metabolically labile ester/amide function. We then further replaced the oxadiazole ring with a series of five-membered heterocycles and finally combined the most promising structural features. All the new derivatives were tested in vitro for antimalarial as well as antileishmanial activity. We identified two very promising new lead compounds, endowed with submicromolar antileishmanial activity and nanomolar
从先前报道的基于3-Br-异恶唑啉的恶性疟原虫共价抑制剂的结构开始甘油醛 3-磷酸脱氢酶,为了提高它们的代谢稳定性和抗疟活性,我们设计并合成了一系列简化的类似物,其特征是插入恶二唑环作为代谢不稳定的酯/酰胺功能的生物等排替代品. 然后,我们进一步用一系列五元杂环取代了恶二唑环,最终结合了最有希望的结构特征。所有新衍生物都在体外测试了抗疟疾和抗利什曼病活性。我们鉴定了两种非常有前途的新先导化合物,它们分别具有亚微摩尔级抗利什曼原虫活性和纳摩尔级抗疟原虫活性,并且对哺乳动物细胞具有非常高的选择性指数。
