Description

AMPA is the defining agonist for the AMPA subgroup of ionotropic glutamate receptors, which mediate excitatory neurotransmission. Because AMPA does not interfere with binding sites for kainic acid or NMDA , it can be used to distinguish AMPA receptor-specific activity that contributes to a neuronal response. (R,S)-AMPA contains an equal mixture of the active (S)-enantiomer and the inactive (R)-enantiomer.
