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
B Ludeke et al.
IARC scientific publications, (105)(105), 286-293 (1991-01-01)
Aliphatic methylalkylnitrosamines with a chain length of three to six carbon atoms are powerful oesophageal carcinogens in rats and have been shown to methylate target organ DNA preferentially. This class of carcinogens is efficiently metabolized not only in the oesophageal
E Suzuki et al.
Japanese journal of cancer research : Gann, 76(3), 184-191 (1985-03-01)
In order to compare the extents of metabolic alpha-hydroxylation of the two alkyl groups in unsymmetrical N-nitrosodialkylamines, N-nitroso-N-alkylbutylamines (alkyl = methyl, ethyl, propyl, butyl, and amyl) were incubated with liver microsomes prepared from phenobarbital- or polychlorinated biphenyl (PCB)-treated and untreated
W Lijinsky et al.
Carcinogenesis, 1(2), 157-160 (1980-02-01)
Nitrosomethyl-n-butylamine and its derivatives, labeled with deuterium in the methyl group or at the alpha position of the butyl group, were given to rats in drinking water at equimolar doses for approximately 20 weeks. Two concentrations were used, 16 mg/l
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
