The 4-substituted 3-amino-1,2,5-oxadiazole 1 from the Malaria Box Project of the Medicines for Malaria Venture foundation shows very promising selectivity and in vitro activity against Plasmodium falciparum. Within the first series of new compounds, various 3-acylamino analogs were prepared. This paper now focuses on the investigation of the importance of the aromatic substituent in ring position 4
来自疟疾风险药物基金会疟疾盒项目的 4-取代 3-氨基-1,2,5-恶二唑 1 显示出非常有前景的对抗恶性疟原虫的选择性和体外活性。在第一批新化合物中,制备了各种 3-酰氨基类似物。本文现在重点研究环4位芳香族取代基的重要性。阐述了许多新的结构-活性关系,表明抗疟原虫活性和选择性强烈依赖于4-苯基部分的取代模式。此外,计算了与药物开发相关的物理化学参数(logP和配体效率)或通过实验确定(CYP3A4抑制和水溶性)。N-[4-(3-乙氧基-4-甲氧基苯基)-1,2,5-恶二唑-3-基]-3-甲基苯甲酰胺 51 对恶性疟原虫氯喹敏感菌株 NF54 (PfNF54 IC50 = 0.034 µM),产生非常有前景的选择性指数 1526。
