|Description||Niflumic acid is an inhibitor of cyclooxygenase-2 used for joint and muscular pain.|
Niflumic acid inhibits Ca2+-activated Cl- channels with inhibition constant of 17 mM. Niflumic acid also inhibits ICl(Ca) elicited by bath application of Ca2+ to oocytes permeabilized using the Ca2+ ionophore A23187, demonstrating that the inhibition of ICl(Ca) is due to a direct interaction with the Cl- channel, rather than by interference with Ca2+ entry through voltage-dependent Ca2+ channels.  Niflumic acid blocks Ca2+-activated non-selective cation channels in inside-out patches from the basolateral membrane of rat exocrine pancreatic cells with IC50 of 50 μM.  Niflumic acid dose-dependently and reversibly activates large conductance calcium-activated K+ (KCa) channels.  Niflumic acid produces a concentration-dependent inhibition of spontaneous transient inward current (STIC, calcium-activated chloride current) amplitude. Niflumic acid inhibits noradrenaline- and caffeine-evoked IO(Ca) with an ICM50 of 6.6 μM, i.e.is less potent against evoked currents compared to spontaneous currents. Niflumic acid voltage-dependently inhibits spontaneous transient inward current (STIC) amplitude with IC50 of 2.3 μM and 1.1 μM at -50 and +50 mV respectively.  Niflumic acid inhibits not only IL-13-induced goblet cell hyperplasia but also airway hyperresponsiveness and eosinophilic infiltration. Niflumic suppresses the eotaxin levels in bronchoalveolar lavage fluids and overexpression of the MUC5AC gene, a marker of goblet cell hyperplasia, in the lung after IL-13 instillation. Niflumic acid suppresses JAK2 activation, STAT6 activation, and eotaxin expression in epithelial cells.

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.
