Fourteen N-alkyl-N-(ω-carboxyalkyl) nitrosamines related to N-butyl-N-(3-carboxypropyl) nitrosamine, principal urinary metabolite of a potent bladder carcinogen N-butyl-N-(4-hydroxybutyl) nitrosamine, were prepared for the purpose of mainly characterizing urinary metabolites and in part testing their carcinogenic effects in rats. They were N-alkyl-N-(3-carboxypropyl) nitrosamines, N-alkyl-N-(2-carboxyethyl) nitrosamines, and N-alkyl-N-(carboxymethyl) nitrosamines. They were mostly prepared by the permanganate oxidation of the corresponding N-alkyl-N-(ω-hydroxyalkyl) nitrosamines.
制备了 14 种与 N-丁基-N-(3-羧丙基)亚硝胺有关的 N-烷基-N-(ω-羧烷基)亚硝胺,N-丁基-N-(4-羟丁基)亚硝胺是一种强效膀胱致癌物 N-丁基-N-(4-羟丁基)亚硝胺的主要尿液代谢物,其主要目的是确定尿液代谢物的特征,并部分测试它们对大鼠的致癌作用。它们是 N-烷基-N-(3-羧丙基)亚硝胺、N-烷基-N-(2-羧乙基)亚硝胺和 N-烷基-N-(羧甲基)亚硝胺。它们大多是通过相应的 N-烷基-N-(ω-羟基烷基)亚硝胺的高锰酸盐氧化法制备的。
