novel compounds derived from diversity-oriented synthesis with activity in multiple stages of the malaria parasite life cycle. Here, we report the optimization of a potent series of antimalarial inhibitors consisting of azetidine-2-carbonitriles, which we had previously shown to target P. falciparum DHODH in a biochemical assay. Optimized compound BRD9185 (27) has in vitro activity against multidrug-resistant
二氢乳清酸脱氢酶(DHODH)是在疟原虫(疟疾的致病原)的原生动物寄生虫中嘧啶生物合成所必需的酶。最近,我们报道了鉴定自源自面向多样性的合成的新型化合物,该化合物在疟疾寄生虫生命周期的多个阶段均具有活性。在这里,我们报告了一系列有效的抗疟疾抑制剂的优化,这些抑制剂由氮杂环丁烷-2-腈组成,我们先前已在生化分析中证明它们靶向恶性疟原虫DHODH。优化的化合物BRD9185(27)对多药耐药的血液阶段寄生虫具有体外活性(EC50 = 0.016μM),在伯氏疟原虫小鼠模型中仅需三剂即可治愈。
