Description: Potent NMDA antagonist; more active enantiomer of (RS)-CPP
Chemical Name: 3-((R)-2-Carboxypiperazin-4-yl)-propyl-1-phosphonic acid
Biological Activity for (R)-CPP
(R)-CPP is a highly potent NMDA antagonist; more active isomer. Shows some selectivity for GluN2A (formally NR2A) containing receptors (Ki values are 0.041, 0.27, 0.63 and 1.99 μM for inhibition of GluN2A-, GluN2B-, GluN2C- and GluN2D-containing recombinant NMDA receptors respectively).
Racemate also available.
Please refer to IUPHAR Guide to Pharmacology for the most recent naming conventions.
