A series of novel N-substituted 4-aminoquinoline-pyrimidine hybrids have been synthesized via simple and economic route and evaluated for their antimalarial activity. Most compounds showed potent antimalarial activity against both CQ-sensitive and CQ-resistant strains with high selectivity index. All the compounds were found to be non-toxic to the mammalian cell lines. The most active compound 7b was
已经通过简单且经济的途径合成了一系列新颖的N-取代的4-氨基喹啉-嘧啶杂化物,并对其抗疟活性进行了评估。大多数化合物对CQ敏感和CQ耐药菌株均显示出强大的抗疟疾活性,且具有较高的选择性指数。发现所有化合物对哺乳动物细胞系无毒。使用紫外分光光度计分析最具活性的化合物7b的血红素结合活性。发现化合物与血红素相互作用,并使用工作图确定化合物与血红素之间以1:1的化学计量比形成络合物。还通过分子对接研究在野生型Pf-DHFR-TS和四倍突变体Pf-DHFR-TS的结合位点研究了这些杂种的相互作用。
