Sivelestat (EI546) sodium is a competitive inhibitor of human neutrophil elastase , with an IC 50 of 44 nM and a K i 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] .
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 IC
50
values of 44 nM, 36 nM, 19 nM, 37 nM and 49 nM for human, rabbit, rat, hamster and mouse neutrophil elastase, respectively
[1]

Sivelestat (ONO-5046, 0.021-2.1 mg/kg, intratracheally) suppresses lung hemorrhage in hamster (ID
50
= 82 pg/kg) by intratracheal administration and increase of skin capillary permeability in guinea pig (ID
50
= 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

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. |
