Abstract
L-GLUTAMIC acid is probably an excitatory transmitter of major significance in the mammalian central nervous system1. The L-glutamic acid molecule is relatively flexible, and in an attempt to gain some insight into its possible shape(s) during activation of receptors associated with excitation of central neurones, a study was made of four conformationally restricted analogues: (±)-cis-1-aminocyclohexane-1,3-dicarboxylic acid (‘cyclo-glutamic’ acid), ibotenic acid, kainic acid and its dihydro derivative.
