生物活性

製品説明

Sivelestat is a potent and selective inhibitor of neutrophil elastase with IC50 of 44nM. It almost shows no activity at a range of other proteases.

Targets

neutrophil elastase ^[1]

In Vitro
In vitro	sivelestat reduces the levels of inflammatory mediators by inhibiting NF-kB^[3]. It suppresses the growth of gastric cancer cells by inhibiting the release of TGF-α stimulated by NE^[2]; Sivelestat suppresses iNOS gene expression in proinflammatory cytokine-stimulated hepatocytes^[4].
細胞実験	細胞株	TMK-1 gastric carcinoma cells
	濃度	0.1–1000 µg/mL
	反応時間	24, 48 or 72 h
	実験の流れ	Gastric carcinoma cells are seeded into 96-well culture plates (5 × 10³ cells/well) in RPMI containing 7% FBS, 2.0 mM L-glutamine, and 1% nonessential amino acids. Following 24-h incubation in RPMI-1640 medium with 5% FBS, the cells are incubated for 24, 48 or 72 h at 37°C in a humidified atmosphere of 5% CO2 with varied concentrations (0.1–1.0 µg/mL) of NE, or with varied concentrations (0.1–1000 µg/mL) of sivelestat or with concentrations (10 and 100 ng/mL) of anti-TGF-α antibody in the presence of 1 µg/mL NE. After incubation, 10 µL of MTT solution (5 mg/mL) is added to each well and the plates are then incubated for 3 h at 37°C. The growth medium is then replaced with 150 µL of dimethyl sulfoxide (Wako) per well and the absorbance at 540 nm is measured using a Titertek Multiscan (Titertek, Huntsville, AL).

In Vivo
In Vivo	sivelestat could attenuate sepsis-related kidney injury in rats^[1]. It blocks GAPDH/Siah1 which is a novel signaling pathway during the progression of spinal cord injury^[5]. Administration of sivelestat attenuates pulmonary fibrosis after acute lung injury in mice.
動物実験	動物モデル	Male Sprague-Dawley rats
	投与量	50 or 100 mg/kg
	投与経路	i.p.
