Mutagenicity of several classes of antitumor agents to Salmonella typhimurium TA98, TA100, and TA92.

The mutagenic activities of antitumor agents, including 5 antibiotics, 19 antimetabolites, 5 alkylating agents, 2 alkaloids, 1 enzyme, and 1 adrenal steroid hormone, were tested on Salmonella tyhimurium TA100, TA98, and TA92. Four of these, busulfan, carbazilquinone, 1-(4-amino-2-methylpyrimidine-5-yl)methyl-3-(2-chloroethyl)-3-nitrosourea hydrochloride, and pipobroman were shown for the first time to be mutagenic. Further, the known mutagenicities of five others, daunomycin hydrochloride, Adriamycin hydrochloride, mitomycin C, 6-mercaptopurine, and cyclophosphamide, were confirmed.
