metabolism. These analogues were synthesized and found to exhibit notable in vitro antimalarial activity. Compounds 25 and 27 were the most active of the analogues. In vitro metabolism studies indicated susceptibility of the analogues to hepatic metabolism. There was also evidence of primary glucuronidation for analogues 24–27. Presumed cis–trans isomerism of 12, 22, and 23 under in vitro metabolism assay
先前报道的抗疟杂化化合物8b和12 的类似物被提出,目的是鉴定具有改善的溶解度和保留抗疟效力的化合物。计算机表征预测类似物的溶解度提高,特别是在低 pH 值下;它们保留了可接受的预测渗透性特性,但预计易受肝脏代谢的影响。这些类似物被合成并发现表现出显着的体外抗疟活性。化合物25和27是活性最强的类似物。体外代谢研究表明类似物对肝脏代谢的敏感性。也有类似物初级
葡萄糖醛酸化的证据24– 27 . 的推定顺反异构12,22,和23下在体外代谢试验条件,也观察到,在本质和异构体之间观察到的代谢速率的差异。生化研究强烈表明抑制血红素形成是这些类似物的主要作用机制。
