binofuranosylpyrimidine nucleosides as anti-HBV agents. Therefore it is rational to extend this study to the purine nucleosides. Thus, 3,5-di-O-benzoyl-2-deoxy-2-fluoro-beta-L-arabinofuranosyl bromide (1), which was prepared from L-xylose via a multistep procedure, was coupled with several purines by the sodium salt method. From this general synthesis, 10 purine nucleosides containing the 2-deoxy-
自从发现2'-氟-5-甲基-β-L-阿拉伯呋喃糖基尿嘧啶(L-FMAU)作为有效的抗HBV和抗EBV剂以来,我们研究了2'-deoxy-2的构效关系'-氟-β-L-阿拉伯呋喃糖基嘧啶核苷作为抗HBV药物。因此,将这项研究扩展到嘌呤核苷是合理的。因此,将由L-木糖经多步程序制得的3,5-二-O-苯甲酰基-2-脱氧-2-氟-β-L-阿拉伯呋喃糖基溴化物(1)与钠的几个嘌呤偶联。盐法。通过该一般合成,获得了含有2-脱氧-2-氟-β-L-阿拉伯呋喃糖基部分的10个嘌呤核苷。在HepG2 2.2.15细胞中评估了合成核苷的抗HBV活性和毒性。他们之中,
