We report the synthesis of rigid spirocyclic systems as conformationally constrained variants of the Ala-Phe-NH2 dipeptide amide C-terminus of the calcitonin gene-related peptide (CGRP). CGRP receptor antagonists containing these moieties displayed potent affinity, functional antagonism and excellent oxidative stability. Structure–activity relationship studies demonstrated the relative importance of
我们报告了降钙素基因相关肽(CGRP)的Ala-Phe-NH 2二肽酰胺C末端构象受约束的变体的刚性螺环系统的合成。包含这些部分的CGRP受体拮抗剂表现出强的亲和力,功能拮抗作用和出色的氧化稳定性。结构与活性之间的关系研究表明,氢键供体/受体功能的相对重要性以及芳环的优选取向。拮抗剂显示CGRP诱导的离体人颅内动脉扩张有效而完全逆转。
