A new series of anhydrohexitol nucleosides are described. These compounds have a pyrimidine base moiety substituted in the 5-position with a chloro (1b), trifluoromethyl (1c), vinyl (1d), 2-thienyl (1e), ethynyl (1f) or propynyl (1g) substituent. The vinyl, propynyl, and, in particular, the 5-trifluoromethyl analogue showed potent activity against herpes simplex virus (HSV), 1c with a selectivity index
描述了一系列新的脱水己糖醇核苷。这些化合物具有在5位上被氯(1b),三氟甲基(1c),乙烯基(1d),2-噻吩基(1e),乙炔基(1f)或丙炔基(1g)取代基取代的嘧啶碱基部分。乙烯基,丙炔基,尤其是5-三氟甲基类似物显示出对单纯疱疹病毒(HSV)的有效活性,其1c对HSV-1的选择性指数> 16000,对HSV-2的选择性指数> 1000。使用计算方法对脱水己糖醇核苷进行构象分析表明,这些核苷在C1和1C形式之间平衡存在,其DeltaE为5.9 kJ / mol。当脱水己糖醇核苷与HSV-1胸苷激酶共结晶时,它采用1C构象,这与仅在小分子中发现的构象相反。酵素
