the cytopathic effects of HIV in both host cell lines. 2'-Fluoro substitution confers increased chemical and enzymatic stability on dideoxynucleosides. Even though dideoxy pyrimidine nucleosides are inherently more stable than the corresponding purine analogues toward acid-catalyzed cleavage of the glycosidic bond, 2'-fluoro substitution (10a) still increases stabilization relative to ddC (2b). No detectable
为了寻找有用的抗爱滋病药物,已经研究了一系列1-(2,3-二脱氧-2-氟-β-D-thopenopentofuranosyl)pyrimidines的合成,化学,生物化学和抗HIV活性。通过2,3-二脱氧核糖中间体进行合成,该中间体通过在与尿嘧啶或胞嘧啶糖苷配子缩合之前而不是之后除去糖的3'-羟基来促进类似物的制备。2'-F-dd-尿苷类似物7a-d(在5位上具有H,F,Cl和CH3取代)以及4-脱氧化合物(12b)对感染了ATH8或CEM的细胞无保护作用HIV-1。在相应的胞苷系列中,5-氯类似物(11)没有活性。然而,2′-氟-2′,3′-二脱氧阿拉伯糖基胞嘧啶10a和其5-氟类似物10b都具有活性。虽然这两种化合物都不具有像ddC或5-F-ddC那样的强效作用(2b),但10b可以完全抵抗两种宿主细胞系中HIV的细胞病变作用。2'-氟取代赋予双脱氧核苷化学和酶稳定性。尽管双脱氧嘧啶核
