria also inhibited the growth of Saureus Nevertheless it was less active against P aeruginosa[42] The same was observed by Papachroni et al [53]using PEE from Cameroon and CongoContrary to thesestudies Katircioglu and Mercan [134] showed that TurkishPEE was effective against Gram-negative bacteria like E coliOrsi et al [135] investigated the possible synergism betweenBrazilian and Bulgarian propolis and antibiotics acting onDNA (ciprofloxacin and norfloxacin) and on metabolism(cotrimoxazole) in Salmonella typhi Both samples hadantibacterial activity but no synergistic effect was detected

Recently the suitability of nanohydroxyapatite- (nano-HA-) based surfaces containing two Brazilian PEE (greenand red ones) to prevent S aureus bacterial growth andbiofilm was studied The nanoHA impregnated with thetwo highest concentrations (12 and 25120583gmL) of red PEEshowed a remarkable reduction of 99 in the number ofviable bacteria while nanoHA with green PEE at sameconcentrations showed a reduction of 45 and 61 Moreoverthe nanoHA impregnated with the highest concentration of

red PEE was able to inhibit 80 of the staphylococcal biofilmformation [136]

Diverse studies show that as the composition of propolisvaries from region to region the antibacterial activity alsodisplays some variations [59] Susceptibility of differentGram-positive bacteria to PEE varies with the place ofpropolis collection [137] The antibacterial effect was shownto be higher for samples from a wet-tropical rain forest-type climate Other studies revealed the influence of propolisgeographical origin on its antibacterial properties [57 58 138139] Propolis from the north and centre of Portugal has agreat activity against S aureus [58 140]

452 Antifungal Activity Antifungal activity is also influ-enced by the chemical variation of propolis [59] Severalstudies have shown the effect of propolis from differentgeographic origin against different fungi particularly ofclinical interest [141ndash145] Quiroga et al [146] demonstratedthe antifungal activity of propolis from the northwest ofArgentina focusing their study on the environment andthe development of agrochemicals with reduced economiccosts possibly containing propolis extracts and its isolatedcompounds such as pinocembrin and galangin as activeprinciples

Recently Falcao et al [140] screened the antifungalactivity of Portuguese propolis and its potential floral sourcesPopulus x Canadensis and Cistus ladanifer against Candidaalbicans Trichophyton rubrum and Aspergillus fumigatusPlant extracts did not exhibit relevant antifungal activity withexception of T rubrum but both propolis samples revealedsimilar antifungal activity the highest being obtained againstT rubrum and the lowest against A fumigatus A sample ofPEE from Poland showed a high fungicidal activity againstC albicans C glabrata and C krusei [147] Recently it wasshown that different organic extracts of French propolis (PEEPWEmethanolic extract and dichloromethane extract) wereeffective against C albicans and C glabrata but only have aweak activity towards A fumigates [133]

Brazilian PEE was proved to be active against severalCandida strains (C albicans C tropicalis C krusei andC guilliermondii) C albicans being the most sensitive andC guilliermondii the most resistant [141] Brazilian greenand red propolis display activity against different fungalspecies of Trichophyton which cause dermatophytosis redPEE being more efficient than the green one [143] Also itwas shown that n-hexane extract of Brazilian red propolisdid not induce resistance in Candida spp In fact it wasactive against Candida spp resistant to antifungal agentslike fluconazole [148] Dota et al [144] evaluated the in vitroantifungal activity of PEE and propolis microparticles (PMs)obtained from a sample from Argentina against clinical yeastisolates of importance in the vulvovaginal candidiasis Calbicans and non-C albicanswere inhibited by PEE and PMswith small variation Additionally it was shown that Braziliangreen PEE has the ability to inhibit growth and biofilmformation by C albicans from vulvovaginal candidiasis [149]Another study showed fungicide action of propolis (PEEPWE propolis matricial microparticles (PMM) and propolissoluble dry extract after 6ndash8-hour treatment against all three

C albicansmorphotypes (yeast pseudohyphae and hyphae)PEE being the most potent followed by PSDE PM andPWE [150] Brazilian propolis induces C albicans cell deathmediated via metacaspase since the metacaspase mutant inC albicans showed reduced sensitivity to propolis and bythe Ras pathway Using C albicans deletion libraries it waspossible to screen several mutants in genes involved eitherin the morphological transitions or in the maintenance of aspecific morphotype that are more sensitive to propolis Toconclude the study the authors also showed that propolisbased gels and cream were partially able to control vulvo-vaginal candidiasis in a mouse model [151] These studies[144] strongly indicate that propolis has a great potential tocontrol vulvovaginal candidiasis representing a promisingalternative therapeutic strategy

46 Antitumour Activity Recognition of the hallmarks ofcancer affects the search and development of new meth-ods and therapeutic agents with a sufficiently large thera-peutic window to kill tumour cells while sparing normalcells In the last years the natural product propolis hasattracted a growing interest by a large number of researcherssince it contains a variety of phytochemical compoundsthat may act through multiple pathways to reduce thedevelopment and other malignant characteristics of cancercells

Recently several in vitro studies have demonstrated acytotoxic action of propolis from different geographic originand of some of its isolated compounds on various tumourcells In vivo studies also show a potential in the developmentof new antitumor agents since propolis administration tomammals (eg rats) does not lead to detectable side effects[3] Briefly this natural product can block specific oncogenesignalling pathways which in turn lead to a decrease in cellproliferation and growth and can also act by decreasing thecancer stem cell population increasing apoptosis exertingantiangiogenic effects and modulating the tumour microen-vironment [66 152 153] Table 8 summarizes the antitumouractivity of propolis from different geographic origin and itschemical constituents

Some researchers showed the effect of different types ofpropolis and its constituents on cancer cell growth prolifera-tion and apoptosisThe hexane extract of propolis fromThai-land collected by the stingless bee Trigona laeviceps whichhas a different behavior in propolis collection compared tothe honey bees exerts antiproliferative activity against fivetested cancer cell lines (Chago KATO-III SW620 BT474and Hep-G2) but not against the normal cell lines tested(HS27 fibroblast and CH-liver) [5] A sample of PEE fromPoland inhibited human malignant melanoma (Me45) andcolorectal cancer (HCT 116) cells growth as well as reducedcell size [154]Other studies reported the antitumor activity ofBrazilianPEE [155ndash158]which regulate the protein expressionof cyclin D1 B1 and cyclin dependent kinase (CDK) as wellas p21 in human prostate cancer cells significantly affectingproliferation [158]

Although propolis containing CAPE is different fromthose with artepillin C it is possible to obtain a similarinhibitory effect from both types The effect of CAPE on

different cancer cell lines was analysed and many of itseffects have been shown to be mediated through inhibitionof NF-120581B [66 159] CAPE can inhibit the proliferation of thecolorectal cell line SW480 by decreasing the 120573-catenin c-myc and cyclin D1 protein expression [160] Chuu et al [161]observed that CAPE suppressed the proliferation of LNCaPDU-145 and PC-3 human prostate cancer cells in a dose-dependent manner and also inhibited the tumour growthof LNCaP xenografts in nude mice It was suggested that itacted through inhibition of p70S6K (an intermediary of thePI3KAKTpathway responsible for the protein synthesis) andsome Akt signalling networks Wu et al [162] demonstratedthat CAPE inhibits in vitro and in vivoMCF-7 andMDA-MB-231 tumour growthwithoutmuch effect on normalmammarycells by reducing the expression of growth and transcriptionfactors including NF-120581B Recently it was demonstrated thatCAPE effect on genes that are associated with tumour cellgrowth and survival is related in part to its role as a histonedeacetylase inhibitor [163]

As previously said propolis can also act by decreasingthe cancer stem cell population Using the putative CD44(+)CD24 (minuslow) breast cancer stem cells able to generatemammospheres from single cells Omene et al [164] showedthat CAPE caused a dose-dependent inhibition of cancerstem cells self-renewal progenitor formation and clonalgrowth

Concerning cell death some in vitro studies showeddifferent sensitivities of tumour cells to propolis extractsPWE from Iraq inhibits the proliferation of HL-60 cellsand leads to downregulation of Bcl-2 and activation of Bax[13] Alizadeh et al [165] investigated the protective effectsof Iranian PEE on N-methyl-N-nitro-N-nitrosoguanidine-(MNNG-) initiated gastric cancer in rats Results showedthat tumour incidence the number of lesions structuralabnormalities and beta-catenin of the animals group treatedwith PEE significantly declined compared with the controlPEE also induced the expression of proapoptotic Bax andreduced antiapoptotic Bcl-2 expression Propolis inhibitscolony formation potential and promotes necrotic changes inHCT-116 cells and decreases mitotic cells and increases p53and Ki-67 expression in HCT-116 tumor-bearing mice [13]Szliszkarsquos group have performed many studies to analyze theantitumour effect of different propolis and its constituentson prostate cancer cells (LNCaP and DU145) [166ndash168]Brazilian green PEE sensitized these cells to TRAIL-induceddeath enhanced the expression of TRAIL-R2 and decreasedthe activity of NF-120581B in LNCaP cells [167] Cotreatment ofTRAIL with artepillin C induced the significant activation ofcaspase-8 and caspase-3 as well as a significant disruption ofthe mitochondrial membrane potential [169] Many studieshave been conducted to understand the pathways involvedin the apoptotic effect of CAPE CAPE induces cell cyclearrest and apoptosis and reduces expression of NF-120581B inMDA-MB-231 and MCF-7 human breast cancer cells [162]In PC3 prostate cancer cells CAPE induced apoptosis in adose-dependent manner that was associated with the loss ofexpression of the inhibitors of apoptosis cIAP-1 cIAP-2 andXIAP [170] Cavaliere et al [171] showed that CAPE treatment

of lymphoblastoid cell line PL104 induced apoptosis throughthe mitochondrial intrinsic pathway

It has been known that cancer microenvironment isvery important for carcinogenesis and it consists of stromalendothelial immune and cancer cells Natural productslike propolis and their constituents have been shown tointerfere with this symbiosis It was demonstrated by Lee et al[172] that CAPE could effectively suppress the adhesion andinvasion potential of human hepatocellular carcinoma cells(SK-Hep1) by inhibiting the expression ofMMP-2 andMMP-9 and NF-120581B

Angiogenesis has a crucial role in tumour growth dueto the requirement of oxygen and nutrients to sustain rapiduncontrolled proliferation and metastization Both tumourand stromal cells can secrete proangiogenic factors thatstimulate the formation andmaintenance of new vessels suchas vascular endothelial growth factor (VEGF) [173] BrazilianPEE could significantly reduce the number of newly formedvessels and suppress the proliferation of human umbilicalvein endothelial cells (HUVECs) [174] this antiangiogeniceffect being mainly mediated via inducing apoptosis in tube-forming endothelial cells through the inactivation of the sur-vival signal ERK12 [175] Yun et al [176] observed that CAPEinhibited angiogenesis using the in vivo assay chick embryochorioallantoic membrane (CAM) CAPE also suppressesVEGF formation by MDA-MB-231 cells and formation ofcapillary-like tubes by endothelial cells [162 177] Extractsof propolis containing artepillin C and CAPE significantlyreduced the newly formed vessels and expression of MMPsand VEGF production from various cells [178] and inaccordance with this study Izuta et al [179] described thatCAPE promotes inhibition of VEGF expression in HUVECcells

The first study on the antitumor activity of Portuguesepropolis was only performed in 2010 Using normal andcancerous renal cells derived from human renal cell carci-noma (RCC) patients in addition to A-498 cell line Valenteet al [64] showed that methanolic extract of Portuguesepropolis exhibited selective toxicity against malignant cellscompared to normal cells and in vitro RCC growth wasstrongly inhibited Recently our group demonstrated theantitumour and antiangiogenic activity of the ethanol extractof Pereiro propolis (P10EE) collected in the district ofGuarda Portugal P10EE affects cell viability of differenttumour cells MDA-MB-231 (breast) and DU145 (prostate)being two of the most sensitive ones but was less cytotoxicagainst nontumour cells and fibroblasts Also it signifi-cantly decreased MDA-MB-231 and DU145 cell prolifera-tion and migration along time with cell cycle changesand increased cell death The significant increase observedin glucose consumption and lactate production could beexplained in MDA-MB-231 by an increased expression ofhypoxia inducible factor-1120572 pyruvate dehydrogenase kinaseglucose transporter 1 lactate dehydrogenase and carbonicanhydrase Furthermore P10EE induced a decrease inHBMECs total biomass and proliferation and decreasedvessel sprouting in the chicken chorioallantoic membrane[23]

5 Conclusions

From ancient to modern times herbs and other plant prod-ucts have been widely used as medicinal agents first in folkmedicine and other activities in many parts of the world andlater developed and improved on a scientific basis into drugsthat are used in the health system Propolis is one of thefew natural products that has maintained its popularity overa long period of time As reviewed here propolis containsa broad spectrum of compounds that may be useful in thetreatment of different pathological conditions In fact there ismuch literature that deals with the in vitro and in vivo biologi-cal properties of propolisThis wide range of bioactivities thecontinuous discovery of new compounds the long history ofpropolis use and its safety profile make propolis a potentialcandidate for drug discovery that may be useful in severalclinical scenarios Nevertheless it is necessary to make aneffort to standardize propolis composition since it seems thatpropolis biological properties and chemical composition notonly are variable but also are strictly linked In our opinionpropolis extracts may be important economically and wouldallow a relatively inexpensive treatment in different diseaseshowever to promote its use in modern medicine it will benecessary to identify and isolate the bioactive compoundsto be tested separately or in combination with other drugsalready available

Drug discovery does not consist only of the isolationof bioactive lead compounds from the natural sources Infact this process continues outside the academic laboratoriesthrough preclinical studies followed by clinical trials Thusdespite the in vitro and in vivo assays which provide newvaluable information on propolis biological properties andmechanisms of action it will be necessary to analyse theeffectiveness of propolis clinically to complement the basicresearch available and to evaluate the potential of propolis inhuman health promotion

8 Evidence-Based Complementary and Alternative Medicine

mechanisms investigated with propolis and its chemicalconstituents Recently the role of the flavonoids quercetinflavonols and flavones in modulating inflammatory cellfunction was studied [92] Funakoshi-Tago et al [96] inves-tigated the anti-inflammatory effects of flavonoids isolatedfrom Nepalese PEE on the IL-33 signaling pathway Theisolated flavonoids 3101584041015840-dihydroxy-4-methoxydalbergione4-methoxydalbergion cearoin and chrysin inhibited theexpression of inflammatory genes including IL-6 TNF-120572and IL-13 in bone marrow-derived mast cells (BMMC) andalso inhibited the activation of IKK which leads to thedegradation of I120581B120572 and inhibits the activation of nuclearfactor 120581B (NF-120581B)

The release and oxygenation of arachidonic acid are acritical event in inflammation Mirzoeva and Calder [90]demonstrated that propolis components such as CAPE caf-feic acid quercetin andnaringenin among others inhibit theproduction of eicosanoids In fact these components signif-icantly suppressed the lipoxygenase pathway of arachidonicacid metabolism CAPE being the most potent modulatorAnother study indicated that CAPE treatment improveshepatic steatosis induced by high-fat diet in a mouse modelThis effect was attributed to the reduction of c-Jun-N-terminal kinase (JNK12) andNF-120581B activationwith decreasein COX-2 expression [97] Recently it was reported thatCAPE exhibits inhibitory effects on the production of proin-flammatory cytokines (interleukin-1120573 (IL-1120573)) tumor necro-sis factor-120572 (TNF-120572) and monocyte chemoattractant pro-tein 1 (MCP-1) from lipopolysaccharide- (LPS-) stimulatedRAW2647 macrophages [98] Machado et al [99] showedthat Brazilian green propolis water extracts (PWE) modulatean anti-inflammatory cellular response in the model of LPS-induced pulmonary inflammation by decreasing the numberof macrophages and neutrophils Additionally it induced areduction in the secretion of IL-6 and TNF-120572 and an increasein TGF-120573 and IL-10 Another study showed that Brazilianred PEE promotes a significant decrease in renal macrophageinfiltration in rats with chronic kidney disease [100] Bufaloet al [101] demonstrated that Brazilian PEE and caffeicacid inhibited LPS-induced NO production by RAW2647macrophages acting at the transcriptional level and sug-gesting that their anti-inflammatory effects were mediatedby downregulating NF-120581B p38 MAP kinase and JNK12According to Naito et al [95] topical application of BrazilianPEE is effective in inhibiting carrageenan-induced rat hindpaw edemaThis sample appears to inhibit the chemotaxis ofhuman polymorphonuclear leukocytes (PMNs) which alsocontributes to its anti-inflammatory effects Another studyshowed the topical anti-inflammatory activity of propolisfrom Chile in mice ear with induced-edema In fact PEEfrom Buin Chile was the most active against the inflamma-tion induced by 12-O-tetradeca-noylphorbol-13-acetate andarachidonic acid and also inhibits significantly NO releaseby the macrophages [102] More recently Boudreau et al[103] indicated that CAPE is a potent leukotriene biosynthesisinhibitor in PMNs that blocks 5-lipoxygenase (5-LO) activityand arachidonic acid release A Croatian PEE may improvepsoriatic-like skin lesions whichwere induced in the study byirritant agents like n-hexyl salicylate or di-n-propyl disulfide

by reducing the lipid peroxidation in the skin and totalnumber of inflammatory cells in the skin and peritonealcavity more specially by suppressing functional activity ofmacrophages [104]

43 Immunomodulatory Activity Natural substances areconsidered alternative adjuvant therapies in the treatment ofdifferent diseases due to their immunomodulatory effectsInformation about this type of activity was scarce for propolisuntil the 1990s but published work in the last years has pro-vided information about the influence of different propolissamples on the immune system [65 105ndash112] (Table 4)

In a study using Brazilian green propolis it was seenthat the administration for 3 days of a PEE to male BALBcmice modulated the activation of the initial steps of theimmune response by upregulating toll-like receptor- (TLR-)2 and toll-like receptor-4 expression and proinflammatorycytokines (IL-1 and IL-6) production by macrophages andspleen cells [105] Another study demonstrated that BraziliangreenPEEupregulates TLR-4 andCD80 expression in humanmonocytes as well as TNF-120572 and IL-10 production [113] Itwas also shown that caffeic acid stimulates the activity ofmonocytes againstC albicans but it inhibits TLR-2 andHLA-DR expression as well as TNF-120572 and IL-10 production [114]

Additionally Missima et al [115] showed that Braziliangreen PEE administered to stressed mice reduces the proin-flammatory cytokines IL-1120573 and IL-6 When administered tomelanoma-bearing mice submitted or not to chronic stressit induces high levels of IL-1120573 and IL-6 and also stimu-lates Th1 cytokines production indicating the activation ofantitumour cell-mediated immunity Bachiega et al [116]investigated the immunomodulatory effect of propolis andcinnamic and coumaric acids on cytokines IL-1120573 IL-6 andIL-10 production Peritonealmacrophages fromBALBcmicewere incubated with different concentrations of propolis(5 50 and 100mgwell) and coumaric and cinnamic acid(50 and 100mgwell) Propolis and the acids stimulated IL-1120573 production and significantly inhibited IL-6 productionThen after LPS incubation the inhibitory concentrations ofcinnamic and coumaric acids prevented efficiently its effectson IL-6 production whereas propolis inhibited LPS effectsboth before and after its addition Additionally propolis andcoumaric and cinnamic acids inhibited IL-10 production Astudy which evaluated the effect of Brazilian green propolison macrophage activation by H

2O2and NO metabolite

determination [107] showed that propolis increased H2O2

generation and decreased NO generation which favoursthe microbicidal activity Recently the immunomodulatoryeffect of propolis collected in Brazil was evaluated in Leish-mania (Viannia) braziliensis experimental infection Datashows that macrophages incubated with propolis showed asignificant increase in interiorization and further killing ofparasites Also an increased TNF-120572 production was seen inpropolis-pretreated mice whereas IL-12 was downregulatedduring the infection [117]

The immunomodulatory action of propolis does notoccur only at the macrophage level In fact some studiesshow that this action has also an effect on lymphocyte pro-liferation [106 108] Sa-Nunes et al [108] showed inhibitory

10 Evidence-Based Complementary and Alternative Medicine

effects of Brazilian green propolis on splenocyte proliferationeffect that was attributed to flavonoids and enhancementeffects on interferon- (IFN-) 120574 production by spleen cellsCAPE displays inhibitory effects on transcription factors NF-120581B and NFAT and as a consequence inhibits IL-2 genetranscription IL-2 receptor expression and proliferation ofhuman T cells [94] This provides new information into themolecular mechanisms involved in the anti-inflammatoryand immunomodulatory activities of propolis CAPE hasvarious biological activities but its effect on the immunomod-ulatory activity remains little studied According to Wanget al [112] CAPE can be useful in the treatment of asthmaand other allergic diseases because it can inhibit cytokinesand chemokines production by human monocyte-deriveddendritic cells (MoDCs) which might be related to theNF-120581B signalling pathway Another study demonstrated forthe first time that Brazilian propolis significantly inhibitedthe generation of Th1 cells Furthermore the effects ofpropolis were investigated on 246-trinitrobenzene sulfonicacid- (TNBS-) induced colitis in a mouse model Propolisreduced the frequency of IFN-120574-producing CD4 T cellsin a dose-dependent way under Th1-polarizing conditionsThe inhibitory effect of propolis on Th1 differentiation wasdemonstrated in vivo too and the severity of colitis inpropolis-fed mice was significantly lower than that of micefed with the control diet [118]

44 Antiviral Activity Propolis comprises a complexity ofcompounds which play a role in antiviral protection Despitethe few data available regarding this activity it was shown thatpropolis from different geographic regions has considerableantiviral activity by acting at different levels and interferingwith the replication of some viruses [12] like herpes simplextypes 1 and 2 adenovirus type 2 influenza virus or humanimmunodeficiency virus (HIV) among others [7 60 119ndash124] Table 5 summarizes the antiviral activity of propolis andits chemical constituents

Schnitzler et al [123] analysed the antiviral effect ofPWE and PEE from Czech Republic as well as that ofthe constituents caffeic acid p-coumaric acid benzoic acidgalangin pinocembrin and chrysin against herpes simplexvirus type 1 (HSV-1) in cell culture Both extracts exhibitedhigh anti-HSV-1 activity when cells were treated prior toviral infection galangin and chrysin being the main bioac-tive compounds Amoros et al [60] showed the antiviralactivity of the major flavonoids of propolis more specificallyflavonols and flavones the first being more active againstHSV-1 Additionally they analysed the effect of propolis onseveral DNA and RNA viruses (HSV-1 HSV-2 adenovirustype 2 vesicular stomatitis virus (VSV) and poliovirus type2) Propolis at a concentration of 30120583gmL reduced thetiter of herpes virus however vesicular stomatitis virusand adenovirus were less susceptible In addition propo-lis appears to exert a virucidal action on the envelopedviruses HSV and VSV [120] Recently it was shown thathydromethanolic extract of geopropolis from the stinglessbee Scaptotrigona postica (Brazil) inhibits theHSV replicationand also the entry of the virus into cells effect that wasattributed to the C-glycosyl flavones catechin-3-O-gallate

and 34-dicaffeoylquinic acid [125] According to Tait etal [126] natural and synthetic flavonoids might interferewith picornavirus replication preventing the decapsidationof viral particles and RNA release within cells or blockingviral RNA synthesis These authors also showed that differ-ent homoisoflavonoids have good antiviral activity againstthe coxsackie viruses B3 B4 and A9 and echovirus 30Shvarzbeyn and Huleihel [127] tried to determine whichstep of Tax oncoprotein-induced NF-120581B activation is blockedby propolis and CAPE and showed that both substantiallyinhibited the activation of NF-120581B-dependent promoter byTax Also they strongly prevented both Tax binding to I120581B120572and its induced degradation by Tax Ma et al [128] showedthat nanometer propolis flavones could significantly inhibitin vitro porcine parvovirus (PPV) infecting PK-15 cells andin vivo they restrain the PPV copy in lung gonad and blooddecrease the impact of PPV on weight of guinea pigs andincrease hemagglutination inhibition of PPV in serum as wellas improving the contents of IL-2 IL-6 and 120574-IFN

Over recent years therapeutic benefits of propolis andorits isolated compounds have been described in HIV treat-ment Ito et al [129] tested the anti-HIV activity in H9lymphocytes of triterpenoids melliferone moronic acidanwuweizonic acid and betulonic acid and four knownaromatic compounds isolated from Brazilian propolis andshowed that moronic acid had significant anti-HIV activityGekker et al [119] assessed the anti-HIV-1 activity of propolisin CD4+ lymphocytes and microglial cell cultures observ-ing the inhibition of viral expression in a concentration-dependent wayThe possible mechanism of propolis antiviralproperty was suggested to involve inhibition of viral entry

45 Antimicrobial Activity Antimicrobial activity one ofthe most studied propolis biological properties is very welldocumented This bioactivity has been largely investigatedin the last years due to the need of new treatments againstinfectious diseases especially with the increase of resistantpathogens to current antibiotics Tables 6 and 7 summarisethe antibacterial and antifungal activities found in propolisfrom different geographic origin andor its chemical con-stituents

451 Antibacterial Activity Propolis effect against severalbacterial strains has evaluated [7 56ndash59 130] and supportedthe fact that propolis is more active against Gram-positivebacteria than Gram-negative bacteria [12 59] Briefly datafrom different studies showed that propolis inhibits bac-terial motility and enzyme activity exhibits bacteriostaticactivity against different bacterial genera can be bactericidalin high concentrations and affects cytoplasmic membrane[130]

