7-Chlorokynurenic acid is an NMDA receptor antagonist acting at the glycine site. 7-Chlorokynurenic acid acts as a potent competitive inhibitor of EAAT (L-glutamate transporter) into synaptic vesicles. 7-Chlorokynurenic acid is derived from kynurenic acid, a natural metabolite of tryptophan found in the mammalian brain. This compound has shown the ability to regulate NMDA receptor-mediated excitotoxicity.
