生物活性:
Astragalin (Astragaline) a flavonoid with anti-inflammatory, antioxidant, anticancer, bacteriostatic activity. Astragalin inhibits cancer cells proliferation and migration, induces apoptosis. Astragalin is orally active and provides nerve and heart protection, and resistance against and osteoporosis.

体内研究:
Astragalin (25, 50, and 75 mg/kg; p.o.; once every two days; 25 d) reduces the tumor volumes, tumor weight and tumor formation rates and decreases expression of p-NFκB and p-iκκα in nude mouse model?with human colon cancer.Animal Model:Male BALB/c nude mice (4-week-old) with HCT116 cells (s.c.)
Dosage:0 mg/kg, 25 mg/kg, 50 mg/kg, 75 mg/kg
Administration:Oral gavage; once every two days; for 25 days
Result:Resulted tumor inhibition rates of 17.43%, 34.89% (p?< 0.01), and 67.06% with 25 mg/kg, 50 mg/kg, 75 mg/kg dose administration.Showed no effect on mouse weight.

体外研究:
Astragalin (0-80 μg/mL; 24 h, 48 h, 72 h) inhibits cancer cells viability and migration at 20, 40, 80 μM, and shows no cytotoxicity to normal human colon epithelial cell lines NCM460.Astragalin (80 μg/mL; 4 h, 8 h) interrupts the NF-κB signaling pathway and inhibits NF-κB P65 transcriptional activity in HCT116 cells stimulated by TNF-α.Astragalin (20, 40, 80 μg/mL; 48 h) induces HCT116 cells apoptosis and arrests cell cycle at G0/G1 phase.Astragalin (20, 40, 80 μg/mL; 48 h) increases the level of apoptin in HCT116 and decreases the level of anti-apoptotic proteins in a dose-dependent manner.