Mirzoeva et al [130] investigated the effect of PEEon the physiology of Bacillus subtilis Escherichia coli andRhodobacter sphaeroides proposing that propolis and someof its components like cinnamic acid and flavonoids affectthe ion permeability of the inner bacterial membrane causingthe dissipation of the membrane potential and inhibitingbacterial motility A recent study [131] provided valuableinformation for understanding the potential anti-H pylori

mechanism of CAPE H pylori a major factor for gas-trointestinal illnesses contains the enzyme H pylori peptidedeformylase that catalyses the removal of formyl group fromthe N-terminus of nascent polypeptide chains Since theaction of this enzyme is essential for H pylori survival it isconsidered a promising therapeutic drug target Results fromabsorption spectra and crystal structural characterizationshowed that CAPE is a competitive inhibitor of peptidedeformylase blocking the substrate entrance and preventingsubstrate from approaching the active site [131]

It has been suggested that the combination of propoliswith other antibiotics would allow dose reduction of selectedantibiotics thus potentiating their effect The antibacterialactivity of Italian PEE in some clinically isolated Gram-positive strains as well as the synergetic effect with someantibiotics was assessed by Scazzocchio et al [56] Ital-ian PEE drastically increased the effect of ampicillin gen-tamycin and streptomycin and moderated the action ofchloramphenicol ceftriaxone and vancomycin No effectwas observed when used simultaneously with erythromycinWojtyczka et al [132] evaluated the in vitro antimicrobialactivity of a Polish PEE against methicillin-sensitive S aureus(MSSA) and methicillin-resistant S aureus (MRSA) clinicalisolates and also the combined effect of propolis with tenselected antistaphylococcal drugs PEE displayed varyingeffectiveness against twelve S aureus strains and potentiatedthe antimicrobial effect of eight antistaphylococcal againstall tested strains No synergism was observed in the caseof ciprofloxacin and chloramphenicol In another study theeffect of dichloromethane extract of French propolis againstdifferent human pathogenic bacterial strains was also testedAlthough Gram-negative bacteria were not susceptible tothe extract a significant antibacterial activity against bothmethicillin-resistant and methicillin-susceptible S aureusstrains was observed [133] The same was confirmed byVelikova et al [28] using different PEE from BulgariaGreece Turkey and Algeria All the samples showed agood antibacterial activity against S aureus but a week orlacking effect against E coli Australian PEE from stinglessbee Tetragonula carbonaria also inhibited the growth of Saureus Nevertheless it was less active against P aeruginosa[42] The same was observed by Papachroni et al [53]using PEE from Cameroon and CongoContrary to thesestudies Katircioglu and Mercan [134] showed that TurkishPEE was effective against Gram-negative bacteria like E coliOrsi et al [135] investigated the possible synergism betweenBrazilian and Bulgarian propolis and antibiotics acting onDNA (ciprofloxacin and norfloxacin) and on metabolism(cotrimoxazole) in Salmonella typhi Both samples hadantibacterial activity but no synergistic effect was detected

Recently the suitability of nanohydroxyapatite- (nano-HA-) based surfaces containing two Brazilian PEE (greenand red ones) to prevent S aureus bacterial growth andbiofilm was studied The nanoHA impregnated with thetwo highest concentrations (12 and 25120583gmL) of red PEEshowed a remarkable reduction of 99 in the number ofviable bacteria while nanoHA with green PEE at sameconcentrations showed a reduction of 45 and 61 Moreoverthe nanoHA impregnated with the highest concentration of

red PEE was able to inhibit 80 of the staphylococcal biofilmformation [136]

Diverse studies show that as the composition of propolisvaries from region to region the antibacterial activity alsodisplays some variations [59] Susceptibility of differentGram-positive bacteria to PEE varies with the place ofpropolis collection [137] The antibacterial effect was shownto be higher for samples from a wet-tropical rain forest-type climate Other studies revealed the influence of propolisgeographical origin on its antibacterial properties [57 58 138139] Propolis from the north and centre of Portugal has agreat activity against S aureus [58 140]

452 Antifungal Activity Antifungal activity is also influ-enced by the chemical variation of propolis [59] Severalstudies have shown the effect of propolis from differentgeographic origin against different fungi particularly ofclinical interest [141ndash145] Quiroga et al [146] demonstratedthe antifungal activity of propolis from the northwest ofArgentina focusing their study on the environment andthe development of agrochemicals with reduced economiccosts possibly containing propolis extracts and its isolatedcompounds such as pinocembrin and galangin as activeprinciples

Recently Falcao et al [140] screened the antifungalactivity of Portuguese propolis and its potential floral sourcesPopulus x Canadensis and Cistus ladanifer against Candidaalbicans Trichophyton rubrum and Aspergillus fumigatusPlant extracts did not exhibit relevant antifungal activity withexception of T rubrum but both propolis samples revealedsimilar antifungal activity the highest being obtained againstT rubrum and the lowest against A fumigatus A sample ofPEE from Poland showed a high fungicidal activity againstC albicans C glabrata and C krusei [147] Recently it wasshown that different organic extracts of French propolis (PEEPWEmethanolic extract and dichloromethane extract) wereeffective against C albicans and C glabrata but only have aweak activity towards A fumigates [133]

Brazilian PEE was proved to be active against severalCandida strains (C albicans C tropicalis C krusei andC guilliermondii) C albicans being the most sensitive andC guilliermondii the most resistant [141] Brazilian greenand red propolis display activity against different fungalspecies of Trichophyton which cause dermatophytosis redPEE being more efficient than the green one [143] Also itwas shown that n-hexane extract of Brazilian red propolisdid not induce resistance in Candida spp In fact it wasactive against Candida spp resistant to antifungal agentslike fluconazole [148] Dota et al [144] evaluated the in vitroantifungal activity of PEE and propolis microparticles (PMs)obtained from a sample from Argentina against clinical yeastisolates of importance in the vulvovaginal candidiasis Calbicans and non-C albicanswere inhibited by PEE and PMswith small variation Additionally it was shown that Braziliangreen PEE has the ability to inhibit growth and biofilmformation by C albicans from vulvovaginal candidiasis [149]Another study showed fungicide action of propolis (PEEPWE propolis matricial microparticles (PMM) and propolissoluble dry extract after 6ndash8-hour treatment against all three

Evidence-Based Complementary and Alternative Medicine 17

C albicansmorphotypes (yeast pseudohyphae and hyphae)PEE being the most potent followed by PSDE PM andPWE [150] Brazilian propolis induces C albicans cell deathmediated via metacaspase since the metacaspase mutant inC albicans showed reduced sensitivity to propolis and bythe Ras pathway Using C albicans deletion libraries it waspossible to screen several mutants in genes involved eitherin the morphological transitions or in the maintenance of aspecific morphotype that are more sensitive to propolis Toconclude the study the authors also showed that propolisbased gels and cream were partially able to control vulvo-vaginal candidiasis in a mouse model [151] These studies[144] strongly indicate that propolis has a great potential tocontrol vulvovaginal candidiasis representing a promisingalternative therapeutic strategy

46 Antitumour Activity Recognition of the hallmarks ofcancer affects the search and development of new meth-ods and therapeutic agents with a sufficiently large thera-peutic window to kill tumour cells while sparing normalcells In the last years the natural product propolis hasattracted a growing interest by a large number of researcherssince it contains a variety of phytochemical compoundsthat may act through multiple pathways to reduce thedevelopment and other malignant characteristics of cancercells

Recently several in vitro studies have demonstrated acytotoxic action of propolis from different geographic originand of some of its isolated compounds on various tumourcells In vivo studies also show a potential in the developmentof new antitumor agents since propolis administration tomammals (eg rats) does not lead to detectable side effects[3] Briefly this natural product can block specific oncogenesignalling pathways which in turn lead to a decrease in cellproliferation and growth and can also act by decreasing thecancer stem cell population increasing apoptosis exertingantiangiogenic effects and modulating the tumour microen-vironment [66 152 153] Table 8 summarizes the antitumouractivity of propolis from different geographic origin and itschemical constituents

Some researchers showed the effect of different types ofpropolis and its constituents on cancer cell growth prolifera-tion and apoptosisThe hexane extract of propolis fromThai-land collected by the stingless bee Trigona laeviceps whichhas a different behavior in propolis collection compared tothe honey bees exerts antiproliferative activity against fivetested cancer cell lines (Chago KATO-III SW620 BT474and Hep-G2) but not against the normal cell lines tested(HS27 fibroblast and CH-liver) [5] A sample of PEE fromPoland inhibited human malignant melanoma (Me45) andcolorectal cancer (HCT 116) cells growth as well as reducedcell size [154]Other studies reported the antitumor activity ofBrazilianPEE [155ndash158]which regulate the protein expressionof cyclin D1 B1 and cyclin dependent kinase (CDK) as wellas p21 in human prostate cancer cells significantly affectingproliferation [158]

Although propolis containing CAPE is different fromthose with artepillin C it is possible to obtain a similarinhibitory effect from both types The effect of CAPE on

different cancer cell lines was analysed and many of itseffects have been shown to be mediated through inhibitionof NF-120581B [66 159] CAPE can inhibit the proliferation of thecolorectal cell line SW480 by decreasing the 120573-catenin c-myc and cyclin D1 protein expression [160] Chuu et al [161]observed that CAPE suppressed the proliferation of LNCaPDU-145 and PC-3 human prostate cancer cells in a dose-dependent manner and also inhibited the tumour growthof LNCaP xenografts in nude mice It was suggested that itacted through inhibition of p70S6K (an intermediary of thePI3KAKTpathway responsible for the protein synthesis) andsome Akt signalling networks Wu et al [162] demonstratedthat CAPE inhibits in vitro and in vivoMCF-7 andMDA-MB-231 tumour growthwithoutmuch effect on normalmammarycells by reducing the expression of growth and transcriptionfactors including NF-120581B Recently it was demonstrated thatCAPE effect on genes that are associated with tumour cellgrowth and survival is related in part to its role as a histonedeacetylase inhibitor [163]

As previously said propolis can also act by decreasingthe cancer stem cell population Using the putative CD44(+)CD24 (minuslow) breast cancer stem cells able to generatemammospheres from single cells Omene et al [164] showedthat CAPE caused a dose-dependent inhibition of cancerstem cells self-renewal progenitor formation and clonalgrowth

Concerning cell death some in vitro studies showeddifferent sensitivities of tumour cells to propolis extractsPWE from Iraq inhibits the proliferation of HL-60 cellsand leads to downregulation of Bcl-2 and activation of Bax[13] Alizadeh et al [165] investigated the protective effectsof Iranian PEE on N-methyl-N-nitro-N-nitrosoguanidine-(MNNG-) initiated gastric cancer in rats Results showedthat tumour incidence the number of lesions structuralabnormalities and beta-catenin of the animals group treatedwith PEE significantly declined compared with the controlPEE also induced the expression of proapoptotic Bax andreduced antiapoptotic Bcl-2 expression Propolis inhibitscolony formation potential and promotes necrotic changes inHCT-116 cells and decreases mitotic cells and increases p53and Ki-67 expression in HCT-116 tumor-bearing mice [13]Szliszkarsquos group have performed many studies to analyze theantitumour effect of different propolis and its constituentson prostate cancer cells (LNCaP and DU145) [166ndash168]Brazilian green PEE sensitized these cells to TRAIL-induceddeath enhanced the expression of TRAIL-R2 and decreasedthe activity of NF-120581B in LNCaP cells [167] Cotreatment ofTRAIL with artepillin C induced the significant activation ofcaspase-8 and caspase-3 as well as a significant disruption ofthe mitochondrial membrane potential [169] Many studieshave been conducted to understand the pathways involvedin the apoptotic effect of CAPE CAPE induces cell cyclearrest and apoptosis and reduces expression of NF-120581B inMDA-MB-231 and MCF-7 human breast cancer cells [162]In PC3 prostate cancer cells CAPE induced apoptosis in adose-dependent manner that was associated with the loss ofexpression of the inhibitors of apoptosis cIAP-1 cIAP-2 andXIAP [170] Cavaliere et al [171] showed that CAPE treatment

of lymphoblastoid cell line PL104 induced apoptosis throughthe mitochondrial intrinsic pathway

It has been known that cancer microenvironment isvery important for carcinogenesis and it consists of stromalendothelial immune and cancer cells Natural productslike propolis and their constituents have been shown tointerfere with this symbiosis It was demonstrated by Lee et al[172] that CAPE could effectively suppress the adhesion andinvasion potential of human hepatocellular carcinoma cells(SK-Hep1) by inhibiting the expression ofMMP-2 andMMP-9 and NF-120581B

Angiogenesis has a crucial role in tumour growth dueto the requirement of oxygen and nutrients to sustain rapiduncontrolled proliferation and metastization Both tumourand stromal cells can secrete proangiogenic factors thatstimulate the formation andmaintenance of new vessels suchas vascular endothelial growth factor (VEGF) [173] BrazilianPEE could significantly reduce the number of newly formedvessels and suppress the proliferation of human umbilicalvein endothelial cells (HUVECs) [174] this antiangiogeniceffect being mainly mediated via inducing apoptosis in tube-forming endothelial cells through the inactivation of the sur-vival signal ERK12 [175] Yun et al [176] observed that CAPEinhibited angiogenesis using the in vivo assay chick embryochorioallantoic membrane (CAM) CAPE also suppressesVEGF formation by MDA-MB-231 cells and formation ofcapillary-like tubes by endothelial cells [162 177] Extractsof propolis containing artepillin C and CAPE significantlyreduced the newly formed vessels and expression of MMPsand VEGF production from various cells [178] and inaccordance with this study Izuta et al [179] described thatCAPE promotes inhibition of VEGF expression in HUVECcells

The first study on the antitumor activity of Portuguesepropolis was only performed in 2010 Using normal andcancerous renal cells derived from human renal cell carci-noma (RCC) patients in addition to A-498 cell line Valenteet al [64] showed that methanolic extract of Portuguesepropolis exhibited selective toxicity against malignant cellscompared to normal cells and in vitro RCC growth wasstrongly inhibited Recently our group demonstrated theantitumour and antiangiogenic activity of the ethanol extractof Pereiro propolis (P10EE) collected in the district ofGuarda Portugal P10EE affects cell viability of differenttumour cells MDA-MB-231 (breast) and DU145 (prostate)being two of the most sensitive ones but was less cytotoxicagainst nontumour cells and fibroblasts Also it signifi-cantly decreased MDA-MB-231 and DU145 cell prolifera-tion and migration along time with cell cycle changesand increased cell death The significant increase observedin glucose consumption and lactate production could beexplained in MDA-MB-231 by an increased expression ofhypoxia inducible factor-1120572 pyruvate dehydrogenase kinaseglucose transporter 1 lactate dehydrogenase and carbonicanhydrase Furthermore P10EE induced a decrease inHBMECs total biomass and proliferation and decreasedvessel sprouting in the chicken chorioallantoic membrane[23]

5 Conclusions

From ancient to modern times herbs and other plant prod-ucts have been widely used as medicinal agents first in folkmedicine and other activities in many parts of the world andlater developed and improved on a scientific basis into drugsthat are used in the health system Propolis is one of thefew natural products that has maintained its popularity overa long period of time As reviewed here propolis containsa broad spectrum of compounds that may be useful in thetreatment of different pathological conditions In fact there ismuch literature that deals with the in vitro and in vivo biologi-cal properties of propolisThis wide range of bioactivities thecontinuous discovery of new compounds the long history ofpropolis use and its safety profile make propolis a potentialcandidate for drug discovery that may be useful in severalclinical scenarios Nevertheless it is necessary to make aneffort to standardize propolis composition since it seems thatpropolis biological properties and chemical composition notonly are variable but also are strictly linked In our opinionpropolis extracts may be important economically and wouldallow a relatively inexpensive treatment in different diseaseshowever to promote its use in modern medicine it will benecessary to identify and isolate the bioactive compoundsto be tested separately or in combination with other drugsalready available

Drug discovery does not consist only of the isolationof bioactive lead compounds from the natural sources Infact this process continues outside the academic laboratoriesthrough preclinical studies followed by clinical trials Thusdespite the in vitro and in vivo assays which provide newvaluable information on propolis biological properties andmechanisms of action it will be necessary to analyse theeffectiveness of propolis clinically to complement the basicresearch available and to evaluate the potential of propolis inhuman health promotion

10 Evidence-Based Complementary and Alternative Medicine

effects of Brazilian green propolis on splenocyte proliferationeffect that was attributed to flavonoids and enhancementeffects on interferon- (IFN-) 120574 production by spleen cellsCAPE displays inhibitory effects on transcription factors NF-120581B and NFAT and as a consequence inhibits IL-2 genetranscription IL-2 receptor expression and proliferation ofhuman T cells [94] This provides new information into themolecular mechanisms involved in the anti-inflammatoryand immunomodulatory activities of propolis CAPE hasvarious biological activities but its effect on the immunomod-ulatory activity remains little studied According to Wanget al [112] CAPE can be useful in the treatment of asthmaand other allergic diseases because it can inhibit cytokinesand chemokines production by human monocyte-deriveddendritic cells (MoDCs) which might be related to theNF-120581B signalling pathway Another study demonstrated forthe first time that Brazilian propolis significantly inhibitedthe generation of Th1 cells Furthermore the effects ofpropolis were investigated on 246-trinitrobenzene sulfonicacid- (TNBS-) induced colitis in a mouse model Propolisreduced the frequency of IFN-120574-producing CD4 T cellsin a dose-dependent way under Th1-polarizing conditionsThe inhibitory effect of propolis on Th1 differentiation wasdemonstrated in vivo too and the severity of colitis inpropolis-fed mice was significantly lower than that of micefed with the control diet [118]

44 Antiviral Activity Propolis comprises a complexity ofcompounds which play a role in antiviral protection Despitethe few data available regarding this activity it was shown thatpropolis from different geographic regions has considerableantiviral activity by acting at different levels and interferingwith the replication of some viruses [12] like herpes simplextypes 1 and 2 adenovirus type 2 influenza virus or humanimmunodeficiency virus (HIV) among others [7 60 119ndash124] Table 5 summarizes the antiviral activity of propolis andits chemical constituents

Schnitzler et al [123] analysed the antiviral effect ofPWE and PEE from Czech Republic as well as that ofthe constituents caffeic acid p-coumaric acid benzoic acidgalangin pinocembrin and chrysin against herpes simplexvirus type 1 (HSV-1) in cell culture Both extracts exhibitedhigh anti-HSV-1 activity when cells were treated prior toviral infection galangin and chrysin being the main bioac-tive compounds Amoros et al [60] showed the antiviralactivity of the major flavonoids of propolis more specificallyflavonols and flavones the first being more active againstHSV-1 Additionally they analysed the effect of propolis onseveral DNA and RNA viruses (HSV-1 HSV-2 adenovirustype 2 vesicular stomatitis virus (VSV) and poliovirus type2) Propolis at a concentration of 30120583gmL reduced thetiter of herpes virus however vesicular stomatitis virusand adenovirus were less susceptible In addition propo-lis appears to exert a virucidal action on the envelopedviruses HSV and VSV [120] Recently it was shown thathydromethanolic extract of geopropolis from the stinglessbee Scaptotrigona postica (Brazil) inhibits theHSV replicationand also the entry of the virus into cells effect that wasattributed to the C-glycosyl flavones catechin-3-O-gallate

and 34-dicaffeoylquinic acid [125] According to Tait etal [126] natural and synthetic flavonoids might interferewith picornavirus replication preventing the decapsidationof viral particles and RNA release within cells or blockingviral RNA synthesis These authors also showed that differ-ent homoisoflavonoids have good antiviral activity againstthe coxsackie viruses B3 B4 and A9 and echovirus 30Shvarzbeyn and Huleihel [127] tried to determine whichstep of Tax oncoprotein-induced NF-120581B activation is blockedby propolis and CAPE and showed that both substantiallyinhibited the activation of NF-120581B-dependent promoter byTax Also they strongly prevented both Tax binding to I120581B120572and its induced degradation by Tax Ma et al [128] showedthat nanometer propolis flavones could significantly inhibitin vitro porcine parvovirus (PPV) infecting PK-15 cells andin vivo they restrain the PPV copy in lung gonad and blooddecrease the impact of PPV on weight of guinea pigs andincrease hemagglutination inhibition of PPV in serum as wellas improving the contents of IL-2 IL-6 and 120574-IFN

Over recent years therapeutic benefits of propolis andorits isolated compounds have been described in HIV treat-ment Ito et al [129] tested the anti-HIV activity in H9lymphocytes of triterpenoids melliferone moronic acidanwuweizonic acid and betulonic acid and four knownaromatic compounds isolated from Brazilian propolis andshowed that moronic acid had significant anti-HIV activityGekker et al [119] assessed the anti-HIV-1 activity of propolisin CD4+ lymphocytes and microglial cell cultures observ-ing the inhibition of viral expression in a concentration-dependent wayThe possible mechanism of propolis antiviralproperty was suggested to involve inhibition of viral entry

45 Antimicrobial Activity Antimicrobial activity one ofthe most studied propolis biological properties is very welldocumented This bioactivity has been largely investigatedin the last years due to the need of new treatments againstinfectious diseases especially with the increase of resistantpathogens to current antibiotics Tables 6 and 7 summarisethe antibacterial and antifungal activities found in propolisfrom different geographic origin andor its chemical con-stituents

451 Antibacterial Activity Propolis effect against severalbacterial strains has evaluated [7 56ndash59 130] and supportedthe fact that propolis is more active against Gram-positivebacteria than Gram-negative bacteria [12 59] Briefly datafrom different studies showed that propolis inhibits bac-terial motility and enzyme activity exhibits bacteriostaticactivity against different bacterial genera can be bactericidalin high concentrations and affects cytoplasmic membrane[130]

Mirzoeva et al [130] investigated the effect of PEEon the physiology of Bacillus subtilis Escherichia coli andRhodobacter sphaeroides proposing that propolis and someof its components like cinnamic acid and flavonoids affectthe ion permeability of the inner bacterial membrane causingthe dissipation of the membrane potential and inhibitingbacterial motility A recent study [131] provided valuableinformation for understanding the potential anti-H pylori

mechanism of CAPE H pylori a major factor for gas-trointestinal illnesses contains the enzyme H pylori peptidedeformylase that catalyses the removal of formyl group fromthe N-terminus of nascent polypeptide chains Since theaction of this enzyme is essential for H pylori survival it isconsidered a promising therapeutic drug target Results fromabsorption spectra and crystal structural characterizationshowed that CAPE is a competitive inhibitor of peptidedeformylase blocking the substrate entrance and preventingsubstrate from approaching the active site [131]

It has been suggested that the combination of propoliswith other antibiotics would allow dose reduction of selectedantibiotics thus potentiating their effect The antibacterialactivity of Italian PEE in some clinically isolated Gram-positive strains as well as the synergetic effect with someantibiotics was assessed by Scazzocchio et al [56] Ital-ian PEE drastically increased the effect of ampicillin gen-tamycin and streptomycin and moderated the action ofchloramphenicol ceftriaxone and vancomycin No effectwas observed when used simultaneously with erythromycinWojtyczka et al [132] evaluated the in vitro antimicrobialactivity of a Polish PEE against methicillin-sensitive S aureus(MSSA) and methicillin-resistant S aureus (MRSA) clinicalisolates and also the combined effect of propolis with tenselected antistaphylococcal drugs PEE displayed varyingeffectiveness against twelve S aureus strains and potentiatedthe antimicrobial effect of eight antistaphylococcal againstall tested strains No synergism was observed in the caseof ciprofloxacin and chloramphenicol In another study theeffect of dichloromethane extract of French propolis againstdifferent human pathogenic bacterial strains was also testedAlthough Gram-negative bacteria were not susceptible tothe extract a significant antibacterial activity against bothmethicillin-resistant and methicillin-susceptible S aureusstrains was observed [133] The same was confirmed byVelikova et al [28] using different PEE from BulgariaGreece Turkey and Algeria All the samples showed agood antibacterial activity against S aureus but a week orlacking effect against E coli Australian PEE from stinglessbee Tetragonula carbonaria also inhibited the growth of Saureus Nevertheless it was less active against P aeruginosa[42] The same was observed by Papachroni et al [53]using PEE from Cameroon and CongoContrary to thesestudies Katircioglu and Mercan [134] showed that TurkishPEE was effective against Gram-negative bacteria like E coliOrsi et al [135] investigated the possible synergism betweenBrazilian and Bulgarian propolis and antibiotics acting onDNA (ciprofloxacin and norfloxacin) and on metabolism(cotrimoxazole) in Salmonella typhi Both samples hadantibacterial activity but no synergistic effect was detected

Recently the suitability of nanohydroxyapatite- (nano-HA-) based surfaces containing two Brazilian PEE (greenand red ones) to prevent S aureus bacterial growth andbiofilm was studied The nanoHA impregnated with thetwo highest concentrations (12 and 25120583gmL) of red PEEshowed a remarkable reduction of 99 in the number ofviable bacteria while nanoHA with green PEE at sameconcentrations showed a reduction of 45 and 61 Moreoverthe nanoHA impregnated with the highest concentration of

red PEE was able to inhibit 80 of the staphylococcal biofilmformation [136]

Diverse studies show that as the composition of propolisvaries from region to region the antibacterial activity alsodisplays some variations [59] Susceptibility of differentGram-positive bacteria to PEE varies with the place ofpropolis collection [137] The antibacterial effect was shownto be higher for samples from a wet-tropical rain forest-type climate Other studies revealed the influence of propolisgeographical origin on its antibacterial properties [57 58 138139] Propolis from the north and centre of Portugal has agreat activity against S aureus [58 140]

452 Antifungal Activity Antifungal activity is also influ-enced by the chemical variation of propolis [59] Severalstudies have shown the effect of propolis from differentgeographic origin against different fungi particularly ofclinical interest [141ndash145] Quiroga et al [146] demonstratedthe antifungal activity of propolis from the northwest ofArgentina focusing their study on the environment andthe development of agrochemicals with reduced economiccosts possibly containing propolis extracts and its isolatedcompounds such as pinocembrin and galangin as activeprinciples

