  • Publication number: 20190077797
    Abstract: Methods for forming 2-bromo, 2-fluoro ribofuranose intermediates and 2-chloro, 2-fluoro ribofuranose intermediates for use in preparing antiviral nucleosides are disclosed. Methods for forming nucleosides, and nucleoside prodrugs, using the intermediates, are also disclosed. The methods all produce intermediates, and the resulting nucleosides and prodrugs thereof, wherein the chirality of the carbon at the 2-position is controlled. In some embodiments, the chemistry involves using chiral auxiliaries, such as (R)-2,2-dimethyl-1,3-dioxolane-4-carbaldehyde, and in other embodiments, the chemistry involves using chiral starting materials, such as D-xylose.

  • Publication number: 20140212382
    Abstract: 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.
