Novel inhibitor of NAD(P)H oxidase (Nox). In vascular smooth muscle cells VAS-2870 completely abolished PDGF-mediated NAD(P)H oxidase activation and ROS production (100% at 10µM). It inhibits PDGF-induced chemotaxis but not proliferation of VSMC. In mouse embryonic stem cells VAS-2870 blocked PDGF-BB-induced vasculogenesis. OxLDL-induced ROS formation in human endothelial cells was completely inhibited by VAS-2870 (100% at 5µM). VAS-2870 inhibits PMS-induced oxidative burst in HL-60 cells (IC₅₀=2µM).
