title: Phosphonate analogues of carboxylic acids as aminoacid antagonists on rat cortical neurones.
abstract: Phosphonate analogues of carboxylic acids have been tested as antagonists of excitatory aminoacids in rat cerebral cortex. (+/-)--2-Amino-7-phosphono-heptanoic acid and the (-)-D-isomer of the pentanoate derivative were more potent and selective antagonists of N-methyl-D-aspartate (NMDA) than compounds tested previously. The results support the view that a distinct population of receptors exists which are preferentially activated by NMDA.
