promising multi-stage activity against different strains of P. falciparum. It was successfully synthesized via a retrosynthetic approach. Subsequently, twenty-one new derivatives were prepared and tested for their in vitro activity against blood stages of the NF54 strain of P. falciparum. Several insights into structure-activity relationships were revealed. The antiplasmodial activity and cytotoxicity of
来自疟疾风险药物盒项目的 2-苯氧基苯甲酰胺1已显示出针对不同恶性疟原虫菌株的多阶段活性。它是通过逆合成方法成功合成的。随后,制备了 21 种新衍生物并测试了它们对恶性疟原虫NF54 菌株血液阶段的体外活性. 揭示了对结构-活性关系的一些见解。化合物的抗疟原虫活性和细胞毒性在很大程度上取决于苯胺基部分结构的取代模式以及取代基的大小。二芳基醚部分结构对活性有进一步影响。此外,计算了几个物理化学和药代动力学参数(log P、log D 7 . 4和配体效率)或通过实验确定(被动渗透性和 CYP3A4 抑制)。的叔丁基-4- 4- [2-(4-氟苯氧基)-3-(三氟甲基)苯甲酰氨基]苯基}哌嗪-1-羧酸叔丁酯具有针对高抗疟原虫活性的恶性疟原虫NF54(Pf的NF54 IC 50= 0.2690 µM) 和非常低的细胞毒性(L-6 细胞 IC 50 = 124.0 µM),从而获得了 460 的

New Derivatives of the Multi-Stage Active Malaria Box Compound MMV030666 and Their Antiplasmodial Potencies
MMV’s Malaria Box compound MMV030666 shows multi-stage activity against various strains of Plasmodium falciparum and lacks resistance development. To evaluate the importance of its diarylether partial structure, diarylthioethers and diphenylamines with varying substitution patterns were prepared. A number of evident structure-activity relationships were revealed. Physicochemical and pharmacokinetic
