Mutagenicity of some monoaromatic hydroxamic acids. 1985

C I Wei, and M D Cohen, and D D Swartz, and S Y Fernando, and M D Corbett

The mutagenicity of some monoaromatic hydroxamic acids was tested in the presence and absence of rat liver S-9 with Salmonella typhimurium tester strains TA98 and TA100. Of the five N-(chlorophenyl)-substituted hydroxamic acids and seven N-arylformohydroxamic acids tested, 2 of the first and 4 of the latter series were mutagenic to both strains upon metabolic activation. None of the four N-acetyl-type hydroxamic acids was mutagenic to either strain, even upon activation. Because some of the N-acetyl-derived hydroxamic acids were inactive, whereas the same aromatic nucleus possessing a formyl group displayed significant activity, a consideration of the nature of the aryl group in hydroxamic acid mutagenicity is important.
