Biological Data

Biological description

Selective antagonist for GluN2D subunit containing NMDA receptors. Binds competitively at the glutamate site.

Displays ~10- fold selectivity for GluN2D-containing receptors over GluN2B (NR2B) or GluN2A (NR2A) containing receptors (Ki values are 1.19, 7.99 and 11.53 at GluN1/GluN2D, GluN1/GluN2B and GluN1/GluN2A containing receptors respectively).

Inhibits synaptic NMDAR response.
