Flupirtine pre-incubated for 2 hours prevents cell death in rat cortical neurons induced by NMDA and gp120 of HIV-1.  Flupirtine is capable of protecting primary neurons against glutamate-induced cytotoxicity by reducing calcium ion concentrations at 1-10 mM.  Flupirtine pretreated for 2 hours preventsβ-amyloid-induced apoptosis in primary neuronal cells at concentrations of 1 or 5μg/mL.  Flupirtine at concentration of 10 μM markedly decreases nonreceptor-mediated necrotic cell death in PC 12 cultures treated with 10 mM L-glutamate, meanwhile, Flupirtine exerts anti-oxidative effects in PC 12 cultures.  Flupirtine-maleate at concentrations of 1 μM and 10 μM decreases TRAIL-mediated death of human living brain tissue culture.  Flupirtine activates inwardly rectifying potassium ion channels and thus stabilizes the resting membrane potential at a therapeutically relevant concentration. 
|In vivo||Pre-treatment with Flupirtine exerts a protective effect on hippocampal and striatal neuronal damage and on deficits in spatial learning in rats with cerebral ischemia.  Flupirtine administered centrally inhibits the nociceptive responses induced by chemical, thermal, mechanical and electrical stimuli in animal studies.  Flupirtine exerts muscle relaxant effects in rat. |

* 1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × 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).
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.
