Cannabinoid CB receptor (CBR) agonists are investigated as therapeutic agents in the clinic. However, their molecular mode-of-action is not fully understood. Here, we report the discovery of LEI-102, a CBR agonist, used in conjunction with three other CBR ligands (APD371, HU308, and CP55,940) to investigate the selective CBR activation by binding kinetics, site-directed mutagenesis, and cryo-EM studies. We identify key residues for CBR activation. Highly lipophilic HU308 and the endocannabinoids, but not the more polar LEI-102, APD371, and CP55,940, reach the binding pocket through a membrane channel in TM1-TM7. Favorable physico-chemical properties of LEI-102 enable oral efficacy in a chemotherapy-induced nephropathy model. This study delineates the molecular mechanism of CBR activation by selective agonists and highlights the role of lipophilicity in CBR engagement. This may have implications for GPCR drug design and sheds light on their activation by endogenous ligands. 履歴 登録 2022年9月13日 - ヘッダ(付随情報) 公開 2023年5月10日 - マップ公開 2023年5月10日 - 更新 2023年5月24日 - 現状 2023年5月24日 処理サイト : PDBj / 状態 : 公開
