Penciclovir [9-(4-hydroxy-3-hydroxymethylbut-1-yI)guanine], an effective antiherpesvirus agent, was found to be a potent and selective antiviral agent against intracellular hepatitis B virus (HBV) replication (drug concentration at which a 10-fold decrease in HBV DNA from the average level in an untreated culture was observed [EC90], 1.6 microM) and extracellular virion release (EC90, 0.7 microM) by cultured human hepatoblastoma (2.2.15) cells. Acyclovir and three other related 9-alkoxypurines with activity against either herpesviruses or human immunodeficiency virus were uniformly inactive against HBV. The activity of penciclovir is discussed in relation to recent findings related to its mode of action against HBV.
喷昔洛韦[9-(4-羟基-3-羟甲基丁-1-基)鸟嘌呤]是一种有效的抗疱疹病毒药物,已被发现是一种针对细胞内乙型肝炎病毒(HBV)复制的强效且具有选择性的抗病毒药物(观察到将未处理培养物中的HBV DNA平均水平降低10倍时的药物浓度[EC90]为1.6微摩尔),并且对培养的人肝母细胞瘤(2.2.15)细胞的细胞外病毒粒子释放也有抑制作用(EC90为0.7微摩尔)。阿昔洛韦以及其他三种对疱疹病毒或人类免疫缺陷病毒有活性的相关9-烷氧基嘌呤对HBV均无活性。结合最近关于喷昔洛韦抗HBV作用模式的研究结果对其活性进行了讨论。
