title: (-)-cis-5-fluoro-1-[2-(hydroxymethyl)-1,3-oxathiolan-5-yl]cytosine (524W91) inhibits hepatitis B virus replication in primary human hepatocytes.
abstract: The anti-hepatitis B virus (HBV) activity of (-)-cis-5-fluoro-1-[2-(hydroxymethyl)-1,3-oxathiolan-5-yl]cytosine (524W91) in cultures of primary human hepatocytes was examined. 524W91 was anabolized to the active 5'-triphosphate in these cells. HBV replication was equally inhibited in cultures incubated with 524W91 when the drug was added 24 h preinfection, at infection, or 24 h postinfection. 524W91 inhibited HBV replication by 50% at less than 20 nM in human hepatocytes.
