Product Description

CGP 78608 hydrochloride is a potent and selective NMDA antagonist that acts through the glycine site (IC₅₀ = 5 nM). Displays > 500-fold selectivity over kainate and AMPA receptors (IC₅₀ values are 2.7 and 3 μM respectively). Also potentiates GluN1/GluN3A-mediated glycine currents (EC₅₀ = 26.3 nM). Anticonvulsant in vivo following systemic administration.
