Spatial memory performance. a Latency to find the hidden platform. LPS-infused controls and Aged controls were impaired (*p<0.001) compared to young aCSF-infused rats. The performance of Aged rats improved across days only when treated with Ril (†t=0.035). b Distance. LPS controls swam a greater distance than aCSF controls and Aged controls (*p≤0.036). c Swim Speed. Aged rats swam the most slowly (*p≤0.001). d Thigmotaxis. Aged controls spent the greatest percentage of time within the pool perimeter (*p<0.001).

The effect of intrathecal administration of riluzole on changes of tail flick latency in EA-treated rats (Mean ± SD, %, n = 6). EA was given once per day for eight consecutive days. Riluzole or vehicle was given once daily 30 min prior to EA. The significance of differences was calculated by a one-way ANOVA. EA + V: EA plus vehicle; EA + R20: EA plus 20 μg riluzole; EA + R10: EA plus 10 μg riluzole; EA + R5: EA plus 5 μg riluzole; R20, 20 μg riluzole. The values with different letters (a–d) at the same day differ (p < 0.05).

| In vitro |
Riluzole inhibits the release of glutamic acid from cultured neurons, and from brain slices. These effects may be partly due to inactivation of voltage-dependent sodium channels on glutamatergic nerve terminals, as well as activation of a G-protein-dependent signal transduction process. Electrophysiologic experiments performed on isolated excitatory amino acid receptors expressed in the Xenopus oocyte have revealed that Riluzole inhibits currents evoked by N-methyl-D-aspartate (NMDA) (IC50 = 18 μM) and kainic acid (IC50 = 167 μM). Riluzole has been shown to stabilize inactivated sodium channels in frog sciatic nerve, in rat cerebellar granule cells, and on recombinant rat sodium channels expressed in Xenopus oocytes (Ki = 0.2 μM). Riluzole also blocks some of the postsynaptic effects of glutamic acid by noncompetitive blockade of NMDA receptors. Tiluzole protects cultured neurons from anoxic damage, from the toxic effects of glutamic-acid-uptake inhibitors, and from the toxic factor in the CSF of patients with amyotrophic lateral sclerosis.

| In vivo | Riluzole can easily cross the blood-brain barrier. Riluzole has neuroprotective, anticonvulsant, and sedative properties in vivo. In a rodent model of transient global cerebral ischemia, a complete suppression of the ischemia-evoked surge in glutamic acid release has been observed by Riluzole treatment (8 mg/kg i.p.). [1] |

Bio Calculators
Molarity Calculator
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Dilution Calculator
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
