CX516 is a so-called ampakine, a molecule that potentiates currents mediated by AMPA-type glutamate receptors. As a class, these drugs enhance AMPA-receptor activity by slowing deactivation and attenuating desensitization of AMPA receptor currents, thus increasing synaptic responses and enhancing long-term potentiation (reviewed in Arai and Kessler, 2007).
