The present invention provides nucleoside aryl phosphoramidates of structural formula (I) which are precursors to inhibitors of RNA-dependent RNA viral polymerase. These compounds are precursors to 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 nucleoside aryl phosphoramidates 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 nucleoside aryl phosphoramidates of the present invention.
本发明提供了结构式(I)的核苷酸芳基磷酰胺衍生物,它们是RNA依赖性RNA病毒聚合酶抑制剂的前体。这些化合物是RNA依赖性RNA病毒复制的抑制剂前体,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聚合酶抑制剂前体,作为HCV复制抑制剂前体,和/或用于治疗丙型肝炎感染。该发明还描述了包含这种核苷酸芳基磷酰胺衍生物的药物组合物,单独或与其他针对RNA依赖性RNA病毒感染,特别是HCV感染的活性剂结合使用。本发明还揭示了使用这些核苷酸芳基磷酰胺衍生物抑制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。
