Using rimonabant, a potent inverse agonist for cannabinoid receptor type 1 (CB1R), as parent ligand, a series of novel univalent and bivalent ligands were designed by variation of spacer length and its chemical structure. The ligands synthesized were evaluated for affinity and selectivity by radioligand displacement and a functional steady-state GTPase assay. The results showed the nature of the spacer
使用1型大麻素受体(CB 1 R)的强效反向激动剂利莫那班作为母体配体,通过改变间隔区的长度及其化学结构,设计了一系列新颖的单价和二价配体。通过放射性配体置换和功能性稳态GTPase分析评估合成的配体的亲和力和选择性。结果表明,间隔子的性质会影响生物学读数。尽管所有化合物的亲和力均显着低于利莫那班,但这一事实可用于证明亲和力和选择性受间隔物的化学结构和长度影响,并可能有助于设计其他GPCR受体的二价探针。
