Mutagenicity of some benzidine congeners and their N-acetylated and N,N'-diacetylated derivatives in different strains of Salmonella typhimurium.

The Ames Salmonella/microsome test was used to compare the mutagenic response of Salmonella typhimurium TA100, TA98, TA1538, and TA1535 to 12 benzidine derivatives, ie, benzidine, 3,3'-dimethoxybenzidine, 3,3'-dimethylbenzidine, 3,3'-dichlorobenzidine, and the corresponding N- and N,N'-diacetylated derivatives. With a few exceptions, the mutagenic response to this series of compounds varied in the order TA98 greater than TA1538 greater than TA100 greater than TA1535 = 0, and the N-monoacetylated derivatives were more mutagenic than either the parent diamines or the N,N'-diacetyl derivatives. The relative mutagenicities of the parent amines for TA98 were 3,3'-dichlorobenzidine much greater than 3,3'-dimethoxybenzidine greater than benzidine greater than 3,3'-dimethylbenzidine.[1]
