The enantiomers of cis-(±)-methyl (1R,2S/1S,2R)-2-[(4-hydroxy-4-phenylpiperidin-1-yl)methyl]-1-(4-methylphenyl)cyclopropanecarboxylate [1, (±)-PPCC], a selective σ ligand, were synthesized. The (+)- and (−)-enantiomers bind predominantly to σ1 receptors and have a reduced σ2 affinity. Both individually restore the astroglial oxidative status modified by glutamate, counteracting also transglutaminase-2
的对映体顺式- (±) -甲基(1 - [R,2小号/ 1小号,2 - [R)-2 - [(4-羟基-4-苯基哌啶-1-基)甲基] -1-(4-甲基苯基)合成了选择性的σ配体环丙烷羧酸酯[ 1,(±)-PPCC]。的(+) -和( - ) -对映异构体结合主要对σ 1个受体和具有降低的σ 2的亲和力。两者都可以单独恢复由谷氨酸修饰的星形胶质细胞的氧化状态,也可以抵消转谷氨酰胺酶2的过表达。他们对κ阿片样物质(KOP)受体介导的镇痛表现出体内抗阿片样物质作用。我们的研究结果表明,对映异构体显示主要σ 1 激动剂活性,并且它们具有神经保护作用。
