What is DIPHENYLENEIODONIUM CHLORIDE?
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.

The Uses of DIPHENYLENEIODONIUM CHLORIDE
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

What are the applications of Application
Diphenyleneiodonium chloride is an inhibitor of NOS2 (iNOS), NOS3 (eNOS), and neutrophil NADPH oxidase.
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.
