Description

General description

An orally bioavailable, non-toxic pyrazolopyridinedione based compound that acts as a potent and reversible inhibitor of NOX1- and NOX4-containing NADPH oxidase activity (K_i = 160 and 165 nM, respectively, Amplex Red assay) and devoid of antioxidant properties. At higher concentrations, affects NOX2 (K_i = 1.53 uM). Blocks NOX-mediated ROS (reactive oxygen species) outburst in NOX isozyme expressing PMN cell membranes. Exhibits poor affinity towards xanthine oxidase, lipoxygenases-5/12, myeloperoxidase, MAO-B, iNOS and eNOS, several cytochrome P450 isozymes, PTP1B and a panel containing representative ion-channels and kinases at 10 µM. Functions as a selective scavenger of peroxynitrite over nitric oxide, superoxide radical anion and hydroxyl radical.

Please note that the molecular weight for this compound is batch-specific due to variable water content. Please refer to the vial label or the certificate of analysis for the batch-specific molecular weight. The molecular weight provided represents the baseline molecular weight without water.
