The present invention relates to 3′-azido purine nucleosides of formula (I) and their use in medical therapy, particularly for the treatment or prophylaxis of human immunodeficiency virus and hepatitis B virus infections, to methods for their preparation and to compositions containing them.
wherein R represents halogen; C₁₋₆ alkoxy; C₃₋₆ cycloalkoxy; aryloxy or arylalkoxy in which the aryl may optionally be substituted with C₁₋₆ alkyl, C₁₋₆ alkoxy, halogen, nitro or hydroxyl; amino which is substituted by one or two substituents indepently selected from C₁₋₆ alkyl, aryl, aralkyl including aracycloalkyl and C₃₋₆ cycloalkyl; or a 4- to 6- membered heterocyclic ring containing at least one nitrogen atom which ring is bonded to the purine base via a/the nitrogen atom; or a pharmaceutically acceptable derivative thereof.
本发明涉及式(I)的3′-叠氮嘌呤核苷及其在医学治疗中的用途,特别是用于治疗或预防人类免疫缺陷病毒和乙型肝炎病毒感染,还涉及其制备方法和含有它们的组合物。
其中 R 代表卤素;C₁₋₆ 烷氧基;C₃₋₆ 环烷氧基;芳氧基或芳烷氧基,其中芳基可任选被 C₁₋₆ 烷基、C₁₋₆ 烷氧基、卤素、硝基或羟基取代;被一个或两个取代基取代的氨基,这些取代基独立地选自 C₁₋₆烷基、芳基、芳烷基(包括芳环烷基)和 C₃₋₆环烷基;或含有至少一个氮原子的 4-6 位杂环,该杂环通过一个氮原子与嘌呤基结合;或其药学上可接受的衍生物。
