Genetic activity profiles of anticancer drugs

The results from short-term tests for genetic and related effects, abstracted from the open literature for 36 anticancer drugs, are examined in this review. Data for 27 of these agents are available in the EPA/IARC Genetic Activity Profile (GAP) database. Data summaries, including data listings and activity profiles, are presented for nine anticancer drugs added to the GAP database for this analysis. Genetic toxicity data from the recent literature are included for the additional agents to provide a broader representation of the categories of drugs being evaluated. These categories, based on the chemical mode of action, are covalent and noncovalent DNA-binding drugs, topoisomerase II inhibitors, antimetabolites, mitotic spindle inhibitors, and drugs which affect endocrine function. The qualitative data for all 36 drugs are summarized in this report and findings are presented from pair-wise matching of genetic activity profiles, based on test results in common, for some chemical analogs. The significance of germ cell test results for some of these drugs and their implication in assessing risk of heritable genetic disease are discussed.
