Flufenamic acids reversibly inhibits ICl(Ca) in Xenopus oocytes with IC50 of 28 mM, elicit in response to depolarizing voltage steps, in a dose-dependent manner, with no effect on the shape of the current-voltage curve. [1] Flufenamic acids blocks Ca2(+)-activated non-selective cation channels in inside-out patches from the basolateral membrane of rat exocrine pancreatic cells with IC50 of 10 μM. [2] Flufenamic acid binds with high affinity and negative cooperativity (pH 7.6) to wild-type (KD1=30 nM, KD2=255 nM), V30M (KD1=41 nM, KD2=320 nM) and L55P transthyretin (KD1=74 nM, KD2=682 nM), completely inhibiting amyloid fibril formation at a concentration of 10.8 μM, 3× the physiological concentration of transthyretin (3.6 μM), under conditions where transthyretin amyloid fibril formation is maximal (pH 4.4). [3] Flufenamic acid (viz 200 μM) produces a near complete collapse of the holding current at −50 mV, mirroring the effect of removal of extracellular Ca2+. Flufenamic acid inhibits recombinant human TRPM2 (hTRPM2) as well as currents activated by intracellular ADP-ribose in the CRI-G1 rat insulinoma cell line. Flufenamic acid antagonises ADP-ribose activated currents in the rat insulinoma cell line CRI-G1 in concentration- and pH-dependent kinetics manner. [4] Flufenamic acid reversibly inhibits (IC50 = 13.8 μM) DAPs and phasic firing with a similar time course in rat supraoptic neurones, but has no significant effects (P > 0.05) on membrane potential, spike threshold and input resistance, nor on the frequency and amplitude of spontaneous synaptic potentials.

Bio Calculators
Molarity Calculator
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).
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 )
* 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.
