The mGluR7 allosteric agonist AMN082 produces antidepressant-like effects by modulating glutamatergic signaling.

Currently prescribed antidepressants affect the reuptake and/or metabolism of biogenic amines. Unfortunately for patients, these treatments require several weeks to produce significant symptom remission. However, recently it has been found that ketamine, a dissociative anesthetic agent that noncompetitively antagonizes NMDA (N-Methyl-d-aspartic acid) receptors, has rapid antidepressant effects at sub-anesthetic doses in clinically depressed patients.
