|Description||Apocynin (Acetovanillone) is a selective NADPH-oxidase inhibitor with IC50 of 10 μM.|
Apocynin is a naturally occurring methoxy-substituted catechol used as an inhibitor of NADPH-oxidase. Apocynin prevents serine phosphorylation of p47phox and blocks its association with gp91phox, thus blunting NADPH oxidase activation.  Apocynin can decrease the production of superoxide (O(2)(-)) from activated neutrophils and macrophages. Apocynin, after metabolic conversion, inhibits the assembly of NADPH-oxidase that is responsible for reactive oxygen species (ROS) production. 
|In vivo||Apocynin has anti-inflammatory activity in a variety of cell and animal models of inflammation. Apocynin attenuates the TNF-α and IL-1β production and iNOS expression in the lung of carrageenan-treated mice.  Apocynin exerts beneficial effects in a mice model of spinal cord injury. Apocynin reduces (1) the degree of spinal cord damage, (2) neutrophils infiltration, (3) ICAM-1 and P-selectin expression, (4) PAR and nitrotyrosine formation, (5) IκB-α degradation, (6) NF-κB activation, (7) pro-inflammatory cytokines production (TNF-α and IL-1β), (8) apoptosis (TUNEL staining, FAS ligand expression, Bax and Bcl-2 expression) and (9) MAPK activation (P-38 and phospho-JNK).

|In vitro||DMSO||33 mg/mL (198.59 mM)|
|Ethanol||33 mg/mL (198.59 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
2% DMSO+30% PEG 300+ddH2O
For best results, use promptly after mixing.
* 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.
