while carrying out rationally directed low-throughput screening of potential antimalarial agents as part of an effort directed by the World Health Organization. Here we report the design, synthesis, and preliminary pharmacologic characterization of a series of analogues of 4-oxo-3-carboxyl quinolones. These studies indicate that the series has good potential for preclinical development.
疟疾是非洲,亚洲和美洲的热带和亚热带地区的地方病。耐多药性恶性疟原虫的流行日益增加,因此不断需要开发新的抗疟药。鉴于此,特别感兴趣的是未暴露寄生虫的新型支架。最近,瑞士热带研究所的工作人员发现了两种新型的对恶性疟原虫的红细胞内阶段有活性的4-氧代-3-羧基喹诺酮类药物。同时根据世界卫生组织的指导,对潜在的抗疟药进行合理的定向低通量筛选。在这里,我们报告一系列4-氧代-3-羧基喹诺酮类似物的设计,合成和初步药理学表征。这些研究表明该系列药物在临床前开发方面具有良好的潜力。
