Nineteen N-alkyl-N-(hydroxy- or oxo-alkyl) nitrosamines structurally related to N-butyl-N-(4-hydroxybutyl) nitrosamine, a potent bladder carcinogen, were synthesized for the purpose of investigating their carcinogenic effects in rats. They are N-alkyl-N-(4-hydroxybutyl) nitrosamines, N-alkyl-(3-hydroxypropyl)-nitrosamines, N-alkyl-N-(2-hydroxyalkyl) nitrosamines, and N-alkyl-N-(2- or 3-oxoalkyl) nitrosamines. They were mostly prepared by the nitrosation of the corresponding N-alkyl-N-(hydroxyalkyl) amines. The nitrosamines with an oxo group were prepared by chromium trioxide oxidation of the corresponding N-alkyl-N-(hydroxyalkyl) nitrosamines with a secondary hydroxyl group.
为研究其在大鼠体内的致癌效应,合成了19种与N-丁基-N-(4-羟基丁基)亚硝胺(一种强效膀胱致癌物)结构相关的N-烷基-N-(羟基或氧代烷基)亚硝胺。这些亚硝胺包括N-烷基-N-(4-羟基丁基)亚硝胺、N-烷基-N-(3-羟基丙基)亚硝胺、N-烷基-N-(2-羟基烷基)亚硝胺以及N-烷基-N-(2-或3-氧代烷基)亚硝胺。它们主要通过相应N-烷基-N-(羟基烷基)胺的亚硝化反应制备。含有氧代基团的亚硝胺则通过铬酐氧化相应的具有次级羟基的N-烷基-N-(羟基烷基)亚硝胺制备。
