(+/-)-(Z)-2-(Aminomethyl)-1-phenylcyclopropane-N,N-diethylcarboxamide (milnacipran, 1), a clinically useful antidepressant, and its derivatives were prepared by an improved method and were evaluated as NMDA receptor antagonists. Of these, milnacipran (1), its N-methyl and N,N-dimethyl derivatives, 7 and 8, respectively, and its homologue 12 at the aminomethyl moiety had binding affinity for the receptor in vitro (IC50: 1, 6.3 +/- 0.3 mu M; 7, 13 +/- 2.1 mu M; 8, 88 +/- 1.4 mu M; 12, 10 +/- 1.2 mu M). These also protected mice from NMDA-induced lethality. These compounds would be important as anovel prototype for designing potent NMDA-receptor antagonists because of their characteristic structure, which clearly differentiated them from known competitive and noncompetitive antagonists to the receptor.
(±)-(Z)-2-(氨基甲基)-1-苯基环丙烷-N,N-二乙基酰胺(Milnacipran,1)是一种临床有效的抗抑郁药,其及其衍生物通过改进的方法制备,并作为NMDA受体拮抗剂进行了评估。其中,Milnacipran(1)、其N-甲基衍生物(7)和N,N-二甲基衍生物(8),以及氨基甲基部分的同系物(12)均对受体显示出结合亲和力(IC50:1为6.3 ± 0.3 μM;7为13 ± 2.1 μM;8为88 ± 1.4 μM;12为10 ± 1.2 μM)。这些化合物还保护小鼠免受NMDA诱导的致死性。由于其独特的结构,这些化合物可能作为设计高效NMDA受体拮抗剂的重要原型,明确地区别于已知的受体竞争性和非竞争性拮抗剂。
