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.

Concentrated culture fluid of the wood-rotting basidiomycete Pycnoporus cinnabarinus showed biological activity against a variety of bacterial strains. The maximal inhibitory effect was obtained for Gram-positive bacteria of the genus Streptococcus. In general, inhibition was higher for Gram-positive than Gram-negative

The oxidative reactivities of four tryptophan metabolites in the kynurenine pathway were examined as a potential mechanism for their reported neurotoxicities and carcinogenicities. Neither quinolinic acid, a neurotoxin, nor its monocarboxylic analogue, picolinic acid, auto-oxidized over a wide pH range.

The autoxidation of the tryptophan metabolite, 3-hydroxyanthranilic acid, at pH 7 gives rise to a p-quinone dimer and cinnabarinic acid. A novel dimer formed by radical-radical coupling of 3-hydroxyanthranilic acid is also produced. Labelling studies have shown that the C-2

Cinnabarinic acid was formed from 3-hydroxyanthranilic acid during incubation with a soluble fraction from Malpighian tubules of the silkworm, Bombyx mori, in the presence of manganese ion. The enzyme having this activity was purified to homogeneity by ammonium sulfate fractionation
