of quaternary sanguinarine chloride. 1-Bromo-2-bromomethyl-3,4-alkylenedioxy benzenes and 6,7-alkylenedioxynaphthalen-1-amines were synthesized first. Reactions to construct the target compounds with these two series of synthons involved alterations on a published method for synthesizing 2,3,7,8-tetraoxygenated derivatives of benzo[c]phenanthridinium, substituting benzyl bromides for benzoic aldehydes
开发了一种方法合成2,3:7,8-二(亚烷基二氧基)-季铵盐氯化萘的类似物。首先合成了1-溴-2-溴甲基-3,4-亚烷基二氧基苯和6,7-亚烷基二氧基萘-1-胺。用这两个系列合成子构建目标化合物的反应涉及对已发表的合成苯并[ c ]菲啶鎓的2,3,7,8-四加氧衍生物,用苄基溴取代苯甲醛,延长自由基环化时间的方法的改变,并用甲酸和NaBH 4进行N-甲基化。与阳性化合物相比,所有目标化合物对癌细胞系的体外生长抑制活性均相同或更好。产生了与目标化合物的细胞毒性和亲脂性有关的结构活性关系。
