derivatives, are described. An explanation is given of the differences in carcinogenic activity of the 2-, 7-, and 12-methyl derivatives, consistent with specific molecular orientations for carcinogenesis similar to those deduced for tricycloquinazoline and its derivatives.
取代的二苯并[ b,h ] [1,6]萘啶和取代的[1]苯并吡喃并[3,2 - c ]喹啉-7-环的环化,以及N-羧基邻氨基苯甲酸酐与取代的1,3-的缩合描述了二苯基丙烷-1,3-二酮,然后进行还原环化,明确导致二苯并[ b,h ] [1]苯并吡喃并[2,3,4- de ] [1,6]萘啶和五个异构甲基衍生物。给出了2-,7-和12-甲基衍生物的致癌活性差异的解释,这与致癌作用的特定分子方向一致,类似于对三环喹唑啉及其衍生物的推导。
