Biological Activity

Description Niflumic acid is an inhibitor of cyclooxygenase-2 used for joint and muscular pain.
Targets
COX-2 [1] GABA receptor [1]
In vitro

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. [1] 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. [2] Niflumic acid dose-dependently and reversibly activates large conductance calcium-activated K+ (KCa) channels. [3] 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. [4] 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. [5]

Bio Calculators

Molarity Calculator

Molarity Calculator

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).

Dilution Calculator

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 )

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.
