The discovery of potent thienoimidazole-based HCV NS5A inhibitors is herein reported. A novel method to access the thienoimidazole [5,5]-bicyclic system is disclosed. This method gave access to a common key intermediate (6) that was engaged in Suzuki or Sonogashira reactions with coupling partners bearing different linkers. A detailed study of the structure-activity relationship (SAR) of the linkers
本文报道了基于噻吩并咪唑的有效HCV NS5A抑制剂的发现。公开了一种访问噻吩并咪唑[5,5]-双环系统的新方法。该方法可以访问共同的关键中间体(6),该中间体与带有不同接头的偶联配偶体一起参与Suzuki或Sonogashira反应。对接头的结构-活性关系(SAR)的详细研究表明,对于1a和1b HCV基因型而言,具有线性拓扑结构的芳族接头必须具有很高的效价。具有对苯基接头的化合物20被鉴定为潜在的铅,分别针对基因型1a和1b复制子显示17和8 pM的效力。
