HCAR2 ... Hydroxycarboxylic acid receptor 2 (HCAR2), modulated by endogenous ketone body β-hydroxybutyrate and exogenous niacin, is a promising therapeutic target for inflammation-related diseases. HCAR2 mediates distinct pathophysiological events by activating G protein or β-arrestin effectors. Here, we characterize compound 9n as a G-biased allosteric modulator (BAM) of HCAR2 and exhibit anti-inflammatory efficacy in RAW264.7 macrophages via a specific HCAR2-G pathway. Furthermore, four structures of HCAR2-G complex bound to orthosteric agonists (niacin or monomethyl fumarate), compound 9n, and niacin together with compound 9n simultaneously reveal a common orthosteric site and a unique allosteric site. Combined with functional studies, we decipher the action framework of biased allosteric modulation of compound 9n on the orthosteric site. Moreover, co-administration of compound 9n with orthosteric agonists could enhance anti-inflammatory effects in the mouse model of colitis. Together, our study provides insight to understand the molecular pharmacology of the BAM and facilitates exploring the therapeutic potential of the BAM with orthosteric drugs. 履歴 登録 2023年5月26日 - ヘッダ(付随情報) 公開 2023年9月6日 - マップ公開 2023年9月6日 - 更新 2024年10月30日 - 現状 2024年10月30日 処理サイト : PDBj / 状態 : 公開
