this work, we sought to identify novel NPFF receptors ligands by focusing our interest in a series of heterocycles as rigidified nonpeptide NPFF receptor ligands, starting from already described aminoguanidine hydrazones (AGHs). Binding experiments and functional assays highlighted AGH 1n and its rigidified analogue 2-amino-dihydropyrimidine 22e for in vivo experiments. As shown earlier with the prototypical
先前已显示神经肽FF受体(NPFF1R和NPFF2R)及其内源性配体神经肽FF具有抗阿片类药物的特性,并且在鸦片类药物长期服用相关的不良反应中起关键作用,包括阿片类药物引起的痛觉过敏和镇痛耐受性的发展。在这项工作中,我们试图通过将我们的注意力集中在一系列杂环上来鉴定新的NPFF受体配体,这些杂环作为刚性化的非肽NPFF受体配体,从已经描述的氨基胍(AGH)开始。结合实验和功能测定突出了用于体内实验的AGH 1n及其刚性化类似物2-氨基-二氢嘧啶22e。如先前使用原型二肽拮抗剂RF9所示,1n和22e均显着降低了芬太尼诱导的鼠持久性痛觉过敏。总而言之,这些数据表明,AGH硬化对两种NPFF受体均保持纳摩尔亲和力,同时改善了对NPFF1R的拮抗特性。
