Mechanism of Action

Targets/IC₅₀/Ki	VEGFR2 kinase
In vitro	Taxifolin (Dihydroquercetin) is not mutagenic and low toxic compared to Qercetin. It acts as a potential chemopreventive agent by regulating genes via an ARE-dependent mechanism. This compound has shown to inhibit the ovarian cancer cell growth in a dose-dependent manner.
