VAS2870 is a NADPH oxidase (NOX) inhibitor.

IC50 & Target

Target: NADPH oxidase[1]

In Vitro

VAS2870 is effective to suppress PDGF-BB-dependent activation of NADPH oxidase and subsequent production of intracellular ROS. Furthermore, VAS2870 suppresses PDGF-BB-dependent chemotaxis, but not DNA synthesis. Preincubation with VAS2870 (10 and 20 μM) completely abolishes PDGF-mediated NADPH oxidase activation and ROS production. Preincubation with VAS2870 (0.1-20 μM) does not affect PDGF-induced cell cycle progression. However, it abolishes PDGF-dependent chemotaxis of VSMC in a concentration-dependent manner (100% inhibition at 10 μM)[1]. VAS2870 inhibits dose-dependently autocrine increase of cell number in FaO rat hepatoma cells, and almost completely blocked ROS production and thymidine incorporation when used at 25 mM. VAS2870 blocks serum-dependent cell growth of FaO rat hepatoma cells. VAS2870 inhibits proliferation of different human hepatocellular carcinoma (HCC) cell lines. VAS2870 pretreatment enhances TGF-b-mediated apoptosis of FaO rat hepatoma cells[2].

Kinase Assay

NADPH oxidase activity is measured by lucigenin-enhanced chemiluminescence in a 50 mM phosphate buffer (buffer A), pH 7.0, containing 1 mM EGTA, protease inhibitors, 150 mM sucrose, 5 μM lucigenin, and 250 μM NADPH as substrate. Quiescent cells are starved by serum deprivation for 24 h and treated as indicated, ished twice with ice-cold phosphate buffered saline (PBS), pH 7.4, and harvested. After low spin centrifugation, the pellet is re-suspended in ice-cold buffer A, lacking lucigenin and substrate. Then, the cells are lysed and total protein concentration is determined using a Bradford assay and adjusted to 1 mg/mL. 100 μL aliquots of the protein sample are measured over 6 min in quadruplicates using NADPH (100 μM) as substrate in a scintillation counter. Data are collected at 2 min intervals in order to measure relative changes in NADPH oxidase activity[1].

Cell Assay

To test autocrine growth, cells are serum deprived at 40% confluence and, when indicated, the NADPH oxidase inhibitors Apocynin (300 mM) or VAS2870 are added 30 min before serum deprivation and maintained along the experiment. For TGF-b experiments, cells at 70% confluence are serum deprived for 16 h and treated with 2 ng/mL TGF-β in the presence or absence of the EGFR inhibitor AG1478 (20 mM) or VAS2870 (25 mM), which are added 30 min prior to TGF-β[2].
