Human Cytomegalovirus (HCMV) replication by benzimidazole nucleosides, like Triciribine and Maribavir, has prompted us to expand the structure–activity relationships of the benzimidazole series, using as a central core the imidazo[4,5-b]pyridine scaffold. We have thus synthesized a number of novel amino substituted imidazopyridine nucleoside derivatives, which can be considered as 4-(or 7)-aza-d-isosters
苯并咪唑核苷(如曲西立宾和马里巴韦)对人巨细胞病毒 (HCMV) 复制的强烈抑制促使我们扩展苯并咪唑系列的构效关系,以咪唑并 [4,5-b] 吡啶支架作为中心核心. 因此,我们合成了许多新型氨基取代的咪唑并吡啶核苷衍生物,它们可以被认为是 Maribavir 的 4-(或 7)-氮杂-d-异构体,并评估了它们的潜在抗病毒活性。目标化合物是在适当取代的 2-氨基咪唑并吡啶糖基化后合成的,该化合物从 2-氨基-6-氯吡啶开始,分六步制备。即使与原始药物相比,新化合物仅具有轻微的结构修饰,它们也没有被赋予有趣的抗病毒活性。尽管如此,
