Toxicity Database
- Oracle format (Isentris, ISIS access via RCG)
- Full data content of RTECS
- comprehensive coverage of compounds with reported toxic properties
- 170K chemical substances
- chemical structures can be drawn for >95% of records
- 100K drugs or drug development compounds
- all toxicity data associated with original reference
Toxicity is a structure-searchable bioactivity database of over 150,000 toxic
chemical substances. An Oracle-based system accessible through
Isentris, ISIS/Host
or DiscoveryGate,
Toxicity contains data from in vivo and in vitro studies of acute
toxicity, mutagenicity, skin and eye irritation, tumorigenicity and
carcinogenicity, reproductive effects and multiple dose effects. Information
covered includes species of organism studied, tissue studied, route of
administration, dose, endpoint, toxic effects descriptors, severity of response,
CAS Registry Numbers, Beilstein Registry Numbers, chemical names and synonyms,
molecular formula and molecular weight. The Toxicity database includes
references to the original publications reporting the toxicity data and to
relevant review articles when applicable.
Coverage:
1902 - present.
Data is abstracted from over 2,950 worldwide sources, including: scientific
journals, conference proceedings, symposia reports, reviews, and more. MDL
obtains the data found in Toxicity from the Registry of Toxic Effects of
Chemical Substances (RTECS) database. The Toxicity database is updated
quarterly.
Focus:
Toxic properties of chemical substances.
Drugs and drug development compounds constitute 65% of the substances covered.
The remainder consists of agrochemicals, industrial and petrochemicals,
plastics, flavors and fragrances, plant and animal extracts, inorganic
compounds, organometallics, and others.
Toxicity can also be used in conjunction with the Metabolite
database; the ISIS Toxicity Finder, and the Metabolite Browser; links are based
upon chemical structure. While the scientist is browsing either database, and a
structure displays that is registered to both Toxicity and Metabolite, a single
click enables transfer between the databases to view relevant toxicity and
biotransformation data.

You also can download a sample file (tox.zip) in ISIS/Base format with a few hundred entries. This file is 1.2 MB. Unzip all files into one directory and open the database with your copy of ISIS/Base. ISIS/Base is not included in this file. You need to own a copy of ISIS/Base to use the file.
