Kainic acid is a natural marine acid present in some algae. It is a specific agonist for the kainate receptor used as an ionotrophic glutamate receptor which mimicks the effect of glutamate. It is used in experiments to distinguish a receptor from the other ionotropic receptors for glutamate such as NMDA and AMPA, a.k.a. quisqualate.
In 1953, kainic acid was originally isolated from the red alga called "Kainin-sou"(海人草) or "Makuri" (Digenea simplex) in Japan. "Kainin-sou" is used as an anthelmintic in Japan.
Kainic acid is a potent central nervous system stimulant, and has been developed as the prototype neuroexcitatory amino acid for the induction of seizures in experimental animals, at a typical dose of 10-30 mg/kg in mice. Kainic acid is neuroexcitotoxic and epileptogenic, acting through specific kainate receptors. Because of the supply shortage in 2000, the price of kainic acid has risen significantly.
