AICAR-related compounds modified at the 2′- or 5′-position of the ribose moiety are reported herein. In particular, 5′-azido, 5′-amino, 5′-O-benzyl and a series of 2′-O-alkylated AICAR derivatives have been synthesized. These compounds were derived from appropriately functionalized inosines by opening the pyrimidine ring at the hypoxanthine residue. The target derivatives were designed with the purpose of
本文报道了在核糖部分的 2'-或 5'-位修饰的 AICAR 相关化合物的一些选择性制备。特别是,已经合成了 5'-叠氮基、5'-氨基、5'-O-苄基和一系列 2'-O-烷基化的 AICAR 衍生物。这些化合物通过在次黄嘌呤残基处打开嘧啶环而衍生自适当官能化的肌苷。设计目标衍生物的目的是研究 AICAR 结构修饰对其抑制 Hsp90 能力的影响,Hsp90 是开发抗癌药物的生物靶标之一。尽管如此,开发类似 AICAR 的化合物也是一个吸引人的目标,因为它们在代谢研究领域具有潜在的治疗应用。(© Wiley-VCH Verlag GmbH & Co.
