antagonist. On the basis of the cyclopropane structure of (+/-)-1, conformationally restricted analogs with different stereochemistries, namely 1-phenyl-2-(1-aminoalkyl)-N,N-diethylcyclopropanecarboxamindes (2, 3, ent-2, and ent-3), were designed and synthesized. Among these analogs, 2a, 2b, and 2f, with (1S,2R,1'S)-configuration, were more efficient than milnacipran as NMDA receptor antagonists; these compounds
我们最近证明了(+/-)-(Z)-2-(氨基甲基)-1-苯基-N,N-二乙基环丙烷甲酰胺[milnacipran,(+/-)-1]是5-羟色胺再摄取的抑制剂(5 -HT)是非竞争性NMDA受体拮抗剂。根据(+/-)-1的环丙烷结构,构象受限的类似物具有不同的立体化学,即1-苯基-2-(1-氨基烷基)-N,N-二乙基环丙烷甲酰胺(2,3,ent-2,和ent-3),进行了设计和合成。在这些类似物中,具有(1S,2R,1'S)构型的2a,2b和2f比milnacipran作为NMDA受体拮抗剂更有效。这些化合物分别在IC50 = 0.35 +/- 0.08、0.20 +/- 0.024和0.16 +/- 0.02 microM时显着抑制[3H] MK-801的结合,并阻断了电压钳型卵母细胞对NMDA的反应,超过(+/-)-1的效果。
