Manufacturer:  MilliporeSigma™ 49200210MG

Catalog No. 49-200-210MG

Description

A highly selective, cell-permeable, and reversible 2-acetylphenothiazine that is shown to inhibit NADPH Oxidase-1 (Nox1) (IC₅₀ = 0.129µM, and 0.25µM) in human HT29 and HEK293 cell-based assays, respectively. Unlike most other currently used Nox inhibitors, it only has marginal activity on other cellular ROS-producing enzymes and receptors including the other Nox isoforms (IC₅₀ = 5µM, 3µM and 5µM for Nox2, Nox3, and Nox4, respectively) and xanthine oxidase, XO, (IC₅₀ = 5.5µM) in HEK293 cell-based assays. It is also shown to block Nox1-dependent ROS generation in HEK293 cultures dose-dependently at concentrations up to ~ 100nM; however, its inhibitory effect is reversed through over-expression of Nox1, thereby suggesting that this compound is highly selective for Nox1, with little effect against Nox2-dependent ROS generation (IC₅₀ > 10µM). Qualitatively, it displays an inhibitory effect against SrcYF-induced ECM-degrading invadopodia formation in DLD1 Human Colon Cancer Cells.
