What is DiscoveryGate? A web-based portal to 17 premier complementary databases and
reference works in Chemistry More than 21 million compounds More than 14 million reactions More than 550 million searchable facts & data as reported in
literature Allows one-query access to over synthesis, bioactivity, physical
property and sourcing databases. Links to over 15,000 journals and patent archives Designed to increase the productivity of drug discovery process Unlimited access 24/7

New license will include access to full Beilstein database
Click to open Pharmacological and Ecological data (5 fields)
Current license provided access to Beilstein Abstracts
New license provides access to full Beilstein database
Click to open Pharmacological and Ecological data (>100 fields)
7
Search structures and reactions
Select a database and perform a structure and property search
Returns data from multiple databases with a single search
Click directly into primary databases for more detail
8
Indexed relationships shown directly
This compound found in 11 databases Click any link to see detailed record(s)
9
Extend research to the full text Get better value from existing
subscriptions by linking automatically from citations to corresponding full text and patents.
Librarians can: Manage links on DiscoveryGate
or Point to internal library link resolver
• Users can export references to Reference Management tools such as EndNote
• All bibliographic AND patent references are hyperlinked
10
Collect, organize, and share dataDiscoveryGate allows scientists to create and share custom reports with data extracted from the literature
14
MDL Database Browser (DBB) Each tab has its
default page and function:
Queries tab – for formulation & executing query
Results tab – displays hit list and results of your query
Reports tab – for creating reports of your searches.

Search Types
Exact : Search for substances that match your structural query exactly.Include Tautomers : Search for tautomers, and also for structures with different charges and different
isotopes. Include Isomers : Search for stereoisomers (all R and S orientations, all E & Z configurations and so
on). Include Salts : Search for substances that include different salts. Substructure : Search for substances that contain your query wholly embedded within them.Similarity : Search for substances that are structurally similar to your query.

DIY Exercise 21. Conduct an exact match search for
beta-aminopyridine in the MDL Compound Index.
2. View the results
3. Search for compounds that contain the beta-aminopyridine substructure, including isomers, and have molecular weight less than 150.
4. View the results. How do they differ from the results from the exact match search?
21
Data Searching in Individual Databases Each database has its own
predefined search forms. Search forms are stored in
“Easy Data Search” folder
22
Each database has its default query form
Each database has a defined default query form. CrossFire Beilstein and CrossFire Gmelin has predefined forms stored in the
Easy Data Search The forms can be modified.
25
DIY Exercise 3 – Acyclovir in Beilstein Acyclovir, CAS number 59277-
89-3 Do two searches: 1st by name,
then another search by CAS number
Compare the results NN

“BIO” label
The “BIO” label indicates that the compound has pharmacological or toxicological information associated with it.
27
Creating a report In results tab, click on
“copy to report” Specify range of
records to copy to report
Check “view report now”
A report will be a copy of your selected results without the hyperlinks.
28
DIY Exercise 4 – Search ACD database for compound with CAS Registry
number 719-64-2. View suppliers and prices for the compound.
Make a report of the prices.
Conduct a name search for “Atrazine” in the CrossFire Beilstein Database.
View pharmacological data for one compound; retrieve one of the literature references.

Reaction Searching 2 groups of reactions
databases: CrossFire Beilstein and Synthetic Methodology Information
You can select individual databases under Synthetic Methodology Information.

Setting up DiscoveryGate Download the DiscoveryGate installer
http://www.discoverygate.com/DiscoveryGate23sp2sr1.exe Install it
make sure you have administrative privileges and that all IE windows are closed. Otherwsie the install
wizard will abort. Re-open IE, click OK when prompted for Java update. Unblock site in pop-up blocker
35
Setting up DiscoveryGateStep 1 – Run the DiscoveryGate installer Go to www.discoverygate.com Download the DiscoveryGate installer Make sure you have administrative rights to the
machine Run DiscoveryGate installer (All other IE windows
must be closed). Installer will automatically close IE when installation
has completed.
36
Setting up DiscoveryGate (contd)Step 2 --- Have the correct Java Runtime Environment Relaunch IE and go to URLwww.discoverygate.com JAVA update will run automatically if you do not have
the appropriate version. The structure search box appears clear if you have the
correct Java Runtime Environment
37
Setting up DiscoveryGate (contd)Step 3 --- Disable Pop-up Blocker Double click on application
“Search Database” If you get a “pop-up blocked”
message, right click on the yellow bar on top and select “always allow…”
Click “Yes” when prompted
