4-aminoquinoline-piperonyl-pyrimidine hybrids were synthesized with the aim of identifying compounds with enhanced antimalarial activity. All the synthesized molecules were evaluated in vitro against cultured Plasmodium falciparum W2 and D6 strains and exhibited potent antiplasmodial activities with IC50 values in the range of 0.02-5.16 μM. Out of the 22 synthesised hybrids, 12 were found to be better (up
为了鉴定具有增强的抗疟活性的化合物,合成了一系列的4-氨基喹啉-哌啶基-嘧啶杂化物。所有合成的分子在体外针对培养的恶性疟原虫W2和D6菌株进行了评估,并显示出有效的抗疟原虫活性,IC50值在0.02-5.16μM范围内。在22种合成的杂种中,发现有12种比氯喹(CQ)更好(活性高达八倍),特别是对恶性疟原虫抗CQ的W2菌株,对哺乳动物细胞没有明显的细胞毒性。机理研究表明,这些化合物与血红素结合,计算对接研究表明Pf-DHFR活性位点内有良好的对接相互作用。
