title: Mutagenicity of aminophenyl and nitrophenyl ethers, sulfides, and disulfides.
abstract: The mutagenic activity of several aromatic amines and aromatic nitro compounds related to 4,4'-methylenedianiline towards Salmonella typhymurium tester strains TA100 and TA98 was evaluated. The heteroatomic analogs of 4,4'-methylenedianiline which include aminophenyl and nitrophenyl ethers, sulfides and disulfides were assayed in the presence of rat-liver homogenate. The relative mutagenic response of these analogs indicated the following order of activity, --S-- greater than --O-- greater than --CH2--CH2-- greater than or equal to --S--S--. In both tester strains 4-aminophenylsulfone was inactive with and without microsomal activation. The p-nitrophenyl ethers, sulfides and disulfides were relatively strong mutagens without microsomal activation towards TA100. While 4-nitrophenyldisulfide was found to possess significantly different mutagenic activity than 4-nitrothiophenol in TA98, 4-AMINOPHENYl disulfide has similar mutagenic properties to 4-aminothiophenol in both tester straains TA100 and TA98.
