r-sch23390 maleate

SCH-23390 maleate (R-(+)-SCH-23390 maleate) is a potent and selective dopamine D1-like receptor antagonist, specifically targeting D1 and D5 receptors with Ki values of 0.2 nM and 0.3 nM, respectively.

SCH-23390 is a dopamine D1-like receptor antagonist (with Ki values of 0.2 nM for the D1 receptor subtype and 0.3 nM for the D5 receptor subtype). It reduces the latency of lever pressing behavior induced by cocaine in rats. Additionally, SCH-23390 can eliminate generalized seizures triggered by the chemical convulsants pilocarpine and soman, making it useful for studies on neurodegenerative diseases related to the dopamine system.
