Alkoxyanthranilic acid derivatives have been identified to inhibit HCV NS5B polymerase, binding in an allosteric site located at the convergence of the palm and thumb regions. Information from co-crystal structures guided the structural design strategy. Ultimately, two independent structural modifications led to a similar shift in binding mode that when combined led to a synergistic improvement in
已鉴定出烷氧基邻氨基苯甲酸衍生物可抑制 HCV NS5B 聚合酶,与位于手掌和拇指区域会聚处的变构位点结合。来自共晶结构的信息指导了结构设计策略。最终,两种独立的结构修饰导致了结合模式的类似转变,当它们组合时导致效力的协同提高和具有亚微摩尔 HCV NS5B 结合效力的抑制剂的鉴定。
