CMPDA is a positive allosteric modulator of AMPA receptors with EC50s of 45.4 ± 4.2 nM/63.4 ± 5.6 nM for GluA2i/GluA2o receptor.IC50 value: 45.4 ± 4.2 nM/63.4 ± 5.6 nM(GluA2i/GluA2o) [1]Target: AMPAR modulatorCMPDA was nearly equipotent at modulating the two isoforms of GluA2 receptors, whereas CMPDB displayed a modest preference for the flip splice variant. Similar to CX614, CMPDA slowed the rate of deactivation of GluA2o receptors approximately 2-fold but had no effect on GluA2i receptor deactivation [1].
