evaluated against a range of viral strains. The thymidine analogue showed pronounced activity against herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2), varicella-zoster virus (VZV), and vaccinia virus. This compound lost only 5- to 10-fold of its antiviral activity against thymidine kinase (TK)-deficient HSV-1 and VZV strains. These observations suggest that the compounds may not entirely depend
描述了一系列新颖的1-(2-脱氧-4-硫代-β-D-赤型-呋喃呋喃糖基)-(6-氮杂嘧啶)核苷的合成。胸腺嘧啶核苷衍生物的X射线晶体学数据允许进行构象分析,表明存在扭曲(3T2)糖构象。使用PLATON软件确定用于晶体结构的氢键组装体,以进一步解释晶体堆积和碱基相互作用。针对一系列病毒株评估了所述的6-氮杂嘧啶核苷。胸苷类似物对1型单纯疱疹病毒(HSV-1)和2型单纯疱疹病毒(HSV-2),水痘带状疱疹病毒(VZV)和牛痘病毒具有明显的活性。该化合物对缺乏胸苷激酶(TK)的HSV-1和VZV菌株的抗病毒活性仅丧失了5至10倍。
