A series of new compounds containing a benzimidazole, benzothiazole, or benzoxazole nucleus linked to an arylpiperazine by different thioalkyl chains was prepared. They were tested in radioligand binding experiments to evaluate their affinity for 5-HT 1A and 5-HT 2A serotonergic, alpha 1 adrenergic, D1, and D2 dopaminergic receptors. Many of tested compounds showed an interesting binding profile; in
制备了一系列新化合物,其中包含通过不同的硫代烷基链与芳基哌嗪连接的苯并咪唑,苯并噻唑或苯并恶唑核。在放射性配体结合实验中对它们进行了测试,以评估它们对5-HT 1A和5-HT 2A血清素能,α1肾上腺素能,D1和D2多巴胺能受体的亲和力。许多测试化合物显示出有趣的结合特性;特别是,有36种化合物对5-HT 1A受体的亲和力和选择性高于所有其他研究受体。在功能测定中评估的选定化合物对5-HT 1A受体显示拮抗或部分激动活性。使用NMR和建模技术进行的广泛构象研究表明,在真空中,溶液中以及与5-HT 1A受体相互作用期间,扩展的构象占优势。最后,
