    摘要: The present invention is directed to compounds, compositions and methods for treating or preventing viral infections using nucleoside analog monophosphate prodrugs. More specifically, HCV, Norovirus, Saporovirus, Dengue virus, Chikungunya virus and Yellow fever in human patients or other animal hosts. The compounds are certain 2,6-diamino 2-C-methyl purine nucleoside monophosphate prodrugs and modified prodrug analogs, and pharmaceutically acceptable, salts, prodrugs, and other derivatives thereof. In particular, the compounds show potent antiviral activity against HCV, Norovirus, Saporovirus, Dengue virus, Chikungunya virus and Yellow fever. This invention teaches how to modify the metabolic pathway of 2,6-diamino 2′-C-methyl purine and deliver nucleotide triphosphate(s) to polymerases at heretofore unobtainable therapeutically-relevant concentrations.
