Neuroprotective effect of excitatory amino acid antagonist kynurenic acid in experimental bacterial meningitis [PDF]
, 1996 Sustained high-level exposure to glutamate, an excitatory amino acid neurotransmitter, leads to neuronal death. Kynurenic acid attenuates the toxic effects of glutamate by inhibition of neuronal excitatory amino acid receptors, including the N-methyl-D ...

Reactions of kynurenic acid with hypobromous acid and hypochlorous acid
Journal of Clinical Biochemistry and Nutrition, 2021 Kynurenic acid, a tryptophan metabolite, acts as antagonist or agonist of several receptors. Hypobromous acid (HOBr) and hypochlorous acid (HOCl) are generated by eosinophils and neutrophils. At inflammation sites, kynurenic acid may encounter HOBr and HOCl to generate products.
