Abstract
The N-nitro derivatives of secondary alpha-amino acids, viz., 1-nitroproline (1a) (L and D), 1-nitro-DL-pipecolic acid (2a), and N-nitrosarcosine (3a), were prepared by the oxidation of the corresponding nitrosamino acids with peroxytrifluoroacetic acid. These nitramino acids (1a-3a) were not active against Escherichia coli, Candida albicans, Pseudomonas aeruginosa, or Mycobacterium smegmatis, and 1a and 2a did not show mutagenic activity in a Salmonella typhimurium TA-100 system, with or without added rat liver 9000g supernatant fraction. The marginal mutagenicity of 3a in this system suggests that additional work should be done to assess its carcinogenic-mutagenic potential.
