生物活性

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

性状

Solid

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.
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.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

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.
Sivelestat (10 mg/kg, infusion via the tail vein) ameliorates lung injury after hemorrhagic shock in rats.
Sivelestat (15, 60 mg/kg, ip) prevents ischemia–reperfusion injury in the rat bladder.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:	Male Golden hamsters, weighing 90 to 110 g.
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.
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.
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.
