Description: GKT137831, also known as GTK831, is a novel and potent Nox4 inhibitor. GKT137831 reduced the increased leukocyte adherence to the vasculature, the pro-inflammatory phenotype of microglia and macroglia, the increased gene and protein expression of vascular endothelial growth factor, monocyte chemoattractant protein-1, and leukocyte adhesion molecules as well as vascular leakage. In all cultured cell types, GKT137831 reduced the hypoxia-induced increase in ROS levels and protein expression of various inflammatory mediators. GKT137831 may be potentially useful as a treatment for a variety of vision-threatening retinopathies.
