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.

AMPA-type ionotropic glutamate receptors (iGluRs) represent the major excitatory neurotransmitter receptor in the developing and adult vertebrate CNS. They are crucial for the normal hardwiring of glutamatergic circuits but also fine tune synaptic strength by cycling into and out of

The strength of synaptic communication at central synapses depends on the number of ionotropic glutamate receptors, particularly the class gated by the agonist AMPA (AMPARs).

The syntheses of (RS)-alpha-amino-3-hydroxy-5-tert-butyl-4-isoxazolepropionic acid (9, ATPA), (alpha-RS, beta-RS)-alpha-amino-beta-methyl-3-hydroxy-5-isoxazolepropionic acid (8), (RS)-alpha-amino-3-hydroxy-5-isoxazolebutyric acid (15a), and (RS)-alpha-amino-3-hydroxy-5-isoxazolevaleric acid (15b) are described. The compounds were tested in vitro together with (RS)-alpha-amino-3-hydroxy-5-(bromomethyl)-4-isoxazolepropionic acid (ABPA) as inhibitors of the binding of radioactive-labeled (RS)-alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid
