We investigated the structure-activity relationships for the interactions of fatty acid amide analogs of the endocannabinoid anandamide with human recombinant cannabinoid receptors. Thirty-five novel fatty acid amides were synthesized using five different types of acyl chains and 11 different aromatic amine 'heads.' Although none of the new compounds was a more potent ligand than anandamide, we identified
我们调查了内源性大麻素南and酰胺的脂肪酸酰胺类似物与人重组大麻素受体相互作用的构效关系。使用五种不同类型的酰基链和11种不同的芳香胺“头”合成了35种新型脂肪酸酰胺。尽管没有一种新化合物比anandamide具有更强的配位体,但我们确定了三个能够改善花生四烯酰胺的代谢稳定性及其CB(1)/ CB(2)选择性比超过20倍的胺基,以及几种芳香族胺能够提高短链或单饱和脂肪酸对大麻素CB(1)受体的亲和力。首次发现花生四烯酸叔酰胺对大麻素CB(1)受体具有中等亲和力(K(i)= 300 nM),但对CB(2)受体不具有中等亲和力。
