respectively. Several analogs displayed promising antimalarial activity in vitro against Plasmodium falciparum D6 (chloroquine-sensitive) and W2 (chloroquine-resistant) clones with high selectivity indices versus mammalian cells. The most promising analogs (21-24) also displayed potent antimalarial activity in vivo in a Plasmodium berghei-infected mouse model. Most interestingly, many analogs exhibited promising
我们报告了两个系列 8-喹啉胺的合成、体外抗原虫(针对疟原虫和利什曼原虫)、抗菌、细胞毒性(Vero 和 MetHb 产生特性)以及体内抗疟活性。N1-4-[2-(叔丁基)-6-甲氧基-8-喹啉氨基]戊基}-(2S/2R)-2-氨基取代酰胺(21-33)和N1-[4-(4-乙基) -6-甲氧基-5-戊氧基-8-喹啉氨基)戊基]-(2S/2R)-2-氨基取代酰胺(51-63)由6-甲氧基-8-硝基喹啉和4-甲氧基-2分六步合成分别为-硝基-5-戊氧基苯胺。几种类似物在体外对恶性疟原虫 D6(氯喹敏感)和 W2(氯喹抗性)克隆表现出良好的抗疟活性,与哺乳动物细胞相比具有高选择性指数。最有前途的类似物 (21-24) 在伯氏疟原虫感染的小鼠模型中也显示出有效的体内抗疟活性。最有趣的是,许多类似物对杜氏利什曼原虫前鞭毛体表现出有前景的体外抗利什曼原虫活性,并对一组病原细菌和真菌表现出抗菌活性。与伯氨喹相比,几种类似物,尤其是
