Biochem/physiol Actions

GNE-9278 is a selective NMDAR, but not AMPAR, positive allosteric modulator (PAM fold enhancement Emax/EC50 = 5.5/0.74 μM/2A, 8.4/3.07 μM/2B,10.2/0.47 μM/2C, 7.9/0.32 μM/2D of gly EC50 (50 μM)-induced Ca++ influx in HEK293 co-expressing GluN1 & respective GluN2 subunit; Emax/EC50 = 4.6/3.2 μM/2A,12.4/15.7 μM/2B, 9.1/6.6 μM/2C, 14.9/6.7 μM/2D of 100 μM Glu-induced current in the presence of 50 μM gly using respective GluN1/GluN2 oocytes). GNE-9278 targets transmembrane domain (TMD) extracellular surface of agonist-bound NMDARs, stabilizing NMDARs in an activated state by slowing L-L-glu & gly off-rate.
Selective NMDAR, but not AMPAR, positive allosteric modulator (PAM) that targets TMD extracellular surface of ligand-bound NMDARs and slows L-Glu/Gly dissociation.
