General description
A potent antagonist for NMDA receptors. Modestly higher selectivity for the NR2A than for the NR2B containing NMDA receptors (IC50 = 0.015 and 0.078 µM) but insufficient to discriminate between NR2A and NR2B-containing NMDA receptors. Widely used for researches in synaptic plastic, learning and memory, and epilepsy.

We have quantified the effects of the N-methyl-d-aspartate (NMDA) receptor antagonist (R)-[(S)-1-(4-bromo-phenyl)-ethylamino]-(2,3-dioxo-1,2,3,4-tetrahydroquinoxalin-5-yl)-methyl]-phosphonic acid (NVP-AAM077) at rat recombinant N-methyl-D-aspartate receptor (NR)1/NR2A and NR1/NR2B NMDA receptors expressed in Xenopus laevis oocytes. We observed no difference in the steady-state levels of inhibition produced

Neural cell adhesion molecule (NCAM) is the predominant carrier of the unusual glycan polysialic acid (PSA). Deficits in PSA and/or NCAM expression cause impairments in hippocampal long-term potentiation and depression (LTP and LTD) and are associated with schizophrenia and aging.

Sub-anesthetic doses of NMDA receptor antagonists suppress sleep and elicit continuous high-power gamma oscillations lasting for hours. This effect is subunit-specific, as it was also seen after preferential blockade of the NR2A but not of the NR2B subunit-containing receptors. The

Signaling at NMDA receptors (NMDARs) is known to be important for memory reconsolidation, but while most studies show that NMDAR antagonists prevent memory restabilization and produce amnesia, others have shown that GluN2B-selective NMDAR antagonists prevent memory destabilization, protecting the memory.
