Definition
ChEBI: A biflavonoid that is apigenin substituted by a 4-(5,7-dihydroxy-4-oxo-4H-chromen-2-yl)phenoxy group at position 6. A diflavonyl ether, it is isolated from Rhus succedanea and has been found to possess significant cytotoxic
otential.
Biological Activity
Hinokiflavone is a plant biflavone th at exhibit potent anticancer, hepatoprotective, antibacterial, antiviral, and anti-inflammatory activities. Hinokiflavone induces apoptosis and cell cycle arrest, and blocks migration and invasion of melanoma cells. It is a potent inhibitor of dengue 2 virus RNA-dependent RNA polymerase (DV-NS5 RdRp). Hinokiflavone is a modulator of pre-mRNA splicing in cells. It increases SUMOylation of a subset of spliceosome proteins by inhibiting SENP1 protease activity. It induces apoptosis in esophageal squamous cell carcinoma (ESCC) through regulation of PI3K/AKT/mTOR pathway.
