Metabolite Identification
Common NameMolindone
DescriptionAn indole derivative effective in schizophrenia and other psychoses and possibly useful in the treatment of the aggressive type of undersocialized conduct disorder. Molindone has much lower affinity for D2 receptors than most antipsychotic agents and has a relatively low affinity for D1 receptors. It has only low to moderate affinity for cholinergic and alpha-adrenergic receptors. Some electrophysiologic data from animals indicate that molindone has certain characteristics that resemble those of clozapine. (From AMA Drug Evaluations Annual, 1994, p283)

General function:
Involved in G-protein coupled receptor protein signaling pathway
Specific function:
This is one of the several different receptors for 5- hydroxytryptamine (serotonin), a biogenic hormone that functions as a neurotransmitter, a hormone, and a mitogen. This receptor mediates its action by association with G proteins that activate a phosphatidylinositol-calcium second messenger system. This receptor is involved in tracheal smooth muscle contraction, bronchoconstriction, and control of aldosterone production
