生物活性

Acacetin (5,7-Dihydroxy-4′-methoxyflavone) is an orally active flavonoid derived from Tephroseris kirilowii (Turcz.) Holub. Acacetin docks in the ATP binding pocket of PI3Kγ. Acacetin causes cell cycle arrest and induces apoptosis and autophagy in cancer cells. Acacetin has potent anti-cancer and anti-inflammatory activity and has the potential for pain-related diseases research[1][2].

体外研究
(In Vitro)

Acacetin (5,7-Dihydroxy-4′-methoxyflavone; 10-200 μM; 24 hours) decreases cell viabilities in a dose-dependent manner. Acacetin has little effect on human normal glial cell line HEB and non-tumorigenic epithelial cell line MCF-10A[1].
Acacetin (50-150 μM; 24 hours) causes G2/M cell cycle arrest and induces apoptosis and autophagy[1].
Acacetin (50-150 μM; 24 hours) leads to decreases in levels of PI3Kγ-p110, p-AKT, p-mTOR, p-p70S6K, and p-ULK in a dose-dependent manner[1].

Shanghai Jinpan Biotech Co Ltd has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay[1]

Cell Line: Breast cancer MCF-7 cells, hepatocellular carcinoma SMMC-7721 cells, lung adenocarcinoma A549 cells, esophageal carcinoma Eca109 cells

Cell Cycle Analysis[1]

Cell Line: MDA-MB-231 cells
Concentration: 50, 100, 150 μM

Western Blot Analysis[1]

Cell Line: MDA-MB-231 cells
Concentration: 50, 100, 150 μM
Incubation Time: 24 hours
Result: Resulted in decrease in levels of Bcl-2 and Bcl-xL and increase in levels of p53.
Led to decreases in levels of PI3Kγ-p110, p-AKT, p-mTOR, p-p70S6K, and p-ULK in a dose-dependent manner.
Had little or no effect on expression of PI3Kα, PI3Kβ, PI3Kδ, p-ERK, p-p38, and p-JNK.

体内研究
(In Vivo)

Acacetin (5,7-Dihydroxy-4′-methoxyflavone; 5, 20 mg/kg/day; orally; for 3 days) significantly suppresses microglial activation in an LPS-induced neuroinflammation mouse model[2].
Acacetin (25 mg/kg/day; orally; for 3 days) reduces neuronal cell death in an animal model of ischemia[2].
Acacetin (1.8-56.2 mg/kg/day; ip; single dose) decreases visceral and inflammatory nociception and prevented the formalin-induced oedema[3].
