The invention relates to a new synthesis process of cytosine nucleoside analogues by using nucleoside phosphorylase enzymes, particularly Pyrimidin Nucleoside Phosphorylases (PyNPs) or mixtures of Purine Nucleoside Phosphorylases (PNPs) and PyNPs.
The disclosed invention provides compositions and methods of treating a Flaviviridae infection, including hepatitis C virus, West Nile Virus, yellow fever virus, and a rhinovirus infection in a host, including animals, and especially humans, using a (2′R)-2′-deoxy-2′-fluoro-2′-C-methyl nucleosides, or a pharmaceutically acceptable salt or prodrug thereof.
