The hepatitis C virus (HCV) NS5B polymerase is an attractive target for the development of novel and selective inhibitors of HCV replication. In this paper, the design, synthesis, and preliminary SAR studies of novel inhibitors of HCV NS5B polymerase based on the structure of tegobuvir have been described. The efforts to optimize the antiviral potency and reduce the treatment side effects with respect
丙型肝炎病毒 (HCV) NS5B 聚合酶是开发新型和选择性 HCV 复制抑制剂的有吸引力的靶标。本文介绍了基于替戈布韦结构的新型 HCV NS5B 聚合酶抑制剂的设计、合成和初步 SAR 研究。针对基因型 1b 优化抗病毒效力和减少治疗副作用的努力导致发现了化合物 3,其 EC 50为 1.163 nM 和 CC 50在基于细胞的 HCV 复制子系统测定中 >200 nM。此外,对 hERG 通道的抑制测试显示出比 tegobuvir 有显着改善,化合物 3 的药代动力学特性表明它作为 HCV NS5B 聚合酶的非核苷抑制剂值得进一步研究。
