The indoloquinoline alkaloid cryptolepine 1 has potent in vitro antiplasmodial activity, but it is also a DNA intercalator with cytotoxic properties. We have shown that the antiplasmodial mechanism of 1 is likely to be due, at least in part, to a chloroquine-like action that does not depend on intercalation into DNA. A number of substituted analogues of 1 have been prepared that have potent activities
吲哚喹啉碱生物碱1具有强大的体外抗血浆活性,但它也是具有细胞毒性的DNA嵌入剂。我们已经表明1的抗疟原虫机制可能至少部分是由于不依赖于插入DNA的类似氯喹的作用。已经制备了许多取代的类似物1,它们对恶性疟原虫的氯喹敏感和耐氯喹菌株均具有有效的活性,并且与氯喹共同具有抑制无细胞系统中β-血红素形成的作用。几种化合物还对小鼠伯氏疟原虫表现出活性,最有效的是2,7-二溴隐油菜素8,与未经处理的感染对照相比,在剂量为12.5 mg kg(-1)day(-1)时,其寄生虫抑制率达89%。 ip。
