play a key role in the treatment of such disorders. In this context, a novel series of conformationally restricted N-arylpiperazine derivatives (5a–f) with a good affinity for D2/D3 dopamine receptors is reported herein. Compounds were designed as interphenylene analogs of the drugs aripiprazole (2) and cariprazine (3), presenting a 1,3-benzodioxolyl subunit as a ligand of the secondary binding site of
大多数神经退行性疾病是多因素的,与其发病机制相关的几种分子机制的发现不断推进。多巴胺和多巴胺能受体亚型涉及几种神经系统疾病的病理生理学,例如精神分裂症、抑郁症和药物成瘾。因此,多巴胺能系统和多巴胺受体配体在此类疾病的治疗中起关键作用。在这种情况下,一系列对 D 2 /D 3具有良好亲和力的新型构象受限的N-芳基哌嗪衍生物 ( 5a – f )本文报道了多巴胺受体。化合物被设计为药物阿立哌唑 (2) 和卡利拉嗪 (3) 的苯间苯类似物,呈现 1,3-苯并二氧戊环亚基作为这些受体二级结合位点的配体。使用经典方法以良好的收率合成了六种新的N-芳基哌嗪化合物,并进行了结合和鸟苷三磷酸 (GTP) 位移研究。发现靶受体的亲和力值低于 1 μM 和不同的内在功效谱。对接研究表明,化合物5a – f与多巴胺 D 2和 D 3呈现不同的结合模式受体,主要是由于对 2 和 3 的柔性间隔基施加的构象限制。
