实验参考方法
In Vitro

In vitro activity: Sivelestat suppresses both adhesion and transmigration of neutrophils to the endothelium


Kinase Assay: Sivelestat(ONO5046; LY544349; EI546) 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.


Cell Assay: HUVEC are grown to confluence on fibronectin (25 μg/mL) coated Falcon cell culture inserts. Neutrophils stimulated by PAF (0.1 mM) are added to the HUVEC monolayers (upper chamber). The upper chamber is exposed to 2 mL of HUMEDIA and rehydrated at 37 ℃ for 1 h in the absence or the presence (50 μg/mL) of sivelestat. Subsequently, the upper chamber is removed and the fluid in the lower chamber is collected.

In VivoIntraoperative administration of sivelestat effectively reduced neutrophil induction and activation in the lung and improved oxygenation after cardiopulmonary bypass in a piglet model.By inhibiting neutrophil elastase, sivelestat has a direct action to the accumulated and activated leucocytes, offering efficient protection against the production of oxygen radicals and cytokines.
Animal modelNeonatal piglets
Formulation & DosageDissolved in 0.9% saline solution; 2 mg/kg/h; Intraoperative administration