Recently Falcao et al [140] screened the antifungalactivity of Portuguese propolis and its potential floral sourcesPopulus x Canadensis and Cistus ladanifer against Candidaalbicans Trichophyton rubrum and Aspergillus fumigatusPlant extracts did not exhibit relevant antifungal activity withexception of T rubrum but both propolis samples revealedsimilar antifungal activity the highest being obtained againstT rubrum and the lowest against A fumigatus A sample ofPEE from Poland showed a high fungicidal activity againstC albicans C glabrata and C krusei [147] Recently it wasshown that different organic extracts of French propolis (PEEPWEmethanolic extract and dichloromethane extract) wereeffective against C albicans and C glabrata but only have aweak activity towards A fumigates [133]

Brazilian PEE was proved to be active against severalCandida strains (C albicans C tropicalis C krusei andC guilliermondii) C albicans being the most sensitive andC guilliermondii the most resistant [141] Brazilian greenand red propolis display activity against different fungalspecies of Trichophyton which cause dermatophytosis redPEE being more efficient than the green one [143] Also itwas shown that n-hexane extract of Brazilian red propolisdid not induce resistance in Candida spp In fact it wasactive against Candida spp resistant to antifungal agentslike fluconazole [148] Dota et al [144] evaluated the in vitroantifungal activity of PEE and propolis microparticles (PMs)obtained from a sample from Argentina against clinical yeastisolates of importance in the vulvovaginal candidiasis Calbicans and non-C albicanswere inhibited by PEE and PMswith small variation Additionally it was shown that Braziliangreen PEE has the ability to inhibit growth and biofilmformation by C albicans from vulvovaginal candidiasis [149]Another study showed fungicide action of propolis (PEEPWE propolis matricial microparticles (PMM) and propolissoluble dry extract after 6ndash8-hour treatment against all three

Evidence-Based Complementary and Alternative Medicine 17

C albicansmorphotypes (yeast pseudohyphae and hyphae)PEE being the most potent followed by PSDE PM andPWE [150] Brazilian propolis induces C albicans cell deathmediated via metacaspase since the metacaspase mutant inC albicans showed reduced sensitivity to propolis and bythe Ras pathway Using C albicans deletion libraries it waspossible to screen several mutants in genes involved eitherin the morphological transitions or in the maintenance of aspecific morphotype that are more sensitive to propolis Toconclude the study the authors also showed that propolisbased gels and cream were partially able to control vulvo-vaginal candidiasis in a mouse model [151] These studies[144] strongly indicate that propolis has a great potential tocontrol vulvovaginal candidiasis representing a promisingalternative therapeutic strategy

46 Antitumour Activity Recognition of the hallmarks ofcancer affects the search and development of new meth-ods and therapeutic agents with a sufficiently large thera-peutic window to kill tumour cells while sparing normalcells In the last years the natural product propolis hasattracted a growing interest by a large number of researcherssince it contains a variety of phytochemical compoundsthat may act through multiple pathways to reduce thedevelopment and other malignant characteristics of cancercells

Recently several in vitro studies have demonstrated acytotoxic action of propolis from different geographic originand of some of its isolated compounds on various tumourcells In vivo studies also show a potential in the developmentof new antitumor agents since propolis administration tomammals (eg rats) does not lead to detectable side effects[3] Briefly this natural product can block specific oncogenesignalling pathways which in turn lead to a decrease in cellproliferation and growth and can also act by decreasing thecancer stem cell population increasing apoptosis exertingantiangiogenic effects and modulating the tumour microen-vironment [66 152 153] Table 8 summarizes the antitumouractivity of propolis from different geographic origin and itschemical constituents

Some researchers showed the effect of different types ofpropolis and its constituents on cancer cell growth prolifera-tion and apoptosisThe hexane extract of propolis fromThai-land collected by the stingless bee Trigona laeviceps whichhas a different behavior in propolis collection compared tothe honey bees exerts antiproliferative activity against fivetested cancer cell lines (Chago KATO-III SW620 BT474and Hep-G2) but not against the normal cell lines tested(HS27 fibroblast and CH-liver) [5] A sample of PEE fromPoland inhibited human malignant melanoma (Me45) andcolorectal cancer (HCT 116) cells growth as well as reducedcell size [154]Other studies reported the antitumor activity ofBrazilianPEE [155ndash158]which regulate the protein expressionof cyclin D1 B1 and cyclin dependent kinase (CDK) as wellas p21 in human prostate cancer cells significantly affectingproliferation [158]

Although propolis containing CAPE is different fromthose with artepillin C it is possible to obtain a similarinhibitory effect from both types The effect of CAPE on

different cancer cell lines was analysed and many of itseffects have been shown to be mediated through inhibitionof NF-120581B [66 159] CAPE can inhibit the proliferation of thecolorectal cell line SW480 by decreasing the 120573-catenin c-myc and cyclin D1 protein expression [160] Chuu et al [161]observed that CAPE suppressed the proliferation of LNCaPDU-145 and PC-3 human prostate cancer cells in a dose-dependent manner and also inhibited the tumour growthof LNCaP xenografts in nude mice It was suggested that itacted through inhibition of p70S6K (an intermediary of thePI3KAKTpathway responsible for the protein synthesis) andsome Akt signalling networks Wu et al [162] demonstratedthat CAPE inhibits in vitro and in vivoMCF-7 andMDA-MB-231 tumour growthwithoutmuch effect on normalmammarycells by reducing the expression of growth and transcriptionfactors including NF-120581B Recently it was demonstrated thatCAPE effect on genes that are associated with tumour cellgrowth and survival is related in part to its role as a histonedeacetylase inhibitor [163]

As previously said propolis can also act by decreasingthe cancer stem cell population Using the putative CD44(+)CD24 (minuslow) breast cancer stem cells able to generatemammospheres from single cells Omene et al [164] showedthat CAPE caused a dose-dependent inhibition of cancerstem cells self-renewal progenitor formation and clonalgrowth

Concerning cell death some in vitro studies showeddifferent sensitivities of tumour cells to propolis extractsPWE from Iraq inhibits the proliferation of HL-60 cellsand leads to downregulation of Bcl-2 and activation of Bax[13] Alizadeh et al [165] investigated the protective effectsof Iranian PEE on N-methyl-N-nitro-N-nitrosoguanidine-(MNNG-) initiated gastric cancer in rats Results showedthat tumour incidence the number of lesions structuralabnormalities and beta-catenin of the animals group treatedwith PEE significantly declined compared with the controlPEE also induced the expression of proapoptotic Bax andreduced antiapoptotic Bcl-2 expression Propolis inhibitscolony formation potential and promotes necrotic changes inHCT-116 cells and decreases mitotic cells and increases p53and Ki-67 expression in HCT-116 tumor-bearing mice [13]Szliszkarsquos group have performed many studies to analyze theantitumour effect of different propolis and its constituentson prostate cancer cells (LNCaP and DU145) [166ndash168]Brazilian green PEE sensitized these cells to TRAIL-induceddeath enhanced the expression of TRAIL-R2 and decreasedthe activity of NF-120581B in LNCaP cells [167] Cotreatment ofTRAIL with artepillin C induced the significant activation ofcaspase-8 and caspase-3 as well as a significant disruption ofthe mitochondrial membrane potential [169] Many studieshave been conducted to understand the pathways involvedin the apoptotic effect of CAPE CAPE induces cell cyclearrest and apoptosis and reduces expression of NF-120581B inMDA-MB-231 and MCF-7 human breast cancer cells [162]In PC3 prostate cancer cells CAPE induced apoptosis in adose-dependent manner that was associated with the loss ofexpression of the inhibitors of apoptosis cIAP-1 cIAP-2 andXIAP [170] Cavaliere et al [171] showed that CAPE treatment

of lymphoblastoid cell line PL104 induced apoptosis throughthe mitochondrial intrinsic pathway

It has been known that cancer microenvironment isvery important for carcinogenesis and it consists of stromalendothelial immune and cancer cells Natural productslike propolis and their constituents have been shown tointerfere with this symbiosis It was demonstrated by Lee et al[172] that CAPE could effectively suppress the adhesion andinvasion potential of human hepatocellular carcinoma cells(SK-Hep1) by inhibiting the expression ofMMP-2 andMMP-9 and NF-120581B

Angiogenesis has a crucial role in tumour growth dueto the requirement of oxygen and nutrients to sustain rapiduncontrolled proliferation and metastization Both tumourand stromal cells can secrete proangiogenic factors thatstimulate the formation andmaintenance of new vessels suchas vascular endothelial growth factor (VEGF) [173] BrazilianPEE could significantly reduce the number of newly formedvessels and suppress the proliferation of human umbilicalvein endothelial cells (HUVECs) [174] this antiangiogeniceffect being mainly mediated via inducing apoptosis in tube-forming endothelial cells through the inactivation of the sur-vival signal ERK12 [175] Yun et al [176] observed that CAPEinhibited angiogenesis using the in vivo assay chick embryochorioallantoic membrane (CAM) CAPE also suppressesVEGF formation by MDA-MB-231 cells and formation ofcapillary-like tubes by endothelial cells [162 177] Extractsof propolis containing artepillin C and CAPE significantlyreduced the newly formed vessels and expression of MMPsand VEGF production from various cells [178] and inaccordance with this study Izuta et al [179] described thatCAPE promotes inhibition of VEGF expression in HUVECcells

The first study on the antitumor activity of Portuguesepropolis was only performed in 2010 Using normal andcancerous renal cells derived from human renal cell carci-noma (RCC) patients in addition to A-498 cell line Valenteet al [64] showed that methanolic extract of Portuguesepropolis exhibited selective toxicity against malignant cellscompared to normal cells and in vitro RCC growth wasstrongly inhibited Recently our group demonstrated theantitumour and antiangiogenic activity of the ethanol extractof Pereiro propolis (P10EE) collected in the district ofGuarda Portugal P10EE affects cell viability of differenttumour cells MDA-MB-231 (breast) and DU145 (prostate)being two of the most sensitive ones but was less cytotoxicagainst nontumour cells and fibroblasts Also it signifi-cantly decreased MDA-MB-231 and DU145 cell prolifera-tion and migration along time with cell cycle changesand increased cell death The significant increase observedin glucose consumption and lactate production could beexplained in MDA-MB-231 by an increased expression ofhypoxia inducible factor-1120572 pyruvate dehydrogenase kinaseglucose transporter 1 lactate dehydrogenase and carbonicanhydrase Furthermore P10EE induced a decrease inHBMECs total biomass and proliferation and decreasedvessel sprouting in the chicken chorioallantoic membrane[23]

5 Conclusions

From ancient to modern times herbs and other plant prod-ucts have been widely used as medicinal agents first in folkmedicine and other activities in many parts of the world andlater developed and improved on a scientific basis into drugsthat are used in the health system Propolis is one of thefew natural products that has maintained its popularity overa long period of time As reviewed here propolis containsa broad spectrum of compounds that may be useful in thetreatment of different pathological conditions In fact there ismuch literature that deals with the in vitro and in vivo biologi-cal properties of propolisThis wide range of bioactivities thecontinuous discovery of new compounds the long history ofpropolis use and its safety profile make propolis a potentialcandidate for drug discovery that may be useful in severalclinical scenarios Nevertheless it is necessary to make aneffort to standardize propolis composition since it seems thatpropolis biological properties and chemical composition notonly are variable but also are strictly linked In our opinionpropolis extracts may be important economically and wouldallow a relatively inexpensive treatment in different diseaseshowever to promote its use in modern medicine it will benecessary to identify and isolate the bioactive compoundsto be tested separately or in combination with other drugsalready available

Drug discovery does not consist only of the isolationof bioactive lead compounds from the natural sources Infact this process continues outside the academic laboratoriesthrough preclinical studies followed by clinical trials Thusdespite the in vitro and in vivo assays which provide newvaluable information on propolis biological properties andmechanisms of action it will be necessary to analyse theeffectiveness of propolis clinically to complement the basicresearch available and to evaluate the potential of propolis inhuman health promotion

effects of Brazilian green propolis on splenocyte proliferationeffect that was attributed to flavonoids and enhancementeffects on interferon- (IFN-) 120574 production by spleen cellsCAPE displays inhibitory effects on transcription factors NF-120581B and NFAT and as a consequence inhibits IL-2 genetranscription IL-2 receptor expression and proliferation ofhuman T cells [94] This provides new information into themolecular mechanisms involved in the anti-inflammatoryand immunomodulatory activities of propolis CAPE hasvarious biological activities but its effect on the immunomod-ulatory activity remains little studied According to Wanget al [112] CAPE can be useful in the treatment of asthmaand other allergic diseases because it can inhibit cytokinesand chemokines production by human monocyte-deriveddendritic cells (MoDCs) which might be related to theNF-120581B signalling pathway Another study demonstrated forthe first time that Brazilian propolis significantly inhibitedthe generation of Th1 cells Furthermore the effects ofpropolis were investigated on 246-trinitrobenzene sulfonicacid- (TNBS-) induced colitis in a mouse model Propolisreduced the frequency of IFN-120574-producing CD4 T cellsin a dose-dependent way under Th1-polarizing conditionsThe inhibitory effect of propolis on Th1 differentiation wasdemonstrated in vivo too and the severity of colitis inpropolis-fed mice was significantly lower than that of micefed with the control diet [118]

44 Antiviral Activity Propolis comprises a complexity ofcompounds which play a role in antiviral protection Despitethe few data available regarding this activity it was shown thatpropolis from different geographic regions has considerableantiviral activity by acting at different levels and interferingwith the replication of some viruses [12] like herpes simplextypes 1 and 2 adenovirus type 2 influenza virus or humanimmunodeficiency virus (HIV) among others [7 60 119ndash124] Table 5 summarizes the antiviral activity of propolis andits chemical constituents

Schnitzler et al [123] analysed the antiviral effect ofPWE and PEE from Czech Republic as well as that ofthe constituents caffeic acid p-coumaric acid benzoic acidgalangin pinocembrin and chrysin against herpes simplexvirus type 1 (HSV-1) in cell culture Both extracts exhibitedhigh anti-HSV-1 activity when cells were treated prior toviral infection galangin and chrysin being the main bioac-tive compounds Amoros et al [60] showed the antiviralactivity of the major flavonoids of propolis more specificallyflavonols and flavones the first being more active againstHSV-1 Additionally they analysed the effect of propolis onseveral DNA and RNA viruses (HSV-1 HSV-2 adenovirustype 2 vesicular stomatitis virus (VSV) and poliovirus type2) Propolis at a concentration of 30120583gmL reduced thetiter of herpes virus however vesicular stomatitis virusand adenovirus were less susceptible In addition propo-lis appears to exert a virucidal action on the envelopedviruses HSV and VSV [120] Recently it was shown thathydromethanolic extract of geopropolis from the stinglessbee Scaptotrigona postica (Brazil) inhibits theHSV replicationand also the entry of the virus into cells effect that wasattributed to the C-glycosyl flavones catechin-3-O-gallate

and 34-dicaffeoylquinic acid [125] According to Tait etal [126] natural and synthetic flavonoids might interferewith picornavirus replication preventing the decapsidationof viral particles and RNA release within cells or blockingviral RNA synthesis These authors also showed that differ-ent homoisoflavonoids have good antiviral activity againstthe coxsackie viruses B3 B4 and A9 and echovirus 30Shvarzbeyn and Huleihel [127] tried to determine whichstep of Tax oncoprotein-induced NF-120581B activation is blockedby propolis and CAPE and showed that both substantiallyinhibited the activation of NF-120581B-dependent promoter byTax Also they strongly prevented both Tax binding to I120581B120572and its induced degradation by Tax Ma et al [128] showedthat nanometer propolis flavones could significantly inhibitin vitro porcine parvovirus (PPV) infecting PK-15 cells andin vivo they restrain the PPV copy in lung gonad and blooddecrease the impact of PPV on weight of guinea pigs andincrease hemagglutination inhibition of PPV in serum as wellas improving the contents of IL-2 IL-6 and 120574-IFN

Over recent years therapeutic benefits of propolis andorits isolated compounds have been described in HIV treat-ment Ito et al [129] tested the anti-HIV activity in H9lymphocytes of triterpenoids melliferone moronic acidanwuweizonic acid and betulonic acid and four knownaromatic compounds isolated from Brazilian propolis andshowed that moronic acid had significant anti-HIV activityGekker et al [119] assessed the anti-HIV-1 activity of propolisin CD4+ lymphocytes and microglial cell cultures observ-ing the inhibition of viral expression in a concentration-dependent wayThe possible mechanism of propolis antiviralproperty was suggested to involve inhibition of viral entry

45 Antimicrobial Activity Antimicrobial activity one ofthe most studied propolis biological properties is very welldocumented This bioactivity has been largely investigatedin the last years due to the need of new treatments againstinfectious diseases especially with the increase of resistantpathogens to current antibiotics Tables 6 and 7 summarisethe antibacterial and antifungal activities found in propolisfrom different geographic origin andor its chemical con-stituents

451 Antibacterial Activity Propolis effect against severalbacterial strains has evaluated [7 56ndash59 130] and supportedthe fact that propolis is more active against Gram-positivebacteria than Gram-negative bacteria [12 59] Briefly datafrom different studies showed that propolis inhibits bac-terial motility and enzyme activity exhibits bacteriostaticactivity against different bacterial genera can be bactericidalin high concentrations and affects cytoplasmic membrane[130]

Mirzoeva et al [130] investigated the effect of PEEon the physiology of Bacillus subtilis Escherichia coli andRhodobacter sphaeroides proposing that propolis and someof its components like cinnamic acid and flavonoids affectthe ion permeability of the inner bacterial membrane causingthe dissipation of the membrane potential and inhibitingbacterial motility A recent study [131] provided valuableinformation for understanding the potential anti-H pylori

mechanism of CAPE H pylori a major factor for gas-trointestinal illnesses contains the enzyme H pylori peptidedeformylase that catalyses the removal of formyl group fromthe N-terminus of nascent polypeptide chains Since theaction of this enzyme is essential for H pylori survival it isconsidered a promising therapeutic drug target Results fromabsorption spectra and crystal structural characterizationshowed that CAPE is a competitive inhibitor of peptidedeformylase blocking the substrate entrance and preventingsubstrate from approaching the active site [131]

It has been suggested that the combination of propoliswith other antibiotics would allow dose reduction of selectedantibiotics thus potentiating their effect The antibacterialactivity of Italian PEE in some clinically isolated Gram-positive strains as well as the synergetic effect with someantibiotics was assessed by Scazzocchio et al [56] Ital-ian PEE drastically increased the effect of ampicillin gen-tamycin and streptomycin and moderated the action ofchloramphenicol ceftriaxone and vancomycin No effectwas observed when used simultaneously with erythromycinWojtyczka et al [132] evaluated the in vitro antimicrobialactivity of a Polish PEE against methicillin-sensitive S aureus(MSSA) and methicillin-resistant S aureus (MRSA) clinicalisolates and also the combined effect of propolis with tenselected antistaphylococcal drugs PEE displayed varyingeffectiveness against twelve S aureus strains and potentiatedthe antimicrobial effect of eight antistaphylococcal againstall tested strains No synergism was observed in the caseof ciprofloxacin and chloramphenicol In another study theeffect of dichloromethane extract of French propolis againstdifferent human pathogenic bacterial strains was also testedAlthough Gram-negative bacteria were not susceptible tothe extract a significant antibacterial activity against bothmethicillin-resistant and methicillin-susceptible S aureusstrains was observed [133] The same was confirmed byVelikova et al [28] using different PEE from BulgariaGreece Turkey and Algeria All the samples showed agood antibacterial activity against S aureus but a week orlacking effect against E coli Australian PEE from stinglessbee Tetragonula carbonaria also inhibited the growth of Saureus Nevertheless it was less active against P aeruginosa[42] The same was observed by Papachroni et al [53]using PEE from Cameroon and CongoContrary to thesestudies Katircioglu and Mercan [134] showed that TurkishPEE was effective against Gram-negative bacteria like E coliOrsi et al [135] investigated the possible synergism betweenBrazilian and Bulgarian propolis and antibiotics acting onDNA (ciprofloxacin and norfloxacin) and on metabolism(cotrimoxazole) in Salmonella typhi Both samples hadantibacterial activity but no synergistic effect was detected

Recently the suitability of nanohydroxyapatite- (nano-HA-) based surfaces containing two Brazilian PEE (greenand red ones) to prevent S aureus bacterial growth andbiofilm was studied The nanoHA impregnated with thetwo highest concentrations (12 and 25120583gmL) of red PEEshowed a remarkable reduction of 99 in the number ofviable bacteria while nanoHA with green PEE at sameconcentrations showed a reduction of 45 and 61 Moreoverthe nanoHA impregnated with the highest concentration of

red PEE was able to inhibit 80 of the staphylococcal biofilmformation [136]

Diverse studies show that as the composition of propolisvaries from region to region the antibacterial activity alsodisplays some variations [59] Susceptibility of differentGram-positive bacteria to PEE varies with the place ofpropolis collection [137] The antibacterial effect was shownto be higher for samples from a wet-tropical rain forest-type climate Other studies revealed the influence of propolisgeographical origin on its antibacterial properties [57 58 138139] Propolis from the north and centre of Portugal has agreat activity against S aureus [58 140]

452 Antifungal Activity Antifungal activity is also influ-enced by the chemical variation of propolis [59] Severalstudies have shown the effect of propolis from differentgeographic origin against different fungi particularly ofclinical interest [141ndash145] Quiroga et al [146] demonstratedthe antifungal activity of propolis from the northwest ofArgentina focusing their study on the environment andthe development of agrochemicals with reduced economiccosts possibly containing propolis extracts and its isolatedcompounds such as pinocembrin and galangin as activeprinciples

Recently Falcao et al [140] screened the antifungalactivity of Portuguese propolis and its potential floral sourcesPopulus x Canadensis and Cistus ladanifer against Candidaalbicans Trichophyton rubrum and Aspergillus fumigatusPlant extracts did not exhibit relevant antifungal activity withexception of T rubrum but both propolis samples revealedsimilar antifungal activity the highest being obtained againstT rubrum and the lowest against A fumigatus A sample ofPEE from Poland showed a high fungicidal activity againstC albicans C glabrata and C krusei [147] Recently it wasshown that different organic extracts of French propolis (PEEPWEmethanolic extract and dichloromethane extract) wereeffective against C albicans and C glabrata but only have aweak activity towards A fumigates [133]

Brazilian PEE was proved to be active against severalCandida strains (C albicans C tropicalis C krusei andC guilliermondii) C albicans being the most sensitive andC guilliermondii the most resistant [141] Brazilian greenand red propolis display activity against different fungalspecies of Trichophyton which cause dermatophytosis redPEE being more efficient than the green one [143] Also itwas shown that n-hexane extract of Brazilian red propolisdid not induce resistance in Candida spp In fact it wasactive against Candida spp resistant to antifungal agentslike fluconazole [148] Dota et al [144] evaluated the in vitroantifungal activity of PEE and propolis microparticles (PMs)obtained from a sample from Argentina against clinical yeastisolates of importance in the vulvovaginal candidiasis Calbicans and non-C albicanswere inhibited by PEE and PMswith small variation Additionally it was shown that Braziliangreen PEE has the ability to inhibit growth and biofilmformation by C albicans from vulvovaginal candidiasis [149]Another study showed fungicide action of propolis (PEEPWE propolis matricial microparticles (PMM) and propolissoluble dry extract after 6ndash8-hour treatment against all three

C albicansmorphotypes (yeast pseudohyphae and hyphae)PEE being the most potent followed by PSDE PM andPWE [150] Brazilian propolis induces C albicans cell deathmediated via metacaspase since the metacaspase mutant inC albicans showed reduced sensitivity to propolis and bythe Ras pathway Using C albicans deletion libraries it waspossible to screen several mutants in genes involved eitherin the morphological transitions or in the maintenance of aspecific morphotype that are more sensitive to propolis Toconclude the study the authors also showed that propolisbased gels and cream were partially able to control vulvo-vaginal candidiasis in a mouse model [151] These studies[144] strongly indicate that propolis has a great potential tocontrol vulvovaginal candidiasis representing a promisingalternative therapeutic strategy

46 Antitumour Activity Recognition of the hallmarks ofcancer affects the search and development of new meth-ods and therapeutic agents with a sufficiently large thera-peutic window to kill tumour cells while sparing normalcells In the last years the natural product propolis hasattracted a growing interest by a large number of researcherssince it contains a variety of phytochemical compoundsthat may act through multiple pathways to reduce thedevelopment and other malignant characteristics of cancercells

Recently several in vitro studies have demonstrated acytotoxic action of propolis from different geographic originand of some of its isolated compounds on various tumourcells In vivo studies also show a potential in the developmentof new antitumor agents since propolis administration tomammals (eg rats) does not lead to detectable side effects[3] Briefly this natural product can block specific oncogenesignalling pathways which in turn lead to a decrease in cellproliferation and growth and can also act by decreasing thecancer stem cell population increasing apoptosis exertingantiangiogenic effects and modulating the tumour microen-vironment [66 152 153] Table 8 summarizes the antitumouractivity of propolis from different geographic origin and itschemical constituents

Some researchers showed the effect of different types ofpropolis and its constituents on cancer cell growth prolifera-tion and apoptosisThe hexane extract of propolis fromThai-land collected by the stingless bee Trigona laeviceps whichhas a different behavior in propolis collection compared tothe honey bees exerts antiproliferative activity against fivetested cancer cell lines (Chago KATO-III SW620 BT474and Hep-G2) but not against the normal cell lines tested(HS27 fibroblast and CH-liver) [5] A sample of PEE fromPoland inhibited human malignant melanoma (Me45) andcolorectal cancer (HCT 116) cells growth as well as reducedcell size [154]Other studies reported the antitumor activity ofBrazilianPEE [155ndash158]which regulate the protein expressionof cyclin D1 B1 and cyclin dependent kinase (CDK) as wellas p21 in human prostate cancer cells significantly affectingproliferation [158]

