urgent requirement for new antimalarial drugs. We previously reported the identification of 4(1H)-pyridones as a novel series with potent antimalarial activities. The low solubility was identified as an issue to address. In this paper, we describe the synthesis and biological evaluation of 4(1H)-pyridones with potent antimalarial activities in vitro and in vivo and improved pharmacokinetic profiles
疟疾仍然是世界上最普遍的寄生虫感染之一,世界上一半的人口面临疟疾风险。耐药疟原虫菌株的传播不断威胁着当前的抗疟疗法,甚至是最新一类
抗疟药(
青蒿素联合疗法,ACTs)的有效性。结果,仍然迫切需要新的
抗疟药。我们先前报道了4(1 H)-
吡啶酮的鉴定为具有有效抗疟疾活性的新系列。低溶解度被认为是需要解决的问题。在本文中,我们描述了4(1 H)-
吡啶酮类在体内和体外均具有强大的抗疟疾活性,并改善了药代动力学。它们的主要结构新颖性是极性基团(例如羟基)的存在,以及亲脂性侧链上的
吡啶取代了亲脂性苯环。
