| | DIPHENYLENEIODONIUM CHLORIDE Usage And Synthesis |
| Description | Diphenyleneiodonium (DPI) is an inhibitor of NADPH oxidase (NOX; EC50 = 0.1 μM in HeLa cells). It also inhibits nitric oxide synthase (NOS; IC50 = 0.05 μM in isolated mouse peritoneal macrophages). DPI (10, 50, and 100 μM) induces the production of reactive oxygen species (ROS) in, and apoptosis of, human umbilical vein endothelial cells (HUVECs). It inhibits NETosis induced by phorbol 12-myristate 13-acetate (PMA; ) in isolated human neutrophils when used at a concentration of 10 μM. DPI (2 mg/kg) reduces tumor growth in HT-29 and LS 174T colon cancer mouse xenograft models. | | Chemical Properties | Crystalline Solid | | Uses | Diphenyleneiodonium Chloride binds strongly to flavoproteins and thus inhibits NO synthase, NADG reductase and NADPH oxidase.Diphenyleneiodonium Chloride solubility: 5 mg in 1.7 mL of H2O:DMSO 40:60; 10 mg in 1.1 mL H2O:DMSO 10:90 | | Uses | Binds strongly to flavoproteins and thus inhibits NO synthase, NADG reductase and NADPH oxidase.
Solubility: 5 mg in 1.7 mL of H2O:DMSO 40:60; 10 mg in 1.1 mL H2O:DMSO 10:90 | | Definition | ChEBI: An organic chloride salt having dibenziodolium as the counterion. | | 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. | | storage | Desiccate at -20°C | | References | 1) Stuehr?et al.?(1991),?Inhibition of macrophage and endothelial cell nitric oxide synthase by diphenyleneiodonium and its analogs; FASEB J.,?5?98
