General description

Baicalein, a flavonoid, is a xanthine oxidase inhibitor. Anti-inflammatory effects of baicalein in peripheral human leukocytes has been studied.

Application

Baicalein was used in a study to investigate the in vitro quantitative inhibition of lipoxygenase.

Biochem/physiol Actions

The flavonoid component of Nepalese and Sino-Japanese crude drugs. Baicalein, a major flavone of Scutellariae baicalensis, inhibits the 12-lipoxygenase (12-LOX) pathway of arachidonic acid metabolism, which inhibits cancer cell proliferation and induces apoptosis.
