We studied the structure-activity relationships of a series of 2'-fluoro-2',3'-unsaturated D-nucleosides against HIV-1 in human peripheral blood mononuclear (PBM) cells. The target compounds 10-21 and 28-33 were prepared by N-glycosylation of the acetate 4, which was readily prepared from 2,3-O-isopropylidene-D-glyceraldehyde in five steps. Among the newly synthesized nucleosides, 2-amino-6-chloropurine
我们研究了人类外周血单核(PBM)细胞中一系列针对HIV-1的2'-氟-2',3'-不饱和D-核苷的构效关系。通过乙酸酯4的N-糖基化制备目标化合物10-21和28-33,乙酸酯4容易地由2,3-O-异亚丙基-D-甘油醛分五个步骤制备。在新合成的核苷中,有2-氨基-6-氯嘌呤(11),腺嘌呤(14),肌苷(16),鸟嘌呤(18),2,6-二氨基嘌呤(20)和5-氟胞嘧啶(30)衍生物。发现具有EC(50)值分别为4.3、0.44、1.0、2.6、3.0和0.82 microM的有趣的抗HIV活性。还检查了有关拉米夫定耐药变体(M184V)对标题核苷的耐药性的影响,
