    Scientific background

    Glutamate is the main excitatory neurotransmitter in the CNS. It is also involved in a variety of pathological conditions including epilepsy. Glutamate binds to a number of different receptor types such as the AMPA, kainate and NMDA receptors that relay its excitatory activity.

    (RS)-AMPA is a synthetic AMPA receptor agonist. It has an effective concentration of 0.1-100 µM. RS-AMPA selectively binds to AMPA receptors over the other types of glutamate receptors. RS-AMPA was found to elicit feeding behavior in a rat model while RS-AMPA’s enantiomer did not produce similar results1.
