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

Previous studies suggest baicalein, in addition to its antioxidant effects, protects against hypoxia/reoxygenation injury via its pro-oxidant properties. We hypothesize that a brief period of baicalein treatment prior to ischemia/reperfusion (I/R) may trigger preconditioning protection via a mitochondrial pro-oxidant mechanism.

To evaluate the possible mechanisms responsible for the anti-inflammatory effects of baicalin or baicalein, phorbol-12-myristate-13-acetate (PMA)- or N-formyl-methionyl-leucyl-phenylalanine (fMLP)-activated inflammatory responses of peripheral human leukocytes were studied. Both baicalin and baicalein diminished fMLP- or PMA-induced reactive oxygen intermediates production in

Baicalein, one of the major flavonoids found in Scutellaria baicalensis Georgi, displays neuroprotective effects on experimental models of Parkinson's disease (PD) in vitro and in vivo. Although the antioxidative and/or anti-inflammatory activity of baicalein likely contributes to these neuroprotective effects
