SCH-23390 can abolish generalized seizures evoked by the chemoconvulsants: pilocarpine and soman. SCH-23390 has also been used in studies of other neurological disorders in which the dopamine system has been implicated, such as psychosis and Parkinson's disease. Apart from the study of neurological disorders, SCH-23390 has been extensively used as a tool in the topographical determination of brain D₁ receptors in rodents, nonhuman primates, and humans^[1].
SCH-23390 is a very short-acting compound with an elimination half-life of around 25 min following administration of 0.3 mg/kg i.p. in the rat^[1].
SCH-23390 augments dopamine-induced ductus constriction in CD-1 mouse vessels under newborn O₂ conditions^[5].
