为了鉴定速效、多阶段抗疟药物,通过点击化学(CuAAC)合成了一系列吡啶基乙烯基喹啉 - 三唑类似物。大多数化合物在低微摩尔浓度下对耐药性疟疾Dd2菌株显示出显著的抑制作用。在测试的类似物中,化合物60是最有效的分子,其半数有效浓度(EC50)值为0.04 ± 0.01 μM。我们目前的研究表明,化合物60是一种速效抗疟化合物,它在恶性疟原虫无性生命周期的滋养体阶段表现出阶段特异性作用。此外,化合物60对恶性疟原虫早期和晚期配子体均有活性。从机制角度来看,化合物60作为β - 血红素形成的抑制剂表现出良好的活性。总体而言,我们的研究结果表明,速效药物60针对疟原虫的两个生命阶段,有必要进一步研究吡啶基乙烯基喹啉杂化物作为新型抗疟药物。
To identity fast-acting, multistage antimalarial agents, a series of pyridylvinylquinoline-triazole analogues have been synthesized via CuAAC. Most of the compounds display significant inhibitory effect on the drug-resistant malarial Dd2 strain at low submicromolar concentrations. Among the tested analogues, compound 60 is the most potent molecule with an EC50 value of 0.04 ± 0.01 μM. Our current study indicates that compound 60 is a fast-acting antimalarial compound and it demonstrates stage specific action at the trophozoite phase in the P. falciparum asexual life cycle. In addition, compound 60 is active against both early and late stage P. falciparum gametocytes. From a mechanistic perspective, compound 60 shows good activity as an inhibitor of β-hematin formation. Collectively, our findings suggest that fast-acting agent 60 targets dual life stages of the malarial parasites and warrant further investigation of pyridylvinylquinoline hybrids as new antimalarials.