Although propolis containing CAPE is different fromthose with artepillin C it is possible to obtain a similarinhibitory effect from both types The effect of CAPE on

different cancer cell lines was analysed and many of itseffects have been shown to be mediated through inhibitionof NF-120581B [66 159] CAPE can inhibit the proliferation of thecolorectal cell line SW480 by decreasing the 120573-catenin c-myc and cyclin D1 protein expression [160] Chuu et al [161]observed that CAPE suppressed the proliferation of LNCaPDU-145 and PC-3 human prostate cancer cells in a dose-dependent manner and also inhibited the tumour growthof LNCaP xenografts in nude mice It was suggested that itacted through inhibition of p70S6K (an intermediary of thePI3KAKTpathway responsible for the protein synthesis) andsome Akt signalling networks Wu et al [162] demonstratedthat CAPE inhibits in vitro and in vivoMCF-7 andMDA-MB-231 tumour growthwithoutmuch effect on normalmammarycells by reducing the expression of growth and transcriptionfactors including NF-120581B Recently it was demonstrated thatCAPE effect on genes that are associated with tumour cellgrowth and survival is related in part to its role as a histonedeacetylase inhibitor [163]

As previously said propolis can also act by decreasingthe cancer stem cell population Using the putative CD44(+)CD24 (minuslow) breast cancer stem cells able to generatemammospheres from single cells Omene et al [164] showedthat CAPE caused a dose-dependent inhibition of cancerstem cells self-renewal progenitor formation and clonalgrowth

Concerning cell death some in vitro studies showeddifferent sensitivities of tumour cells to propolis extractsPWE from Iraq inhibits the proliferation of HL-60 cellsand leads to downregulation of Bcl-2 and activation of Bax[13] Alizadeh et al [165] investigated the protective effectsof Iranian PEE on N-methyl-N-nitro-N-nitrosoguanidine-(MNNG-) initiated gastric cancer in rats Results showedthat tumour incidence the number of lesions structuralabnormalities and beta-catenin of the animals group treatedwith PEE significantly declined compared with the controlPEE also induced the expression of proapoptotic Bax andreduced antiapoptotic Bcl-2 expression Propolis inhibitscolony formation potential and promotes necrotic changes inHCT-116 cells and decreases mitotic cells and increases p53and Ki-67 expression in HCT-116 tumor-bearing mice [13]Szliszkarsquos group have performed many studies to analyze theantitumour effect of different propolis and its constituentson prostate cancer cells (LNCaP and DU145) [166ndash168]Brazilian green PEE sensitized these cells to TRAIL-induceddeath enhanced the expression of TRAIL-R2 and decreasedthe activity of NF-120581B in LNCaP cells [167] Cotreatment ofTRAIL with artepillin C induced the significant activation ofcaspase-8 and caspase-3 as well as a significant disruption ofthe mitochondrial membrane potential [169] Many studieshave been conducted to understand the pathways involvedin the apoptotic effect of CAPE CAPE induces cell cyclearrest and apoptosis and reduces expression of NF-120581B inMDA-MB-231 and MCF-7 human breast cancer cells [162]In PC3 prostate cancer cells CAPE induced apoptosis in adose-dependent manner that was associated with the loss ofexpression of the inhibitors of apoptosis cIAP-1 cIAP-2 andXIAP [170] Cavaliere et al [171] showed that CAPE treatment

of lymphoblastoid cell line PL104 induced apoptosis throughthe mitochondrial intrinsic pathway

It has been known that cancer microenvironment isvery important for carcinogenesis and it consists of stromalendothelial immune and cancer cells Natural productslike propolis and their constituents have been shown tointerfere with this symbiosis It was demonstrated by Lee et al[172] that CAPE could effectively suppress the adhesion andinvasion potential of human hepatocellular carcinoma cells(SK-Hep1) by inhibiting the expression ofMMP-2 andMMP-9 and NF-120581B

Angiogenesis has a crucial role in tumour growth dueto the requirement of oxygen and nutrients to sustain rapiduncontrolled proliferation and metastization Both tumourand stromal cells can secrete proangiogenic factors thatstimulate the formation andmaintenance of new vessels suchas vascular endothelial growth factor (VEGF) [173] BrazilianPEE could significantly reduce the number of newly formedvessels and suppress the proliferation of human umbilicalvein endothelial cells (HUVECs) [174] this antiangiogeniceffect being mainly mediated via inducing apoptosis in tube-forming endothelial cells through the inactivation of the sur-vival signal ERK12 [175] Yun et al [176] observed that CAPEinhibited angiogenesis using the in vivo assay chick embryochorioallantoic membrane (CAM) CAPE also suppressesVEGF formation by MDA-MB-231 cells and formation ofcapillary-like tubes by endothelial cells [162 177] Extractsof propolis containing artepillin C and CAPE significantlyreduced the newly formed vessels and expression of MMPsand VEGF production from various cells [178] and inaccordance with this study Izuta et al [179] described thatCAPE promotes inhibition of VEGF expression in HUVECcells

The first study on the antitumor activity of Portuguesepropolis was only performed in 2010 Using normal andcancerous renal cells derived from human renal cell carci-noma (RCC) patients in addition to A-498 cell line Valenteet al [64] showed that methanolic extract of Portuguesepropolis exhibited selective toxicity against malignant cellscompared to normal cells and in vitro RCC growth wasstrongly inhibited Recently our group demonstrated theantitumour and antiangiogenic activity of the ethanol extractof Pereiro propolis (P10EE) collected in the district ofGuarda Portugal P10EE affects cell viability of differenttumour cells MDA-MB-231 (breast) and DU145 (prostate)being two of the most sensitive ones but was less cytotoxicagainst nontumour cells and fibroblasts Also it signifi-cantly decreased MDA-MB-231 and DU145 cell prolifera-tion and migration along time with cell cycle changesand increased cell death The significant increase observedin glucose consumption and lactate production could beexplained in MDA-MB-231 by an increased expression ofhypoxia inducible factor-1120572 pyruvate dehydrogenase kinaseglucose transporter 1 lactate dehydrogenase and carbonicanhydrase Furthermore P10EE induced a decrease inHBMECs total biomass and proliferation and decreasedvessel sprouting in the chicken chorioallantoic membrane[23]

5 Conclusions

From ancient to modern times herbs and other plant prod-ucts have been widely used as medicinal agents first in folkmedicine and other activities in many parts of the world andlater developed and improved on a scientific basis into drugsthat are used in the health system Propolis is one of thefew natural products that has maintained its popularity overa long period of time As reviewed here propolis containsa broad spectrum of compounds that may be useful in thetreatment of different pathological conditions In fact there ismuch literature that deals with the in vitro and in vivo biologi-cal properties of propolisThis wide range of bioactivities thecontinuous discovery of new compounds the long history ofpropolis use and its safety profile make propolis a potentialcandidate for drug discovery that may be useful in severalclinical scenarios Nevertheless it is necessary to make aneffort to standardize propolis composition since it seems thatpropolis biological properties and chemical composition notonly are variable but also are strictly linked In our opinionpropolis extracts may be important economically and wouldallow a relatively inexpensive treatment in different diseaseshowever to promote its use in modern medicine it will benecessary to identify and isolate the bioactive compoundsto be tested separately or in combination with other drugsalready available

Drug discovery does not consist only of the isolationof bioactive lead compounds from the natural sources Infact this process continues outside the academic laboratoriesthrough preclinical studies followed by clinical trials Thusdespite the in vitro and in vivo assays which provide newvaluable information on propolis biological properties andmechanisms of action it will be necessary to analyse theeffectiveness of propolis clinically to complement the basicresearch available and to evaluate the potential of propolis inhuman health promotion

mechanism of CAPE H pylori a major factor for gas-trointestinal illnesses contains the enzyme H pylori peptidedeformylase that catalyses the removal of formyl group fromthe N-terminus of nascent polypeptide chains Since theaction of this enzyme is essential for H pylori survival it isconsidered a promising therapeutic drug target Results fromabsorption spectra and crystal structural characterizationshowed that CAPE is a competitive inhibitor of peptidedeformylase blocking the substrate entrance and preventingsubstrate from approaching the active site [131]

It has been suggested that the combination of propoliswith other antibiotics would allow dose reduction of selectedantibiotics thus potentiating their effect The antibacterialactivity of Italian PEE in some clinically isolated Gram-positive strains as well as the synergetic effect with someantibiotics was assessed by Scazzocchio et al [56] Ital-ian PEE drastically increased the effect of ampicillin gen-tamycin and streptomycin and moderated the action ofchloramphenicol ceftriaxone and vancomycin No effectwas observed when used simultaneously with erythromycinWojtyczka et al [132] evaluated the in vitro antimicrobialactivity of a Polish PEE against methicillin-sensitive S aureus(MSSA) and methicillin-resistant S aureus (MRSA) clinicalisolates and also the combined effect of propolis with tenselected antistaphylococcal drugs PEE displayed varyingeffectiveness against twelve S aureus strains and potentiatedthe antimicrobial effect of eight antistaphylococcal againstall tested strains No synergism was observed in the caseof ciprofloxacin and chloramphenicol In another study theeffect of dichloromethane extract of French propolis againstdifferent human pathogenic bacterial strains was also testedAlthough Gram-negative bacteria were not susceptible tothe extract a significant antibacterial activity against bothmethicillin-resistant and methicillin-susceptible S aureusstrains was observed [133] The same was confirmed byVelikova et al [28] using different PEE from BulgariaGreece Turkey and Algeria All the samples showed agood antibacterial activity against S aureus but a week orlacking effect against E coli Australian PEE from stinglessbee Tetragonula carbonaria also inhibited the growth of Saureus Nevertheless it was less active against P aeruginosa[42] The same was observed by Papachroni et al [53]using PEE from Cameroon and CongoContrary to thesestudies Katircioglu and Mercan [134] showed that TurkishPEE was effective against Gram-negative bacteria like E coliOrsi et al [135] investigated the possible synergism betweenBrazilian and Bulgarian propolis and antibiotics acting onDNA (ciprofloxacin and norfloxacin) and on metabolism(cotrimoxazole) in Salmonella typhi Both samples hadantibacterial activity but no synergistic effect was detected

Recently the suitability of nanohydroxyapatite- (nano-HA-) based surfaces containing two Brazilian PEE (greenand red ones) to prevent S aureus bacterial growth andbiofilm was studied The nanoHA impregnated with thetwo highest concentrations (12 and 25120583gmL) of red PEEshowed a remarkable reduction of 99 in the number ofviable bacteria while nanoHA with green PEE at sameconcentrations showed a reduction of 45 and 61 Moreoverthe nanoHA impregnated with the highest concentration of

red PEE was able to inhibit 80 of the staphylococcal biofilmformation [136]

Diverse studies show that as the composition of propolisvaries from region to region the antibacterial activity alsodisplays some variations [59] Susceptibility of differentGram-positive bacteria to PEE varies with the place ofpropolis collection [137] The antibacterial effect was shownto be higher for samples from a wet-tropical rain forest-type climate Other studies revealed the influence of propolisgeographical origin on its antibacterial properties [57 58 138139] Propolis from the north and centre of Portugal has agreat activity against S aureus [58 140]

452 Antifungal Activity Antifungal activity is also influ-enced by the chemical variation of propolis [59] Severalstudies have shown the effect of propolis from differentgeographic origin against different fungi particularly ofclinical interest [141ndash145] Quiroga et al [146] demonstratedthe antifungal activity of propolis from the northwest ofArgentina focusing their study on the environment andthe development of agrochemicals with reduced economiccosts possibly containing propolis extracts and its isolatedcompounds such as pinocembrin and galangin as activeprinciples

Recently Falcao et al [140] screened the antifungalactivity of Portuguese propolis and its potential floral sourcesPopulus x Canadensis and Cistus ladanifer against Candidaalbicans Trichophyton rubrum and Aspergillus fumigatusPlant extracts did not exhibit relevant antifungal activity withexception of T rubrum but both propolis samples revealedsimilar antifungal activity the highest being obtained againstT rubrum and the lowest against A fumigatus A sample ofPEE from Poland showed a high fungicidal activity againstC albicans C glabrata and C krusei [147] Recently it wasshown that different organic extracts of French propolis (PEEPWEmethanolic extract and dichloromethane extract) wereeffective against C albicans and C glabrata but only have aweak activity towards A fumigates [133]

Brazilian PEE was proved to be active against severalCandida strains (C albicans C tropicalis C krusei andC guilliermondii) C albicans being the most sensitive andC guilliermondii the most resistant [141] Brazilian greenand red propolis display activity against different fungalspecies of Trichophyton which cause dermatophytosis redPEE being more efficient than the green one [143] Also itwas shown that n-hexane extract of Brazilian red propolisdid not induce resistance in Candida spp In fact it wasactive against Candida spp resistant to antifungal agentslike fluconazole [148] Dota et al [144] evaluated the in vitroantifungal activity of PEE and propolis microparticles (PMs)obtained from a sample from Argentina against clinical yeastisolates of importance in the vulvovaginal candidiasis Calbicans and non-C albicanswere inhibited by PEE and PMswith small variation Additionally it was shown that Braziliangreen PEE has the ability to inhibit growth and biofilmformation by C albicans from vulvovaginal candidiasis [149]Another study showed fungicide action of propolis (PEEPWE propolis matricial microparticles (PMM) and propolissoluble dry extract after 6ndash8-hour treatment against all three

Evidence-Based Complementary and Alternative Medicine 17

C albicansmorphotypes (yeast pseudohyphae and hyphae)PEE being the most potent followed by PSDE PM andPWE [150] Brazilian propolis induces C albicans cell deathmediated via metacaspase since the metacaspase mutant inC albicans showed reduced sensitivity to propolis and bythe Ras pathway Using C albicans deletion libraries it waspossible to screen several mutants in genes involved eitherin the morphological transitions or in the maintenance of aspecific morphotype that are more sensitive to propolis Toconclude the study the authors also showed that propolisbased gels and cream were partially able to control vulvo-vaginal candidiasis in a mouse model [151] These studies[144] strongly indicate that propolis has a great potential tocontrol vulvovaginal candidiasis representing a promisingalternative therapeutic strategy

46 Antitumour Activity Recognition of the hallmarks ofcancer affects the search and development of new meth-ods and therapeutic agents with a sufficiently large thera-peutic window to kill tumour cells while sparing normalcells In the last years the natural product propolis hasattracted a growing interest by a large number of researcherssince it contains a variety of phytochemical compoundsthat may act through multiple pathways to reduce thedevelopment and other malignant characteristics of cancercells

Recently several in vitro studies have demonstrated acytotoxic action of propolis from different geographic originand of some of its isolated compounds on various tumourcells In vivo studies also show a potential in the developmentof new antitumor agents since propolis administration tomammals (eg rats) does not lead to detectable side effects[3] Briefly this natural product can block specific oncogenesignalling pathways which in turn lead to a decrease in cellproliferation and growth and can also act by decreasing thecancer stem cell population increasing apoptosis exertingantiangiogenic effects and modulating the tumour microen-vironment [66 152 153] Table 8 summarizes the antitumouractivity of propolis from different geographic origin and itschemical constituents

Some researchers showed the effect of different types ofpropolis and its constituents on cancer cell growth prolifera-tion and apoptosisThe hexane extract of propolis fromThai-land collected by the stingless bee Trigona laeviceps whichhas a different behavior in propolis collection compared tothe honey bees exerts antiproliferative activity against fivetested cancer cell lines (Chago KATO-III SW620 BT474and Hep-G2) but not against the normal cell lines tested(HS27 fibroblast and CH-liver) [5] A sample of PEE fromPoland inhibited human malignant melanoma (Me45) andcolorectal cancer (HCT 116) cells growth as well as reducedcell size [154]Other studies reported the antitumor activity ofBrazilianPEE [155ndash158]which regulate the protein expressionof cyclin D1 B1 and cyclin dependent kinase (CDK) as wellas p21 in human prostate cancer cells significantly affectingproliferation [158]

Although propolis containing CAPE is different fromthose with artepillin C it is possible to obtain a similarinhibitory effect from both types The effect of CAPE on

different cancer cell lines was analysed and many of itseffects have been shown to be mediated through inhibitionof NF-120581B [66 159] CAPE can inhibit the proliferation of thecolorectal cell line SW480 by decreasing the 120573-catenin c-myc and cyclin D1 protein expression [160] Chuu et al [161]observed that CAPE suppressed the proliferation of LNCaPDU-145 and PC-3 human prostate cancer cells in a dose-dependent manner and also inhibited the tumour growthof LNCaP xenografts in nude mice It was suggested that itacted through inhibition of p70S6K (an intermediary of thePI3KAKTpathway responsible for the protein synthesis) andsome Akt signalling networks Wu et al [162] demonstratedthat CAPE inhibits in vitro and in vivoMCF-7 andMDA-MB-231 tumour growthwithoutmuch effect on normalmammarycells by reducing the expression of growth and transcriptionfactors including NF-120581B Recently it was demonstrated thatCAPE effect on genes that are associated with tumour cellgrowth and survival is related in part to its role as a histonedeacetylase inhibitor [163]

As previously said propolis can also act by decreasingthe cancer stem cell population Using the putative CD44(+)CD24 (minuslow) breast cancer stem cells able to generatemammospheres from single cells Omene et al [164] showedthat CAPE caused a dose-dependent inhibition of cancerstem cells self-renewal progenitor formation and clonalgrowth

Concerning cell death some in vitro studies showeddifferent sensitivities of tumour cells to propolis extractsPWE from Iraq inhibits the proliferation of HL-60 cellsand leads to downregulation of Bcl-2 and activation of Bax[13] Alizadeh et al [165] investigated the protective effectsof Iranian PEE on N-methyl-N-nitro-N-nitrosoguanidine-(MNNG-) initiated gastric cancer in rats Results showedthat tumour incidence the number of lesions structuralabnormalities and beta-catenin of the animals group treatedwith PEE significantly declined compared with the controlPEE also induced the expression of proapoptotic Bax andreduced antiapoptotic Bcl-2 expression Propolis inhibitscolony formation potential and promotes necrotic changes inHCT-116 cells and decreases mitotic cells and increases p53and Ki-67 expression in HCT-116 tumor-bearing mice [13]Szliszkarsquos group have performed many studies to analyze theantitumour effect of different propolis and its constituentson prostate cancer cells (LNCaP and DU145) [166ndash168]Brazilian green PEE sensitized these cells to TRAIL-induceddeath enhanced the expression of TRAIL-R2 and decreasedthe activity of NF-120581B in LNCaP cells [167] Cotreatment ofTRAIL with artepillin C induced the significant activation ofcaspase-8 and caspase-3 as well as a significant disruption ofthe mitochondrial membrane potential [169] Many studieshave been conducted to understand the pathways involvedin the apoptotic effect of CAPE CAPE induces cell cyclearrest and apoptosis and reduces expression of NF-120581B inMDA-MB-231 and MCF-7 human breast cancer cells [162]In PC3 prostate cancer cells CAPE induced apoptosis in adose-dependent manner that was associated with the loss ofexpression of the inhibitors of apoptosis cIAP-1 cIAP-2 andXIAP [170] Cavaliere et al [171] showed that CAPE treatment

of lymphoblastoid cell line PL104 induced apoptosis throughthe mitochondrial intrinsic pathway

It has been known that cancer microenvironment isvery important for carcinogenesis and it consists of stromalendothelial immune and cancer cells Natural productslike propolis and their constituents have been shown tointerfere with this symbiosis It was demonstrated by Lee et al[172] that CAPE could effectively suppress the adhesion andinvasion potential of human hepatocellular carcinoma cells(SK-Hep1) by inhibiting the expression ofMMP-2 andMMP-9 and NF-120581B

Angiogenesis has a crucial role in tumour growth dueto the requirement of oxygen and nutrients to sustain rapiduncontrolled proliferation and metastization Both tumourand stromal cells can secrete proangiogenic factors thatstimulate the formation andmaintenance of new vessels suchas vascular endothelial growth factor (VEGF) [173] BrazilianPEE could significantly reduce the number of newly formedvessels and suppress the proliferation of human umbilicalvein endothelial cells (HUVECs) [174] this antiangiogeniceffect being mainly mediated via inducing apoptosis in tube-forming endothelial cells through the inactivation of the sur-vival signal ERK12 [175] Yun et al [176] observed that CAPEinhibited angiogenesis using the in vivo assay chick embryochorioallantoic membrane (CAM) CAPE also suppressesVEGF formation by MDA-MB-231 cells and formation ofcapillary-like tubes by endothelial cells [162 177] Extractsof propolis containing artepillin C and CAPE significantlyreduced the newly formed vessels and expression of MMPsand VEGF production from various cells [178] and inaccordance with this study Izuta et al [179] described thatCAPE promotes inhibition of VEGF expression in HUVECcells

The first study on the antitumor activity of Portuguesepropolis was only performed in 2010 Using normal andcancerous renal cells derived from human renal cell carci-noma (RCC) patients in addition to A-498 cell line Valenteet al [64] showed that methanolic extract of Portuguesepropolis exhibited selective toxicity against malignant cellscompared to normal cells and in vitro RCC growth wasstrongly inhibited Recently our group demonstrated theantitumour and antiangiogenic activity of the ethanol extractof Pereiro propolis (P10EE) collected in the district ofGuarda Portugal P10EE affects cell viability of differenttumour cells MDA-MB-231 (breast) and DU145 (prostate)being two of the most sensitive ones but was less cytotoxicagainst nontumour cells and fibroblasts Also it signifi-cantly decreased MDA-MB-231 and DU145 cell prolifera-tion and migration along time with cell cycle changesand increased cell death The significant increase observedin glucose consumption and lactate production could beexplained in MDA-MB-231 by an increased expression ofhypoxia inducible factor-1120572 pyruvate dehydrogenase kinaseglucose transporter 1 lactate dehydrogenase and carbonicanhydrase Furthermore P10EE induced a decrease inHBMECs total biomass and proliferation and decreasedvessel sprouting in the chicken chorioallantoic membrane[23]

5 Conclusions

From ancient to modern times herbs and other plant prod-ucts have been widely used as medicinal agents first in folkmedicine and other activities in many parts of the world andlater developed and improved on a scientific basis into drugsthat are used in the health system Propolis is one of thefew natural products that has maintained its popularity overa long period of time As reviewed here propolis containsa broad spectrum of compounds that may be useful in thetreatment of different pathological conditions In fact there ismuch literature that deals with the in vitro and in vivo biologi-cal properties of propolisThis wide range of bioactivities thecontinuous discovery of new compounds the long history ofpropolis use and its safety profile make propolis a potentialcandidate for drug discovery that may be useful in severalclinical scenarios Nevertheless it is necessary to make aneffort to standardize propolis composition since it seems thatpropolis biological properties and chemical composition notonly are variable but also are strictly linked In our opinionpropolis extracts may be important economically and wouldallow a relatively inexpensive treatment in different diseaseshowever to promote its use in modern medicine it will benecessary to identify and isolate the bioactive compoundsto be tested separately or in combination with other drugsalready available

Drug discovery does not consist only of the isolationof bioactive lead compounds from the natural sources Infact this process continues outside the academic laboratoriesthrough preclinical studies followed by clinical trials Thusdespite the in vitro and in vivo assays which provide newvaluable information on propolis biological properties andmechanisms of action it will be necessary to analyse theeffectiveness of propolis clinically to complement the basicresearch available and to evaluate the potential of propolis inhuman health promotion

mechanism of CAPE H pylori a major factor for gas-trointestinal illnesses contains the enzyme H pylori peptidedeformylase that catalyses the removal of formyl group fromthe N-terminus of nascent polypeptide chains Since theaction of this enzyme is essential for H pylori survival it isconsidered a promising therapeutic drug target Results fromabsorption spectra and crystal structural characterizationshowed that CAPE is a competitive inhibitor of peptidedeformylase blocking the substrate entrance and preventingsubstrate from approaching the active site [131]

It has been suggested that the combination of propoliswith other antibiotics would allow dose reduction of selectedantibiotics thus potentiating their effect The antibacterialactivity of Italian PEE in some clinically isolated Gram-positive strains as well as the synergetic effect with someantibiotics was assessed by Scazzocchio et al [56] Ital-ian PEE drastically increased the effect of ampicillin gen-tamycin and streptomycin and moderated the action ofchloramphenicol ceftriaxone and vancomycin No effectwas observed when used simultaneously with erythromycinWojtyczka et al [132] evaluated the in vitro antimicrobialactivity of a Polish PEE against methicillin-sensitive S aureus(MSSA) and methicillin-resistant S aureus (MRSA) clinicalisolates and also the combined effect of propolis with tenselected antistaphylococcal drugs PEE displayed varyingeffectiveness against twelve S aureus strains and potentiatedthe antimicrobial effect of eight antistaphylococcal againstall tested strains No synergism was observed in the caseof ciprofloxacin and chloramphenicol In another study theeffect of dichloromethane extract of French propolis againstdifferent human pathogenic bacterial strains was also testedAlthough Gram-negative bacteria were not susceptible tothe extract a significant antibacterial activity against bothmethicillin-resistant and methicillin-susceptible S aureusstrains was observed [133] The same was confirmed byVelikova et al [28] using different PEE from BulgariaGreece Turkey and Algeria All the samples showed agood antibacterial activity against S aureus but a week orlacking effect against E coli Australian PEE from stinglessbee Tetragonula carbonaria also inhibited the growth of Saureus Nevertheless it was less active against P aeruginosa[42] The same was observed by Papachroni et al [53]using PEE from Cameroon and CongoContrary to thesestudies Katircioglu and Mercan [134] showed that TurkishPEE was effective against Gram-negative bacteria like E coliOrsi et al [135] investigated the possible synergism betweenBrazilian and Bulgarian propolis and antibiotics acting onDNA (ciprofloxacin and norfloxacin) and on metabolism(cotrimoxazole) in Salmonella typhi Both samples hadantibacterial activity but no synergistic effect was detected

