Genotoxicity of the phosphoramidate agent tabun (Ga). (Reannouncement with new availability information)
Five mutagenicity tests were performed on Agent GA (Tabun, phosphoramidocyanidic acid, dimethyl-, ethyl ester) as part of a program to demilitarize chemical warfare agents. GA was mutagenic in Salmonella spp. assays with S-9 and it was a direct-acting mutagen to mouse lymphoma cells. GA did not promote unscheduled DNA synthesis in rat hepatocytes; it induced sister chromatid exchanges in mouse cells in vitro but not in vivo. The conclusion that GA is a weakly acting mutagen is supported by the fact that it was mutagenic in only three of the five assays, and that increases in mutagenicity were often less than 2-fold the controls and occurred near toxic levels. Tabun, Agent GA, Phosphoroamidocyanidic acid, Dimethyl-, Ethyl ester, Genotoxicity, Mutagenic assays.
