title: Application of the Salmonella typhimurium microsome test to the study of 25 drugs belonging to 5 chemical series.
abstract: 25 active-principle forms of pharmaceutical drugs belonging to 5 chemical series have been tested for mutagenic activity. To screen these drugs we used the Salmonella typhimurium assay on 5-histidine-requiring strains, with and without microsomal activation. Only the 3 nitroimidazole derivatives were mutagenic for strains TA100, TA1535 and TA98.
