( 2S , 3S , 4S )-2-carboxy-4-isopropenyl-3-pyrrolidineacetic acid . C10H15NO4 (213.23). ( -)-α-Kainic acid found in the red alga Digenea simplex . It has physiological activity as an anthelmintic, and was previously used in mass anthelmintics at primary and secondary schools for the anthelmintic treatment of parasites. Its structure is similar to that of the neurotransmitter glutamate, stimulating glutamate receptors and paralyzing the movement of nematodes and cestodes. It also has a neuroexcitatory effect on mammals, and large doses can destroy specific areas of the hippocampus. Melting point 251°C (decomposition). -14.1°. Soluble in water, insoluble in ether. pK a1 2.05, pK a2 4.30, pK a3 10.08.
