tetrahydropyrazino[2,1-f]purinediones was obtained and evaluated for their adenosine receptors (ARs) affinities. The 1,3-dibutyl derivative of 9-(4-(2-(dimethylamino)ethoxy)phenyl)-6,7,8,9-tetrahydropyrimido[1,2-f]purine-2,4(1H,3H)-dione was found to be the most potent A1 AR antagonist of the present series, showing selectivity over the other AR subtypes. The structure-activity for the obtained purinediones
获得了一系列新的32个嘧啶基和5个四氢吡嗪并[2,1-f]嘌呤二酮,并对其腺苷受体(ARs)亲和力进行了评估。9-(4-(2-(二甲基氨基)乙氧基)苯基)-1,3-二丁基衍生物-6,7,8,9-四氢嘧啶基[1,2-f]嘌呤-2,4(1H,3H) -dione被发现是本系列中最有效的A1 AR拮抗剂,显示出对其他AR亚型的选择性。建立了获得的嘌呤二酮的结构活性。将研究的文库与人和大鼠A1和A2A AR的同源性模型对接实验,可以比较所选化合物的预期结合模式。
