Kynurenic acid is a natural metabolite of tryptophan via the kynurenine pathway. It has pronounced effects on neuronal signaling and, thus, impacts diverse neurological systems.{27403,27404} Kynurenic acid broadly antagonizes ionotopic glutamate receptors at high micromolar to millimolar concentrations and is used to pharmacologically block the activation of these receptors in vivo or in vitro.{27407} In addition, it reportedly has more potent effects at glutamate receptor subunit ζ-1 (Ki = 5.4 µM), GPR35 (EC50 = 39 µM), aryl hydrocarbon receptor (EC50 = 300 nM), and neuronal acetylcholine receptor α-7 (IC50 = 7 µM).{27405,14771,27406,27404}
