antimalarials are needed to support the renewed eradication agenda. We have discovered a novel antimalarial acridone chemotype with dual-stage activity against both liver-stage and blood-stage malaria. Several lead compounds generated from structural optimization of a large library of novel acridones exhibit efficacy in the following systems: (1) picomolar inhibition of in vitro Plasmodium falciparum blood-stage
疟疾仍然是当今世界上最致命的疾病之一。需要新的化学预防和化学抗疟药来支持新的根除议程。我们发现了一种新型的抗疟疾cri啶酮化学型,具有针对肝和血液阶段疟疾的双重阶段活性。从新的a啶酮的大型文库的结构优化产生的几种先导化合物在以下系统中显示出功效:(1)皮摩尔抑制体外恶性疟原虫血液阶段生长对多药耐药性寄生虫的抑制;(2)在约氏红细胞疟原虫鼠疟疾模型中口服后的疗效;(3)预防伯氏疟原虫子孢子体外诱导的人肝细胞发育;(4)保护小鼠体内由伯氏疟原虫子孢子诱导的感染。这项研究首次提出了cri啶酮化学型肝阶段抗疟活性。本文介绍了设计,化学,结构-活性关系,安全性,代谢/药代动力学研究和机理研究的详细信息。
