Quizapine is a piperazine-based nonselective serotonin (5-HT) receptor agonist with antidepressant and oxytocic activities. Quipazine targets and binds to serotonin receptors, particularly to the 5HT2A and 5HT3 receptors. Quipazine is a potential anti-parkinsonian agent. Serotonin receptor activation by quipazine may lead to smooth muscle contraction and antidepressant effects. quipazine, a central serotonergic agent, counteracted some of the drug-induced symptoms of pseudoparkinsonism in laboratory animals. Cholinergic, dopaminergic and histaminergic receptors play an important role in the manifestations of these symptoms.

Sample Use Guides

In Vivo Use Guide

Rats: Quipazine increased serum corticosterone within 30 min after its i.p. injection (at 10 mg/kg) into rats. Elevation of serum corticosterone did not occur with a 1.25 mg/kg dose of quipazine but was dose-related over a 2.5-20 mg/kg dose range.

In Vitro Use Guide

Quipazine (3.1 x 10(-7)-10(-4) M) caused concentration-dependent contractions of the canine basilar artery.
