A series of sugar-modified derivatives of oxanosine and its carbocyclic analogs were synthesized from natural oxanosine and (−)-2-azabicyclo[2.2.1]hept-5-en-3-one, respectively. Among nucleosides tested for anti-HIV activities in vitro, oxanosine 1, its 5′-monophosphate 9, and 2′-deoxyoxanosine 8 reduced the number of HIV particles in CEM cells to almost the same level as ddI.
研究人员分别从天然草苷和(-)-2-氮杂双环[2.2.1]庚-5-烯-3-酮合成了一系列草苷及其碳环类似物的糖修饰衍生物。在体外抗艾滋病毒活性测试的核苷中,草苷 1、其 5′-单磷酸 9 和 2′-脱氧草苷 8 可将 CEM 细胞中的艾滋病毒颗粒数量减少到与 ddI 几乎相同的水平。
