TCN 213 acts as a selective and potent NMDA (methyl-d-aspartate) receptor antagonist. This compound displays a high selectivity for GluN1/GluN2A-containing NMDAR receptors over GluN1GluN1/GluN2B containing NMDAR receptors. The degree of its antagonism is dependent on the concentration of the GluN1-site co-agonist, glycine or d-serine, and is independent of the glutamate concentration1. Relatively high concentrations of TCN 213 are required to achieve substantial block of GluN2A NMDAR-mediated responses.
NMDA receptors are heterotetrameric channels formed by the assembly of two obligatory GluN1 and two GluN2/GluN3 subunits. NMDAR plays an important role in a variety of cellular processes and brain functions such as, synaptic plasticity, addiction and stroke. NMDA receptors mediate physiological functions such as learning and memory formation. They play a role in glutamate excitotoxicity and are involved in many neurodegenerative conditions including Alzheimer’s disease2.
TCN 213 (#T-215) is a highly pure, synthetic, and biologically active compound.
