A series of pyrano[2,3-c]pyrazol-4-ones was synthesized and evaluated for bovine brain adenosine A1 and A2A receptor binding affinity. Substituents at positions 5 and/or 6 were varied in order to define the structure-activity relationships in these new kinds of adenosine receptor ligands. The most selective and potent ligand among the reported compounds was the 1,4-dihydro-1-phenyl-3-methyl-6-(3-a
合成了一系列吡喃并[2,3-c]吡唑-4-酮并评估了牛脑腺苷A1和A2A受体的结合亲和力。改变位置5和/或6的取代基,以便定义这些新型腺苷受体配体中的构效关系。在所报道的化合物中,最有选择性和最有效的配体是1,4-二氢-1-苯基-3-甲基-6-(3-氨基苯基)-吡喃并[2,3-c]吡唑ol-4-one 11对A1受体的选择性显示27倍,Ki值为84 nM。
