Drugs against malaria are losing their effectiveness because of emerging drug resistance. This underscores the need for novel therapeutic options for malaria with mechanism of actions distinct from current antimalarials. To identify novel pharmacophores against malaria we have screened compounds containing structural features of natural products that are pharmacologically relevant. This screening has
由于出现了新的耐药性,抗疟疾药物正在失去效力。这强调了对新颖的疟疾治疗选择的需求,其作用机理与目前的抗疟药不同。为了鉴定针对疟疾的新型药效基团,我们筛选了含有天然药理学相关结构特征的化合物。此筛选已鉴定出具有亚微摩尔抗血浆活性和优异选择性的4-硝基苯乙烯基喹啉(SQ)化合物。SQ表现出不同于当前抗疟疾的细胞作用,对疟原虫的红细胞内生命周期(包括裂殖子入侵)起早期作用。该化合物是一种速效杀虫剂,口服时在啮齿动物疟疾模型中也显示出治疗作用。在这份报告中
