Product overview

  • Name
    PEAQX (NVP-AAM 077)
  • Short description
    Potent, competitive NMDA receptor antagonist
  • Biological description

    Potent and competitive NMDA receptor antagonist. Binds at the glutamate site.

    Shows some selectivity (~7-10-fold) for GluN1/2A (NR1/2A) over GluN1/2B (NR1/2B) subunit containing receptors (IC50 values are 31 and 215 nM at GluN1/2A and GluN1/2B respectively).

    Shows anticonvulsant activity. Active in vivo.
