Application

Ro 25-6981 hydrochloride hydrate has been used:
  • as NR2B antagonist for microinjecting rats to study the contribution of NR2B- and NR2A-containing N-methyl-D-aspartate receptors (NMDARs) to the formation of trace and contextual memory in prefrontal cortex (PL)
  • as NR2B antagonist to study the effect of the protein expression of hypoxic-ischemic injury NMDAR subunits 2A and 2B in the SVZ of neonatal rats
  • to induce deleterious effects upon memory consolidation and long-term potentiation (LTP) generation in the hippocampus

Biochem/physiol Actions

Potent and selective antagonist of NMDA glutamate receptors containing the NR2B subunit.

The interaction of Ro 25-6981 with N-methyl-D-aspartate (NMDA) receptors was characterized by a variety of different tests in vitro. Ro 25-6981 inhibited 3H-MK-801 binding to rat forebrain membranes in a biphasic manner with IC50 values of 0.003 microM and 149

The mechanisms underlying type-2 diabetic neuropathic pain (DNP) are unclear. This study investigates the coupling of postsynaptic density-95 (PSD-95) to N-methyl-D-aspartate receptor subunit 2B (GluN2B), and the subsequent phosphorylation of GluN2B (Tyr1472-GluN2B) in the spinal cord in a rat model
