Sivelestat Chemische Eigenschaften,Einsatz,Produktion Methoden
Verwenden
Sivelestat is an inhibitor of neutrophil elastase that prevents neutrophil extracellular trap formation and rescues mice from endotoxic shock. The inhibition of neutropil elastase by Sivelestat is a promising therapeutic strategy to inhibit glial scar and promote functional recovery by upregulating angiopoietin-1 after spinal cord injury.
Allgemeine Beschreibung
A cell-permeable, potent, substrate-competitive, and highly specific inhibitor of neutrophil elastase (IC
50 = 19-49 nM using rat, rabbit, hamster, human, and mouse leukocyte elastase). Displays about 100-fold greater selectivity over pancreatic elastase (IC
50 = 5.6 μM) and is inactive against trypsin, thrombin, plasmin, kallikrein, chymotrypsin, and cathepsin G even at concentrations as high as 100 μM. Effectively suppresses human neutrophil elastase-induced lung hemorrhage and skin capillary permeability
in vivo. Also reported to inhibit mast cell Stat6-protease.
Biochem/physiol Actions
Sivelestat is a competitive human neutrophil elastase (HNE) inhibitor (IC50 = 44 nM, Ki = 0.2 μM). It also inhibits leukocyte elastase obtained from rabbit, rat, hamster and mouse (IC50 = 19 to 49 nM). However, it does not inhibit trypsin, thrombin, plasmin, plasma kallikrein, pancreas kallikrein, chymotrypsin and cathepsin G even at 100 μM. In in-vivo studies, it suppressed lung hemorrhage in hamster (ID50 = 82 μg/kg) by intratracheal administration and increase of skin capillary permeability in guinea pig (ID50 = 9.6 mg/kg) by intravenous administration, both of which were induced by human neutrophil elastase.
