T Gichner et al.
Mutagenesis, 1(2), 107-109 (1986-03-01)
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
Nozomi Tsutsumi et al.
Bioorganic & medicinal chemistry, 18(23), 8284-8288 (2010-10-30)
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
T Koreeda et al.
Anticancer research, 19(5B), 4139-4143 (2000-01-11)
The inhibitory effect of a synthetic retinoid, ethyl alltrans-9-(4-methoxy-2, 3, 6-trimethyl-phenyl)-3, 7-dimethyl-2, 4, 6, 8-nonatetraenoate (Tigason), on esophageal carcinogenesis in F344 rats induced by N-nitroso-N-methylbutylamine (NMBA) was evaluated. The animals were given NMBA daily in their drinking water for 21
P P Roller et al.
IARC scientific publications, (41)(41), 199-208 (1982-01-01)
Electron-impact mass spectra of N-nitrosomethyl-n-butylamine, 5 of its specifically deuterated anologs and its methyl-n-hexyl and methyl-n-octyl homologs have been examined. Hydrogen abstraction by the nitrosamino moiety dominates the rearrangement ions, especially at low ionization energy. All compounds exhibited the (M-OH)+
T Kawanishi et al.
Cancer letters, 20(2), 157-164 (1983-09-01)
The effect of phenobarbital (PB) and 3-methylcholanthrene (MC) pretreatment on dealkylations of N-nitrosodimethylamine (NDMA), N-nitrosomethylbutylamine (NMBuA) and N-nitrosomethylbenzylamine (NMBeA) was investigated in rat hepatic microsomes. PB increased the demethylation and the debutylation of NMBuA and the debenzylation of NMBeA. MC
