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.
