rp 54274

Riluzole (RP-54274) is a glutamate antagonist (RECEPTORS, GLUTAMATE) used as an anticonvulsant (ANTICONVULSANTS) and to prolong the survival of patients with AMYOTROPHIC LATERAL SCLEROSIS.

Riluzole-13C,15N2 is intended for use as an internal standard for the quantification of riluzole by GC- or LC-MS. Riluzole is a benzothiazole derivative with anti-excitotoxic effects that acts by blocking the presynaptic release of glutamate, indirectly antagonizing glutamate receptors, and inactivating neuronal voltage-gated Na+ channels (ED50 = 2.3 μM). Riluzole suppresses glutamate-induced seizures in rats at an ED50 value of 3.2 mg/kg and displays neuroprotective effects in hypoxic animals at an ED50 value of 4 mg/kg. Formulations containing riluzole have been explored as therapeutics for slowing disease progression of amyotrophic lateral sclerosis.

Riluzole hydrochloride (PK 26124 hydrochloride) is an anticonvulsant compound belonging to the family of sodium channel blockers that inhibits GABA uptake.Riluzole hydrochloride is a sodium-glutamate antagonist with anticancer and neuroprotective activity and can be used to study amyotrophic lateral sclerosis and neurological disorders.
