inactive, nucleosides bearing cycloalkyl substituents on N6 exhibited moderate to good anti-HIV-1 activity, compared to 2',3'-dideoxyadenosine, with the degree and pattern of improvement depending on the structure of the sugar moiety. In general, 2'-deoxy- and 2',3'-dideoxy derivatives were more potent compounds than the corresponding ribose nucleosides. Compounds bearing a 6-cycloheptyl or cyclooctylamine
一系列带有N6氮的未取代或带有甲基或环烷基取代基的1-deazaadenine核苷,其2位上有或没有氯基,且糖基部分为核糖(1-16),2'-脱氧核糖(17从5,7-二氯-3H-咪唑并[4,5-b]吡啶(50)开始设计和合成-32)或2',3'-二脱氧核糖(33-48)。评估了这些化合物的抗人免疫缺陷病毒1型(HIV-1)和单纯疱疹病毒1型(HSV-1)的体外活性。此外,还测试了它们抑制小牛肠腺苷脱氨酶(ADA)的能力。尽管母体化合物1-deazaadenosine(9),2'-deoxy-1-deazaadenosine(25)和2',3'-dideoxy-1-deazaadenosine(41)和相应的2-chloro衍生物均无活性,与2',3'-二脱氧腺苷相比,在N6上带有环烷基取代基的核苷具有中等至良好的抗HIV-1活性,其改善的程度和方式取决于糖部分的结构。通常,2'-脱氧-和2
