Hypidone (developmental code name YL-0919) is an investigational serotonergic antidepressant which is under development for the treatment of major depressive disorder.[1][2][3][4][5] It acts as a serotonin reuptake inhibitor, 5-HT1A receptor partial agonist, and 5-HT6 receptor full agonist.[1][5] It is used as the hydrochloride salt.[2][5] As of January 2021, hypidone is in phase 2 clinical trials for major depressive disorder.[1]
