Three nucleoside analogues, 3′-fluoro-2′,3′-dideoxythymidine (FLT), 3′-azido-2′,3′-dideoxythymidine (AZT), and 2′,3′-dideoxy-3′-thiacytidine (3TC) were conjugated with three different dicarboxylic acids to afford the long chain dicarboxylate esters of nucleosides. In general, dinucleoside ester conjugates of FLT and 3TC with long chain dicarboxylic acids exhibited higher anti-HIV activity than their parent
三种核苷类似物3'-氟-2',3'-二脱氧胸苷(FLT),3'-叠氮基2',3'-二脱氧胸苷(AZT)和2',3'-二脱氧胸苷3'-硫代胞苷(将3TC)与三种不同的二羧酸缀合以提供核苷的长链二羧酸酯。通常,FLT和3TC与长链二元羧酸的二核苷酯共轭物显示出比其母体核苷更高的抗HIV活性。发现FLT的十二烷酸酯和十四烷酸酯二核苷酯衍生物是针对HIV-1 US / 92/727和HIV-1 IIIB细胞的EC 50值分别为0.8-1.0 nM和3-4 nM的最有效化合物。含有长链二羧酸二酯的3TC偶联物的抗HIV活性(EC 50 = 3-60 nM)与3TC(EC 50 = 90-200 nM)相比提高了1.5-66倍。这项研究表明,二羧酸与许多核苷的对称酯缀合可产生具有改进的抗HIV谱的缀合物。
