Biological Activity

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

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 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.
