    Product Description

    GW 311616A is an inhibitor of neutrophil elastase (IC50 = 100 nM).1 It is selective for neutrophil elastase (IC50 = 22 nM for the human enzyme) over trypsin, cathepsin G, and plasmin (IC50s = >100 µM for all), as well as chymotrypsin and tissue plasminogen activator (IC50s = >3 µM for both), in cell-free assays. GW 311616A (20 µM) inhibits the formation of neutrophil extracellular traps (NETs) induced by phorbol 12-myristate 13-acetate (PMA; Item No. 10008014) in isolated human neutrophils.2 It inhibits intraneutrophil elastase activity in isolated dog blood six hours after administration of a 0.22 mg/kg dose.3 GW 311616A also inhibits neutrophil elastase in the liver in a mouse model of liver ischemia-reperfusion injury when administered at a dose of 2 mg/kg.4

    WARNING This product is not for human or veterinary use.
