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.
检测了(-)-顺式-5-氟-1-[2-(羟甲基)-1,3-氧硫杂环戊烷-5-基]胞嘧啶(524W91)在原代人肝细胞培养物中的抗乙型肝炎病毒(HBV)活性。524W91在这些细胞中被代谢为活性5'-三磷酸。当在感染前24小时、感染时或感染后24小时添加该药物时,524W91在培养物中对HBV复制的抑制作用相同。在人肝细胞中,524W91在低于20 nM时对HBV复制的抑制率达50%。
