摘要: Abstract The electrophilic properties of 4-chloro- N -(hydroxymethyl) benzamide as a model compound carbinolamides formed during the metabolic oxidation -methylamides were investigated. 4-Cholo- -(hydroxymethyl)benzamide did not react with nucleophiles such cyanide or glutathione under physiological conditions. In contrast, -(acetoxymethyl)-4-chlorobenzamide yielded cyanomethylamide KCN and S -(chlorobenzamidomethyl) glutathione. Under non-aqueous conditions, reacted ethanethiol, methanol diethylamine in presence base, whereas afford products these These results show clearly that is precursor reactive methyleneimines. 4-Chloro- was biotransformed to species when incubated mouse hepatic microsomes microsomal supernatant acetyl-CoA PAPS generating system. Neither nor its acetate ester mutagenic short term bacterial assay using Salmonella typhimurium . Nevertheless, esters carbinolamides, -(acetoxymethyl)-4-chlorobenzamide, might possess toxic carcinogenic properties.
