This invention is directed to a method for treating a host infected with hepatitis B comprising administering an effective amount of an anti-HBV biologically active 2′-deoxy-&bgr;-L-erythro-pentofuranonucleoside or a pharmaceutically acceptable salt or prodrug thereof, wherein the 2′-deoxy-&bgr;-L-erythro-pentofuranonucleoside has the formula:
1
wherein R is selected from the group consisting of H, straight chained, branched or cyclic alkyl, CO-alkyl, CO-aryl, CO-alkoxyalkyl, CO-aryloxyalkyl, CO-substituted aryl, alkylsulfonyl, arylsulfonyl, aralkylsulfonyl, amino acid residue, mono, di, or triphosphate, or a phosphate derivative; and BASE is a purine or pyrimidine base which may be optionally substituted. The 2′-deoxy-&bgr;-L-erythro-pentofuranonucleoside or a pharmaceutically acceptable salt or prodrug thereof may be administered either alone or in combination with another 2′-deoxy-&bgr;-L-erythro-pentofuranonucleoside or in combination with another anti-hepatitis B agent.
本发明涉及一种治疗乙型肝炎感染宿主的方法,包括给予一种抗HBV生物活性2'-脱氧-β-L-核糖呋喃核苷或其药学上可接受的盐或前药的有效量,其中2'-脱氧-β-L-核糖呋喃核苷的化学式为:1,其中R选自H、直链、支链或环烷基、CO-烷基、CO-芳基、CO-烷氧基烷基、CO-芳氧基烷基、CO-取代芳基、烷基磺酰基、芳基磺酰基、芳基烷基磺酰基、氨基酸残基、单、二或三磷酸盐或磷酸衍生物;BASE是嘌呤或嘧啶碱基,可以选择性地被取代。2'-脱氧-β-L-核糖呋喃核苷或其药学上可接受的盐或前药可以单独使用或与另一种2'-脱氧-β-L-核糖呋喃核苷或另一种抗乙型肝炎药物联合使用。
