Bi-functional conjugates comprised of 4-aminoquinoline and 1,3,5-triazine were synthesized through facile synthetic routes. These compounds were rigorously screened for determination of their antimalarial activity against wild and mutant cultured Plasmodium falciparum. The results disclosed that the conjugates have considerable antimalarial activity against both wild and mutant parasites with marked variation on changing the pattern of substitutions. The observed activity profiles were additionally substantiated by docking studies on both wild and quadruple mutant P. falciparum dihydrofolate reductase thymidylate synthase (pf-DHFR-TS).
通过简便的合成路线合成了由 4-氨基喹啉和 1,3,5-三嗪组成的双功能共轭物。对这些化合物进行了严格筛选,以确定它们对野生和变异培养的恶性疟原虫的抗疟活性。结果表明,这些共轭物对野生寄生虫和变异寄生虫都具有相当强的抗疟活性,而且随着取代模式的改变而发生明显变化。此外,对野生和四重突变的恶性疟原虫二氢叶酸还原酶胸苷酸合成酶(pf-DHFR-TS)进行的对接研究也证实了观察到的活性特征。
