生物活性

Sivelestat (EI546) sodium is a competitive inhibitor of human neutrophil elastase, with an IC50 of 44 nM and a Ki of 200 nM. Sivelestat (EI546) sodium has the potential for the study of acute lung injury/acute respiratory distress syndrome or disseminated intravascular coagulation in COVID-19[1][2][3][4].

体外研究
(In Vitro)

Sivelestat (ONO-5046) does not inhibit trypsin, thrombin, plasmin, plasma kallikrein, pancreas kallikrein, chymotrypsin and cathepsin G even at 100 μM[1].
Sivelestat (ONO-5046) exhibits IC50 values of 44 nM, 36 nM, 19 nM, 37 nM and 49 nM for human, rabbit, rat, hamster and mouse neutrophil elastase, respectively[1].

体内研究
(In Vivo)

Sivelestat (ONO-5046, 0.021-2.1 mg/kg, intratracheally) suppresses lung hemorrhage in hamster (ID50 = 82 pg/kg) by intratracheal administration and increase of skin capillary permeability in guinea pig (ID50 = 9.6 mg/kg) by intravenous administration, both of which are induced by human neutrophil elastase[1].
Sivelestat (10 mg/kg, infusion via the tail vein) ameliorates lung injury after hemorrhagic shock in rats[2].
Sivelestat (15, 60 mg/kg, ip) prevents ischemia–reperfusion injury in the rat bladder[3].

Animal Model: Male Golden hamsters, weighing 90 to 110 g[1].
Dosage: 0.021-2.1 mg/kg.
Administration: Intratracheally five min before HNE injection.
Result: Significantly and dosedependently suppressed the lung hemorrhage.
Animal Model: Male Sprague-Dawley rats weighing 350-400 g[2].
Dosage: 10 mg/kg.
Administration: Continuous infusion via the tail vein at 10 mg/kg/h for 60 min during the resuscitation phase.
Result: Greatly suppressed lung injury, as revealed by the reduced histological damage.
Significantly ameliorated HSR-induced lung injury.
Markedly decreased the levels of TNF-α and iNOS gene.
Animal Model: Male Sprague Dawley rats, 8 weeks old and weighing 250-320 g[3].
Dosage: 15 mg/kg or 60 mg/kg.
Administration: IP.
Result: Decreased the blood flow in the bladder during reperfusion phase compared to the IR group.
