Abstract

A novel β-D-2'-deoxy-2'-α-fluoro-2'-β-C-(fluoromethyl)uridine phosphoramidate prodrug (1) has been synthesized. This compound exhibits submicromolar-level Antiviral activity in vitro against HCV genotypes 1b, 1a, 2a, and S282T replicons (EC50 = 0.18-1.13 μM) with low cytotoxicity (CC50 > 1000 μM). Administered orally, prodrug 1 is well tolerated at doses of up to 4 g/kg in mice, and produces a high level of the corresponding triphosphate in rat liver.
