LY2140023 is an investigational drug from Lilly, which is being developed as a new treatment option for schizophrenia. LY2140023 is an oral "prodrug," meaning it is devoid of intrinsic biological activity and, once administered, is metabolized to provide the active mGlu2/3 receptor agonist called LY404039. Most currently approved antipsychotic medications work by affecting the neurotransmitters dopamine or serotonin. For LY2140023, the active substance, LY404039, is thought to work by reducing the presynaptic release of another neurotransmitter, glutamate, in brain regions where mGlu2/3 receptors are expressed. Further studies are planned or are ongoing to learn more about the safety and effectiveness, including determining an optimal therapeutic dose for LY2140023.

LY2140023 is an antipsychotic agent that is a metabotropic glutamate 2/3 receptor agonist. This agent has a new mechanism of action that is efficacious in treating schizophrenia and potentially other neuropsychiatric conditions. Once absorbed, LY2140023 is efficiently hydrolyzed to produce the active mGlu2/3 receptor agonist LY404039. LY404039 and other mGlu2/3 agonists do not directly interact with dopamine or serotonin (5-HT2A) receptors. However, 'functional' 5-HT2A receptor antagonism in the prefrontal cortex may represent a common mechanism shared by clinically effective atypical antipsychotics and mGlu2/3 receptor agonists, and may contribute to the antipsychotic actions of LY2140023.
Investigated for use/treatment in psychosis and schizophrenia and schizoaffective disorders.
