Novel antimalarial therapeutics that target multiple stages of the parasite lifecycle are urgently required to tackle the emerging problem of resistance with current drugs. Here, we describe the optimization of the 2-anilino quinazoline class as antimalarial agents. The class, identified from publicly available antimalarial screening data, was optimized to generate lead compounds that possess potent
迫切需要针对寄生虫生命周期多个阶段的新型抗疟疾疗法,以解决当前药物出现的耐药性问题。在这里,我们描述了2-苯胺基喹唑啉类作为抗疟剂的优化。从可公开获得的抗疟疾筛查数据确定的类别进行了优化,以生成对恶性疟原虫寄生虫具有有效抗疟疾活性的先导化合物,其与已知的抗疟疾,氯喹和甲氟喹相当。在优化过程中,我们定义了活性所必需的功能,并改善了体外代谢和溶解度。所得的铅化合物对恶性疟原虫的多药耐药菌株具有有效的活性。并在无性繁殖的环状期和寄生虫细胞期将寄生虫捕杀。最后,我们显示了在4天的疟疾疾病负担小鼠模型中,这些先导化合物具有口服有效作用。
