2,4]triazolo[1,5-a]pyridine-6-carboxyl amide derivatives is described for the first time. A subset of 20 derivatives were compared to their isomeric 5-amino-2-aryl-[1,2,4]triazolo[1,5-a]pyridine-7-carboxyl amide counterparts with regard to their potential to inhibit the human adenosine 2a (hA2a) receptor and their selectivity against the human adenosine 1 (hA1) receptor. Based on the analysis of H-bond
首次描述了一系列8-氨基-2-芳基-[1,2,4]三唑并[1,5-a]吡啶-6-羧基酰胺衍生物的合成。将20种衍生物的一部分与它们的同分异构的5-氨基-2-芳基-[1,2,4]三唑并[1,5-a]吡啶-7-羧基酰胺对应物相比,它们具有抑制人腺苷的潜力2a(hA2a)受体及其对人腺苷1(hA1)受体的选择性。基于对异构三唑并吡啶对的H键供体/受体能力的分析,可以得出结论,游离氨基官能团的H键供体强度是hA2a抑制活性和hA1选择性的主要决定因素。
