Investigation of various N-heterocyclic substituted piperazine versions of 5/7-{[2-(4-aryl-piperazin-1-yl)-ethyl]-propyl-amino}-5,6,7,8-tetrahydro-naphthalen-2-ol: Effect on affinity and selectivity for dopamine D3 receptor

displaying higher affinity at both D2 and D3 receptors compared to its enantiomer (+)-10e (Ki; D2 = 113 nM, D3 = 3.73 nM). Additionally, compound (−)-10e was more potent and selective for the D3 receptor compared to either 7-OH-DPAT or 5-OH-DPAT. Among the bioisosteric derivatives, the indazole derivative 10g and benzo[b]thiophene derivative 10i exhibited the highest affinity for D2 and D3 receptors. In the
在这里,我们报告了属于 5/7-[2-(4-aryl-piperazin-1-yl)-ethyl]-propyl-amino}-5,6,7,8 的几种杂环类似物的设计和合成-tetrahydro-naphthalen-2-ol 系列分子。对化合物进行 [ 3 H] 螺环哌啶酮结合测定,用表达 D2 或 D3 多巴胺受体的 HEK-293 细胞进行,以评估它们的抑制常数 ( K i) 在这些受体上。结果表明哌嗪环上的 N-取代可以容纳各种取代的吲哚环。结果还表明,为了保持对 D3 受体的高亲和力和选择性,杂环不需要直接连接到哌嗪环上,因为此处包括的大多数化合物通过酰胺或亚甲基接头连接到杂环部分。最有效的外消旋化合物10e的对映异构体与 (-)- 10e ( K i ; D2 = 47.5 nM, D3 = 0.57 nM)表现出不同的活性,与其对映异构体 (+)- 10e相比,对 D2 和
