Uses
1-β-D-Arabinofuranosyluracil-2-C-methyl-d3, 13C is the labeled analogue of 1-β-D-Arabinofuranosyluracil-2-C-methyl (A764005), an impurity of PSI-7977 (P839640), a prodrug that is metabolized to the active antiviral agent 2''-deoxy-2''-α-fluoro-β-C-methyluridine-5''-monophosphate and is currently being investigated in phase 3 clinical trials for the treatment of hepatitis C. Studies have profiled PSI-7977 as a nucleotide inhibitor of hepatitis C virus, exerting selective inhibitory effects towards HCV NS5B polymerase.
