Beschreibung

Anwendung

Sivelestat sodium salt hydrate may be used to inhibit human neutrophil elastase-mediated cell signaling.

Biochem./physiol. Wirkung

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.
