proximate carcinogenic metabolites. Conversion of 2a to the bay region anti-diol epoxide derivative 3a, its putative ultimate carcinogenic metabolite, is also reported. The related diol epoxide derivative of 2b could not be prepared due to its chemical instability. Tumorigenicity assays confirm that 1b and 2b are potent carcinogens on mouse skin, while 1a and 2a are only relatively weakly active. The diol
描述了苯并[a,j]蒽和7,14-二甲基苯并[a,j]蒽(1a和1b)的反式3,4-二氢二醇衍生物(2a和2b)的合成,涉及它们的潜在致癌代谢物。还报道了将2a转化为海湾地区的抗二醇环氧衍生物3a(其最终的致癌代谢产物)。由于其化学稳定性,无法制备相关的2b二醇环氧衍生物。致瘤性试验证实1b和2b是小鼠皮肤上的强致癌物,而1a和2a的活性相对较弱。二醇环氧化合物3a显示出比其二氢二醇前体2a显着更高的致瘤性。这些发现与海湾区域二醇环氧代谢物是这些烃的活性致癌形式的假说相符。
