A novel class of HCV NS5B RNA dependent RNA polymerase inhibitors containing 2,3,4,9-tetrahydro-1H-carbazole and 1,2,3,4-tetrahydro-cyclopenta[b]indole scaffolds were designed and synthesized. Optimization of the aromatic region showed preference for 5,8-disubstitution pattern in both the scaffolds examined while favoring the n-propyl moiety for the C-1 position. 1,2,3,4-tetrahydro-cyclopenta[b]indole
设计并合成了一类新型 HCV NS5B RNA 依赖性 RNA 聚合酶抑制剂,其中含有 2,3,4,9-四氢-1H-咔唑和 1,2,3,4-四氢-环戊并[b]吲哚支架。芳族区域的优化显示出对所检查的两种支架中的 5,8-二取代模式的偏好,同时有利于 C-1 位置的正丙基部分。1,2,3,4-四氢-环戊二烯[b]吲哚支架比相应的 2,3,4,9-四氢-1H-咔唑和类似物 36 对 HCV NS5B 酶的 IC50 为 550 nM。
