UH-232 ((+)-UH232) is a drug which acts as a subtype selective mixed agonist-antagonist for dopamine receptors, acting as a weak partial agonist at the D₃ subtype,^[1] and an antagonist at D₂Sh autoreceptors on dopaminergic nerve terminals.^[2][3][4] This causes dopamine release in the brain and has a stimulant effect,^[5][6][7] as well as blocking the behavioural effects of cocaine.^[8] It was trialled for the treatment of schizophrenia but unexpectedly caused symptoms to become worse.^[9]
