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] It 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 may also serve as a 5-HT2A receptor agonist, based on animal studies.[9] It was investigated in clinical trials for the treatment of schizophrenia, but unexpectedly caused symptoms to become worse.[9]
