Quisqualic acid is an agonist of the AMPA, kainate, and group I metabotropic glutamate receptors. It is one of the most potent AMPA receptor agonists known.[2][3][4][5] It causes excitotoxicity and is used in neuroscience to selectively destroy neurons in the brain or spinal cord.[6][7][8] Quisqualic acid occurs naturally in the seeds of Quisqualis species.

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.[9][10] Quisqualic acid is thought to mimic L-glutamic acid, which is a neurotransmitter in the insect neuromuscular junction and mammalian central nervous system.[11]
