We report the development and extensive structure-activity relationship evaluation of a series of modified coumarins as cannabinoid receptor ligands. In radioligand, and [35S]GTPγS binding assays the CB receptor binding affinities and efficacies of the new ligands were determined. Furthermore, we used a ligand-based docking approach to validate the empirical observed results. In conclusion, several
我们报告了一系列作为大麻素受体配体的修饰香豆素的开发和广泛的构效关系评估。在放射性配体和 [ 35 S] GTPγS 结合测定中,确定了新配体的 CB 受体结合亲和力和功效。此外,我们使用基于配体的对接方法来验证经验观察结果。总之,确定了几个关键的结构要求。最有效的香豆素,如 3-丁基-7-(1-丁基环戊基)-5-羟基-2H-chromen-2-one ( 36b , K i CB 2 13.7 nM, EC 50 18 nM), 7-(1-丁基环己基)-5-羟基-3-丙基-2H-chromen-2-one ( 39b , K iCB 2 6.5 nM,EC 50 4.51 nM)显示具有低纳摩尔亲和力的CB 2选择性激动特性。
