Abstract
The (2S,3S,4S) isomer of alpha-(carboxycyclopropyl)glycine (L-CCG-I), a conformationally restricted glutamate analogue, caused a marked depolarization of motoneurons in the isolated rat spinal cord, which was almost insensitive to CPP and CNQX. Depolarizing responses to L-CCG-I were markedly decreased by reducing the temperature of the bathing fluid. Similar results were obtained in the case of trans-ACPD, which is a metabotropic glutamate receptor agonist, but the depolarizing action of L-CCG-I was more potent than that of trans-ACPD. In Xenopus oocytes injected with poly(A)+ mRNA extracted from the rat brain, L-CCG-I induced significant oscillatory chloride currents, suggesting that L-CCG-I is a potent agonist for metabotropic-type glutamate receptors.
