Tepirindole (INNTooltip International Nonproprietary Name; developmental code names RU-27592, HR-592) is a tryptamine-related atypical antipsychotic and major tranquilizer which was never marketed.[1][2][3][4][5] It is similar in structure to tryptamines but is not technically a tryptamine itself and is instead a piperidinyl indole.[1][6] The drug is said to act on dopamine D2, serotonin 5-HT2, and α1-adrenergic receptors.[3][4] It is a potent dopamine receptor antagonist but reportedly has little propensity to cause catalepsy and has been said to potentially be useful in treating the negative symptoms of schizophrenia.[4][5] The drug may also act as a potent serotonin receptor agonist.[6] Tepirindole was first described in the literature by 1979.[1][6]

Tepirindole (HR-592, 25) has a high affinity for DA, 5-HT and NE receptors but has little propensity to cause catalepsy (78).
