Research Area: Depressive disorders
Biological Activity:
Agomelatine is an antidepressant drug. It is classified as a norepinephrine-dopamine disinhibitor (NDDI) due to its antagonism of the 5-HT2C receptor. Activation of 5-HT2C receptors by serotonin inhibits dopamine and norepinephrine release. Antagonism of 5-HT2C results in an enhancement of DA and NE release and activity of frontocortical dopaminergic and adrenergic pathways. [1]Agomelatine is also a potent agonist at melatonin receptors which makes it the first melatonergic antidepressant.

Biochem/physiol Actions
Agomelatine is an extremely potent agonist at both melatonin receptors (MT1 and MT2), with additional antagonism at 5HT2C. It is a novel antidepressant with many desired in vivo properties, including neuroprotection and neurogenesis in depression-sensitive brain areas. Agomelatine′s efficacy appears to be due to both melatonergic and serotonergic properties. In neurogenesis assays, both in vitro and in vivo, the compound effects were differentially affected by antagonists for MT1/MT2 and 5HT2C, demonstrating actions through all three receptors.

Agomelatine is a melatoninergic agonist and selective antagonist of 5-HT2C receptors, and has been shown to be active in several animal models of depression. Agomelatine (S20098) displayed pKi values of 6.4 and 6.2 at native (porcine) and cloned, human
