E8008 QNZ46 QNZ46 is a NR2C/NR2D-selective NMDA receptor non-competitive antagonist (IC50 values are 3, 6, 229, and >300, >300 μM for NR2D, NR2C, NR2A, NR2B, and GluR1, respectively). IC50 value: 3 μM (for NR2D), 6 μM (for NR2C), 229 μM (for NR2D NR2A)Target: NR2D, NR2C, NR2Ain vitro: QNZ46 is a noncompetitive inhibitor of GluN2C/D containing NMDA receptors. KD and IC50 values for binding and inhibition of GluN1/Glun2D receptors by QNZ46 are 4.9 and 3.9 μM, respectively. QNZ46 does not compete for binding of glutamate or glycine, but QNZ46 receptor binding requires the binding of glutamate to the GluN2 subunit.
E7521 MDL-29951 MDL-29951 is a novel glycine antagonist of NMDA receptor activation, with Ki of 0.14 μM for [3H]glycine binding in vitro and in vivo.
