A series of 2-amino-4,5,6,7-tetrahydrothieno[2,3-c]pyridines were prepared and evaluated as potential allosteric modulators at the A1 adenosine receptor. The structure–activity relationships of the 3- and 6-positions of a series of 2-amino-4,5,6,7-tetrahydrothieno[2,3-c]pyridines were explored. Despite finding that 3- and 6-substituted 2-amino-4,5,6,7-tetrahydrothieno[2,3-c]pyridines possess the ability
制备了一系列 2-氨基-4,5,6,7-四氢噻吩并 [2,3- c ] 吡啶,并将其评估为 A 1腺苷受体的潜在变构调节剂。探索了一系列2-氨基-4,5,6,7-四氢噻吩并[2,3- c ]吡啶的3-和6-位的构效关系。尽管发现3-和6-取代的2-氨基-4,5,6,7-四氢噻吩并[2,3- c ]吡啶具有识别激动剂占据的A 1上的变构位点的能力AR 在相对高的浓度下,我们在这个支架上进行的结构修改有利于表达正构拮抗剂特性而不是变构特性。该研究已将 2-amino-4,5,6,7-四氢噻吩并 [2,3- c ] 吡啶鉴定为 A 1 AR 的新型正构拮抗剂,并强调了控制变构调节和正构拮抗的结构元件之间的密切关系在 A 1 AR的激动剂功能。
