以(间氯)苯甲酰基保护的2'-脱氧-2'-β-氟-4'-叠氮尿苷为起始原料,经过硝酸铈铵(CAN)介导的卤代、三氮唑活化、胺化、脱保护合成了一系列5-卤代的2'-脱氧-2'-β-氟-4'-叠氮嘧啶核苷类化合物.体外生物活性评价研究表明,5-氯代(6a)和5-碘代(6c)核苷衍生物具有很好的抗乙肝病毒活性,而且细胞毒性较小.

关键词: 5-卤代, 嘧啶核苷, 合成, 抗乙肝病毒活性

A series of 5-halogenated 2'-deoxy-2'-β-fluoro-4'-azido pyrimidine nucleosides were synthesized from m-chloro-benzoyl protected 2'-deoxy-2'-β-fluoro-4'-azido uridine via ammonium cerium nitrate (CAN)-mediated halogenation, activation by triazole, amination, and deprotection. In vitro biological evaluation demonstrated that 5-chloro (6a) and 5-iodo (6c) nucleoside derivatives possess potent anti-HBV (hepatitis B virus) activity with low cytotoxicity.

Key words: 5-halogenated, pyrimidine nucleoside, synthesis, anti-HBV activity
