Optimization of a chemical series originating from whole-cell phenotypic screening against the human malaria parasite, Plasmodium falciparum, led to the identification of two promising 2,6-disubstituted imidazopyridine compounds, 43 and 74. These compounds exhibited potent activity against asexual blood stage parasites that, together with their in vitro absorption, distribution, metabolism, and excretion
从全细胞表型筛选针对人类疟疾寄生虫,恶性疟原虫的化学系列的优化导致鉴定了两个有前途的2,6-二取代的咪唑并吡啶化合物43和74。这些化合物显示出对无性血液阶段寄生虫的有效活性,以及它们的体外吸收,分布,代谢和排泄(ADME)特性,在Pf SCID小鼠模型中可在48小时内清除疟原虫的体内寄生虫,转化为体内功效的治疗。
