Sivelestat sodium tetrahydrate (Synonyms: LY544349, ONO-5046) |
| Catalog No.GC16898 |
Sivelestat (EI546) sodium tétrahydraté est un inhibiteur compétitif de l'élastase des neutrophiles humains, avec une IC50 de 44 nM et un Ki de 200 nM. Le tétrahydrate de sodium Sivelestat (EI546) a le potentiel d'étudier les lésions pulmonaires aiguës/le syndrome de détresse respiratoire aiguë ou la coagulation intravasculaire disséminée dans le COVID-19.

Sivelestat sodium tetrahydrate is a competitive inhibitor of human neutrophil elastase(IC50 = 44 nM; Ki=200 nM); also inhibited leukocyte elastase obtained from rabbit, rat, hamster and mouse.IC50 value: 44 nM [1]Target: neutrophil elastaseONO-5046 did not inhibit trypsin, thrombin, plasmin, plasma kallikrein, pancreas kallikrein, chymotrypsin and cathepsin G even at 100 microM. In in vivo studies, ONO-5046 suppressed lung hemorrhage in hamster (ID50 = 82 micrograms/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 [1]. Sivelestat sodium hydrate is an anti-neutrophil elastase inhibitor and may be one of the treatment options for acute respiratory failure due to pneumocystis pneumonia in AIDS patients [2].
