| Hazard Information | Back Directory | [Uses]
Kynurenic acid has been used as a constituent in dissection saline solution for embryonic cerebral cortical cells and human primary astrocytes. It has also been used as a medium supplement for murine intestinal epithelial cell line, MODE-K and induced pluripotent stem cell (iPSC)-derived neurons cells. | [Uses]
A product of L-Tryptophan metabolism, possessing neruoactive activity having antiexcitotoxic and anticonvulsant properties. | [Uses]
An antagonist of NMDA and AMPA/kainate receptors | [Definition]
ChEBI: Kynurenic acid is a quinolinemonocarboxylic acid that is quinoline-2-carboxylic acid substituted by a hydroxy group at C-4. It has a role as a G-protein-coupled receptor agonist, a NMDA receptor antagonist, a nicotinic antagonist, a neuroprotective agent, a human metabolite and a Saccharomyces cerevisiae metabolite. It is a monohydroxyquinoline and a quinolinemonocarboxylic acid. It is a conjugate acid of a kynurenate. | [Biological Activity]
Broad spectrum EAA antagonist. | [Biochem/physiol Actions]
Kynurenic acid (KynA) is a non-selective antagonist of N-methyl-d-aspartate (NMDA), α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) and kainate receptors. It blocks kainic acid neurotoxicity. Kynurenic acid also blocks nicotinic acetylcholine receptors. It is a by-product of tryptophan catabolic pathway. Kynurenic acid is a neuromodulator and controls the levels of glutamate, dopamine, acetylcholine and α-aminobutyric acid (GABA). KynA controls neuroendocrine functions and altered levels of KynA is a potential marker in depression, schizophrenia Alzheimer′s and Huntington′s diseases. Normal levels of KynA in the brain is crucial for the cognitive function. | [storage]