Recently the suitability of nanohydroxyapatite- (nano-HA-) based surfaces containing two Brazilian PEE (greenand red ones) to prevent S aureus bacterial growth andbiofilm was studied The nanoHA impregnated with thetwo highest concentrations (12 and 25120583gmL) of red PEEshowed a remarkable reduction of 99 in the number ofviable bacteria while nanoHA with green PEE at sameconcentrations showed a reduction of 45 and 61 Moreoverthe nanoHA impregnated with the highest concentration of

red PEE was able to inhibit 80 of the staphylococcal biofilmformation [136]

Diverse studies show that as the composition of propolisvaries from region to region the antibacterial activity alsodisplays some variations [59] Susceptibility of differentGram-positive bacteria to PEE varies with the place ofpropolis collection [137] The antibacterial effect was shownto be higher for samples from a wet-tropical rain forest-type climate Other studies revealed the influence of propolisgeographical origin on its antibacterial properties [57 58 138139] Propolis from the north and centre of Portugal has agreat activity against S aureus [58 140]

452 Antifungal Activity Antifungal activity is also influ-enced by the chemical variation of propolis [59] Severalstudies have shown the effect of propolis from differentgeographic origin against different fungi particularly ofclinical interest [141ndash145] Quiroga et al [146] demonstratedthe antifungal activity of propolis from the northwest ofArgentina focusing their study on the environment andthe development of agrochemicals with reduced economiccosts possibly containing propolis extracts and its isolatedcompounds such as pinocembrin and galangin as activeprinciples

Recently Falcao et al [140] screened the antifungalactivity of Portuguese propolis and its potential floral sourcesPopulus x Canadensis and Cistus ladanifer against Candidaalbicans Trichophyton rubrum and Aspergillus fumigatusPlant extracts did not exhibit relevant antifungal activity withexception of T rubrum but both propolis samples revealedsimilar antifungal activity the highest being obtained againstT rubrum and the lowest against A fumigatus A sample ofPEE from Poland showed a high fungicidal activity againstC albicans C glabrata and C krusei [147] Recently it wasshown that different organic extracts of French propolis (PEEPWEmethanolic extract and dichloromethane extract) wereeffective against C albicans and C glabrata but only have aweak activity towards A fumigates [133]

Brazilian PEE was proved to be active against severalCandida strains (C albicans C tropicalis C krusei andC guilliermondii) C albicans being the most sensitive andC guilliermondii the most resistant [141] Brazilian greenand red propolis display activity against different fungalspecies of Trichophyton which cause dermatophytosis redPEE being more efficient than the green one [143] Also itwas shown that n-hexane extract of Brazilian red propolisdid not induce resistance in Candida spp In fact it wasactive against Candida spp resistant to antifungal agentslike fluconazole [148] Dota et al [144] evaluated the in vitroantifungal activity of PEE and propolis microparticles (PMs)obtained from a sample from Argentina against clinical yeastisolates of importance in the vulvovaginal candidiasis Calbicans and non-C albicanswere inhibited by PEE and PMswith small variation Additionally it was shown that Braziliangreen PEE has the ability to inhibit growth and biofilmformation by C albicans from vulvovaginal candidiasis [149]Another study showed fungicide action of propolis (PEEPWE propolis matricial microparticles (PMM) and propolissoluble dry extract after 6ndash8-hour treatment against all three

Evidence-Based Complementary and Alternative Medicine 17

C albicansmorphotypes (yeast pseudohyphae and hyphae)PEE being the most potent followed by PSDE PM andPWE [150] Brazilian propolis induces C albicans cell deathmediated via metacaspase since the metacaspase mutant inC albicans showed reduced sensitivity to propolis and bythe Ras pathway Using C albicans deletion libraries it waspossible to screen several mutants in genes involved eitherin the morphological transitions or in the maintenance of aspecific morphotype that are more sensitive to propolis Toconclude the study the authors also showed that propolisbased gels and cream were partially able to control vulvo-vaginal candidiasis in a mouse model [151] These studies[144] strongly indicate that propolis has a great potential tocontrol vulvovaginal candidiasis representing a promisingalternative therapeutic strategy

46 Antitumour Activity Recognition of the hallmarks ofcancer affects the search and development of new meth-ods and therapeutic agents with a sufficiently large thera-peutic window to kill tumour cells while sparing normalcells In the last years the natural product propolis hasattracted a growing interest by a large number of researcherssince it contains a variety of phytochemical compoundsthat may act through multiple pathways to reduce thedevelopment and other malignant characteristics of cancercells

Recently several in vitro studies have demonstrated acytotoxic action of propolis from different geographic originand of some of its isolated compounds on various tumourcells In vivo studies also show a potential in the developmentof new antitumor agents since propolis administration tomammals (eg rats) does not lead to detectable side effects[3] Briefly this natural product can block specific oncogenesignalling pathways which in turn lead to a decrease in cellproliferation and growth and can also act by decreasing thecancer stem cell population increasing apoptosis exertingantiangiogenic effects and modulating the tumour microen-vironment [66 152 153] Table 8 summarizes the antitumouractivity of propolis from different geographic origin and itschemical constituents

Some researchers showed the effect of different types ofpropolis and its constituents on cancer cell growth prolifera-tion and apoptosisThe hexane extract of propolis fromThai-land collected by the stingless bee Trigona laeviceps whichhas a different behavior in propolis collection compared tothe honey bees exerts antiproliferative activity against fivetested cancer cell lines (Chago KATO-III SW620 BT474and Hep-G2) but not against the normal cell lines tested(HS27 fibroblast and CH-liver) [5] A sample of PEE fromPoland inhibited human malignant melanoma (Me45) andcolorectal cancer (HCT 116) cells growth as well as reducedcell size [154]Other studies reported the antitumor activity ofBrazilianPEE [155ndash158]which regulate the protein expressionof cyclin D1 B1 and cyclin dependent kinase (CDK) as wellas p21 in human prostate cancer cells significantly affectingproliferation [158]

Although propolis containing CAPE is different fromthose with artepillin C it is possible to obtain a similarinhibitory effect from both types The effect of CAPE on

different cancer cell lines was analysed and many of itseffects have been shown to be mediated through inhibitionof NF-120581B [66 159] CAPE can inhibit the proliferation of thecolorectal cell line SW480 by decreasing the 120573-catenin c-myc and cyclin D1 protein expression [160] Chuu et al [161]observed that CAPE suppressed the proliferation of LNCaPDU-145 and PC-3 human prostate cancer cells in a dose-dependent manner and also inhibited the tumour growthof LNCaP xenografts in nude mice It was suggested that itacted through inhibition of p70S6K (an intermediary of thePI3KAKTpathway responsible for the protein synthesis) andsome Akt signalling networks Wu et al [162] demonstratedthat CAPE inhibits in vitro and in vivoMCF-7 andMDA-MB-231 tumour growthwithoutmuch effect on normalmammarycells by reducing the expression of growth and transcriptionfactors including NF-120581B Recently it was demonstrated thatCAPE effect on genes that are associated with tumour cellgrowth and survival is related in part to its role as a histonedeacetylase inhibitor [163]

As previously said propolis can also act by decreasingthe cancer stem cell population Using the putative CD44(+)CD24 (minuslow) breast cancer stem cells able to generatemammospheres from single cells Omene et al [164] showedthat CAPE caused a dose-dependent inhibition of cancerstem cells self-renewal progenitor formation and clonalgrowth

Concerning cell death some in vitro studies showeddifferent sensitivities of tumour cells to propolis extractsPWE from Iraq inhibits the proliferation of HL-60 cellsand leads to downregulation of Bcl-2 and activation of Bax[13] Alizadeh et al [165] investigated the protective effectsof Iranian PEE on N-methyl-N-nitro-N-nitrosoguanidine-(MNNG-) initiated gastric cancer in rats Results showedthat tumour incidence the number of lesions structuralabnormalities and beta-catenin of the animals group treatedwith PEE significantly declined compared with the controlPEE also induced the expression of proapoptotic Bax andreduced antiapoptotic Bcl-2 expression Propolis inhibitscolony formation potential and promotes necrotic changes inHCT-116 cells and decreases mitotic cells and increases p53and Ki-67 expression in HCT-116 tumor-bearing mice [13]Szliszkarsquos group have performed many studies to analyze theantitumour effect of different propolis and its constituentson prostate cancer cells (LNCaP and DU145) [166ndash168]Brazilian green PEE sensitized these cells to TRAIL-induceddeath enhanced the expression of TRAIL-R2 and decreasedthe activity of NF-120581B in LNCaP cells [167] Cotreatment ofTRAIL with artepillin C induced the significant activation ofcaspase-8 and caspase-3 as well as a significant disruption ofthe mitochondrial membrane potential [169] Many studieshave been conducted to understand the pathways involvedin the apoptotic effect of CAPE CAPE induces cell cyclearrest and apoptosis and reduces expression of NF-120581B inMDA-MB-231 and MCF-7 human breast cancer cells [162]In PC3 prostate cancer cells CAPE induced apoptosis in adose-dependent manner that was associated with the loss ofexpression of the inhibitors of apoptosis cIAP-1 cIAP-2 andXIAP [170] Cavaliere et al [171] showed that CAPE treatment

of lymphoblastoid cell line PL104 induced apoptosis throughthe mitochondrial intrinsic pathway

It has been known that cancer microenvironment isvery important for carcinogenesis and it consists of stromalendothelial immune and cancer cells Natural productslike propolis and their constituents have been shown tointerfere with this symbiosis It was demonstrated by Lee et al[172] that CAPE could effectively suppress the adhesion andinvasion potential of human hepatocellular carcinoma cells(SK-Hep1) by inhibiting the expression ofMMP-2 andMMP-9 and NF-120581B

Angiogenesis has a crucial role in tumour growth dueto the requirement of oxygen and nutrients to sustain rapiduncontrolled proliferation and metastization Both tumourand stromal cells can secrete proangiogenic factors thatstimulate the formation andmaintenance of new vessels suchas vascular endothelial growth factor (VEGF) [173] BrazilianPEE could significantly reduce the number of newly formedvessels and suppress the proliferation of human umbilicalvein endothelial cells (HUVECs) [174] this antiangiogeniceffect being mainly mediated via inducing apoptosis in tube-forming endothelial cells through the inactivation of the sur-vival signal ERK12 [175] Yun et al [176] observed that CAPEinhibited angiogenesis using the in vivo assay chick embryochorioallantoic membrane (CAM) CAPE also suppressesVEGF formation by MDA-MB-231 cells and formation ofcapillary-like tubes by endothelial cells [162 177] Extractsof propolis containing artepillin C and CAPE significantlyreduced the newly formed vessels and expression of MMPsand VEGF production from various cells [178] and inaccordance with this study Izuta et al [179] described thatCAPE promotes inhibition of VEGF expression in HUVECcells

The first study on the antitumor activity of Portuguesepropolis was only performed in 2010 Using normal andcancerous renal cells derived from human renal cell carci-noma (RCC) patients in addition to A-498 cell line Valenteet al [64] showed that methanolic extract of Portuguesepropolis exhibited selective toxicity against malignant cellscompared to normal cells and in vitro RCC growth wasstrongly inhibited Recently our group demonstrated theantitumour and antiangiogenic activity of the ethanol extractof Pereiro propolis (P10EE) collected in the district ofGuarda Portugal P10EE affects cell viability of differenttumour cells MDA-MB-231 (breast) and DU145 (prostate)being two of the most sensitive ones but was less cytotoxicagainst nontumour cells and fibroblasts Also it signifi-cantly decreased MDA-MB-231 and DU145 cell prolifera-tion and migration along time with cell cycle changesand increased cell death The significant increase observedin glucose consumption and lactate production could beexplained in MDA-MB-231 by an increased expression ofhypoxia inducible factor-1120572 pyruvate dehydrogenase kinaseglucose transporter 1 lactate dehydrogenase and carbonicanhydrase Furthermore P10EE induced a decrease inHBMECs total biomass and proliferation and decreasedvessel sprouting in the chicken chorioallantoic membrane[23]

5 Conclusions

From ancient to modern times herbs and other plant prod-ucts have been widely used as medicinal agents first in folkmedicine and other activities in many parts of the world andlater developed and improved on a scientific basis into drugsthat are used in the health system Propolis is one of thefew natural products that has maintained its popularity overa long period of time As reviewed here propolis containsa broad spectrum of compounds that may be useful in thetreatment of different pathological conditions In fact there ismuch literature that deals with the in vitro and in vivo biologi-cal properties of propolisThis wide range of bioactivities thecontinuous discovery of new compounds the long history ofpropolis use and its safety profile make propolis a potentialcandidate for drug discovery that may be useful in severalclinical scenarios Nevertheless it is necessary to make aneffort to standardize propolis composition since it seems thatpropolis biological properties and chemical composition notonly are variable but also are strictly linked In our opinionpropolis extracts may be important economically and wouldallow a relatively inexpensive treatment in different diseaseshowever to promote its use in modern medicine it will benecessary to identify and isolate the bioactive compoundsto be tested separately or in combination with other drugsalready available

Drug discovery does not consist only of the isolationof bioactive lead compounds from the natural sources Infact this process continues outside the academic laboratoriesthrough preclinical studies followed by clinical trials Thusdespite the in vitro and in vivo assays which provide newvaluable information on propolis biological properties andmechanisms of action it will be necessary to analyse theeffectiveness of propolis clinically to complement the basicresearch available and to evaluate the potential of propolis inhuman health promotion

mechanism of CAPE H pylori a major factor for gas-trointestinal illnesses contains the enzyme H pylori peptidedeformylase that catalyses the removal of formyl group fromthe N-terminus of nascent polypeptide chains Since theaction of this enzyme is essential for H pylori survival it isconsidered a promising therapeutic drug target Results fromabsorption spectra and crystal structural characterizationshowed that CAPE is a competitive inhibitor of peptidedeformylase blocking the substrate entrance and preventingsubstrate from approaching the active site [131]

It has been suggested that the combination of propoliswith other antibiotics would allow dose reduction of selectedantibiotics thus potentiating their effect The antibacterialactivity of Italian PEE in some clinically isolated Gram-positive strains as well as the synergetic effect with someantibiotics was assessed by Scazzocchio et al [56] Ital-ian PEE drastically increased the effect of ampicillin gen-tamycin and streptomycin and moderated the action ofchloramphenicol ceftriaxone and vancomycin No effectwas observed when used simultaneously with erythromycinWojtyczka et al [132] evaluated the in vitro antimicrobialactivity of a Polish PEE against methicillin-sensitive S aureus(MSSA) and methicillin-resistant S aureus (MRSA) clinicalisolates and also the combined effect of propolis with tenselected antistaphylococcal drugs PEE displayed varyingeffectiveness against twelve S aureus strains and potentiatedthe antimicrobial effect of eight antistaphylococcal againstall tested strains No synergism was observed in the caseof ciprofloxacin and chloramphenicol In another study theeffect of dichloromethane extract of French propolis againstdifferent human pathogenic bacterial strains was also testedAlthough Gram-negative bacteria were not susceptible tothe extract a significant antibacterial activity against bothmethicillin-resistant and methicillin-susceptible S aureusstrains was observed [133] The same was confirmed byVelikova et al [28] using different PEE from BulgariaGreece Turkey and Algeria All the samples showed agood antibacterial activity against S aureus but a week orlacking effect against E coli Australian PEE from stinglessbee Tetragonula carbonaria also inhibited the growth of Saureus Nevertheless it was less active against P aeruginosa[42] The same was observed by Papachroni et al [53]using PEE from Cameroon and CongoContrary to thesestudies Katircioglu and Mercan [134] showed that TurkishPEE was effective against Gram-negative bacteria like E coliOrsi et al [135] investigated the possible synergism betweenBrazilian and Bulgarian propolis and antibiotics acting onDNA (ciprofloxacin and norfloxacin) and on metabolism(cotrimoxazole) in Salmonella typhi Both samples hadantibacterial activity but no synergistic effect was detected

Recently the suitability of nanohydroxyapatite- (nano-HA-) based surfaces containing two Brazilian PEE (greenand red ones) to prevent S aureus bacterial growth andbiofilm was studied The nanoHA impregnated with thetwo highest concentrations (12 and 25120583gmL) of red PEEshowed a remarkable reduction of 99 in the number ofviable bacteria while nanoHA with green PEE at sameconcentrations showed a reduction of 45 and 61 Moreoverthe nanoHA impregnated with the highest concentration of

red PEE was able to inhibit 80 of the staphylococcal biofilmformation [136]

Diverse studies show that as the composition of propolisvaries from region to region the antibacterial activity alsodisplays some variations [59] Susceptibility of differentGram-positive bacteria to PEE varies with the place ofpropolis collection [137] The antibacterial effect was shownto be higher for samples from a wet-tropical rain forest-type climate Other studies revealed the influence of propolisgeographical origin on its antibacterial properties [57 58 138139] Propolis from the north and centre of Portugal has agreat activity against S aureus [58 140]

452 Antifungal Activity Antifungal activity is also influ-enced by the chemical variation of propolis [59] Severalstudies have shown the effect of propolis from differentgeographic origin against different fungi particularly ofclinical interest [141ndash145] Quiroga et al [146] demonstratedthe antifungal activity of propolis from the northwest ofArgentina focusing their study on the environment andthe development of agrochemicals with reduced economiccosts possibly containing propolis extracts and its isolatedcompounds such as pinocembrin and galangin as activeprinciples

Recently Falcao et al [140] screened the antifungalactivity of Portuguese propolis and its potential floral sourcesPopulus x Canadensis and Cistus ladanifer against Candidaalbicans Trichophyton rubrum and Aspergillus fumigatusPlant extracts did not exhibit relevant antifungal activity withexception of T rubrum but both propolis samples revealedsimilar antifungal activity the highest being obtained againstT rubrum and the lowest against A fumigatus A sample ofPEE from Poland showed a high fungicidal activity againstC albicans C glabrata and C krusei [147] Recently it wasshown that different organic extracts of French propolis (PEEPWEmethanolic extract and dichloromethane extract) wereeffective against C albicans and C glabrata but only have aweak activity towards A fumigates [133]

Brazilian PEE was proved to be active against severalCandida strains (C albicans C tropicalis C krusei andC guilliermondii) C albicans being the most sensitive andC guilliermondii the most resistant [141] Brazilian greenand red propolis display activity against different fungalspecies of Trichophyton which cause dermatophytosis redPEE being more efficient than the green one [143] Also itwas shown that n-hexane extract of Brazilian red propolisdid not induce resistance in Candida spp In fact it wasactive against Candida spp resistant to antifungal agentslike fluconazole [148] Dota et al [144] evaluated the in vitroantifungal activity of PEE and propolis microparticles (PMs)obtained from a sample from Argentina against clinical yeastisolates of importance in the vulvovaginal candidiasis Calbicans and non-C albicanswere inhibited by PEE and PMswith small variation Additionally it was shown that Braziliangreen PEE has the ability to inhibit growth and biofilmformation by C albicans from vulvovaginal candidiasis [149]Another study showed fungicide action of propolis (PEEPWE propolis matricial microparticles (PMM) and propolissoluble dry extract after 6ndash8-hour treatment against all three

C albicansmorphotypes (yeast pseudohyphae and hyphae)PEE being the most potent followed by PSDE PM andPWE [150] Brazilian propolis induces C albicans cell deathmediated via metacaspase since the metacaspase mutant inC albicans showed reduced sensitivity to propolis and bythe Ras pathway Using C albicans deletion libraries it waspossible to screen several mutants in genes involved eitherin the morphological transitions or in the maintenance of aspecific morphotype that are more sensitive to propolis Toconclude the study the authors also showed that propolisbased gels and cream were partially able to control vulvo-vaginal candidiasis in a mouse model [151] These studies[144] strongly indicate that propolis has a great potential tocontrol vulvovaginal candidiasis representing a promisingalternative therapeutic strategy

46 Antitumour Activity Recognition of the hallmarks ofcancer affects the search and development of new meth-ods and therapeutic agents with a sufficiently large thera-peutic window to kill tumour cells while sparing normalcells In the last years the natural product propolis hasattracted a growing interest by a large number of researcherssince it contains a variety of phytochemical compoundsthat may act through multiple pathways to reduce thedevelopment and other malignant characteristics of cancercells

Recently several in vitro studies have demonstrated acytotoxic action of propolis from different geographic originand of some of its isolated compounds on various tumourcells In vivo studies also show a potential in the developmentof new antitumor agents since propolis administration tomammals (eg rats) does not lead to detectable side effects[3] Briefly this natural product can block specific oncogenesignalling pathways which in turn lead to a decrease in cellproliferation and growth and can also act by decreasing thecancer stem cell population increasing apoptosis exertingantiangiogenic effects and modulating the tumour microen-vironment [66 152 153] Table 8 summarizes the antitumouractivity of propolis from different geographic origin and itschemical constituents

Some researchers showed the effect of different types ofpropolis and its constituents on cancer cell growth prolifera-tion and apoptosisThe hexane extract of propolis fromThai-land collected by the stingless bee Trigona laeviceps whichhas a different behavior in propolis collection compared tothe honey bees exerts antiproliferative activity against fivetested cancer cell lines (Chago KATO-III SW620 BT474and Hep-G2) but not against the normal cell lines tested(HS27 fibroblast and CH-liver) [5] A sample of PEE fromPoland inhibited human malignant melanoma (Me45) andcolorectal cancer (HCT 116) cells growth as well as reducedcell size [154]Other studies reported the antitumor activity ofBrazilianPEE [155ndash158]which regulate the protein expressionof cyclin D1 B1 and cyclin dependent kinase (CDK) as wellas p21 in human prostate cancer cells significantly affectingproliferation [158]

Although propolis containing CAPE is different fromthose with artepillin C it is possible to obtain a similarinhibitory effect from both types The effect of CAPE on

different cancer cell lines was analysed and many of itseffects have been shown to be mediated through inhibitionof NF-120581B [66 159] CAPE can inhibit the proliferation of thecolorectal cell line SW480 by decreasing the 120573-catenin c-myc and cyclin D1 protein expression [160] Chuu et al [161]observed that CAPE suppressed the proliferation of LNCaPDU-145 and PC-3 human prostate cancer cells in a dose-dependent manner and also inhibited the tumour growthof LNCaP xenografts in nude mice It was suggested that itacted through inhibition of p70S6K (an intermediary of thePI3KAKTpathway responsible for the protein synthesis) andsome Akt signalling networks Wu et al [162] demonstratedthat CAPE inhibits in vitro and in vivoMCF-7 andMDA-MB-231 tumour growthwithoutmuch effect on normalmammarycells by reducing the expression of growth and transcriptionfactors including NF-120581B Recently it was demonstrated thatCAPE effect on genes that are associated with tumour cellgrowth and survival is related in part to its role as a histonedeacetylase inhibitor [163]

As previously said propolis can also act by decreasingthe cancer stem cell population Using the putative CD44(+)CD24 (minuslow) breast cancer stem cells able to generatemammospheres from single cells Omene et al [164] showedthat CAPE caused a dose-dependent inhibition of cancerstem cells self-renewal progenitor formation and clonalgrowth

Concerning cell death some in vitro studies showeddifferent sensitivities of tumour cells to propolis extractsPWE from Iraq inhibits the proliferation of HL-60 cellsand leads to downregulation of Bcl-2 and activation of Bax[13] Alizadeh et al [165] investigated the protective effectsof Iranian PEE on N-methyl-N-nitro-N-nitrosoguanidine-(MNNG-) initiated gastric cancer in rats Results showedthat tumour incidence the number of lesions structuralabnormalities and beta-catenin of the animals group treatedwith PEE significantly declined compared with the controlPEE also induced the expression of proapoptotic Bax andreduced antiapoptotic Bcl-2 expression Propolis inhibitscolony formation potential and promotes necrotic changes inHCT-116 cells and decreases mitotic cells and increases p53and Ki-67 expression in HCT-116 tumor-bearing mice [13]Szliszkarsquos group have performed many studies to analyze theantitumour effect of different propolis and its constituentson prostate cancer cells (LNCaP and DU145) [166ndash168]Brazilian green PEE sensitized these cells to TRAIL-induceddeath enhanced the expression of TRAIL-R2 and decreasedthe activity of NF-120581B in LNCaP cells [167] Cotreatment ofTRAIL with artepillin C induced the significant activation ofcaspase-8 and caspase-3 as well as a significant disruption ofthe mitochondrial membrane potential [169] Many studieshave been conducted to understand the pathways involvedin the apoptotic effect of CAPE CAPE induces cell cyclearrest and apoptosis and reduces expression of NF-120581B inMDA-MB-231 and MCF-7 human breast cancer cells [162]In PC3 prostate cancer cells CAPE induced apoptosis in adose-dependent manner that was associated with the loss ofexpression of the inhibitors of apoptosis cIAP-1 cIAP-2 andXIAP [170] Cavaliere et al [171] showed that CAPE treatment

of lymphoblastoid cell line PL104 induced apoptosis throughthe mitochondrial intrinsic pathway

It has been known that cancer microenvironment isvery important for carcinogenesis and it consists of stromalendothelial immune and cancer cells Natural productslike propolis and their constituents have been shown tointerfere with this symbiosis It was demonstrated by Lee et al[172] that CAPE could effectively suppress the adhesion andinvasion potential of human hepatocellular carcinoma cells(SK-Hep1) by inhibiting the expression ofMMP-2 andMMP-9 and NF-120581B

