developed compounds have high affinity and specificity for cannabinoid CB1 and CB2 receptors. Compound 25 is a potent CB1 and CB2 ligand, with affinity constants significantly lower than AEA and similar to WIN 55-212, compound 52 is a potent CB2 ligand, although not very selective over CB1 receptors, and compound 43 is CB2 ligand, with at least a 26-fold selectivity over CB1 receptors. Compound 25 behaved
尽管它们的化学结构不同,delta9-四氢大麻酚(THC)和阿南酰胺(AEA)具有共同的药理特性。这项研究旨在寻找克服AEA及其类似物不稳定性的新型大麻素受体配体。为此,我们计划合成一系列化合物,这些化合物既保留了植物大麻素的刚性结构,又保留了类似于anandamide的柔性部分。对CB1和CB2受体,阿南酰胺膜转运蛋白(AMT)和脂肪酸酰胺水解酶(FAAH)的结合研究表明,一些新开发的化合物对大麻素CB1和CB2受体具有很高的亲和力和特异性。化合物25是有效的CB1和CB2配体,其亲和常数明显低于AEA,与WIN 55-212类似,化合物52是有效的CB2配体,尽管化合物对CB1受体的选择性不是很高,但化合物43是CB2配体,其选择性比CB1受体至少高26倍。化合物25在循环AMP功能试验中对CB1受体起反向激动剂的作用。
