series of novel 1, 3, 4-oxadiazole neuraminidase inhibitors (6a-6l) were designed and synthesized and their inhibitory activities of NA was tested in vitro. The results displayed that compound 6d exerts the best inhibitory activity (IC50 = 0.027 µM), which was obviously lower than that of oseltamivir carboxylate (OSC) (IC50 = 0.082 µM). Molecular docking analysis showed that the 1, 3, 4-oxadiazole heterocycle
神经氨酸酶(NA)是开发抗流感病毒药物的重要靶点。含有1,3,4-恶二唑杂环的化合物具有良好的生物活性,已被证明在抗菌、抗病毒药物中有广泛的应用。本文设计合成了一系列新型1, 3, 4-恶二唑神经氨酸酶抑制剂( 6a - 6l ),并在体外测试了其对NA的抑制活性。结果表明,化合物6d的抑制活性最好(IC 50 = 0.027 µM),明显低于羧酸奥司他韦(OSC)(IC 50 = 0.082 µM)。分子对接分析表明,1, 3, 4-恶二唑杂环在化合物6d中起着至关重要的作用,它可以在NA S1位点与关键的精氨酸三联体(Arg118、Arg292和Arg 371)相互作用。6d的良好功效也可能归因于取代的苯胺环延伸到 150 腔。理论和实验结果可为新型抗流感药物的开发提供参考。
