The design and synthesis of new N1‐substituted 3‐carboxy‐ and 3‐phosphonopyrazoline and pyrazole amino acids that target the glutamate binding site of NMDA receptors are described. An analysis of the stereochemical requirements for high‐affinity interaction with these receptors was performed. We identified two highly potent and selective competitive NMDA receptor antagonists, (5S,αR)‐1 and (5S,αR)‐4
描述和设计了新的N1取代的3-羧基和3-膦基吡唑啉和吡唑氨基酸,它们靶向NMDA受体的谷氨酸结合位点。对与这些受体的高亲和力相互作用的立体化学要求进行了分析。我们确定了两个高度有效和选择性的竞争性NMDA受体拮抗剂,(5小号,α - [R )- 1和(5小号,α - [R ) - 4,它显示出良好的体外神经保护活性和在通过腹膜内施用体内抗惊厥活性,这表明这些分子可能具有潜在的治疗作用。
