(-)-5'-noraristeromycin (1) has shown antiviral activity towards, particularly cytomegalovirus, vaccinia virus and measles while its (+)-enantiomer (2) is effective towards hepatitis B virus. To determine if the antiviral characteristics of 1 and 2 extended to the guanine analogues (3 and 4), these enantiomers were prepared and evaluated against herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2)
(-)-5'-诺拉霉素(1)已显示出对尤其是巨细胞病毒,牛痘病毒和麻疹的抗病毒活性,而其(+)-对映体(2)对乙型肝炎病毒有效。为了确定1和2的抗病毒特性是否扩展到鸟嘌呤类似物(3和4),制备了这些对映异构体并针对1型单纯疱疹病毒(HSV-1)和2型单纯疱疹病毒(HSV-2),巨细胞病毒(CMV)进行了评估。 ),水痘带状疱疹病毒(VZV),爱泼斯坦-巴尔病毒(EBV),人类疱疹病毒6型(HHV-6),人类疱疹病毒8型(HHV-8),牛痘病毒(VV),牛痘病毒(CV) ,水泡性口炎病毒(VSV),呼吸道合胞病毒(RSV),乙型肝炎病毒(HBV)和1型人类免疫缺陷病毒(HIV-1)和2型人类免疫缺陷病毒(HIV-2)。发现3的唯一活性是针对VCA Elisa中的爱泼斯坦-巴尔病毒(EC50 0.78 microg / mL),用于VCA或gp 350/250(1.8-4.0 microg /
