A series of potent anthranilic acid-based inhibitors of the hepatitis C NS5B polymerase has been identified. The inhibitors bind to a site on NS5B between the thumb and palm regions adjacent to the active site as determined by X-ray crystallography of the enzyme-inhibitor complex. Guided by both molecular modeling and traditional SAR, the enzyme activity of the initial hit was improved by approximately
已鉴定出一系列强效邻氨基苯甲酸丙型肝炎 NS5B 聚合酶抑制剂。通过酶抑制剂复合物的 X 射线晶体学测定,抑制剂与 NS5B 上拇指和手掌区域之间与活性位点相邻的位点结合。在分子建模和传统 SAR 的指导下,初始命中的酶活性提高了约 100 倍,产生了一系列有效且选择性的 NS5B 抑制剂,IC50 值低至 10 nM。这些化合物也是培养的 HUH7 细胞中 HCV 复制子的抑制剂。
