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

The transition of alveolar type II epithelial cells into fibroblasts has been reported to cause and/or aggravate pulmonary fibrosis (PF), which is characterized by fibroblast proliferation, an enhanced production and accumulation of ECM (extracellular matrix), alveolar wall damage and functional

Circulating neutrophil extracellular traps (NETs) resistant to t-PA have not been studied completely although NETs in thrombi may contribute to tissue plasminogen activator (t-PA) resistance. This research intended to elucidate whether circulating NETs are associated with t-PA resistance and the
Excess production of neutrophil elastase contributes to the pathogenesis of acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). However, the role of neutrophil elastase in the repair process following ALI/ARDS is not well understood. The objective of this

PA is an opportunistic pathogen that is commonly associated with severe infection in immunocompromised hosts. Siglec-9 binds with Sias by cis interaction on the neutrophil surface, thereby reducing immunological activity. However, neutrophils bind with pathogens through trans interactions of siglec-9
The pathology of neuromyelitis optica (NMO), in contrast to multiple sclerosis, comprises granulocyte infiltrates along extensive lengths of spinal cord, as well as optic nerve. Furthermore, IFN-β treatment worsens NMO. We recently found that experimental autoimmune encephalomyelitis (EAE) induced with
