Apocynin, an NADPH oxidase inhibitor, suppresses

NADPH oxidase is an enzyme that effectively reduces O 2 to superoxide (O 2-•), which can be used by the immune system to kill bacteria and fungi. Apocynin is an inhibitor of NADPH oxidase activity and thus is effective in preventing the production of the superoxide in human white blood cells or neutrophilic granulocytes In addition, the inhibitor of NADPH oxidase, apocynin, improves renal function in streptozotocin-induced diabetic rats, albeit over the relatively short period of 4 weeks (3). This agent's postulated mode of action is to impede the recruitment of the p47 phox and p67 phox subunits to the NADPH oxidase complex (14, 15) CONCLUSION: Activation of NADPH oxidase with translocation of p47phox to the membrane underlies the oxidative stress and limited NO generation, despite enhanced eNOS expression in a model of diabetic nephropathy. Apocynin prevents these changes and the associated proteinuria. PMID: 15840036 [Indexed for MEDLINE] Publication Types

Diphenyleneiodonium chloride (DPI) is an inhibitor of NADPH oxidase and also a potent, irreversible, and time-, temperature-dependent iNOS/eNOS inhibitor. Diphenyleneiodonium chloride (DPI) also functions as a TRPA1 activator and selectively inhibits intracellular reactive oxygen species (ROS) Benfotiamine (S-benzoyl thiamine O-monophosphate), an acyl derivative of thiamine, is a known inhibitor of NADPH oxidase and has been reported to prevent tissue damage in numerous experimental models [11,12]

Diphenyleneiodonium (DPI), an NADPH oxidase inhibitor, has been demonstrated to reduce ROS production and exert a protective role in numerous cell types (17 - 19). The present study investigated the protective effect of DPI in a renal tubular epithelium necroptosis model, which was established in our previous study (20) Gorin Y, Cavaglieri RC, Khazim K et al, Targeting NADPH oxidase with a novel dual Nox1/Nox4 inhibitor attenuates renal pathology in type 1 diabetes.

  6. Significance: Fibrosis is a stereotypic, multicellular tissue response to diverse types of injuries that fundamentally result from a failure of cell/tissue regeneration. This complex tissue remodeling response disrupts cellular/matrix composition and homeostatic cell-cell interactions, leading to loss of normal tissue architecture and progressive loss of organ structure/function
  7. The fact that the inhibitory effect of DPI on extracellular ROS production was reversible and could be easily washed off is in contrast to the generally accepted view that DPI is an irreversible inhibitor of flavin , a view that, in large part, is based on early biochemical work and the fact that radiolabeled DPI was found to bind one or more proteins of the NADPH oxidase (26, 27)

Apocynin is the most employed inhibitor of NADPH oxidase (NOX), a multienzymatic complex capable of catalyzing the one-electron reduction of molecular oxygen to the superoxide anion. Despite controversies about its selectivity, apocynin has been used as one of the most promising drugs in experimental models of inflammatory and neurodegenerative diseases A cell-permeable, anti-inflammatory phenolic compound that acts as a potent and selective inhibitor of NADPH oxidase.

In this study we analyzed the microRNAs profile targeting NOX2 and NOX4 genes and its response to NOX2/4 inhibitor VAS2870 to understand the mechanisms of this protective effect

Figure 4B shows that S17834 caused a concentration-dependent decrease in NADPH oxidase activity, with significant decreases observed at 25 and 50 μmol/L. Diphenyleneiodonium (10 μmol/L), a nonspecific inhibitor of flavoproteins including NADPH oxidase, xanthine oxidase, and NO synthase, reduced activity ≈80% to 0.093±0.041 nmol · min −1 · mg −1, a level similar to that reached with. The pharmacological suppression of this insulin-stimulated ROS elevation, either by antioxidant or by an NADPH oxidase inhibitor, abolished the anorexigenic effect of insulin. Finally, in fasted and short-term high-fat diet-fed mice, insulin did not promote elevation of ROS level and food intake inhibition, likely because of an increase in hypothalamic diet-induced antioxidant defense systems We recently reported that subpicomolar concentrations of DPI have great specificity to potently inhibit NADPH oxidase-generated superoxide without affecting the activities of other cytochrome-containing enzymes, such as inducible nitric oxide synthase, xanthine oxidase, cytochrome P450 reductase, thioredoxin reductase, and complex I, in cultured microglia (Wang et al., 2014a)

NADPH oxidases are pharmacological targets for the treatment of inflammation-based diseases.

NADPH oxidase inhibition targets deleterious microglial activation. Increasing evidence points to NADPH oxidase (also called phagocytic oxidase (PHOX)) as a critical mechanism of microglia-mediated neuron damage. Traditional anti-inflammatory approaches focus on specific downstream targets,. Therefore, we set out to investigate the effect of reducing NADPH oxidase-derived superoxide on arterial remodelling in our collar model by applying an NADPH oxidase inhibitor to the adventitia. One of the advantages of the collar model is that it allows the effects of drugs to be examined locally, without the complication of systemic actions In a previous study, the specific NOX1/2/4 inhibitor Ewha-18278 was confirmed as a possible treatment for osteoporosis both in vitro and in vivo.

Various experimental models strongly support the hypothesis that airway inflammation can be caused by oxidative stress. Inflammatory airway diseases like asthma and COPD are characterized by higher levels of ROS and inflammatory cytokines. One of the sources of ROS is NADPH oxidase. Therefore, the aim of the study was to investigate influence of NADPH oxidase inhibition on the expression of IL. Immunoblots of membranes using a specific p47 phox antibody showed that p47 phox translocation was not inhibited by celastrol (1 and 5 µM), whereas it was inhibited by staurosporine (200 nM), an inhibitor of PKC (Figure 3C) previously demonstrated to block phosphorylation-dependent translocation of p47 phox (Nauseef et al., 1991), a prerequisite for oxidase assembly and activity (Heyworth et.
