1 Inhibitors of kynurenine 3-hydroxylase have previously been used to increase endogenous levels of kynurenic acid, an excitatory amino acid receptor antagonist. Kynurenic Acid kynurenine 3-monooxygenase Rattus norvegicus
2 The results of the present study show that a moderate increase in endogenous kynurenic acid levels produces significant actions on the tonic glutamatergic control of the firing pattern of nigral DA neurons, and implicate kynurenine 3-hydroxylase inhibitors as novel antiparkinsonian agents. Kynurenic Acid kynurenine 3-monooxygenase Rattus norvegicus
