Definition:A quinolinemonocarboxylic acid that is quinaldic acid which is substituted by a hydroxy group at position 4 and by a chlorine at position 7. It is a potent NMDA glutamate receptor antagonist which antagonizes the strychnine-insensitive glycine site of the NMDA receptor. It also prevents neurodegeneration produced by quinolinic acid.
