The synthesis of two series of 4′-aza-carbocyclic nucleosides are described in which the 4′-substituent is either a reversed amide, relative to the carboxamide of NECA, or an N-bonded heterocycle. Using established purine substitution patterns, potent and selective examples of agonists of the human adenosine A2A receptor have been identified from both series. The propionamides 14–18 and the 4-hydroxymethylpyrazole
描述了两个系列的4'-氮杂-碳环核苷的合成,其中4'-取代基是相对于NECA的羧酰胺而言是反向酰胺,或者是N键合的杂环。使用已建立的嘌呤取代模式,已从两个系列中鉴定出人腺苷A 2A受体激动剂的有效和选择性实例。丙酰胺类14 - 18和4-羟基甲基吡唑32被确定为从4'-反转酰胺的最有效的和选择性的实施例和4'- Ñ分别键合的杂环系列。
