Description

General description

AMPA (α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid) activates excitatory postsynaptic currents (EPSC).

Application

(S)-AMPA has also been used to activate rostromedial tegmental nucleus (RMTg), to study aversive conditioning in relation with cocaine-induced avoidance behaviors in mice.

(S)-AMPA has been used to selectively eliminate the neural cochlear component of adult barn owls by destroying afferent synapses.

Biochem/physiol Actions

Active enantiomer of (RS)-AMPA zwitterion. Potent agonist at the AMPA subclass of ionotropic glutamate receptors.
