  Discovery of the First Thumb Pocket 1 NS5B Polymerase Inhibitor (BILB 1941) with Demonstrated Antiviral Activity in Patients Chronically Infected with Genotype 1 Hepatitis C Virus (HCV)

  摘要：

  Combinations of direct acting antivirals (DAAs) that have the potential to suppress emergence of resistant virus and that can be used in interferon-sparing regimens represent a preferred option for the treatment of chronic HCV infection. We have discovered allosteric (thumb pocket 1) non-nucleoside inhibitors of HCV NS5B polymerase that inhibit replication in replicon systems. Herein, we report the late-stage optimization of indole-based inhibitors, which began with the identification of a metabolic liability common to many previously reported inhibitors in this series. By use of parallel synthesis techniques, a sparse matrix of inhibitors was generated that provided a collection of inhibitors satisfying potency criteria and displaying improved in vitro ADME profiles. "Cassette" screening for oral absorption in rat provided a short list of potential development candidates. Further evaluation led to the discovery of the first thumb pocket 1 NS5B inhibitor (BILB 1941) that demonstrated antiviral activity in patients chronically infected with genotype 1 HCV.

  改善 HCV NS5B 聚合酶非核苷变构抑制剂的复制子细胞活性：从苯并咪唑到吲哚支架。

  摘要：

  基于苯并咪唑的丙型肝炎病毒 (HCV) NS5B 聚合酶变构抑制剂被多样化用于各种拓扑相关的支架。用亲脂性吲哚取代极性苯并咪唑核心导致抑制剂在基于细胞的亚基因组 HCV 复制子系统中具有更高的效力。将吲哚支架转移到先前描述的一系列苯并咪唑-色氨酸酰胺中产生了迄今为止在该系列中报告的细胞培养物中最有效的 HCV RNA 复制抑制剂（EC(50) 约 50 nM）。

  Benzimidazole-based allosteric inhibitors of the hepatitis C virus (HCV) NS5B polymerase were diversified to a variety of topologically related scaffolds. Replacement of the polar benzimidazole core by lipophilic indoles led to inhibitors with improved potency in the cell-based subgenomic HCV replicon system. Transposing the indole scaffold into a previously described series of benzimidazole-tryptophan