Angiogenesis has a crucial role in tumour growth dueto the requirement of oxygen and nutrients to sustain rapiduncontrolled proliferation and metastization Both tumourand stromal cells can secrete proangiogenic factors thatstimulate the formation andmaintenance of new vessels suchas vascular endothelial growth factor (VEGF) [173] BrazilianPEE could significantly reduce the number of newly formedvessels and suppress the proliferation of human umbilicalvein endothelial cells (HUVECs) [174] this antiangiogeniceffect being mainly mediated via inducing apoptosis in tube-forming endothelial cells through the inactivation of the sur-vival signal ERK12 [175] Yun et al [176] observed that CAPEinhibited angiogenesis using the in vivo assay chick embryochorioallantoic membrane (CAM) CAPE also suppressesVEGF formation by MDA-MB-231 cells and formation ofcapillary-like tubes by endothelial cells [162 177] Extractsof propolis containing artepillin C and CAPE significantlyreduced the newly formed vessels and expression of MMPsand VEGF production from various cells [178] and inaccordance with this study Izuta et al [179] described thatCAPE promotes inhibition of VEGF expression in HUVECcells

The first study on the antitumor activity of Portuguesepropolis was only performed in 2010 Using normal andcancerous renal cells derived from human renal cell carci-noma (RCC) patients in addition to A-498 cell line Valenteet al [64] showed that methanolic extract of Portuguesepropolis exhibited selective toxicity against malignant cellscompared to normal cells and in vitro RCC growth wasstrongly inhibited Recently our group demonstrated theantitumour and antiangiogenic activity of the ethanol extractof Pereiro propolis (P10EE) collected in the district ofGuarda Portugal P10EE affects cell viability of differenttumour cells MDA-MB-231 (breast) and DU145 (prostate)being two of the most sensitive ones but was less cytotoxicagainst nontumour cells and fibroblasts Also it signifi-cantly decreased MDA-MB-231 and DU145 cell prolifera-tion and migration along time with cell cycle changesand increased cell death The significant increase observedin glucose consumption and lactate production could beexplained in MDA-MB-231 by an increased expression ofhypoxia inducible factor-1120572 pyruvate dehydrogenase kinaseglucose transporter 1 lactate dehydrogenase and carbonicanhydrase Furthermore P10EE induced a decrease inHBMECs total biomass and proliferation and decreasedvessel sprouting in the chicken chorioallantoic membrane[23]

5 Conclusions

From ancient to modern times herbs and other plant prod-ucts have been widely used as medicinal agents first in folkmedicine and other activities in many parts of the world andlater developed and improved on a scientific basis into drugsthat are used in the health system Propolis is one of thefew natural products that has maintained its popularity overa long period of time As reviewed here propolis containsa broad spectrum of compounds that may be useful in thetreatment of different pathological conditions In fact there ismuch literature that deals with the in vitro and in vivo biologi-cal properties of propolisThis wide range of bioactivities thecontinuous discovery of new compounds the long history ofpropolis use and its safety profile make propolis a potentialcandidate for drug discovery that may be useful in severalclinical scenarios Nevertheless it is necessary to make aneffort to standardize propolis composition since it seems thatpropolis biological properties and chemical composition notonly are variable but also are strictly linked In our opinionpropolis extracts may be important economically and wouldallow a relatively inexpensive treatment in different diseaseshowever to promote its use in modern medicine it will benecessary to identify and isolate the bioactive compoundsto be tested separately or in combination with other drugsalready available

Drug discovery does not consist only of the isolationof bioactive lead compounds from the natural sources Infact this process continues outside the academic laboratoriesthrough preclinical studies followed by clinical trials Thusdespite the in vitro and in vivo assays which provide newvaluable information on propolis biological properties andmechanisms of action it will be necessary to analyse theeffectiveness of propolis clinically to complement the basicresearch available and to evaluate the potential of propolis inhuman health promotion

mechanism of CAPE H pylori a major factor for gas-trointestinal illnesses contains the enzyme H pylori peptidedeformylase that catalyses the removal of formyl group fromthe N-terminus of nascent polypeptide chains Since theaction of this enzyme is essential for H pylori survival it isconsidered a promising therapeutic drug target Results fromabsorption spectra and crystal structural characterizationshowed that CAPE is a competitive inhibitor of peptidedeformylase blocking the substrate entrance and preventingsubstrate from approaching the active site [131]

It has been suggested that the combination of propoliswith other antibiotics would allow dose reduction of selectedantibiotics thus potentiating their effect The antibacterialactivity of Italian PEE in some clinically isolated Gram-positive strains as well as the synergetic effect with someantibiotics was assessed by Scazzocchio et al [56] Ital-ian PEE drastically increased the effect of ampicillin gen-tamycin and streptomycin and moderated the action ofchloramphenicol ceftriaxone and vancomycin No effectwas observed when used simultaneously with erythromycinWojtyczka et al [132] evaluated the in vitro antimicrobialactivity of a Polish PEE against methicillin-sensitive S aureus(MSSA) and methicillin-resistant S aureus (MRSA) clinicalisolates and also the combined effect of propolis with tenselected antistaphylococcal drugs PEE displayed varyingeffectiveness against twelve S aureus strains and potentiatedthe antimicrobial effect of eight antistaphylococcal againstall tested strains No synergism was observed in the caseof ciprofloxacin and chloramphenicol In another study theeffect of dichloromethane extract of French propolis againstdifferent human pathogenic bacterial strains was also testedAlthough Gram-negative bacteria were not susceptible tothe extract a significant antibacterial activity against bothmethicillin-resistant and methicillin-susceptible S aureusstrains was observed [133] The same was confirmed byVelikova et al [28] using different PEE from BulgariaGreece Turkey and Algeria All the samples showed agood antibacterial activity against S aureus but a week orlacking effect against E coli Australian PEE from stinglessbee Tetragonula carbonaria also inhibited the growth of Saureus Nevertheless it was less active against P aeruginosa[42] The same was observed by Papachroni et al [53]using PEE from Cameroon and CongoContrary to thesestudies Katircioglu and Mercan [134] showed that TurkishPEE was effective against Gram-negative bacteria like E coliOrsi et al [135] investigated the possible synergism betweenBrazilian and Bulgarian propolis and antibiotics acting onDNA (ciprofloxacin and norfloxacin) and on metabolism(cotrimoxazole) in Salmonella typhi Both samples hadantibacterial activity but no synergistic effect was detected

Recently the suitability of nanohydroxyapatite- (nano-HA-) based surfaces containing two Brazilian PEE (greenand red ones) to prevent S aureus bacterial growth andbiofilm was studied The nanoHA impregnated with thetwo highest concentrations (12 and 25120583gmL) of red PEEshowed a remarkable reduction of 99 in the number ofviable bacteria while nanoHA with green PEE at sameconcentrations showed a reduction of 45 and 61 Moreoverthe nanoHA impregnated with the highest concentration of

red PEE was able to inhibit 80 of the staphylococcal biofilmformation [136]

Diverse studies show that as the composition of propolisvaries from region to region the antibacterial activity alsodisplays some variations [59] Susceptibility of differentGram-positive bacteria to PEE varies with the place ofpropolis collection [137] The antibacterial effect was shownto be higher for samples from a wet-tropical rain forest-type climate Other studies revealed the influence of propolisgeographical origin on its antibacterial properties [57 58 138139] Propolis from the north and centre of Portugal has agreat activity against S aureus [58 140]

452 Antifungal Activity Antifungal activity is also influ-enced by the chemical variation of propolis [59] Severalstudies have shown the effect of propolis from differentgeographic origin against different fungi particularly ofclinical interest [141ndash145] Quiroga et al [146] demonstratedthe antifungal activity of propolis from the northwest ofArgentina focusing their study on the environment andthe development of agrochemicals with reduced economiccosts possibly containing propolis extracts and its isolatedcompounds such as pinocembrin and galangin as activeprinciples

Recently Falcao et al [140] screened the antifungalactivity of Portuguese propolis and its potential floral sourcesPopulus x Canadensis and Cistus ladanifer against Candidaalbicans Trichophyton rubrum and Aspergillus fumigatusPlant extracts did not exhibit relevant antifungal activity withexception of T rubrum but both propolis samples revealedsimilar antifungal activity the highest being obtained againstT rubrum and the lowest against A fumigatus A sample ofPEE from Poland showed a high fungicidal activity againstC albicans C glabrata and C krusei [147] Recently it wasshown that different organic extracts of French propolis (PEEPWEmethanolic extract and dichloromethane extract) wereeffective against C albicans and C glabrata but only have aweak activity towards A fumigates [133]

Brazilian PEE was proved to be active against severalCandida strains (C albicans C tropicalis C krusei andC guilliermondii) C albicans being the most sensitive andC guilliermondii the most resistant [141] Brazilian greenand red propolis display activity against different fungalspecies of Trichophyton which cause dermatophytosis redPEE being more efficient than the green one [143] Also itwas shown that n-hexane extract of Brazilian red propolisdid not induce resistance in Candida spp In fact it wasactive against Candida spp resistant to antifungal agentslike fluconazole [148] Dota et al [144] evaluated the in vitroantifungal activity of PEE and propolis microparticles (PMs)obtained from a sample from Argentina against clinical yeastisolates of importance in the vulvovaginal candidiasis Calbicans and non-C albicanswere inhibited by PEE and PMswith small variation Additionally it was shown that Braziliangreen PEE has the ability to inhibit growth and biofilmformation by C albicans from vulvovaginal candidiasis [149]Another study showed fungicide action of propolis (PEEPWE propolis matricial microparticles (PMM) and propolissoluble dry extract after 6ndash8-hour treatment against all three

C albicansmorphotypes (yeast pseudohyphae and hyphae)PEE being the most potent followed by PSDE PM andPWE [150] Brazilian propolis induces C albicans cell deathmediated via metacaspase since the metacaspase mutant inC albicans showed reduced sensitivity to propolis and bythe Ras pathway Using C albicans deletion libraries it waspossible to screen several mutants in genes involved eitherin the morphological transitions or in the maintenance of aspecific morphotype that are more sensitive to propolis Toconclude the study the authors also showed that propolisbased gels and cream were partially able to control vulvo-vaginal candidiasis in a mouse model [151] These studies[144] strongly indicate that propolis has a great potential tocontrol vulvovaginal candidiasis representing a promisingalternative therapeutic strategy

46 Antitumour Activity Recognition of the hallmarks ofcancer affects the search and development of new meth-ods and therapeutic agents with a sufficiently large thera-peutic window to kill tumour cells while sparing normalcells In the last years the natural product propolis hasattracted a growing interest by a large number of researcherssince it contains a variety of phytochemical compoundsthat may act through multiple pathways to reduce thedevelopment and other malignant characteristics of cancercells

Recently several in vitro studies have demonstrated acytotoxic action of propolis from different geographic originand of some of its isolated compounds on various tumourcells In vivo studies also show a potential in the developmentof new antitumor agents since propolis administration tomammals (eg rats) does not lead to detectable side effects[3] Briefly this natural product can block specific oncogenesignalling pathways which in turn lead to a decrease in cellproliferation and growth and can also act by decreasing thecancer stem cell population increasing apoptosis exertingantiangiogenic effects and modulating the tumour microen-vironment [66 152 153] Table 8 summarizes the antitumouractivity of propolis from different geographic origin and itschemical constituents

Some researchers showed the effect of different types ofpropolis and its constituents on cancer cell growth prolifera-tion and apoptosisThe hexane extract of propolis fromThai-land collected by the stingless bee Trigona laeviceps whichhas a different behavior in propolis collection compared tothe honey bees exerts antiproliferative activity against fivetested cancer cell lines (Chago KATO-III SW620 BT474and Hep-G2) but not against the normal cell lines tested(HS27 fibroblast and CH-liver) [5] A sample of PEE fromPoland inhibited human malignant melanoma (Me45) andcolorectal cancer (HCT 116) cells growth as well as reducedcell size [154]Other studies reported the antitumor activity ofBrazilianPEE [155ndash158]which regulate the protein expressionof cyclin D1 B1 and cyclin dependent kinase (CDK) as wellas p21 in human prostate cancer cells significantly affectingproliferation [158]

Although propolis containing CAPE is different fromthose with artepillin C it is possible to obtain a similarinhibitory effect from both types The effect of CAPE on

different cancer cell lines was analysed and many of itseffects have been shown to be mediated through inhibitionof NF-120581B [66 159] CAPE can inhibit the proliferation of thecolorectal cell line SW480 by decreasing the 120573-catenin c-myc and cyclin D1 protein expression [160] Chuu et al [161]observed that CAPE suppressed the proliferation of LNCaPDU-145 and PC-3 human prostate cancer cells in a dose-dependent manner and also inhibited the tumour growthof LNCaP xenografts in nude mice It was suggested that itacted through inhibition of p70S6K (an intermediary of thePI3KAKTpathway responsible for the protein synthesis) andsome Akt signalling networks Wu et al [162] demonstratedthat CAPE inhibits in vitro and in vivoMCF-7 andMDA-MB-231 tumour growthwithoutmuch effect on normalmammarycells by reducing the expression of growth and transcriptionfactors including NF-120581B Recently it was demonstrated thatCAPE effect on genes that are associated with tumour cellgrowth and survival is related in part to its role as a histonedeacetylase inhibitor [163]

As previously said propolis can also act by decreasingthe cancer stem cell population Using the putative CD44(+)CD24 (minuslow) breast cancer stem cells able to generatemammospheres from single cells Omene et al [164] showedthat CAPE caused a dose-dependent inhibition of cancerstem cells self-renewal progenitor formation and clonalgrowth

Concerning cell death some in vitro studies showeddifferent sensitivities of tumour cells to propolis extractsPWE from Iraq inhibits the proliferation of HL-60 cellsand leads to downregulation of Bcl-2 and activation of Bax[13] Alizadeh et al [165] investigated the protective effectsof Iranian PEE on N-methyl-N-nitro-N-nitrosoguanidine-(MNNG-) initiated gastric cancer in rats Results showedthat tumour incidence the number of lesions structuralabnormalities and beta-catenin of the animals group treatedwith PEE significantly declined compared with the controlPEE also induced the expression of proapoptotic Bax andreduced antiapoptotic Bcl-2 expression Propolis inhibitscolony formation potential and promotes necrotic changes inHCT-116 cells and decreases mitotic cells and increases p53and Ki-67 expression in HCT-116 tumor-bearing mice [13]Szliszkarsquos group have performed many studies to analyze theantitumour effect of different propolis and its constituentson prostate cancer cells (LNCaP and DU145) [166ndash168]Brazilian green PEE sensitized these cells to TRAIL-induceddeath enhanced the expression of TRAIL-R2 and decreasedthe activity of NF-120581B in LNCaP cells [167] Cotreatment ofTRAIL with artepillin C induced the significant activation ofcaspase-8 and caspase-3 as well as a significant disruption ofthe mitochondrial membrane potential [169] Many studieshave been conducted to understand the pathways involvedin the apoptotic effect of CAPE CAPE induces cell cyclearrest and apoptosis and reduces expression of NF-120581B inMDA-MB-231 and MCF-7 human breast cancer cells [162]In PC3 prostate cancer cells CAPE induced apoptosis in adose-dependent manner that was associated with the loss ofexpression of the inhibitors of apoptosis cIAP-1 cIAP-2 andXIAP [170] Cavaliere et al [171] showed that CAPE treatment

of lymphoblastoid cell line PL104 induced apoptosis throughthe mitochondrial intrinsic pathway

It has been known that cancer microenvironment isvery important for carcinogenesis and it consists of stromalendothelial immune and cancer cells Natural productslike propolis and their constituents have been shown tointerfere with this symbiosis It was demonstrated by Lee et al[172] that CAPE could effectively suppress the adhesion andinvasion potential of human hepatocellular carcinoma cells(SK-Hep1) by inhibiting the expression ofMMP-2 andMMP-9 and NF-120581B

Angiogenesis has a crucial role in tumour growth dueto the requirement of oxygen and nutrients to sustain rapiduncontrolled proliferation and metastization Both tumourand stromal cells can secrete proangiogenic factors thatstimulate the formation andmaintenance of new vessels suchas vascular endothelial growth factor (VEGF) [173] BrazilianPEE could significantly reduce the number of newly formedvessels and suppress the proliferation of human umbilicalvein endothelial cells (HUVECs) [174] this antiangiogeniceffect being mainly mediated via inducing apoptosis in tube-forming endothelial cells through the inactivation of the sur-vival signal ERK12 [175] Yun et al [176] observed that CAPEinhibited angiogenesis using the in vivo assay chick embryochorioallantoic membrane (CAM) CAPE also suppressesVEGF formation by MDA-MB-231 cells and formation ofcapillary-like tubes by endothelial cells [162 177] Extractsof propolis containing artepillin C and CAPE significantlyreduced the newly formed vessels and expression of MMPsand VEGF production from various cells [178] and inaccordance with this study Izuta et al [179] described thatCAPE promotes inhibition of VEGF expression in HUVECcells

The first study on the antitumor activity of Portuguesepropolis was only performed in 2010 Using normal andcancerous renal cells derived from human renal cell carci-noma (RCC) patients in addition to A-498 cell line Valenteet al [64] showed that methanolic extract of Portuguesepropolis exhibited selective toxicity against malignant cellscompared to normal cells and in vitro RCC growth wasstrongly inhibited Recently our group demonstrated theantitumour and antiangiogenic activity of the ethanol extractof Pereiro propolis (P10EE) collected in the district ofGuarda Portugal P10EE affects cell viability of differenttumour cells MDA-MB-231 (breast) and DU145 (prostate)being two of the most sensitive ones but was less cytotoxicagainst nontumour cells and fibroblasts Also it signifi-cantly decreased MDA-MB-231 and DU145 cell prolifera-tion and migration along time with cell cycle changesand increased cell death The significant increase observedin glucose consumption and lactate production could beexplained in MDA-MB-231 by an increased expression ofhypoxia inducible factor-1120572 pyruvate dehydrogenase kinaseglucose transporter 1 lactate dehydrogenase and carbonicanhydrase Furthermore P10EE induced a decrease inHBMECs total biomass and proliferation and decreasedvessel sprouting in the chicken chorioallantoic membrane[23]

5 Conclusions

From ancient to modern times herbs and other plant prod-ucts have been widely used as medicinal agents first in folkmedicine and other activities in many parts of the world andlater developed and improved on a scientific basis into drugsthat are used in the health system Propolis is one of thefew natural products that has maintained its popularity overa long period of time As reviewed here propolis containsa broad spectrum of compounds that may be useful in thetreatment of different pathological conditions In fact there ismuch literature that deals with the in vitro and in vivo biologi-cal properties of propolisThis wide range of bioactivities thecontinuous discovery of new compounds the long history ofpropolis use and its safety profile make propolis a potentialcandidate for drug discovery that may be useful in severalclinical scenarios Nevertheless it is necessary to make aneffort to standardize propolis composition since it seems thatpropolis biological properties and chemical composition notonly are variable but also are strictly linked In our opinionpropolis extracts may be important economically and wouldallow a relatively inexpensive treatment in different diseaseshowever to promote its use in modern medicine it will benecessary to identify and isolate the bioactive compoundsto be tested separately or in combination with other drugsalready available

Drug discovery does not consist only of the isolationof bioactive lead compounds from the natural sources Infact this process continues outside the academic laboratoriesthrough preclinical studies followed by clinical trials Thusdespite the in vitro and in vivo assays which provide newvaluable information on propolis biological properties andmechanisms of action it will be necessary to analyse theeffectiveness of propolis clinically to complement the basicresearch available and to evaluate the potential of propolis inhuman health promotion

mechanism of CAPE H pylori a major factor for gas-trointestinal illnesses contains the enzyme H pylori peptidedeformylase that catalyses the removal of formyl group fromthe N-terminus of nascent polypeptide chains Since theaction of this enzyme is essential for H pylori survival it isconsidered a promising therapeutic drug target Results fromabsorption spectra and crystal structural characterizationshowed that CAPE is a competitive inhibitor of peptidedeformylase blocking the substrate entrance and preventingsubstrate from approaching the active site [131]

It has been suggested that the combination of propoliswith other antibiotics would allow dose reduction of selectedantibiotics thus potentiating their effect The antibacterialactivity of Italian PEE in some clinically isolated Gram-positive strains as well as the synergetic effect with someantibiotics was assessed by Scazzocchio et al [56] Ital-ian PEE drastically increased the effect of ampicillin gen-tamycin and streptomycin and moderated the action ofchloramphenicol ceftriaxone and vancomycin No effectwas observed when used simultaneously with erythromycinWojtyczka et al [132] evaluated the in vitro antimicrobialactivity of a Polish PEE against methicillin-sensitive S aureus(MSSA) and methicillin-resistant S aureus (MRSA) clinicalisolates and also the combined effect of propolis with tenselected antistaphylococcal drugs PEE displayed varyingeffectiveness against twelve S aureus strains and potentiatedthe antimicrobial effect of eight antistaphylococcal againstall tested strains No synergism was observed in the caseof ciprofloxacin and chloramphenicol In another study theeffect of dichloromethane extract of French propolis againstdifferent human pathogenic bacterial strains was also testedAlthough Gram-negative bacteria were not susceptible tothe extract a significant antibacterial activity against bothmethicillin-resistant and methicillin-susceptible S aureusstrains was observed [133] The same was confirmed byVelikova et al [28] using different PEE from BulgariaGreece Turkey and Algeria All the samples showed agood antibacterial activity against S aureus but a week orlacking effect against E coli Australian PEE from stinglessbee Tetragonula carbonaria also inhibited the growth of Saureus Nevertheless it was less active against P aeruginosa[42] The same was observed by Papachroni et al [53]using PEE from Cameroon and CongoContrary to thesestudies Katircioglu and Mercan [134] showed that TurkishPEE was effective against Gram-negative bacteria like E coliOrsi et al [135] investigated the possible synergism betweenBrazilian and Bulgarian propolis and antibiotics acting onDNA (ciprofloxacin and norfloxacin) and on metabolism(cotrimoxazole) in Salmonella typhi Both samples hadantibacterial activity but no synergistic effect was detected

Recently the suitability of nanohydroxyapatite- (nano-HA-) based surfaces containing two Brazilian PEE (greenand red ones) to prevent S aureus bacterial growth andbiofilm was studied The nanoHA impregnated with thetwo highest concentrations (12 and 25120583gmL) of red PEEshowed a remarkable reduction of 99 in the number ofviable bacteria while nanoHA with green PEE at sameconcentrations showed a reduction of 45 and 61 Moreoverthe nanoHA impregnated with the highest concentration of

red PEE was able to inhibit 80 of the staphylococcal biofilmformation [136]

Diverse studies show that as the composition of propolisvaries from region to region the antibacterial activity alsodisplays some variations [59] Susceptibility of differentGram-positive bacteria to PEE varies with the place ofpropolis collection [137] The antibacterial effect was shownto be higher for samples from a wet-tropical rain forest-type climate Other studies revealed the influence of propolisgeographical origin on its antibacterial properties [57 58 138139] Propolis from the north and centre of Portugal has agreat activity against S aureus [58 140]

452 Antifungal Activity Antifungal activity is also influ-enced by the chemical variation of propolis [59] Severalstudies have shown the effect of propolis from differentgeographic origin against different fungi particularly ofclinical interest [141ndash145] Quiroga et al [146] demonstratedthe antifungal activity of propolis from the northwest ofArgentina focusing their study on the environment andthe development of agrochemicals with reduced economiccosts possibly containing propolis extracts and its isolatedcompounds such as pinocembrin and galangin as activeprinciples

Recently Falcao et al [140] screened the antifungalactivity of Portuguese propolis and its potential floral sourcesPopulus x Canadensis and Cistus ladanifer against Candidaalbicans Trichophyton rubrum and Aspergillus fumigatusPlant extracts did not exhibit relevant antifungal activity withexception of T rubrum but both propolis samples revealedsimilar antifungal activity the highest being obtained againstT rubrum and the lowest against A fumigatus A sample ofPEE from Poland showed a high fungicidal activity againstC albicans C glabrata and C krusei [147] Recently it wasshown that different organic extracts of French propolis (PEEPWEmethanolic extract and dichloromethane extract) wereeffective against C albicans and C glabrata but only have aweak activity towards A fumigates [133]

Brazilian PEE was proved to be active against severalCandida strains (C albicans C tropicalis C krusei andC guilliermondii) C albicans being the most sensitive andC guilliermondii the most resistant [141] Brazilian greenand red propolis display activity against different fungalspecies of Trichophyton which cause dermatophytosis redPEE being more efficient than the green one [143] Also itwas shown that n-hexane extract of Brazilian red propolisdid not induce resistance in Candida spp In fact it wasactive against Candida spp resistant to antifungal agentslike fluconazole [148] Dota et al [144] evaluated the in vitroantifungal activity of PEE and propolis microparticles (PMs)obtained from a sample from Argentina against clinical yeastisolates of importance in the vulvovaginal candidiasis Calbicans and non-C albicanswere inhibited by PEE and PMswith small variation Additionally it was shown that Braziliangreen PEE has the ability to inhibit growth and biofilmformation by C albicans from vulvovaginal candidiasis [149]Another study showed fungicide action of propolis (PEEPWE propolis matricial microparticles (PMM) and propolissoluble dry extract after 6ndash8-hour treatment against all three

C albicansmorphotypes (yeast pseudohyphae and hyphae)PEE being the most potent followed by PSDE PM andPWE [150] Brazilian propolis induces C albicans cell deathmediated via metacaspase since the metacaspase mutant inC albicans showed reduced sensitivity to propolis and bythe Ras pathway Using C albicans deletion libraries it waspossible to screen several mutants in genes involved eitherin the morphological transitions or in the maintenance of aspecific morphotype that are more sensitive to propolis Toconclude the study the authors also showed that propolisbased gels and cream were partially able to control vulvo-vaginal candidiasis in a mouse model [151] These studies[144] strongly indicate that propolis has a great potential tocontrol vulvovaginal candidiasis representing a promisingalternative therapeutic strategy

46 Antitumour Activity Recognition of the hallmarks ofcancer affects the search and development of new meth-ods and therapeutic agents with a sufficiently large thera-peutic window to kill tumour cells while sparing normalcells In the last years the natural product propolis hasattracted a growing interest by a large number of researcherssince it contains a variety of phytochemical compoundsthat may act through multiple pathways to reduce thedevelopment and other malignant characteristics of cancercells

