Y-23684 is ananxiolytic drug with a novel chemical structure, which is used in scientific research.[1][2] It has similar effects tobenzodiazepine drugs, but is structurally distinct and so is classed as anonbenzodiazepine anxiolytic.
Y-23684 is a nonselectivepartial agonist atGABAAreceptors. It has primarilyanxiolytic andanticonvulsant effects, withsedative andmuscle relaxant effects only appearing at higher doses. It produces littleataxia or potentiation of other sedatives such as ethanol or barbiturates when compared to the benzodiazepinesdiazepam andclobazam in animal tests.[3][4][5]
Y-23684 has a favourablepharmacological profile, producing strong anxiolytic and moderate anticonvulsant effects at low doses that cause little or no sedative side effects. It has been proposed for development for human medical use, but has not yet gone beyond animal tests.[6]
