The present invention is made to fulfill the foregoing need. Since most of antiHN nucleosides are 2′,3′-dideoxynucleosides that have been proved to be excellent substrates of kinases for the phosphorylations. 2′,3′-Dideoxy-2,-a-fluoro-2′-{3-C-methyl-nucleosides can be considered as one unique class of 2′,3′-dideoxynucleosides to be good substrate of kinases because fluorine mimics hydrogen. It also can be considered as ribo-nucleosides to incorporate into RNA of HCV because 2′-fluorine-a mimics 2′-a-OH group. |
