Purity & Quality Control
|Description||Apocynin 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).

* 1 mg/ml means slightly soluble or insoluble.
* 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.
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).
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.
