to gain insight into the structure–activity relationships by probing the ability of MMV008138 analogs to inhibit PfIspD recombinant enzyme. Here, we report PfIspD inhibition data for fosmidomycin (FOS) and 19 previously disclosed analogs and report parasite growth and PfIspD inhibition data for 27 new analogs of MMV008138. In addition, we show that MMV008138 does not target the recently characterized
疟疾仍然是世界上最致命的疾病之一,耐药性寄生虫的出现一直是威胁。疟原虫寄生虫利用甲基赤藓糖醇磷酸酯(MEP)途径来合成异戊烯基焦磷酸酯(IPP)和二甲基烯丙基焦磷酸酯(DMAPP),这对于寄生虫的生长至关重要。以前,我们和其他人发现,疟疾框化合物MMV008138靶向于原生质体,并且该化合物对寄生虫的生长抑制作用可以通过补充IPP来逆转。进一步的工作表明,MMV008138靶向2- C-甲基-d酶。MEP途径中的-赤藓糖醇4-磷酸胞苷转移酶(IspD),可将MEP和胞苷三磷酸(CTP)转化为胞苷二磷酸甲基赤藓糖醇(CDP-ME)和焦磷酸。在这项工作中,我们试图通过探索MMV008138类似物抑制Pf IspD重组酶的能力来深入了解结构与活性之间的关系。这里,我们报告Pf的ISPD抑制数据用于膦胺霉素(FOS)和19个以前公开的类似物和报告寄生虫生长和Pf的ISPD抑制数据用于MMV0081
