develop new antimalarial drugs. Recent in vivo efficacy improvements of the historical antimalarial ICI 56,780 have been reported, however, with the poor solubility and rapid development of resistance, this compound requires further optimization. A series of piperazine-containing 4(1H)-quinolones with greatly enhanced solubility were developed utilizing structure–activity relationship (SAR) and structure–property
在过去的10至15年中,疟疾死亡人数一直在减少,自2000年以来,全球死亡率下降了47%。尽管世界卫生组织(WHO)建议使用基于青蒿素的联合疗法(ACTs)来对抗疟疾,青蒿素耐药菌株的出现突显了开发新的抗疟药的需要。已经报道了历史上抗疟疾ICI 56,780的近期体内功效改善,但是,由于其较差的溶解度和快速的耐药性,该化合物需要进一步优化。一系列含哌嗪的4(1 H利用结构-活性关系(SAR)和结构-性质关系(SPR)研究开发了溶解度大大提高的喹诺酮类药物。此外,选择了有前途的化合物用于体内筛选研究,以缩小选择范围以进行体内汤普森测试。最后,在常规汤普森试验中,两种含哌嗪的4(1 H)-喹诺酮类药物具有治愈作用,并且还表现出了针对寄生虫肝脏阶段的体内活性。
