In order to study the structure-activity relationships of 2',3'-dideoxypurine nucleosides as potential anti-HIV agents, various 6-substituted purine analogues have been synthesized and examined in virus-infected and uninfected human peripheral blood mononuclear cells. N6-methyl-2',3'-dideoxyadenosine (D2MeA, 7a) was initially synthesized from adenosine via 2',3'-O-bisxanthate 3. As extension of this
为了研究2',3'-二脱氧嘌呤核苷作为潜在的抗HIV药物的构效关系,已经合成了多种6-取代的嘌呤类似物,并在病毒感染和未感染的人外周血单核细胞中进行了研究。N6-甲基-2',3'-二脱氧腺苷(D2MeA,7a)最初是通过2',3'-O-双黄药3由腺苷合成的。由于该反应扩展到其他N6-取代的化合物失败,因此采用了全合成方法利用2',3'-二脱氧核糖衍生物9合成其他嘌呤核苷。通过与N6-甲基腺嘌呤23缩合,由合适的碳水化合物24合成了N6-甲基-2',3'-二脱氧腺苷,2'-氟阿拉伯呋喃糖基类似物32(D2MeFA)的酸稳定衍生物。N6-甲基衍生物(D2MeA)7a被证明是最有效的抗病毒药物之一。对于6个取代的化合物,其效力顺序为NHMe大于NH2大于Cl约N(Me)2大于SMe大于OH约NHEt大于SH大于NHBn约H。 2',3'-二脱氧嘌呤核苷的6位可能决定这些化合物的抗病毒活性。发现酸
