Background:
Rufinamide-15N-d2is intended for use as an internal standard for the quantification of rufinamide by GC- or LC-MS. Rufinamide is an anticonvulsant.1It inhibits the activation of voltage-gated sodium channel 1.1 (Nav1.1) when used at a concentration of 100 µM.2Rufinamide inhibits Nav1.1, but not Nav1.2, Nav1.3, and Nav1.6, opening and increases the action potential threshold in primary rat hippocampal neurons. It is an inhibitor of carbonic anhydrase VA (CAVA; Ki= 343.8 nM) that is selective for CAVA over CAI and CAII (Kis = >10,000 nM for both).3Rufinamide (100 µM) prolongs the preictal phase and reduces seizure-like event frequency in anin vitromodel of epileptiform activity in rat hippocampal slices.4It inhibits seizures induced by pentylenetetrazole in a mouse model of epilepsy (ED50= 54 mg/kg, i.p.) and reduces kainic acid-induced neuronal cell death in the mouse hippocampal CA3 region when used at doses of 25, 50, and 100 mg/kg.5,6Formulations containing rufinamide have been used in the treatment of seizures associated with Lennox-Gastaut Syndrome (LGS).
