A series of diaryl ether substituted 4-pyridones have been identified as having potent antimalarial activity superior to that of chloroquine against Plasmodium falciparum in vitro and murine Plasmodium yoelii in vivo. These were derived from the anticoccidial drug clopidol through a systematic study of the effects of varying the side chain on activity. Relative to clopidol the most active compounds
已鉴定出一系列二芳基醚取代的4-吡啶酮,其在体外和体内对鼠恶性疟原虫的有效抗疟活性优于氯喹对恶性疟原虫的抗疟活性。这些是通过对侧链变化对活性的影响进行系统研究而从抗球虫药clopidol衍生而来的。相对于氯吡咯醇,最具活性的化合物在体外抑制恶性疟原虫的IC50改善了500倍以上,而在小鼠中相对于针对约氏疟原虫的ED50则提高了约100倍。这些化合物已在其他地方显示出通过抑制细胞色素bc1络合物处线粒体电子传递的作用而选择性发挥作用。
