ISSCAN: Istituto Superiore di Sanita, “CHEMICAL CARCINOGENS: STRUCTURES AND EXPERIMENTAL DATA”
Brief Description: This database originates from the experience of researchers of the Environment and Primary Prevention Department in the field of structure-activity relationships (SAR), aimed at developing models which theoretically predict the carcinogenicity of chemicals. A portion of the chemicals has been the subject of carcinogenicity classification by various Regulatory Agencies and Scientific Bodies. The database has been specifically designed as an expert decision support tool and includes these carcinogenicity classification "calls" to guide the application of SAR approaches.

Resources of Carcinogenicity Data:
CPDB (Berkeley Carcinogenic Potency DataBase); TOXNET CCRIS (database CCRIS from the cluster of toxicological databases TOXNET); NTP (National Toxicology Program; the Technical Report number is also provided); IARC (International Agency for Research on Cancer); SOC (Survey of Compounds which have been tested for Carcinogenic Activity, CD-ROM Version 4.0, GMA Industries Inc.); EINECS (European Inventory of Existing Commercial Chemical Substances).
Data Fields of Particular Interest:
Carcinogenicity results in the four experimental groups most commonly used for the cancer bioassay:
Rat_Male_Canc
Rat_Female_Canc
Mouse_Male_Canc
Mouse_Female_Canc3 = carcinogen
2 = equivocal
1 = noncarcinogen
Rat_Male_NTP
Rat_Female_NTP
Mouse_Male_NTP
Mouse_Female_NTPCE = Clear Evidence
SE = Some Evidence
EE = Equivocal Evidence
NE = No Evidence
DSSTox Note: Since this database has been developed for particular usage in SAR modeling, it includes what we term "simplified to parent" forms of all chemical structures, i.e. no salts or complexes represented as such, and no inorganics or organometallics. The database includes a subset of DSSTox Standard Chemical Fields but does not include explicit stereochemistry in the 2D chemical representations.
