Homoquinolinic acid (HQA) is a potent excitotoxin[1] which is a conformationally-restricted analogue of N-methyl-D-aspartate (NMDA) and a partial agonist of the main/glutamate site of the NMDA receptor, with some selectivity for NR2B subunit-containing receptors.[2][3][4] It is approximately equipotent to NMDA and about five times more potent than quinolinic acid as an agonist of the NMDA receptor.[5] HQA has also been found to label a novel, yet uncharacterized binding site, which can be distinguished from the NMDA receptor with the use of 2-carboxy-3-carboxymethylquinoline (CCMQ), a selective ligand of the uncharacterized site.[6]
