The present invention provides fluorinated pyrrolo[2,3,d]pyrimidine nucleoside compounds which are inhibitors of RNA-dependent RNA viral polymerase. These compounds are inhibitors of RNA-dependent RNA viral replication and are useful for the treatment of RNA-dependent RNA viral infection. They are particularly useful as precursors to inhibitors of hepatitis C virus (HCV) NS5B polymerase, as precursors to inhibitors of HCV replication, and/or for the treatment of hepatitis C infection. The invention also describes pharmaceutical compositions containing such fluorinated pyrrolo[2,3-d]pyrimidine nucleoside alone or in combination with other agents active against RNA-dependent RNA viral infection, in particular HCV infection. Also disclosed are methods of inhibiting RNA-dependent RNA polymerase, inhibiting RNA-dependent RNA viral replication, and/or treating RNA-dependent RNA viral infection with the fluorinated pyrrolo[2,3-d]pyrimidine nucleoside of the present invention.
本发明提供了一种氟代吡咯并[2,3,d]嘧啶核苷化合物,其是RNA依赖性RNA病毒聚合酶的抑制剂。这些化合物是RNA依赖性RNA病毒复制的抑制剂,可用于治疗RNA依赖性RNA病毒感染。它们特别适用于作为丙型肝炎病毒(HCV)NS5B聚合酶抑制剂的前体,作为HCV复制抑制剂的前体,和/或用于治疗丙型肝炎感染。该发明还描述了含有这种氟代吡咯并[2,3-d]嘧啶核苷单独或与其他对RNA依赖性RNA病毒感染,特别是HCV感染活性的药物组合物。还公开了使用本发明的氟代吡咯并[2,3-d]嘧啶核苷抑制RNA依赖性RNA聚合酶,抑制RNA依赖性RNA病毒复制和/或治疗RNA依赖性RNA病毒感染的方法。
