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 (Na_v1.1) when used at a concentration of 100 µM.²Rufinamide inhibits Na_v1.1, but not Na_v1.2, Na_v1.3, and Na_v1.6, opening and increases the action potential threshold in primary rat hippocampal neurons. It is an inhibitor of carbonic anhydrase VA (CAVA; K_i= 343.8 nM) that is selective for CAVA over CAI and CAII (K_is = >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).
