A number of 4-aminopyrazolo[3,4-b]pyridines 5-carboxylic acid esters (2-8) were synthesized and evaluated for their binding affinity at the A1, A2A, and A3 adenosine receptors (AR), in bovine cortical membranes, as well as for their affinity toward human A1AR (hA1AR). Some of the new compounds were characterized by a high affinity and selectivity toward the A1 receptor subtype, showing a significant
合成了许多4-氨基吡唑并[3,4-b]吡啶5-羧酸酯(2-8),并对其在牛皮膜中对A1,A2A和A3腺苷受体(AR)的结合亲和力进行了评估。 ,以及它们对人类A1AR(hA1AR)的亲和力。一些新化合物的特征是对A1受体亚型具有高亲和力和选择性,与先前文献中报道的其他吡唑并吡啶相比,显示出显着改善。特别地,它们都在4位带有对甲氧基苯基乙基氨基侧链的甲酯2h以及异丙酯5h分别具有6nM和7nM的Ki值。为使新型化合物的结构与亲和力之间的关系合理化,
