The synthesis of potent metabolically stable endocannabinoids is challenging. Here we report a chiral arachidonoyl ethanolamide (AEA) analogue, namely, (13S,1′R)-dimethylanandamide (AMG315, 3a), a high affinity ligand for the CB1 receptor (Ki of 7.8 ± 1.4 nM) that behaves as a potent CB1 agonist in vitro (EC50 = 0.6 ± 0.2 nM). (13S,1′R)-dimethylanandamide is the first potent AEA analogue with significant
有效代谢稳定的内源性大麻素的合成具有挑战性。在这里,我们报告了一种手性花生四烯酰乙醇酰胺 (AEA) 类似物,即 (13 S ,1' R )-二甲基茴香酰胺 (AMG315, 3a ),它是 CB1 受体的高亲和力配体 ( K i为 7.8 ± 1.4 nM),其行为如下体外有效的 CB1 激动剂 (EC 50 = 0.6 ± 0.2 nM)。(13 S ,1' R )-dimethylanandamide 是第一个对所有内源性大麻素水解酶以及氧化酶 COX-2 具有显着稳定性的强效 AEA 类似物。当使用 CFA 诱导的炎症性疼痛模型进行体内测试时,3a与内源性 AEA 或其水解稳定的类似物 AM356 相比,它是一种更有效的镇痛剂。这种新颖的类似物将作为一种非常有用的内源性大麻素探针。
