Synthesis and NMD A Antagonistic Properties of the Enantiomers of 4-(3-phosphonopropyl)piperazine-2-carboxylic acid (CPP) and of the unsaturated analogue (E)-4-(3-phosphonoprop-2-enyl)piperazine-2-carboxylic acid (CPP-ene)

The (R)- and (s)-enantiomers of 4-(3-phosphonopropyl)piperazine-2-carboxylic acid (D- and L-CPP, resp.; 15 and 16, resp.), and of its unsaturated analogue (E)-4-(3-phosphonoprop-2-enyl)piperazine-2-carboxylic acid (D- and L-CPP-ene, resp.; 13 and 14, resp.) were prepared. The absolute configuration of the enantiomers was determined by a chemical correlation of the menthyl ester 7 with D-asparagine
4-(3-膦酰基丙基)哌嗪-2-羧酸的(R)和(s)-对映异构体(分别为D-和L-CPP;分别为15和16)及其不饱和类似物(制备E)-4-(3-膦酰基丙-2-烯基)哌嗪-2-羧酸(D-和L-CPP-烯,分别为13和14)。对映体的绝对构型由薄荷酯7与D-天冬酰胺的化学相关性确定。这些衍生物对NMDA受体的亲和力通过[ 3大鼠脑皮质膜中的H] CPP。在两项功能测试(青蛙半身脊髓制备和大鼠脑切片的钠流出测试)中,D-CPP-ene似乎是迄今为止已知最有效,对映体纯的竞争性NMDA拮抗剂。
