[formula: see text] A new benzo[c]phenanthridine alkaloid, 7-hydroxynitidine, was synthesized by a novel synthetic procedure. The cytotoxic activity of this compound against HeLa S3 cells was strong, but not greater than those of its mother compounds, nitidine and NK109. We also synthesized other 9-oxygenated benzo[c]phenanthridine alkaloids, 7-methoxynitidine, 9-demethylnitidine, nitidine, and fagaronine
通过一种新的合成方法合成了一种新的苯并[c]菲啶生物碱7-羟基亚硝胺。该化合物对HeLa S3细胞的杀伤活性很强,但不大于其母体化合物nitidine和NK109。我们还合成了其他9-氧化的苯并[c]菲啶生物碱,7-甲氧基亚硝啶,9-去甲基亚硝胺,亚硝胺和黄酮碱,并测试了它们的细胞毒活性。这些结果表明7-羟基增强了抗肿瘤活性,而8或9-羟基减弱了这种活性。
