We studied the metabolism of methyl-n-butyl-nitrosamine (MBN), a carcinogen for the rat esophagus and liver. The 2-, 3- and 4-hydroxy derivatives were identified as new metabolites of MBN. In studies on tissue slices freshly removed from MRC-Wistar rats, MBN metabolism

N-Nitrosodialkylamines are known to be potent indirect-acting mutagens/carcinogens, which are activated by cytochrome P450. The reaction product of N-nitroso-N-methylbutylamine (NMB) with modified Fenton's reagent supplemented with copper salt (Fe²(+)-Cu²(+)-H₂O₂) was reported to be mutagenic in Salmonella typhimurium TA1535 without S9

Metabolic activation may be a key step in determining the tissue specificity of carcinogenic nitrosamines. In previous work, we characterized P450IIE1 (an acetone/ethanol-inducible form of cytochrome P-450) as the major enzyme for the metabolic activation of N-nitrosodimethylamine. In this work

The organic solvents dimethylsulphoxide (DMSO), acetone, ethanol and dimethylformamide inhibited the mutagenic activity of the promutagens dimethylnitrosamine and methylbutylnitrosamine in a higher plant Arabidopsis thaliana. In contrast, the direct-acting mutagens N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) and N-methyl-N-nitrosourea (MNU) were not affected by the

Journal of cancer research and clinical oncology, 106(3), 171-175 (1983-01-01)
The carcinogenic effectiveness of nitrosomethyl-n-butylamine,-n-hexylamine and -n-heptylamine was compared by administration to F344 rats at various concentrations in drinking water and by gavage in oil. Nitrosomethylbutylamine induced only tumors of the upper gastrointestinal tract, and was very toxic. Nitrosomethylhexylamine was