Recently several in vitro studies have demonstrated acytotoxic action of propolis from different geographic originand of some of its isolated compounds on various tumourcells In vivo studies also show a potential in the developmentof new antitumor agents since propolis administration tomammals (eg rats) does not lead to detectable side effects[3] Briefly this natural product can block specific oncogenesignalling pathways which in turn lead to a decrease in cellproliferation and growth and can also act by decreasing thecancer stem cell population increasing apoptosis exertingantiangiogenic effects and modulating the tumour microen-vironment [66 152 153] Table 8 summarizes the antitumouractivity of propolis from different geographic origin and itschemical constituents

Some researchers showed the effect of different types ofpropolis and its constituents on cancer cell growth prolifera-tion and apoptosisThe hexane extract of propolis fromThai-land collected by the stingless bee Trigona laeviceps whichhas a different behavior in propolis collection compared tothe honey bees exerts antiproliferative activity against fivetested cancer cell lines (Chago KATO-III SW620 BT474and Hep-G2) but not against the normal cell lines tested(HS27 fibroblast and CH-liver) [5] A sample of PEE fromPoland inhibited human malignant melanoma (Me45) andcolorectal cancer (HCT 116) cells growth as well as reducedcell size [154]Other studies reported the antitumor activity ofBrazilianPEE [155ndash158]which regulate the protein expressionof cyclin D1 B1 and cyclin dependent kinase (CDK) as wellas p21 in human prostate cancer cells significantly affectingproliferation [158]

Although propolis containing CAPE is different fromthose with artepillin C it is possible to obtain a similarinhibitory effect from both types The effect of CAPE on

different cancer cell lines was analysed and many of itseffects have been shown to be mediated through inhibitionof NF-120581B [66 159] CAPE can inhibit the proliferation of thecolorectal cell line SW480 by decreasing the 120573-catenin c-myc and cyclin D1 protein expression [160] Chuu et al [161]observed that CAPE suppressed the proliferation of LNCaPDU-145 and PC-3 human prostate cancer cells in a dose-dependent manner and also inhibited the tumour growthof LNCaP xenografts in nude mice It was suggested that itacted through inhibition of p70S6K (an intermediary of thePI3KAKTpathway responsible for the protein synthesis) andsome Akt signalling networks Wu et al [162] demonstratedthat CAPE inhibits in vitro and in vivoMCF-7 andMDA-MB-231 tumour growthwithoutmuch effect on normalmammarycells by reducing the expression of growth and transcriptionfactors including NF-120581B Recently it was demonstrated thatCAPE effect on genes that are associated with tumour cellgrowth and survival is related in part to its role as a histonedeacetylase inhibitor [163]

As previously said propolis can also act by decreasingthe cancer stem cell population Using the putative CD44(+)CD24 (minuslow) breast cancer stem cells able to generatemammospheres from single cells Omene et al [164] showedthat CAPE caused a dose-dependent inhibition of cancerstem cells self-renewal progenitor formation and clonalgrowth

Concerning cell death some in vitro studies showeddifferent sensitivities of tumour cells to propolis extractsPWE from Iraq inhibits the proliferation of HL-60 cellsand leads to downregulation of Bcl-2 and activation of Bax[13] Alizadeh et al [165] investigated the protective effectsof Iranian PEE on N-methyl-N-nitro-N-nitrosoguanidine-(MNNG-) initiated gastric cancer in rats Results showedthat tumour incidence the number of lesions structuralabnormalities and beta-catenin of the animals group treatedwith PEE significantly declined compared with the controlPEE also induced the expression of proapoptotic Bax andreduced antiapoptotic Bcl-2 expression Propolis inhibitscolony formation potential and promotes necrotic changes inHCT-116 cells and decreases mitotic cells and increases p53and Ki-67 expression in HCT-116 tumor-bearing mice [13]Szliszkarsquos group have performed many studies to analyze theantitumour effect of different propolis and its constituentson prostate cancer cells (LNCaP and DU145) [166ndash168]Brazilian green PEE sensitized these cells to TRAIL-induceddeath enhanced the expression of TRAIL-R2 and decreasedthe activity of NF-120581B in LNCaP cells [167] Cotreatment ofTRAIL with artepillin C induced the significant activation ofcaspase-8 and caspase-3 as well as a significant disruption ofthe mitochondrial membrane potential [169] Many studieshave been conducted to understand the pathways involvedin the apoptotic effect of CAPE CAPE induces cell cyclearrest and apoptosis and reduces expression of NF-120581B inMDA-MB-231 and MCF-7 human breast cancer cells [162]In PC3 prostate cancer cells CAPE induced apoptosis in adose-dependent manner that was associated with the loss ofexpression of the inhibitors of apoptosis cIAP-1 cIAP-2 andXIAP [170] Cavaliere et al [171] showed that CAPE treatment

of lymphoblastoid cell line PL104 induced apoptosis throughthe mitochondrial intrinsic pathway

It has been known that cancer microenvironment isvery important for carcinogenesis and it consists of stromalendothelial immune and cancer cells Natural productslike propolis and their constituents have been shown tointerfere with this symbiosis It was demonstrated by Lee et al[172] that CAPE could effectively suppress the adhesion andinvasion potential of human hepatocellular carcinoma cells(SK-Hep1) by inhibiting the expression ofMMP-2 andMMP-9 and NF-120581B

Angiogenesis has a crucial role in tumour growth dueto the requirement of oxygen and nutrients to sustain rapiduncontrolled proliferation and metastization Both tumourand stromal cells can secrete proangiogenic factors thatstimulate the formation andmaintenance of new vessels suchas vascular endothelial growth factor (VEGF) [173] BrazilianPEE could significantly reduce the number of newly formedvessels and suppress the proliferation of human umbilicalvein endothelial cells (HUVECs) [174] this antiangiogeniceffect being mainly mediated via inducing apoptosis in tube-forming endothelial cells through the inactivation of the sur-vival signal ERK12 [175] Yun et al [176] observed that CAPEinhibited angiogenesis using the in vivo assay chick embryochorioallantoic membrane (CAM) CAPE also suppressesVEGF formation by MDA-MB-231 cells and formation ofcapillary-like tubes by endothelial cells [162 177] Extractsof propolis containing artepillin C and CAPE significantlyreduced the newly formed vessels and expression of MMPsand VEGF production from various cells [178] and inaccordance with this study Izuta et al [179] described thatCAPE promotes inhibition of VEGF expression in HUVECcells

The first study on the antitumor activity of Portuguesepropolis was only performed in 2010 Using normal andcancerous renal cells derived from human renal cell carci-noma (RCC) patients in addition to A-498 cell line Valenteet al [64] showed that methanolic extract of Portuguesepropolis exhibited selective toxicity against malignant cellscompared to normal cells and in vitro RCC growth wasstrongly inhibited Recently our group demonstrated theantitumour and antiangiogenic activity of the ethanol extractof Pereiro propolis (P10EE) collected in the district ofGuarda Portugal P10EE affects cell viability of differenttumour cells MDA-MB-231 (breast) and DU145 (prostate)being two of the most sensitive ones but was less cytotoxicagainst nontumour cells and fibroblasts Also it signifi-cantly decreased MDA-MB-231 and DU145 cell prolifera-tion and migration along time with cell cycle changesand increased cell death The significant increase observedin glucose consumption and lactate production could beexplained in MDA-MB-231 by an increased expression ofhypoxia inducible factor-1120572 pyruvate dehydrogenase kinaseglucose transporter 1 lactate dehydrogenase and carbonicanhydrase Furthermore P10EE induced a decrease inHBMECs total biomass and proliferation and decreasedvessel sprouting in the chicken chorioallantoic membrane[23]

5 Conclusions

From ancient to modern times herbs and other plant prod-ucts have been widely used as medicinal agents first in folkmedicine and other activities in many parts of the world andlater developed and improved on a scientific basis into drugsthat are used in the health system Propolis is one of thefew natural products that has maintained its popularity overa long period of time As reviewed here propolis containsa broad spectrum of compounds that may be useful in thetreatment of different pathological conditions In fact there ismuch literature that deals with the in vitro and in vivo biologi-cal properties of propolisThis wide range of bioactivities thecontinuous discovery of new compounds the long history ofpropolis use and its safety profile make propolis a potentialcandidate for drug discovery that may be useful in severalclinical scenarios Nevertheless it is necessary to make aneffort to standardize propolis composition since it seems thatpropolis biological properties and chemical composition notonly are variable but also are strictly linked In our opinionpropolis extracts may be important economically and wouldallow a relatively inexpensive treatment in different diseaseshowever to promote its use in modern medicine it will benecessary to identify and isolate the bioactive compoundsto be tested separately or in combination with other drugsalready available

Drug discovery does not consist only of the isolationof bioactive lead compounds from the natural sources Infact this process continues outside the academic laboratoriesthrough preclinical studies followed by clinical trials Thusdespite the in vitro and in vivo assays which provide newvaluable information on propolis biological properties andmechanisms of action it will be necessary to analyse theeffectiveness of propolis clinically to complement the basicresearch available and to evaluate the potential of propolis inhuman health promotion

mechanism of CAPE H pylori a major factor for gas-trointestinal illnesses contains the enzyme H pylori peptidedeformylase that catalyses the removal of formyl group fromthe N-terminus of nascent polypeptide chains Since theaction of this enzyme is essential for H pylori survival it isconsidered a promising therapeutic drug target Results fromabsorption spectra and crystal structural characterizationshowed that CAPE is a competitive inhibitor of peptidedeformylase blocking the substrate entrance and preventingsubstrate from approaching the active site [131]

It has been suggested that the combination of propoliswith other antibiotics would allow dose reduction of selectedantibiotics thus potentiating their effect The antibacterialactivity of Italian PEE in some clinically isolated Gram-positive strains as well as the synergetic effect with someantibiotics was assessed by Scazzocchio et al [56] Ital-ian PEE drastically increased the effect of ampicillin gen-tamycin and streptomycin and moderated the action ofchloramphenicol ceftriaxone and vancomycin No effectwas observed when used simultaneously with erythromycinWojtyczka et al [132] evaluated the in vitro antimicrobialactivity of a Polish PEE against methicillin-sensitive S aureus(MSSA) and methicillin-resistant S aureus (MRSA) clinicalisolates and also the combined effect of propolis with tenselected antistaphylococcal drugs PEE displayed varyingeffectiveness against twelve S aureus strains and potentiatedthe antimicrobial effect of eight antistaphylococcal againstall tested strains No synergism was observed in the caseof ciprofloxacin and chloramphenicol In another study theeffect of dichloromethane extract of French propolis againstdifferent human pathogenic bacterial strains was also testedAlthough Gram-negative bacteria were not susceptible tothe extract a significant antibacterial activity against bothmethicillin-resistant and methicillin-susceptible S aureusstrains was observed [133] The same was confirmed byVelikova et al [28] using different PEE from BulgariaGreece Turkey and Algeria All the samples showed agood antibacterial activity against S aureus but a week orlacking effect against E coli Australian PEE from stinglessbee Tetragonula carbonaria also inhibited the growth of Saureus Nevertheless it was less active against P aeruginosa[42] The same was observed by Papachroni et al [53]using PEE from Cameroon and CongoContrary to thesestudies Katircioglu and Mercan [134] showed that TurkishPEE was effective against Gram-negative bacteria like E coliOrsi et al [135] investigated the possible synergism betweenBrazilian and Bulgarian propolis and antibiotics acting onDNA (ciprofloxacin and norfloxacin) and on metabolism(cotrimoxazole) in Salmonella typhi Both samples hadantibacterial activity but no synergistic effect was detected

Recently the suitability of nanohydroxyapatite- (nano-HA-) based surfaces containing two Brazilian PEE (greenand red ones) to prevent S aureus bacterial growth andbiofilm was studied The nanoHA impregnated with thetwo highest concentrations (12 and 25120583gmL) of red PEEshowed a remarkable reduction of 99 in the number ofviable bacteria while nanoHA with green PEE at sameconcentrations showed a reduction of 45 and 61 Moreoverthe nanoHA impregnated with the highest concentration of

red PEE was able to inhibit 80 of the staphylococcal biofilmformation [136]

Diverse studies show that as the composition of propolisvaries from region to region the antibacterial activity alsodisplays some variations [59] Susceptibility of differentGram-positive bacteria to PEE varies with the place ofpropolis collection [137] The antibacterial effect was shownto be higher for samples from a wet-tropical rain forest-type climate Other studies revealed the influence of propolisgeographical origin on its antibacterial properties [57 58 138139] Propolis from the north and centre of Portugal has agreat activity against S aureus [58 140]

452 Antifungal Activity Antifungal activity is also influ-enced by the chemical variation of propolis [59] Severalstudies have shown the effect of propolis from differentgeographic origin against different fungi particularly ofclinical interest [141ndash145] Quiroga et al [146] demonstratedthe antifungal activity of propolis from the northwest ofArgentina focusing their study on the environment andthe development of agrochemicals with reduced economiccosts possibly containing propolis extracts and its isolatedcompounds such as pinocembrin and galangin as activeprinciples

Recently Falcao et al [140] screened the antifungalactivity of Portuguese propolis and its potential floral sourcesPopulus x Canadensis and Cistus ladanifer against Candidaalbicans Trichophyton rubrum and Aspergillus fumigatusPlant extracts did not exhibit relevant antifungal activity withexception of T rubrum but both propolis samples revealedsimilar antifungal activity the highest being obtained againstT rubrum and the lowest against A fumigatus A sample ofPEE from Poland showed a high fungicidal activity againstC albicans C glabrata and C krusei [147] Recently it wasshown that different organic extracts of French propolis (PEEPWEmethanolic extract and dichloromethane extract) wereeffective against C albicans and C glabrata but only have aweak activity towards A fumigates [133]

Brazilian PEE was proved to be active against severalCandida strains (C albicans C tropicalis C krusei andC guilliermondii) C albicans being the most sensitive andC guilliermondii the most resistant [141] Brazilian greenand red propolis display activity against different fungalspecies of Trichophyton which cause dermatophytosis redPEE being more efficient than the green one [143] Also itwas shown that n-hexane extract of Brazilian red propolisdid not induce resistance in Candida spp In fact it wasactive against Candida spp resistant to antifungal agentslike fluconazole [148] Dota et al [144] evaluated the in vitroantifungal activity of PEE and propolis microparticles (PMs)obtained from a sample from Argentina against clinical yeastisolates of importance in the vulvovaginal candidiasis Calbicans and non-C albicanswere inhibited by PEE and PMswith small variation Additionally it was shown that Braziliangreen PEE has the ability to inhibit growth and biofilmformation by C albicans from vulvovaginal candidiasis [149]Another study showed fungicide action of propolis (PEEPWE propolis matricial microparticles (PMM) and propolissoluble dry extract after 6ndash8-hour treatment against all three

C albicansmorphotypes (yeast pseudohyphae and hyphae)PEE being the most potent followed by PSDE PM andPWE [150] Brazilian propolis induces C albicans cell deathmediated via metacaspase since the metacaspase mutant inC albicans showed reduced sensitivity to propolis and bythe Ras pathway Using C albicans deletion libraries it waspossible to screen several mutants in genes involved eitherin the morphological transitions or in the maintenance of aspecific morphotype that are more sensitive to propolis Toconclude the study the authors also showed that propolisbased gels and cream were partially able to control vulvo-vaginal candidiasis in a mouse model [151] These studies[144] strongly indicate that propolis has a great potential tocontrol vulvovaginal candidiasis representing a promisingalternative therapeutic strategy

46 Antitumour Activity Recognition of the hallmarks ofcancer affects the search and development of new meth-ods and therapeutic agents with a sufficiently large thera-peutic window to kill tumour cells while sparing normalcells In the last years the natural product propolis hasattracted a growing interest by a large number of researcherssince it contains a variety of phytochemical compoundsthat may act through multiple pathways to reduce thedevelopment and other malignant characteristics of cancercells

Recently several in vitro studies have demonstrated acytotoxic action of propolis from different geographic originand of some of its isolated compounds on various tumourcells In vivo studies also show a potential in the developmentof new antitumor agents since propolis administration tomammals (eg rats) does not lead to detectable side effects[3] Briefly this natural product can block specific oncogenesignalling pathways which in turn lead to a decrease in cellproliferation and growth and can also act by decreasing thecancer stem cell population increasing apoptosis exertingantiangiogenic effects and modulating the tumour microen-vironment [66 152 153] Table 8 summarizes the antitumouractivity of propolis from different geographic origin and itschemical constituents

Some researchers showed the effect of different types ofpropolis and its constituents on cancer cell growth prolifera-tion and apoptosisThe hexane extract of propolis fromThai-land collected by the stingless bee Trigona laeviceps whichhas a different behavior in propolis collection compared tothe honey bees exerts antiproliferative activity against fivetested cancer cell lines (Chago KATO-III SW620 BT474and Hep-G2) but not against the normal cell lines tested(HS27 fibroblast and CH-liver) [5] A sample of PEE fromPoland inhibited human malignant melanoma (Me45) andcolorectal cancer (HCT 116) cells growth as well as reducedcell size [154]Other studies reported the antitumor activity ofBrazilianPEE [155ndash158]which regulate the protein expressionof cyclin D1 B1 and cyclin dependent kinase (CDK) as wellas p21 in human prostate cancer cells significantly affectingproliferation [158]

Although propolis containing CAPE is different fromthose with artepillin C it is possible to obtain a similarinhibitory effect from both types The effect of CAPE on

different cancer cell lines was analysed and many of itseffects have been shown to be mediated through inhibitionof NF-120581B [66 159] CAPE can inhibit the proliferation of thecolorectal cell line SW480 by decreasing the 120573-catenin c-myc and cyclin D1 protein expression [160] Chuu et al [161]observed that CAPE suppressed the proliferation of LNCaPDU-145 and PC-3 human prostate cancer cells in a dose-dependent manner and also inhibited the tumour growthof LNCaP xenografts in nude mice It was suggested that itacted through inhibition of p70S6K (an intermediary of thePI3KAKTpathway responsible for the protein synthesis) andsome Akt signalling networks Wu et al [162] demonstratedthat CAPE inhibits in vitro and in vivoMCF-7 andMDA-MB-231 tumour growthwithoutmuch effect on normalmammarycells by reducing the expression of growth and transcriptionfactors including NF-120581B Recently it was demonstrated thatCAPE effect on genes that are associated with tumour cellgrowth and survival is related in part to its role as a histonedeacetylase inhibitor [163]

As previously said propolis can also act by decreasingthe cancer stem cell population Using the putative CD44(+)CD24 (minuslow) breast cancer stem cells able to generatemammospheres from single cells Omene et al [164] showedthat CAPE caused a dose-dependent inhibition of cancerstem cells self-renewal progenitor formation and clonalgrowth

Concerning cell death some in vitro studies showeddifferent sensitivities of tumour cells to propolis extractsPWE from Iraq inhibits the proliferation of HL-60 cellsand leads to downregulation of Bcl-2 and activation of Bax[13] Alizadeh et al [165] investigated the protective effectsof Iranian PEE on N-methyl-N-nitro-N-nitrosoguanidine-(MNNG-) initiated gastric cancer in rats Results showedthat tumour incidence the number of lesions structuralabnormalities and beta-catenin of the animals group treatedwith PEE significantly declined compared with the controlPEE also induced the expression of proapoptotic Bax andreduced antiapoptotic Bcl-2 expression Propolis inhibitscolony formation potential and promotes necrotic changes inHCT-116 cells and decreases mitotic cells and increases p53and Ki-67 expression in HCT-116 tumor-bearing mice [13]Szliszkarsquos group have performed many studies to analyze theantitumour effect of different propolis and its constituentson prostate cancer cells (LNCaP and DU145) [166ndash168]Brazilian green PEE sensitized these cells to TRAIL-induceddeath enhanced the expression of TRAIL-R2 and decreasedthe activity of NF-120581B in LNCaP cells [167] Cotreatment ofTRAIL with artepillin C induced the significant activation ofcaspase-8 and caspase-3 as well as a significant disruption ofthe mitochondrial membrane potential [169] Many studieshave been conducted to understand the pathways involvedin the apoptotic effect of CAPE CAPE induces cell cyclearrest and apoptosis and reduces expression of NF-120581B inMDA-MB-231 and MCF-7 human breast cancer cells [162]In PC3 prostate cancer cells CAPE induced apoptosis in adose-dependent manner that was associated with the loss ofexpression of the inhibitors of apoptosis cIAP-1 cIAP-2 andXIAP [170] Cavaliere et al [171] showed that CAPE treatment

of lymphoblastoid cell line PL104 induced apoptosis throughthe mitochondrial intrinsic pathway

It has been known that cancer microenvironment isvery important for carcinogenesis and it consists of stromalendothelial immune and cancer cells Natural productslike propolis and their constituents have been shown tointerfere with this symbiosis It was demonstrated by Lee et al[172] that CAPE could effectively suppress the adhesion andinvasion potential of human hepatocellular carcinoma cells(SK-Hep1) by inhibiting the expression ofMMP-2 andMMP-9 and NF-120581B

Angiogenesis has a crucial role in tumour growth dueto the requirement of oxygen and nutrients to sustain rapiduncontrolled proliferation and metastization Both tumourand stromal cells can secrete proangiogenic factors thatstimulate the formation andmaintenance of new vessels suchas vascular endothelial growth factor (VEGF) [173] BrazilianPEE could significantly reduce the number of newly formedvessels and suppress the proliferation of human umbilicalvein endothelial cells (HUVECs) [174] this antiangiogeniceffect being mainly mediated via inducing apoptosis in tube-forming endothelial cells through the inactivation of the sur-vival signal ERK12 [175] Yun et al [176] observed that CAPEinhibited angiogenesis using the in vivo assay chick embryochorioallantoic membrane (CAM) CAPE also suppressesVEGF formation by MDA-MB-231 cells and formation ofcapillary-like tubes by endothelial cells [162 177] Extractsof propolis containing artepillin C and CAPE significantlyreduced the newly formed vessels and expression of MMPsand VEGF production from various cells [178] and inaccordance with this study Izuta et al [179] described thatCAPE promotes inhibition of VEGF expression in HUVECcells

The first study on the antitumor activity of Portuguesepropolis was only performed in 2010 Using normal andcancerous renal cells derived from human renal cell carci-noma (RCC) patients in addition to A-498 cell line Valenteet al [64] showed that methanolic extract of Portuguesepropolis exhibited selective toxicity against malignant cellscompared to normal cells and in vitro RCC growth wasstrongly inhibited Recently our group demonstrated theantitumour and antiangiogenic activity of the ethanol extractof Pereiro propolis (P10EE) collected in the district ofGuarda Portugal P10EE affects cell viability of differenttumour cells MDA-MB-231 (breast) and DU145 (prostate)being two of the most sensitive ones but was less cytotoxicagainst nontumour cells and fibroblasts Also it signifi-cantly decreased MDA-MB-231 and DU145 cell prolifera-tion and migration along time with cell cycle changesand increased cell death The significant increase observedin glucose consumption and lactate production could beexplained in MDA-MB-231 by an increased expression ofhypoxia inducible factor-1120572 pyruvate dehydrogenase kinaseglucose transporter 1 lactate dehydrogenase and carbonicanhydrase Furthermore P10EE induced a decrease inHBMECs total biomass and proliferation and decreasedvessel sprouting in the chicken chorioallantoic membrane[23]

5 Conclusions

From ancient to modern times herbs and other plant prod-ucts have been widely used as medicinal agents first in folkmedicine and other activities in many parts of the world andlater developed and improved on a scientific basis into drugsthat are used in the health system Propolis is one of thefew natural products that has maintained its popularity overa long period of time As reviewed here propolis containsa broad spectrum of compounds that may be useful in thetreatment of different pathological conditions In fact there ismuch literature that deals with the in vitro and in vivo biologi-cal properties of propolisThis wide range of bioactivities thecontinuous discovery of new compounds the long history ofpropolis use and its safety profile make propolis a potentialcandidate for drug discovery that may be useful in severalclinical scenarios Nevertheless it is necessary to make aneffort to standardize propolis composition since it seems thatpropolis biological properties and chemical composition notonly are variable but also are strictly linked In our opinionpropolis extracts may be important economically and wouldallow a relatively inexpensive treatment in different diseaseshowever to promote its use in modern medicine it will benecessary to identify and isolate the bioactive compoundsto be tested separately or in combination with other drugsalready available

Drug discovery does not consist only of the isolationof bioactive lead compounds from the natural sources Infact this process continues outside the academic laboratoriesthrough preclinical studies followed by clinical trials Thusdespite the in vitro and in vivo assays which provide newvaluable information on propolis biological properties andmechanisms of action it will be necessary to analyse theeffectiveness of propolis clinically to complement the basicresearch available and to evaluate the potential of propolis inhuman health promotion

C albicansmorphotypes (yeast pseudohyphae and hyphae)PEE being the most potent followed by PSDE PM andPWE [150] Brazilian propolis induces C albicans cell deathmediated via metacaspase since the metacaspase mutant inC albicans showed reduced sensitivity to propolis and bythe Ras pathway Using C albicans deletion libraries it waspossible to screen several mutants in genes involved eitherin the morphological transitions or in the maintenance of aspecific morphotype that are more sensitive to propolis Toconclude the study the authors also showed that propolisbased gels and cream were partially able to control vulvo-vaginal candidiasis in a mouse model [151] These studies[144] strongly indicate that propolis has a great potential tocontrol vulvovaginal candidiasis representing a promisingalternative therapeutic strategy

46 Antitumour Activity Recognition of the hallmarks ofcancer affects the search and development of new meth-ods and therapeutic agents with a sufficiently large thera-peutic window to kill tumour cells while sparing normalcells In the last years the natural product propolis hasattracted a growing interest by a large number of researcherssince it contains a variety of phytochemical compoundsthat may act through multiple pathways to reduce thedevelopment and other malignant characteristics of cancercells

