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.

Since 3-hydroxyanthranilic acid (3HAA), an oxidation product of tryptophan metabolism, is a powerful radical scavenger [Christen, S., Peterhans, E., & Stocker, R. (1990) Proc. Natl. Acad. Sci. U.S.A. 87, 2506], its reaction with peroxyl radicals was investigated further. Exposure to

When glucose is the carbon source, the white rot fungus Pycnoporus cinnabarinus produces a characteristic red pigment, cinnabarinic acid, which is formed by laccase-catalyzed oxidation of the precursor 3-hydroxyanthranilic acid. When P. cinnabarinus was grown on media containing cellobiose or

Superoxide dismutase (SOD) enhanced the formation of hydroxyl radicals, which were detected by using the e.s.r. spin-trapping technique, in a reaction mixture containing 3-hydroxyanthranilic acid (or p-aminophenol), Fe3+ ions, EDTA and potassium phosphate buffer, pH 7.4. The hydroxyl-radical formation enhanced

Discover Bioactive Small Molecules for Apoptosis

Apoptosis, or programmed cell death (PCD), is a selective process for the removal of unnecessary, infected or transformed cells in various biological systems. As it plays a role in the homeostasis of multicellular organisms, apoptosis is tightly regulated through two principal pathways by a number of regulatory and effector molecules.
