开发了手性池合成,以七到八步的顺序获得了所有四个立体异构体2-methyl-3-(4-phenylbutyl)tetrahydro-3-benzazepin-1-ols21,31,和32。酚类32表现出比甲醚21更高的GluN2B亲和力。GluN2B亲和力按(1R,2S)&(1S,2S)&(1S,2R)&(1R,2R)的顺序递增。立体异构体(R,R)-32和(S,R)-32表现出最高的GluN2B亲和力和最高的细胞保护活性。这两个化合物都是GluN2B选择性变构NMDA受体拮抗剂。将3-苯并卓-1-醇对接到结晶的GluN1b/GluN2B N-末端结构域的异芬普地尔结合位置上,得到了自由结合能,这与实验测定的GluN2B亲和力很好地关联。立体异构体苯酚(S,S)-32、(R,R)-32和(S,R)-32具有相似的GluN2B亲和力,这可以用3-苯扎西平支架的不同结合模式来解释。苄基醚31表现出出人意料的高GluN2B亲和力,但没有显示出细胞保护作用。额外的31个苄基结合到以前未被识别的亲脂子口袋中。
A chiral pool synthesis was developed to obtain all four stereoisomeric 2-methyl-3-(4-phenylbutyl)tetrahydro-3-benzazepin-1-ols21,31, and32in a seven- to eight-step sequence. The phenols32reveal slightly higher GluN2B affinity than the methyl ethers21. The GluN2B affinity increases in the order (1R,2S) < (1S,2S) < (1S,2R) < (1R,2R). The stereoisomeric phenols (R,R)-32and (S,R)-32show the highest GluN2B affinity and the highest cytoprotective activity. Both compounds represent GluN2B selective allosteric NMDA receptor antagonists. Docking of the 3-benzazepin-1-ols into the ifenprodil binding site of the crystallized GluN1b/GluN2B N-terminal domains led to free binding energies, which correlate nicely with the experimentally determined GluN2B affinities. The similar GluN2B affinity of the stereoisomeric phenols (S,S)-32, (R,R)-32, and (S,R)-32is explained by different binding modes of the 3-benzazepine scaffold. The benzyl ethers31reveal unexpectedly high GluN2B affinity but do not show cytoprotective effects. The additional benzyl moiety of31binds into a previously unrecognized lipophilic subpocket.
