Application

Diphenyleneiodonium chloride has been used as an NOX inhibitor:
  • to study its effects on the reactive oxygen species (ROS) levels and also its inhibitory effects on killing tumor cells by neutrophils isolated from clinical malignant pleural effusion (MPE) samples
  • as a nicotinamide adenine dinucleotide phosphate (NADPH) oxidase inhibitor to confirm the variation in inflammation was secondary to overproduction of reactive oxygen species (ROS) in cells treated with doxorubicin (DOX) + flagellin (FL)
  • as an NADPH oxidase (NOX) inhibitor to study its effects on palmitate (PA)-induced sphere-forming ability of HepG2 (hepatocellular carcinoma) cells

Biochem/physiol Actions

A potent and reversible inhibitor of nitric oxide synthetase from macrophages and endothelial cells. Also inhibits other flavoenzymes such as neutrophil NADPH oxidase.
A potent reversible nitric oxide synthetase inhibitor from macrophages and endothelial cells.
Diphenyleneiodonium (DPI) can affect mitochondrial function. DPI can block neuron degeneration in Parkinson′s disease. It provides neuroprotection following focal cerebral ischemia. DPI can induce a chemo-quiescence phenotype in cancer stem-like cells, effectively inhibiting their proliferation.

Adipose-derived stem cells (ASCs) show great potentials in applications such as therapeutic angiogenesis, regenerative medicine and tissue engineering. Pharmacological preconditioning of stem cells to boost the release of cytoprotective factors may represent an effective way to enhance their therapeutic efficacy.
