incidences of lung tumors were observed in mice fed coal tar in their diet. The principal component of tar that gives rise to DNA-bound adducts in mouse lung was identified as 7H-benzo[c]fluorene (BcF). We now report the synthesis of suspected active metabolites of BcF, specifically the trans-3,4-dihydrodiol of BcF (2), its likely proximate carcinogenic metabolite, and the corresponding anti- and syn-diol
在饮食中饲喂煤焦油的小鼠中肺肿瘤的发生率很高。在小鼠肺中引起DNA结合加合物的焦油的主要成分被鉴定为7H-苯并[c]芴(BcF)。现在,我们报告了BcF的疑似活性代谢产物的合成,特别是BcF的反式3,4-二氢二醇(2),其可能的致癌代谢产物以及BcF的相应的抗二醇和顺式二醇环氧化合物(3和4)。其中环氧环位于伪湾区。假定二醇环氧衍生物(3和4)是BcF的最终致癌代谢产物,可与小鼠肺中的DNA结合。
