Radiprodil

Radiprodil (RGH-896) is an orally active and selective NMDA NR2B receptors antagonist. It was a potential treatment of neuropathic pain associated with diabetic peripheral neuropathy (DPNP) . (In Vitro) :Preincubation with Radiprodil (10 nM) restores long-term potentiation (LTP) in the presence of Aβ1-42, 3NTyr10-Aβ and Aβ1-40, but not AβpE3.As for LTP, Radiprodil (10 nM) reverses the synaptic toxicity of 3NTyr-AβAβ1-40 and Aβ1-42 but not that AβpE3-42. (In Vivo) :Radiprodil could block NMDA currents in Mg2+ insensitive variants, with potencies similar to those obtained without Mg2+.Radiprodil's potency is higher at pH 7.0 than at pH 7.6, suggesting that radiprodil may retain its ability to block glutamate-induced NMDA currents even under acidic conditions that manifest under long term seizures.
