(1S,2R)-1-Phenyl-2-[(S)-1-aminopropyl]-N,N-diethylcyclopropanecarboxamide (2b), which is a conformationally restricted analog of the antidepressant milnacipran [(±)-1], is a new class of potent NMDA (N-methyl-D-aspartic acid) receptor antagonists. A series of analogs of 2b modified at the 1′-position were designed and synthesized starting from (R)-epichlorohydrin via the key intermediate an optically
(1 S,2 R)-1-苯基-2-[(S)-1-氨基丙基] -N,N-二乙基环丙烷甲酰胺(2b),其为抗抑郁药米那普仑[(±)-1 ]的构象受限类似物。,是一类新的有效的NMDA(N-甲基-D-天冬氨酸)受体拮抗剂。一系列的类似物的图2b的1'-位修饰设计并合成从(起始- [R )-环氧氯丙烷经由关键中间体的光学活性的环丙烷甲醛衍生物8使用(1小号,2 - [R)-配置。在这些类似物中,(1 S,2 R)-1-苯基-2-[(S)-1-氨基丁-3-烯基] -N,N-二乙基环丙烷甲酰胺(2i)和(1 S,2 R)-1 -苯基-2-[(S)-1-氨基丁-3-炔基] -N,N-二乙基环丙烷甲酰胺(2j)被确定为比2b更有效的NMDA受体拮抗剂。研究了2i和2j以及2b的亚型选择性,结果表明2i抑制GluRε3/ζl和GluRε4/ζl亚型的强度是GluRε1/ζl和GluRε2/ζl亚型的四倍。化
