NMDA receptor

描述

Kynurenic acid (KYNA) is an endogenous antagonist of glutamate in the central nervous system. It is most active as an antagonist at receptors sensitive to N‐methyl‐D‐aspartate (NMDA) which regulate neuronal excitability and plasticity, brain development and behaviour^[3]. Peripheral administration of kynurenic acid, at a dose that caused plasma levels to increase 430-fold, resulted in only 4-fold increases in striatal ECF(extracellular fluid) concentrations^[4]. KYNA has a significant protective effect on liver injury induced by thioacetamide (TAA)^[5].
