A screening of conformationally constrained aromatic amino acids as base cores for the preparation of new NK1 receptor antagonists resulted in the discovery of three new NK1 receptor antagonists, 19 [Ac-Aba-Gly-NH-3′,5′-(CF3)2-Bn], 20 [Ac-Aba-Gly-NMe-3′,5′-(CF3)2-Bn], and 23 [Ac-Tic-NMe-3′,5′-(CF3)2-Bn], which were able to counteract the agonist effect of substance P, the endogenous ligand of NK1R
筛选构象受限的芳香族氨基酸作为制备新 NK1 受体拮抗剂的基础核心,发现了三种新的 NK1 受体拮抗剂,19 [Ac-Aba-Gly-NH-3',5'-(CF 3 ) 2 -Bn]、20 [Ac-Aba-Gly-NMe-3',5'-(CF 3 ) 2 -Bn] 和23 [Ac-Tic-NMe-3',5'-(CF 3 ) 2 -Bn],能够抵消物质 P(NK1R 的内源性配体)的激动作用。该系列中最活跃的 NK1 拮抗剂,20 [Ac-Aba-Gly-NMe-3',5'-(CF 3 ) 2-Bn],然后用于设计一种新型、有效的嵌合阿片类激动剂-NK1受体拮抗剂,35 [Dmt - d -Arg-Aba-Gly-NMe-3',5'-(CF 3 ) 2 -Bn ],它结合了已建立的 Dmt 1 -DALDA 激动剂阿片类药效团(H- Dmt - d -Arg-Phe-Lys-NH 2)和20的 N
