synthesis, and biological investigation of novel antimalarial agents with low potential to develop resistance and structurally based on a highly conjugated scaffold. Starting from a new hit, the designed modifications were performed hypothesizing a specific interaction with free heme and generation of radical intermediates. This approach provided antimalarials with improved potency against chloroquine-resistant
疟疾是贫困地区的主要健康问题,在这些地区,人们迫切需要以负担得起的价格购买新的抗寄生虫药。我们在此报告了新型抗疟疾药物的设计,合成和生物学研究,这些药物具有发展抗药性的低潜力,并且在结构上基于高度偶联的支架。从新的命中开始,进行设计的修饰,假设与游离血红素发生特定的相互作用并产生自由基中间体。与已知药物相比,该方法为抗疟药提供了增强的抗氯喹抗疟原虫能力。确定了许多结构-活性关系(SAR)趋势,在合成的类似物中,吡咯烷基甲基亚芳基和咪唑衍生物5r,5t,发现8b和8b是新系列中最有效的抗疟药。研究了新化合物的作用机理,并评估了它们的体内活性。
