The present invention relates to the surprising discovery that certain dideoxynucleoside analogs which contain a dideoxy ribofuranosyl moiety having an L-configuration (as opposed to the naturally occurring D- configuration) exhibit unexpected activity against Hepatitis B virus (HBV). In particular, the compounds according to the present invention show potent inhibition of the replication of the virus in combination with very low toxicity to the host cells (i.e., animal or human tissue). Compounds according to the present invention exhibit primary utility as agents for inhibiting the growth or replication of HBV, HIV and other retroviruses, most preferably HBV.
本发明涉及一种惊人的发现,即某些含有L-构型(与天然存在的D-构型相反)的二脱氧核苷类似物,其含有二脱氧
核糖苷基团,对乙型肝炎病毒(HBV)具有意想不到的活性。特别是,本发明的化合物在与宿主细胞(即动物或人类组织)的毒性非常低的情况下,表现出对病毒复制的强效抑制作用。本发明的化合物主要用作抑制HBV、HIV和其他逆转录病毒的生长或复制的药剂,其中最好是用于HBV的治疗。
