GKT-137831 | NADPH oxidase NOX1/4 inhibitor

GKT-137831 (1218942-37-0) is an NADPH oxidase, NOX1/4 inhibitor (Ki = 100-150 nM).1  Inhibits erastin-stimulated ROS production.2 Potentiates immunotherapy by overcoming cancer-associated fibroblast- mediated CD8+ T-cell exclusion.3 Reduces ROS production in LPS-stimulated platelets in a mouse model.4 Reduces subarachnoid hemorrhage-induced neuronal death.5 Potent inhibitor of experimental liver fibrosis in mouse models.6
