NPS 2390

Metabotropic glutamate receptors (mGluRs), mediate excitatory synaptic transmission in the central nervous system. Potent and selective antagonists of the type I mGluRs (mGluR1 and mGluR5) are of interest as novel therapeutics for the treatment of various CNS disorders, such as pain, epilepsy, and stroke. NPS 2390 is a first generation quinoxaline derivative that acts as a noncompetitive antagonist of mGluR1 and mGluR5 with IC₅₀ values equal to 5.2 and 82 nM, respectively). At concentrations up to 30 μM, NPS 2390 does not affect mGluR2 or mGluR8 or a standard collection of 37 additional receptors, ion channels, and enzymes. At a dose of 10 mg/kg, NPS 2390 displaced the specifically bound mGlu1R-selective antagonist, [³H]R214127, in rat cerebellum.

NPS 2390 is an inhibitor of CaSR (Calcium-sensing recpetor). NPS 2390 up-regulated anti-apoptotic protein Bcl-2 expression and down-regulated pro-apoptotic protein Bax.
