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.

Mechanism of Action

Targets/IC50/Ki
NADPH-oxidase [1]
(Cell-free assay)
10 μM
In vitro
Apocynin is a naturally occurring methoxy-substituted catechol used as an inhibitor of NADPH-oxidase. This compound prevents serine phosphorylation of p47phox and blocks its association with gp91phox, thus blunting NADPH oxidase activation. [2] It can decrease the production of superoxide (O(2)(-)) from activated neutrophils and macrophages. This chemical, after metabolic conversion, inhibits the assembly of NADPH-oxidase that is responsible for reactive oxygen species (ROS) production. [3]
In vivo
Apocynin has anti-inflammatory activity in a variety of cell and animal models of inflammation. This compound attenuates the TNF-α and IL-1β production and iNOS expression in the lung of carrageenan-treated mice. [4] It exerts beneficial effects in a mice model of spinal cord injury. This chemical 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).
