  new DAAs, with the ultimate goal to provide interferon-free combinations. The RNA-dependent RNA polymerase enzyme NS5B represents one such DAA therapeutic target for inhibition that has attracted much interest over the past decade. Herein, we report the discovery and optimization of a novel series of inhibitors of HCV NS5B, through the use of structure-based design applied to a fragment-derived starting

  丙型肝炎病毒（HCV）是一个主要的全球公共卫生问题。虽然目前的护理标准是一种直接作用的抗病毒 (DAA) 蛋白酶抑制剂，与聚乙二醇干扰素和利巴韦林联合使用，代表了近年来的一项重大进步，但对于提高疗效和耐受性的治疗方式仍然存在未满足的医疗需求. 为实现这些目标，人们继续致力于发现新的 DAA，最终目标是提供无干扰素的组合。RNA 依赖性 RNA 聚合酶 NS5B 代表了一种此类 DAA 抑制治疗靶标，在过去十年中引起了极大的兴趣。在此，我们报告了通过将基于结构的设计应用于片段衍生的起点，发现和优化了一系列新型 HCV NS5B 抑制剂。19 .
