Application

Ro 25-6981 maleate salt has been used as a selective N-methyl D-aspartate receptor subtype 2B (NR2B) blocker to study its effects on patch-clamp recordings of N-methyl D-aspartate receptor subtype 2A (NR2A)-containing N-methyl D-aspartate receptor (NMDAR) excitatory postsynaptic currents (EPSCs).

Biochem/physiol Actions

Ro 25-6981 maleate salt is a potent and selective antagonist of NMDA glutamate receptors containing the NR2B subunit with IC50 values of .009 μM for NR2B vs. 52 μM for NR2A subunits. Ro 25-6981 has been shown to have neuroprotectant effects and to reduce inflammatory and neuropathic pain in rodent models.
