2-(2-Chlorophenyl)-4-(3-(diMethylaMino)phenyl)-5-Methyl-1H-pyrazolo[4,3-c]pyridine-3,6(2H,5H)-dione

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

2-(2-Chlorophenyl)-4-(3-(dimethylamino)phenyl)-5-methyl-1H-pyrazolo[4,3-c]pyridine-3,6(2H,5H)-dione is a potential drug candidate, which is used in the preparation of pyrazolopyridine derivative as NADPH oxidase inhibitors.
