The synthesis, in vitro anti-HIV-1 activity, and decomposition pathways of several mononucleoside phosphotriester derivatives of 3'-azido-2',3'-dideoxythymidine (AZT) incorporating a new kind of carboxylate esterase-labile transient phosphate-protecting group, namely, S-acyl-2-thioethyl, are reported. All the described compounds showed marked antiviral activity in thymidine kinase-deficient CEM cells
3'-叠氮基2',3'-二脱氧胸苷(AZT)的几种单核苷磷酸三酯衍生物的合成,体外抗HIV-1活性和分解途径,结合了一种新型的羧酸酯酶不稳定的瞬时磷酸保护基团据报道,即S-酰基-2-硫代乙基。所有描述的化合物在胸腺嘧啶激酶缺失的CEM细胞中均表现出显着的抗病毒活性,其中AZT实际上是无活性的。结果强烈支持这样的假说,即这种前核苷酸通过AZT的5'-单核苷酸的细胞内递送发挥其生物学作用。在细胞提取物和培养基中的分解研究证实了这一点。
