4-Bromomethcathinone (4-BMC, Brephedrone) is a psychoactive drug and research chemical of the phenethylamine, amphetamine, and cathinone chemical classes. It acts as a serotonin and norepinephrine reuptake inhibitor,[1][2] but acts more like an antidepressant than a stimulant.[3] It is currently unclear whether the 4-halogenated cathinones share the selective serotonergic neurotoxicity of their corresponding amphetamines.