Recently several in vitro studies have demonstrated acytotoxic action of propolis from different geographic originand of some of its isolated compounds on various tumourcells In vivo studies also show a potential in the developmentof new antitumor agents since propolis administration tomammals (eg rats) does not lead to detectable side effects[3] Briefly this natural product can block specific oncogenesignalling pathways which in turn lead to a decrease in cellproliferation and growth and can also act by decreasing thecancer stem cell population increasing apoptosis exertingantiangiogenic effects and modulating the tumour microen-vironment [66 152 153] Table 8 summarizes the antitumouractivity of propolis from different geographic origin and itschemical constituents

Some researchers showed the effect of different types ofpropolis and its constituents on cancer cell growth prolifera-tion and apoptosisThe hexane extract of propolis fromThai-land collected by the stingless bee Trigona laeviceps whichhas a different behavior in propolis collection compared tothe honey bees exerts antiproliferative activity against fivetested cancer cell lines (Chago KATO-III SW620 BT474and Hep-G2) but not against the normal cell lines tested(HS27 fibroblast and CH-liver) [5] A sample of PEE fromPoland inhibited human malignant melanoma (Me45) andcolorectal cancer (HCT 116) cells growth as well as reducedcell size [154]Other studies reported the antitumor activity ofBrazilianPEE [155ndash158]which regulate the protein expressionof cyclin D1 B1 and cyclin dependent kinase (CDK) as wellas p21 in human prostate cancer cells significantly affectingproliferation [158]

Although propolis containing CAPE is different fromthose with artepillin C it is possible to obtain a similarinhibitory effect from both types The effect of CAPE on

different cancer cell lines was analysed and many of itseffects have been shown to be mediated through inhibitionof NF-120581B [66 159] CAPE can inhibit the proliferation of thecolorectal cell line SW480 by decreasing the 120573-catenin c-myc and cyclin D1 protein expression [160] Chuu et al [161]observed that CAPE suppressed the proliferation of LNCaPDU-145 and PC-3 human prostate cancer cells in a dose-dependent manner and also inhibited the tumour growthof LNCaP xenografts in nude mice It was suggested that itacted through inhibition of p70S6K (an intermediary of thePI3KAKTpathway responsible for the protein synthesis) andsome Akt signalling networks Wu et al [162] demonstratedthat CAPE inhibits in vitro and in vivoMCF-7 andMDA-MB-231 tumour growthwithoutmuch effect on normalmammarycells by reducing the expression of growth and transcriptionfactors including NF-120581B Recently it was demonstrated thatCAPE effect on genes that are associated with tumour cellgrowth and survival is related in part to its role as a histonedeacetylase inhibitor [163]

As previously said propolis can also act by decreasingthe cancer stem cell population Using the putative CD44(+)CD24 (minuslow) breast cancer stem cells able to generatemammospheres from single cells Omene et al [164] showedthat CAPE caused a dose-dependent inhibition of cancerstem cells self-renewal progenitor formation and clonalgrowth

Concerning cell death some in vitro studies showeddifferent sensitivities of tumour cells to propolis extractsPWE from Iraq inhibits the proliferation of HL-60 cellsand leads to downregulation of Bcl-2 and activation of Bax[13] Alizadeh et al [165] investigated the protective effectsof Iranian PEE on N-methyl-N-nitro-N-nitrosoguanidine-(MNNG-) initiated gastric cancer in rats Results showedthat tumour incidence the number of lesions structuralabnormalities and beta-catenin of the animals group treatedwith PEE significantly declined compared with the controlPEE also induced the expression of proapoptotic Bax andreduced antiapoptotic Bcl-2 expression Propolis inhibitscolony formation potential and promotes necrotic changes inHCT-116 cells and decreases mitotic cells and increases p53and Ki-67 expression in HCT-116 tumor-bearing mice [13]Szliszkarsquos group have performed many studies to analyze theantitumour effect of different propolis and its constituentson prostate cancer cells (LNCaP and DU145) [166ndash168]Brazilian green PEE sensitized these cells to TRAIL-induceddeath enhanced the expression of TRAIL-R2 and decreasedthe activity of NF-120581B in LNCaP cells [167] Cotreatment ofTRAIL with artepillin C induced the significant activation ofcaspase-8 and caspase-3 as well as a significant disruption ofthe mitochondrial membrane potential [169] Many studieshave been conducted to understand the pathways involvedin the apoptotic effect of CAPE CAPE induces cell cyclearrest and apoptosis and reduces expression of NF-120581B inMDA-MB-231 and MCF-7 human breast cancer cells [162]In PC3 prostate cancer cells CAPE induced apoptosis in adose-dependent manner that was associated with the loss ofexpression of the inhibitors of apoptosis cIAP-1 cIAP-2 andXIAP [170] Cavaliere et al [171] showed that CAPE treatment

of lymphoblastoid cell line PL104 induced apoptosis throughthe mitochondrial intrinsic pathway

It has been known that cancer microenvironment isvery important for carcinogenesis and it consists of stromalendothelial immune and cancer cells Natural productslike propolis and their constituents have been shown tointerfere with this symbiosis It was demonstrated by Lee et al[172] that CAPE could effectively suppress the adhesion andinvasion potential of human hepatocellular carcinoma cells(SK-Hep1) by inhibiting the expression ofMMP-2 andMMP-9 and NF-120581B

Angiogenesis has a crucial role in tumour growth dueto the requirement of oxygen and nutrients to sustain rapiduncontrolled proliferation and metastization Both tumourand stromal cells can secrete proangiogenic factors thatstimulate the formation andmaintenance of new vessels suchas vascular endothelial growth factor (VEGF) [173] BrazilianPEE could significantly reduce the number of newly formedvessels and suppress the proliferation of human umbilicalvein endothelial cells (HUVECs) [174] this antiangiogeniceffect being mainly mediated via inducing apoptosis in tube-forming endothelial cells through the inactivation of the sur-vival signal ERK12 [175] Yun et al [176] observed that CAPEinhibited angiogenesis using the in vivo assay chick embryochorioallantoic membrane (CAM) CAPE also suppressesVEGF formation by MDA-MB-231 cells and formation ofcapillary-like tubes by endothelial cells [162 177] Extractsof propolis containing artepillin C and CAPE significantlyreduced the newly formed vessels and expression of MMPsand VEGF production from various cells [178] and inaccordance with this study Izuta et al [179] described thatCAPE promotes inhibition of VEGF expression in HUVECcells

The first study on the antitumor activity of Portuguesepropolis was only performed in 2010 Using normal andcancerous renal cells derived from human renal cell carci-noma (RCC) patients in addition to A-498 cell line Valenteet al [64] showed that methanolic extract of Portuguesepropolis exhibited selective toxicity against malignant cellscompared to normal cells and in vitro RCC growth wasstrongly inhibited Recently our group demonstrated theantitumour and antiangiogenic activity of the ethanol extractof Pereiro propolis (P10EE) collected in the district ofGuarda Portugal P10EE affects cell viability of differenttumour cells MDA-MB-231 (breast) and DU145 (prostate)being two of the most sensitive ones but was less cytotoxicagainst nontumour cells and fibroblasts Also it signifi-cantly decreased MDA-MB-231 and DU145 cell prolifera-tion and migration along time with cell cycle changesand increased cell death The significant increase observedin glucose consumption and lactate production could beexplained in MDA-MB-231 by an increased expression ofhypoxia inducible factor-1120572 pyruvate dehydrogenase kinaseglucose transporter 1 lactate dehydrogenase and carbonicanhydrase Furthermore P10EE induced a decrease inHBMECs total biomass and proliferation and decreasedvessel sprouting in the chicken chorioallantoic membrane[23]

5 Conclusions

From ancient to modern times herbs and other plant prod-ucts have been widely used as medicinal agents first in folkmedicine and other activities in many parts of the world andlater developed and improved on a scientific basis into drugsthat are used in the health system Propolis is one of thefew natural products that has maintained its popularity overa long period of time As reviewed here propolis containsa broad spectrum of compounds that may be useful in thetreatment of different pathological conditions In fact there ismuch literature that deals with the in vitro and in vivo biologi-cal properties of propolisThis wide range of bioactivities thecontinuous discovery of new compounds the long history ofpropolis use and its safety profile make propolis a potentialcandidate for drug discovery that may be useful in severalclinical scenarios Nevertheless it is necessary to make aneffort to standardize propolis composition since it seems thatpropolis biological properties and chemical composition notonly are variable but also are strictly linked In our opinionpropolis extracts may be important economically and wouldallow a relatively inexpensive treatment in different diseaseshowever to promote its use in modern medicine it will benecessary to identify and isolate the bioactive compoundsto be tested separately or in combination with other drugsalready available

Drug discovery does not consist only of the isolationof bioactive lead compounds from the natural sources Infact this process continues outside the academic laboratoriesthrough preclinical studies followed by clinical trials Thusdespite the in vitro and in vivo assays which provide newvaluable information on propolis biological properties andmechanisms of action it will be necessary to analyse theeffectiveness of propolis clinically to complement the basicresearch available and to evaluate the potential of propolis inhuman health promotion

It has been known that cancer microenvironment isvery important for carcinogenesis and it consists of stromalendothelial immune and cancer cells Natural productslike propolis and their constituents have been shown tointerfere with this symbiosis It was demonstrated by Lee et al[172] that CAPE could effectively suppress the adhesion andinvasion potential of human hepatocellular carcinoma cells(SK-Hep1) by inhibiting the expression ofMMP-2 andMMP-9 and NF-120581B

Angiogenesis has a crucial role in tumour growth dueto the requirement of oxygen and nutrients to sustain rapiduncontrolled proliferation and metastization Both tumourand stromal cells can secrete proangiogenic factors thatstimulate the formation andmaintenance of new vessels suchas vascular endothelial growth factor (VEGF) [173] BrazilianPEE could significantly reduce the number of newly formedvessels and suppress the proliferation of human umbilicalvein endothelial cells (HUVECs) [174] this antiangiogeniceffect being mainly mediated via inducing apoptosis in tube-forming endothelial cells through the inactivation of the sur-vival signal ERK12 [175] Yun et al [176] observed that CAPEinhibited angiogenesis using the in vivo assay chick embryochorioallantoic membrane (CAM) CAPE also suppressesVEGF formation by MDA-MB-231 cells and formation ofcapillary-like tubes by endothelial cells [162 177] Extractsof propolis containing artepillin C and CAPE significantlyreduced the newly formed vessels and expression of MMPsand VEGF production from various cells [178] and inaccordance with this study Izuta et al [179] described thatCAPE promotes inhibition of VEGF expression in HUVECcells

The first study on the antitumor activity of Portuguesepropolis was only performed in 2010 Using normal andcancerous renal cells derived from human renal cell carci-noma (RCC) patients in addition to A-498 cell line Valenteet al [64] showed that methanolic extract of Portuguesepropolis exhibited selective toxicity against malignant cellscompared to normal cells and in vitro RCC growth wasstrongly inhibited Recently our group demonstrated theantitumour and antiangiogenic activity of the ethanol extractof Pereiro propolis (P10EE) collected in the district ofGuarda Portugal P10EE affects cell viability of differenttumour cells MDA-MB-231 (breast) and DU145 (prostate)being two of the most sensitive ones but was less cytotoxicagainst nontumour cells and fibroblasts Also it signifi-cantly decreased MDA-MB-231 and DU145 cell prolifera-tion and migration along time with cell cycle changesand increased cell death The significant increase observedin glucose consumption and lactate production could beexplained in MDA-MB-231 by an increased expression ofhypoxia inducible factor-1120572 pyruvate dehydrogenase kinaseglucose transporter 1 lactate dehydrogenase and carbonicanhydrase Furthermore P10EE induced a decrease inHBMECs total biomass and proliferation and decreasedvessel sprouting in the chicken chorioallantoic membrane[23]

5 Conclusions

From ancient to modern times herbs and other plant prod-ucts have been widely used as medicinal agents first in folkmedicine and other activities in many parts of the world andlater developed and improved on a scientific basis into drugsthat are used in the health system Propolis is one of thefew natural products that has maintained its popularity overa long period of time As reviewed here propolis containsa broad spectrum of compounds that may be useful in thetreatment of different pathological conditions In fact there ismuch literature that deals with the in vitro and in vivo biologi-cal properties of propolisThis wide range of bioactivities thecontinuous discovery of new compounds the long history ofpropolis use and its safety profile make propolis a potentialcandidate for drug discovery that may be useful in severalclinical scenarios Nevertheless it is necessary to make aneffort to standardize propolis composition since it seems thatpropolis biological properties and chemical composition notonly are variable but also are strictly linked In our opinionpropolis extracts may be important economically and wouldallow a relatively inexpensive treatment in different diseaseshowever to promote its use in modern medicine it will benecessary to identify and isolate the bioactive compoundsto be tested separately or in combination with other drugsalready available

Drug discovery does not consist only of the isolationof bioactive lead compounds from the natural sources Infact this process continues outside the academic laboratoriesthrough preclinical studies followed by clinical trials Thusdespite the in vitro and in vivo assays which provide newvaluable information on propolis biological properties andmechanisms of action it will be necessary to analyse theeffectiveness of propolis clinically to complement the basicresearch available and to evaluate the potential of propolis inhuman health promotion

of lymphoblastoid cell line PL104 induced apoptosis throughthe mitochondrial intrinsic pathway

It has been known that cancer microenvironment isvery important for carcinogenesis and it consists of stromalendothelial immune and cancer cells Natural productslike propolis and their constituents have been shown tointerfere with this symbiosis It was demonstrated by Lee et al[172] that CAPE could effectively suppress the adhesion andinvasion potential of human hepatocellular carcinoma cells(SK-Hep1) by inhibiting the expression ofMMP-2 andMMP-9 and NF-120581B

Angiogenesis has a crucial role in tumour growth dueto the requirement of oxygen and nutrients to sustain rapiduncontrolled proliferation and metastization Both tumourand stromal cells can secrete proangiogenic factors thatstimulate the formation andmaintenance of new vessels suchas vascular endothelial growth factor (VEGF) [173] BrazilianPEE could significantly reduce the number of newly formedvessels and suppress the proliferation of human umbilicalvein endothelial cells (HUVECs) [174] this antiangiogeniceffect being mainly mediated via inducing apoptosis in tube-forming endothelial cells through the inactivation of the sur-vival signal ERK12 [175] Yun et al [176] observed that CAPEinhibited angiogenesis using the in vivo assay chick embryochorioallantoic membrane (CAM) CAPE also suppressesVEGF formation by MDA-MB-231 cells and formation ofcapillary-like tubes by endothelial cells [162 177] Extractsof propolis containing artepillin C and CAPE significantlyreduced the newly formed vessels and expression of MMPsand VEGF production from various cells [178] and inaccordance with this study Izuta et al [179] described thatCAPE promotes inhibition of VEGF expression in HUVECcells

The first study on the antitumor activity of Portuguesepropolis was only performed in 2010 Using normal andcancerous renal cells derived from human renal cell carci-noma (RCC) patients in addition to A-498 cell line Valenteet al [64] showed that methanolic extract of Portuguesepropolis exhibited selective toxicity against malignant cellscompared to normal cells and in vitro RCC growth wasstrongly inhibited Recently our group demonstrated theantitumour and antiangiogenic activity of the ethanol extractof Pereiro propolis (P10EE) collected in the district ofGuarda Portugal P10EE affects cell viability of differenttumour cells MDA-MB-231 (breast) and DU145 (prostate)being two of the most sensitive ones but was less cytotoxicagainst nontumour cells and fibroblasts Also it signifi-cantly decreased MDA-MB-231 and DU145 cell prolifera-tion and migration along time with cell cycle changesand increased cell death The significant increase observedin glucose consumption and lactate production could beexplained in MDA-MB-231 by an increased expression ofhypoxia inducible factor-1120572 pyruvate dehydrogenase kinaseglucose transporter 1 lactate dehydrogenase and carbonicanhydrase Furthermore P10EE induced a decrease inHBMECs total biomass and proliferation and decreasedvessel sprouting in the chicken chorioallantoic membrane[23]

5 Conclusions

From ancient to modern times herbs and other plant prod-ucts have been widely used as medicinal agents first in folkmedicine and other activities in many parts of the world andlater developed and improved on a scientific basis into drugsthat are used in the health system Propolis is one of thefew natural products that has maintained its popularity overa long period of time As reviewed here propolis containsa broad spectrum of compounds that may be useful in thetreatment of different pathological conditions In fact there ismuch literature that deals with the in vitro and in vivo biologi-cal properties of propolisThis wide range of bioactivities thecontinuous discovery of new compounds the long history ofpropolis use and its safety profile make propolis a potentialcandidate for drug discovery that may be useful in severalclinical scenarios Nevertheless it is necessary to make aneffort to standardize propolis composition since it seems thatpropolis biological properties and chemical composition notonly are variable but also are strictly linked In our opinionpropolis extracts may be important economically and wouldallow a relatively inexpensive treatment in different diseaseshowever to promote its use in modern medicine it will benecessary to identify and isolate the bioactive compoundsto be tested separately or in combination with other drugsalready available

Drug discovery does not consist only of the isolationof bioactive lead compounds from the natural sources Infact this process continues outside the academic laboratoriesthrough preclinical studies followed by clinical trials Thusdespite the in vitro and in vivo assays which provide newvaluable information on propolis biological properties andmechanisms of action it will be necessary to analyse theeffectiveness of propolis clinically to complement the basicresearch available and to evaluate the potential of propolis inhuman health promotion

of lymphoblastoid cell line PL104 induced apoptosis throughthe mitochondrial intrinsic pathway

It has been known that cancer microenvironment isvery important for carcinogenesis and it consists of stromalendothelial immune and cancer cells Natural productslike propolis and their constituents have been shown tointerfere with this symbiosis It was demonstrated by Lee et al[172] that CAPE could effectively suppress the adhesion andinvasion potential of human hepatocellular carcinoma cells(SK-Hep1) by inhibiting the expression ofMMP-2 andMMP-9 and NF-120581B

Angiogenesis has a crucial role in tumour growth dueto the requirement of oxygen and nutrients to sustain rapiduncontrolled proliferation and metastization Both tumourand stromal cells can secrete proangiogenic factors thatstimulate the formation andmaintenance of new vessels suchas vascular endothelial growth factor (VEGF) [173] BrazilianPEE could significantly reduce the number of newly formedvessels and suppress the proliferation of human umbilicalvein endothelial cells (HUVECs) [174] this antiangiogeniceffect being mainly mediated via inducing apoptosis in tube-forming endothelial cells through the inactivation of the sur-vival signal ERK12 [175] Yun et al [176] observed that CAPEinhibited angiogenesis using the in vivo assay chick embryochorioallantoic membrane (CAM) CAPE also suppressesVEGF formation by MDA-MB-231 cells and formation ofcapillary-like tubes by endothelial cells [162 177] Extractsof propolis containing artepillin C and CAPE significantlyreduced the newly formed vessels and expression of MMPsand VEGF production from various cells [178] and inaccordance with this study Izuta et al [179] described thatCAPE promotes inhibition of VEGF expression in HUVECcells

The first study on the antitumor activity of Portuguesepropolis was only performed in 2010 Using normal andcancerous renal cells derived from human renal cell carci-noma (RCC) patients in addition to A-498 cell line Valenteet al [64] showed that methanolic extract of Portuguesepropolis exhibited selective toxicity against malignant cellscompared to normal cells and in vitro RCC growth wasstrongly inhibited Recently our group demonstrated theantitumour and antiangiogenic activity of the ethanol extractof Pereiro propolis (P10EE) collected in the district ofGuarda Portugal P10EE affects cell viability of differenttumour cells MDA-MB-231 (breast) and DU145 (prostate)being two of the most sensitive ones but was less cytotoxicagainst nontumour cells and fibroblasts Also it signifi-cantly decreased MDA-MB-231 and DU145 cell prolifera-tion and migration along time with cell cycle changesand increased cell death The significant increase observedin glucose consumption and lactate production could beexplained in MDA-MB-231 by an increased expression ofhypoxia inducible factor-1120572 pyruvate dehydrogenase kinaseglucose transporter 1 lactate dehydrogenase and carbonicanhydrase Furthermore P10EE induced a decrease inHBMECs total biomass and proliferation and decreasedvessel sprouting in the chicken chorioallantoic membrane[23]

5 Conclusions

From ancient to modern times herbs and other plant prod-ucts have been widely used as medicinal agents first in folkmedicine and other activities in many parts of the world andlater developed and improved on a scientific basis into drugsthat are used in the health system Propolis is one of thefew natural products that has maintained its popularity overa long period of time As reviewed here propolis containsa broad spectrum of compounds that may be useful in thetreatment of different pathological conditions In fact there ismuch literature that deals with the in vitro and in vivo biologi-cal properties of propolisThis wide range of bioactivities thecontinuous discovery of new compounds the long history ofpropolis use and its safety profile make propolis a potentialcandidate for drug discovery that may be useful in severalclinical scenarios Nevertheless it is necessary to make aneffort to standardize propolis composition since it seems thatpropolis biological properties and chemical composition notonly are variable but also are strictly linked In our opinionpropolis extracts may be important economically and wouldallow a relatively inexpensive treatment in different diseaseshowever to promote its use in modern medicine it will benecessary to identify and isolate the bioactive compoundsto be tested separately or in combination with other drugsalready available

Drug discovery does not consist only of the isolationof bioactive lead compounds from the natural sources Infact this process continues outside the academic laboratoriesthrough preclinical studies followed by clinical trials Thusdespite the in vitro and in vivo assays which provide newvaluable information on propolis biological properties andmechanisms of action it will be necessary to analyse theeffectiveness of propolis clinically to complement the basicresearch available and to evaluate the potential of propolis inhuman health promotion

It has been known that cancer microenvironment isvery important for carcinogenesis and it consists of stromalendothelial immune and cancer cells Natural productslike propolis and their constituents have been shown tointerfere with this symbiosis It was demonstrated by Lee et al[172] that CAPE could effectively suppress the adhesion andinvasion potential of human hepatocellular carcinoma cells(SK-Hep1) by inhibiting the expression ofMMP-2 andMMP-9 and NF-120581B

Angiogenesis has a crucial role in tumour growth dueto the requirement of oxygen and nutrients to sustain rapiduncontrolled proliferation and metastization Both tumourand stromal cells can secrete proangiogenic factors thatstimulate the formation andmaintenance of new vessels suchas vascular endothelial growth factor (VEGF) [173] BrazilianPEE could significantly reduce the number of newly formedvessels and suppress the proliferation of human umbilicalvein endothelial cells (HUVECs) [174] this antiangiogeniceffect being mainly mediated via inducing apoptosis in tube-forming endothelial cells through the inactivation of the sur-vival signal ERK12 [175] Yun et al [176] observed that CAPEinhibited angiogenesis using the in vivo assay chick embryochorioallantoic membrane (CAM) CAPE also suppressesVEGF formation by MDA-MB-231 cells and formation ofcapillary-like tubes by endothelial cells [162 177] Extractsof propolis containing artepillin C and CAPE significantlyreduced the newly formed vessels and expression of MMPsand VEGF production from various cells [178] and inaccordance with this study Izuta et al [179] described thatCAPE promotes inhibition of VEGF expression in HUVECcells

The first study on the antitumor activity of Portuguesepropolis was only performed in 2010 Using normal andcancerous renal cells derived from human renal cell carci-noma (RCC) patients in addition to A-498 cell line Valenteet al [64] showed that methanolic extract of Portuguesepropolis exhibited selective toxicity against malignant cellscompared to normal cells and in vitro RCC growth wasstrongly inhibited Recently our group demonstrated theantitumour and antiangiogenic activity of the ethanol extractof Pereiro propolis (P10EE) collected in the district ofGuarda Portugal P10EE affects cell viability of differenttumour cells MDA-MB-231 (breast) and DU145 (prostate)being two of the most sensitive ones but was less cytotoxicagainst nontumour cells and fibroblasts Also it signifi-cantly decreased MDA-MB-231 and DU145 cell prolifera-tion and migration along time with cell cycle changesand increased cell death The significant increase observedin glucose consumption and lactate production could beexplained in MDA-MB-231 by an increased expression ofhypoxia inducible factor-1120572 pyruvate dehydrogenase kinaseglucose transporter 1 lactate dehydrogenase and carbonicanhydrase Furthermore P10EE induced a decrease inHBMECs total biomass and proliferation and decreasedvessel sprouting in the chicken chorioallantoic membrane[23]

5 Conclusions

From ancient to modern times herbs and other plant prod-ucts have been widely used as medicinal agents first in folkmedicine and other activities in many parts of the world andlater developed and improved on a scientific basis into drugsthat are used in the health system Propolis is one of thefew natural products that has maintained its popularity overa long period of time As reviewed here propolis containsa broad spectrum of compounds that may be useful in thetreatment of different pathological conditions In fact there ismuch literature that deals with the in vitro and in vivo biologi-cal properties of propolisThis wide range of bioactivities thecontinuous discovery of new compounds the long history ofpropolis use and its safety profile make propolis a potentialcandidate for drug discovery that may be useful in severalclinical scenarios Nevertheless it is necessary to make aneffort to standardize propolis composition since it seems thatpropolis biological properties and chemical composition notonly are variable but also are strictly linked In our opinionpropolis extracts may be important economically and wouldallow a relatively inexpensive treatment in different diseaseshowever to promote its use in modern medicine it will benecessary to identify and isolate the bioactive compoundsto be tested separately or in combination with other drugsalready available

Drug discovery does not consist only of the isolationof bioactive lead compounds from the natural sources Infact this process continues outside the academic laboratoriesthrough preclinical studies followed by clinical trials Thusdespite the in vitro and in vivo assays which provide newvaluable information on propolis biological properties andmechanisms of action it will be necessary to analyse theeffectiveness of propolis clinically to complement the basicresearch available and to evaluate the potential of propolis inhuman health promotion
