In this study, synthesis and docking studies of a series of new benzimidazole derivatives linked to substituted pyrimidines either through the methylenethio linkage or its bioisosteric methylene amino bridge were carried out. All the synthesized compounds were evaluated for their hepatitis C virus (HCV) RNA replication-inhibitory activity. Compounds 4d, 4f, and 4h were found to be more potent than
在这项研究中,进行了一系列新的苯并咪唑衍生物的合成和对接研究,这些衍生物通过亚甲基硫键或其生物等位亚甲基氨基桥与取代的嘧啶连接。评价所有合成的化合物的丙型肝炎病毒(HCV)RNA复制抑制活性。发现化合物4d,4f和4h比VX-950更有效(IC50 / 90为4d = 0.123 / 0.321、4f = 0.145 / 0.345、4h = 0.129 / 0.432,VX-950 = 0.20 / 0.45 µM )和6d(IC50 / 90 = 0.116 / 0.452 µM)所显示的活性与标准品非常相似。化合物4d,4f,4h和6d是有效的HCV RNA复制抑制剂,是进一步研究的良好候选药物。
