| 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 Vivo | Intraoperative 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 model | Neonatal piglets |
| Formulation & Dosage | Dissolved in 0.9% saline solution; 2 mg/kg/h; Intraoperative administration |
