increasing the inhibitory potency of the analgesic dipeptide H‐Trp(Nps)‐Lys‐OMe against enkephalin‐degrading aminopeptidases, the following derivatives bearing chelating groups at the N‐terminus have been synthesized: Ac‐Trp(Nps)‐Lys‐OMe (3), HS(CH2)nCO‐Trp(Nps)‐Lys‐OMe [n = 1 (4), n = 2 (5)], MeOCO(CH2)n‐Trp(Nps)‐Lys‐OMe [n = 1 (6), n = 2 (7)] and analogues in which the Nα‐amino group has been replaced
为了提高镇痛二肽 H-Trp (Nps)-Lys-OMe 对脑啡肽-降解氨肽酶的抑制效力,合成了以下在 N-末端带有螯合基团的衍生物:Ac-Trp (Nps)- Lys - OMe (3), HS (CH2) nCO - Trp (Nps) -Lys - OMe [n = 1 (4), n = 2 (5)], MeOCO (CH2) n - Trp (Nps) -Lys- OMe [n = 1 (6), n = 2 (7)] 和 Nα-氨基分别被甲氧基羰基 (8) 和双齿异羟肟酸酯官能团 (9) 取代的类似物。所有这些化合物和 S-保护的衍生物 EtNHCOS (CH2) nCO-Trp (Nps) -Lys-OMe [n = 1 (16), n = (17)] 对上述酶的抑制活性,从大鼠纹状体中分离, 与亲本二肽 2 和贝他汀的那些进行比较。总的来说,所有新的衍生品都表明,
