Anwendung

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. Wirkung

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.

Tryptophan administration aggravates experimental mouse liver injury caused by carbon tetrachloride when 3-hydroxyanthranilic acid concentration elevates in serum. Tryptophan metabolism is changed by macrophages in injured liver. 3-Hydroxyanthranilic acid may be oxidized to cinnabarinic acid by injured mitochondria in the

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.

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

A convenient and rapid method for the simultaneous determination by HPLC of 3-hydroxyanthranilic acid and the dimer derived by its oxidation, cinnabarinic acid, is described. Buffers or biological samples containing these two Trp metabolites were acidified to pH 2.0 and

The phenoxazinone chromophore occurs in a variety of biological systems, including numerous pigments and certain antibiotics. It also appears to form as part of a mechanism to protect mammalian tissue from oxidative damage. During cultivation of the basidiomycete, Pycnoporus cinnabarinus
