Application

Cinnabarinic acid may be used in studies of the functions of components of the kynurenine metabolic pathway. It may be used to study it role as a metabotropic glutamate receptor (mGlu4R-specific) agonist.

Biochem/physiol Actions

Caspase Inducer; mGlu4R agonist
Cinnabarinic acid (CA) connects between initiation of the kynurenine pathway and immune tolerance that is used to prevent neuroinflammation.
Cinnabarinic acid is a kynurenine pathway metabolite of tryptophan, produced by the oxidation of 3-Hydroxyanthranilic acid. Cinnabarinic acid leads to loss of mitochondrial respiration and apoptosis, and has also been shown to be an mGlu4R-specific agonist.
