Preparation and affinity to 5‐HT1A and 5‐HT2A receptors of new buspirone analogues 7–17 are reported. The compounds possess high to low affinity to 5‐HT1A and moderate to low to 5‐HT2A receptors. The crystal structures have been determined for compounds 11, 12, 13, and 14. For low affinity ligand (15) of 5‐HT1A receptor conformational analysis was performed and compared with similar analyses performed
报道了新丁螺环酮类似物 7-17 的制备和对 5-HT1A 和 5-HT2A 受体的亲和力。这些化合物对 5-HT1A 受体具有高到低的亲和力,对 5-HT2A 受体具有中到低的亲和力。已确定化合物 11、12、13 和 14 的晶体结构。对于 5-HT1A 受体的低亲和力配体 (15) 进行构象分析,并与对已知高 (丁螺环酮 1) 和非常高 (丁螺环酮 1) 进行的类似分析进行比较 ( WY-48, 723 2) 受体的亲和配体。讨论了对 5-HT1A 受体的亲和力的构效关系。提出了解释丁螺环酮类分子与受体结合位点相互作用的三点药效团。
