Choose Selective MAO Inhibitors
|Description||Safinamide is an orally active, selective, reversible
The antiparkinson mechanism of safinamide is through reversible inhibition of selective MAO-B, thus reducing the degradation of dopamine. It inhibits glutamate release and dopamine reuptake in the brain. Safinamide also blocks sodium and calcium channels.
|In vivo||Safinamide is absorbed quickly, with a bioavailability of 95%, and a demonstrated time to maximum plasma concentration of 1.8-2.8 hours. It exhibits extensive extravascular distribution with a volume of distribution of approximately 165 L. Safinamide does not undergo significant first-pass metabolism and is mediated by amidase enzymes producing safinamide acid and other metabolites. Safinamide is mediated by cytochrome P450 (CYP) 3A4 isoenzymes. It is 88% to 90% plasma protein-bound and is primarily eliminated through the kidneys (approximately 76%) in the form of its metabolites, with an elimination half-life of 20 to 30 hours. About 1.5% of safinamide is found excreted in the feces. Safinamide exhibits linear pharmacokinetics after oral administration of 50 mg to 300 mg (three times the maximum recommended daily dose) with a steady state reached within five to six days.|

* 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.

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
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).
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.
