A series of [2-(ω-phenylalkyl)phenoxy]alkylamines was synthesized and thir receptor binding affinity was examined in vitro. These compounds showed an affinity for serotonin-2 (5-HT2) and dopamine-2 (D2) receptors. [2-(2-phenylethyl)phenoxy]alkylamine derivatives with a pyrrolidine or piperidine moiety in the structure showed higher affinity for 5-HT2 receptors but lower affinity for D2 receptors. Among these compounds, (S)-2-[2-[2-[2-(3-methoxyphenyl)ethyl]phenoxy]ethyl]1-methylpyrrolidine, (S)-27, exhibited the most potent and selective affinity for 5-HT2 receptors. Furthermore, (S)-27 was effective in inhibiting 5-HT-induced vasoconstriction in vitro and platelet aggregation both in vitro and ex vivo.
合成了一系列[2-(ω-苯基烷基)苯氧]烷基胺,并在体外检测了它们的受体结合亲和力。这些化合物显示出对血清素-2(5-HT2)和多巴胺-2(D2)受体的亲和力。在结构中含有吡咯烷或哌啶基团的[2-(2-苯乙基)苯氧]烷基胺衍生物对5-HT2受体表现出更高的亲和力,但对D2受体的亲和力较低。在这些化合物中,(S)-2-[2-[2-[2-(3-甲氧基苯基)乙基]苯氧]乙基]1-甲基吡咯烷((S)-27)显示出对5-HT2受体最具效力和选择性的亲和力。此外,(S)-27在体外有效抑制了5-HT引起的血管收缩和血小板聚集,无论是体外还是离体实验中均表现出了效果。
