ML171 (2-Acetylphenothiazine;2-APT) is a potent and selective NADPH oxidase 1 (Nox1) inhibitor that blocks Nox1-dependent ROS generation, with an IC50 of 0.25 μM in HEK293-Nox1 confirmatory assay.
Nox1-dependent ROS generation has been shown to play a pivotal role in cell signaling, cell growth, angiogenesis, motility and blood pressure regulation. ML171 strongly blocks ROS generation in HT29 cells (IC50=0.129 μM) and only increasing over-expression of Nox1 can overcome the blockage of ROS generation caused by ML171 treatment in HEK293 cell system reconstituted with all the components required Nox1-dependent ROS generation. ML171 efficiently blocks ROS production measured by carboxy-H2-DCFDA staining as well as DPI used as a positive control. When ML171 is tested in HEK293-Nox1 reconstituted cell system, higher potency in blocking Nox1-dependent ROS generation is observed compared with the parental compound[1].

Cell experiment: | HT29 cells are cultured in 150 mm diameter plate and when 70-80% confluence is reached, cells are trypsinized, harvested in HBSS and counted. 4×104 cells are dispensed into individual wells in 30 μL final volume (384 well plates) by using a robotic liquid handler. Cells are treated for 60 min at 37°C with 50 nL of DPI, DMSO and library compounds (including ML171) which are automatically dispensed into individual wells from their respective assay plates. This will correspond to a final concentration of 10 μM DPI or library compounds (ML171), and 0.1% DMSO. 20 μL of a mixture containing 200 μM luminol plus 0.32 units of HRP (final concentration) is added. Luminescence is quantified using a 384-well plate luminometer. The data output consisting of the emission intensities for each well is imported into a spread-sheet program (such as Excel) for further processing. As designed, compounds that inhibit Nox1 activity will reduce cellular ROS production, leading to reduced probe-ROS interactions and reduced well luminescence. Compounds are considered ‘hits’ and further processed when light emission is blocked >75% 7 than DMSO wells (DMSO and DPI wells are set to 0% and 100% respectively). Compounds are tested in singlicate at a concentration of 10 μM[1]. |
