Diphenyleneiodonium chloride is an irreversible inhibitor of nitric oxide synthases, iNOS and eNOS, NADPH cytochrome P450 oxidoreductase and inhibits preferentially the plasma membrane NADH oxidase (NOX) activity. Diphenyleneiodonium chloride exhibits potent antimicrobial activity against non-tuberculous mycobacteria and possesses a potentially new mechanism of action. Besides, experiments on diabetic animal models have shown, that diphenyleneiodonium mitigates sciatic nerve damage by attenuating oxidative stress.

Sample Use Guides

Diabetic Neuropathy Rat Model: diphenyleneiodonium (DPI) chloride (1 mg/kg) was injected subcutaneously 24 hours and 30 minutes before the sciatic block
Route of Administration: Other
Diphenyleneiodonium chloride (DPI) effectively inhibited NO production (IC50=0.03+/-0.004 microM), as evaluated by the method of Griess. Nuclear factor-kappa B (NF-kappaB) activation, as evaluated by electrophoretic mobility shift assay, was inhibited by DPI (1-10 microM) in a dose-dependent manner. IL-1-induced ROS production, as evaluated by measurement of dichlorofluorescein fluorescence, was inhibited by DPI at concentrations that also prevented NF-kappaB activation and iNOS expression.
