Abstract A series of acyclic C-nucleoside analogs of 2,6-dichloro- and 2,6,7-trichloroimidazo[1,2-a]pyridine were synthesized and tested for antiviral activity. The appropriate hydroxymethyl-substituted heterocycles were treated successively with thionyl chloride, an appropriate nucleophile, then diisopropylethylamine to obtain the desired acyclic nucleoside analogs. These compounds were evaluated
摘要 合成了一系列2,6-二氯-和2,6,7-三氯咪唑并[1,2-a]吡啶的无环C-核苷类似物并测试了其抗病毒活性。合适的羟甲基取代的杂环依次用亚硫酰氯、合适的亲核试剂、然后二异丙基乙胺处理以获得所需的无环核苷类似物。评估了这些化合物对人类巨细胞病毒和 1 型单纯疱疹病毒的活性。两种二氯类似物,但没有一种三氯类似物在非细胞毒性浓度下表现出轻微的抗病毒活性(IC50 = 20–45 µM)。
