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.

How to use

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. Acacetin (50-150 μM; 24 hours) causes G2/M cell cycle arrest and induces apoptosis and autophagy. 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.

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. Acacetin (25 mg/kg/day; orally; for 3 days) reduces neuronal cell death in an animal model of ischemia. Acacetin (1.8-56.2 mg/kg/day; ip; single dose) decreases visceral and inflammatory nociception and prevented the formalin-induced oedema.
