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-β-L-erythro-pentofuranonucleoside or a pharmaceutically acceptable salt or prodrug thereof, wherein the 2′-deoxy-β-L-erythro-pentofuranonucleoside has the formula:
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-β-L-erythro-pentofuranonucleoside or a pharmaceutically acceptable salt or prodrug thereof may be administered either alone or in combination with another 2′-deoxy-β-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,包括给予有效量的抗乙肝病毒生物活性2'-脱氧-β-L-赤霉糖核苷或其药学上可接受的盐或前药,其中2'-脱氧-β-L-赤霉糖核苷的化学式为: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是一种嘌呤或嘧啶碱基,可以选择性地被取代。2'-脱氧-β-L-赤霉糖核苷或其药学上可接受的盐或前药可以单独或与另一种2'-脱氧-β-L-赤霉糖核苷或其他抗乙肝药物联合使用。
