    • The present invention provides nucleoside cyclic 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 pre-cursors 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 cyclic 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 cyclic phosphoramidates of the present invention.
    • 本发明提供了作为RNA依赖性RNA病毒聚合酶抑制剂前体的结构式(I)核苷环状氨基磷酸酯。 这些化合物是RNA依赖性RNA病毒复制抑制剂的前体,可用于治疗RNA依赖性RNA病毒感染。 它们作为丙型肝炎病毒(HCV)NS5B聚合酶抑制剂作为HCV复制抑制剂前体和/或用于治疗丙型肝炎感染的前体特别有用。 本发明还描述了含有这种核苷环状氨基磷酸酯的药物组合物,或者与其它对RNA依赖性RNA病毒感染,特别是HCV感染有活性的试剂组合。 还公开了本发明的核苷环状氨基磷酸酯抑制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。
