|Description||Amlexanox (AA-673, CHX-3673) is an anti-inflammatory antiallergic immunomodulator and also an inhibitor of the protein kinases TBK1 and IKK-ε.|
Dose-response relationship of amlexanox inhibition of IKK-ɛ and TBK1 activity as determined by MBP phosphorylation showing an IC50 of approximately 1-2 μM. Amlexanox also blocks the activity of TBK1 at approximately the same concentrations but has no effect on IKK-α or IKK-β and at these concentrations do not block any other kinases from a broad panel representing most kinase families. Inhibition of IKK-ɛ or TBK1 by amlexanox is competitive for its substrate ATP, indicating that it interacts with the enzymes in the ATP-binding site. Amlexanox increases the phosphorylation of TBK1 at Ser172 in 3T3-L1 adipocytes and blocks polyinosinic:polycytidylic acid (poly I:C)-stimulated phosphorylation of interferon responsive factor-3 (IRF3), a presumed substrate of IKK-ɛ and TBK1.
|In vivo||Treatment of obese mice with amlexanox elevates energy expenditure through increased thermogenesis, producing weight loss, improves insulin sensitivity and decreases steatosis.|
|In vitro||DMSO||59 mg/mL (197.79 mM)|
* 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.
