Clear solution
5% DMSO 95% Corn oil
0.83mg/ml Taking the 1 mL working solution as an example, add 50 μL of 16.6 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.

5.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明 Sivelestat sodium tetrahydrate (ONO5046-Na, EI546, LY544349) is a competitive inhibitor of human neutrophil elastase, also inhibits leukocyte elastase obtained from rabbit, rat, hamster and mouse.
in vitro Sivelestat suppresses both adhesion and transmigration of neutrophils to the endothelium[2].
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[1].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[3].

細胞アッセイ 細胞株 human umbilical vein endothelial cell (HUVEC)
濃度 1, 10, and 50 μg/mL
反応時間 1 h
実験の流れ

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.
