1‐(2‐methoxyphenyl)‐4‐[(1‐phenethylpiperidin‐4‐yl)methyl]piperazines were synthesized to be used as probes for mapping the dopamine D2 receptor (D2DAR) arylpiperazine binding site. All compounds were evaluated for their affinity toward D2DAR in an in vitro competitive displacement assay. The most active one was 1‐(2‐methoxyphenyl)‐4‐[1‐(3‐nitrophenethyl)piperidin‐4‐yl]methyl}piperazine (25) with an affinity of
合成了 16 种新的 1-(2-甲氧基苯基)-4-(1-苯乙基哌啶-4-基)哌嗪和 1-(2-甲氧基苯基)-4-[(1-苯乙基哌啶-4-基)甲基]哌嗪。用作绘制多巴胺 D2 受体 (D2DAR) 芳基哌嗪结合位点的探针。在体外竞争性置换试验中评估了所有化合物对 D2DAR 的亲和力。最活跃的是 1-(2-甲氧基苯基)-4-[1-(3-硝基苯乙基)哌啶-4-基]甲基}哌嗪 (25),其亲和力为 Ki = 54 nM。对本文所述的所有化合物进行对接分析,而对配体25进行分子动力学模拟以建立其与D2DAR的相互作用模式。提出了两种可能的对接方向;D2DAR 的哌啶部分和 Asp114 之间具有盐桥的更稳定。
