生物活性

Farrerol is a bioactive constituent of Rhododendron, with broad activities such as anti-oxidative, anti-inflammatory, anti-tumor, neuroprotective and hepatoprotective effects[1][2][3][4][5][6].

体外研究
(In Vitro)

Farrerol observably reduces the production of inflammatory mediators including IL-1β, IL-6, TNF-α, COX-2, and iNOS in LPS-induced RAW264.7 cells via suppressing AKT, ERK1/2, JNK1/2, and NF-κB p65 phosphorylation[1].
Farrerol attenuates β-amyloid-induced oxidative stress and inflammation through Nrf2/Keap1 pathway in a microglia cell line[2].
Farrerol inhibits angiogenesis through Akt/mTOR, Erk and Jak2/Stat3 signal pathway[3].
Farrerol overcomes the invasiveness of lung squamous cell carcinoma cells by regulating the expression of inducers of epithelial mesenchymal transition[4].
Farrerol ameliorates acetaminophen-induced hepatotoxicity via activation of Nrf2 and autophagy[6].
