生物活性

Luteolin (Luteoline), a flavanoid compound, is a potent Nrf2 inhibitor. Luteolin has anti-inflammatory, anti-cancer properties, including the induction of apoptosis and cell cycle arrest, and the inhibition of metastasis and angiogenesis, in several cancer cell lines, including human non-small lung cancer cells.

性状

Solid

体外研究(In Vitro)

Luteolin (0-160 μM; 24 hours; NCI-H460 cells) treatment inhibits the viability of NCI-H460 cells in a concentration-dependent manner.
Luteolin (20-80 μM; 24 hours; NCI-H460 cells) treatment causes an accumulation of cells in the S phase.
Luteolin (320-580 μM; 48 hours; NCI-H460 cells) treatment induces apoptosis.
Luteolin (20-80 μM; 24 hours; NCI-H460 cells) treatment increases the protein expression levels of apoptotic regulatory proteins, including the Bax/Bcl-2 ratio, in a concentration-dependent manner, however, only 80 μM Luteolin inhibits the expression of Bad. Luteolin also decreases the expression of Sirt1 in the NCI-H460 cell line in a concentration-dependent manner.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究(In Vivo)

Luteolin (10-100?mg/kg; oral gavage; daily; for 12 weeks; adult male Wistar rats) has an antioxidant effect and can also protect against non-alcoholic steatohepatitis through targeting the pro-inflammatory IL-1 and Il-18 pathways in rats with a high carbohydrate/high fat diet.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:	Adult male Wistar rats (200-220?g)
Dosage:	10 mg/kg, 25 mg/kg, 50 mg/kg or 100?mg/kg
Administration:	Oral gavage; daily; for 12 weeks
Result:	Significantly reduced ALT and AST activity and reduced levels of bilirubin, hyaluronic acid and malondialdehyde. Shows an antioxidant activity such as a significant increase in reduced glutathione. IFN-γ, TNF-α, IL-1α and IL-18 levels decreased significantly.
