title: Mutagenicity of N-nitroso pyridinol carbamate with the Salmonella/mammalian microsome test.
abstract: Pyridinol carbamate was nitrosated to the N,N1-dinitroso derivative and the structure was proved by spectroscopic methods, including chemical ionization mass spectroscopy. By the Ames test, the dinitroso derivative showed a significant dose-dependent mutagenic response with Salmonella typhimurium strains TA 1535 and TA 100; the response became more pronounced in the presence of microsomes. As the dosage of N-nitroso pyridinol carbamate increased, the number of revertant colonies also increased. Pyridinol carbamate was not mutagenic.
