Cycloalkanecarboxamido)ethyl‐1‐(2‐methoxyphenyl)piperazin es 8a–c, 8e, and 8h were obtained by acylation of 4‐(2‐aminoethyl)‐1‐(2‐methoxyphenyl)piperazine, and their 5‐HT1A, 5‐HT1A, 5‐HT2A and α receptor affinities were determined. It was found that the terminal cycloalkane moiety strongly stabilizes both the 5‐HT1A and 5‐HT2A receptor‐ligand complexes. It was demonstrated that the most active 5‐HT1A
环烷甲酰胺基)乙基-1-(2-甲氧基苯基)哌嗪es 8a-c、8e和8h是通过4-(2-氨基乙基)-1-(2-甲氧基苯基)哌嗪和它们的5-HT1A,5酰化得到的测定了-HT1A、5-HT2A和α受体亲和力。发现末端环烷烃部分强烈稳定 5-HT1A 和 5-HT2A 受体-配体复合物。结果表明,最活跃的 5-HT1A 配体 8e 和 8h(分别为 Ki = 2.1 和 0.21 nM)充当这些受体的有效激动剂,即这两种衍生物在下唇收缩 (LLR) 模型中都模拟了 8-OH-DPAT并且该作用易于被合理剂量的选择性 5-HT1A 受体拮抗剂 (S)-WAY-100135 阻断。
