Quisqualic acid is an agonist of the AMPA, kainate, and group I metabotropic glutamate receptors, and one of the most potent AMPA receptor agonists known.[1][2][3][4] It causes excitotoxicity and is used in neuroscience to selectively destroy neurons in the brain or spinal cord.[5][6][7] Quisqualic acid occurs naturally in the seeds of Quisqualis species.[α] 20D = +17 (6M HCl)

Research conducted by the USDA Agricultural Research Service, has demonstrated quisqualic acid is also present within the flower petals of zonal geranium (Pelargonium x hortorum) and is responsible for causing rigid paralysis of the Japanese beetle.[8][9] Quisqualic acid is thought to mimic L-glutamic acid, which is a neurotransmitter in the insect neuromuscular junction and mammalian central nervous system.[10]
