Product overview

  • Name
  • Short description
    GluN2C / GluN2D subunit selective NMDA receptor positive allosteric modulator
  • Biological description
    GluN2C / GluN2D subunit selective NMDA receptor positive allosteric modulator. Causes two-fold increase in receptor channel opening frequency (EC50 values are 2.7 and 2.8 µM for GluN2C and GluN2D respectively). Reduces associated behaviours in schizophrenia models and potentially enhances dopamine release in Parkinson's disease models.
