生物活性:
Sivelestat (EI546) is a competitive inhibitor of human neutrophil elastase, with an IC50 of 44 nM and a Ki of 200 nM. Sivelestat (EI546) has the potential for the study of acute lung injury/acute respiratory distress syndrome or disseminated intravascular coagulation in COVID-19.
体内研究:
Sivelestat (ONO-5046,0.021-2.1 mg/kg,气管内) 通过气管内给药抑制仓鼠肺出血 (ID50=82 pg/kg) 并增加豚鼠皮肤毛细血管通透性 (ID50=9.6 mg/kg) 通过静脉给药,均由人中性粒细胞弹性蛋白酶诱导。Sivelestat (10 mg/kg,输注通过尾静脉) 改善大鼠失血性休克后的肺损伤。Sivelestat (15、60 mg/kg,腹腔注射) 可预防大鼠膀胱的缺血再灌注损伤。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.
体外研究:
Sivelestat (ONO-5046) 不抑制胰蛋白酶、凝血酶、纤溶酶、血浆激肽释放酶、胰腺激肽释放酶、胰凝乳蛋白酶和组织蛋白酶 G,即使浓度为 100 μM。 Sivelestat (ONO-5046) 对人、兔、大鼠、仓鼠和小鼠中性粒细胞弹性蛋白酶的 IC50 值分别为 44 nM、36 nM、19 nM、37 nM 和 49 nM。
