Some chemicals were profiled for a) the chemical classes b) the presence of structural alerts for carcinogenicity and for protein binding. The relationships between profiles of toxicity data and structural determinants were studied. In addition, the possibility of identifying further Structural Alerts for nongenotoxic carcinogenicity were explored; the information was disseminated in the public domain by donating to the OECD (Q)SAR Toolbox. This database is available on the OECD Website.
