VAS2870

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].
