GNE-9278 is a highly selective positive allosteric modulator of NMDAR that acts at the GluN1 transmembrane domain (TMD). GNE-9278 acts on activated NMDARs to increase peak current and agonist affinity
In Vitro
GNE-9278 (50 μM) slows deactivation with multiple agonists (D-Glu, L-Glu and L-CCG-IV) and enhances the potency of both Glu and Gly. GNE-9278 robustly potentiates GluN2A, 2B, 2C and 2D-containing NMDARs as measured by calcium influx assays from HEK cell lines with EC 50 s of 0.74, 3.07, 0.47, and 0.32 μM, respectively. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
