Description and Uses

Baicalein (491-67-8) is an inhibitor of protein tyrosine kinase in leukemia (CEM) cells. Induces cell cycle arrest and apoptosis.1?Originally reported as a selective inhibitor of 12-lipoxygenase, baicalein has since been shown to inhibit both 12-LO and 15-LO (IC50=0.64 μM for 12-LO and 1.6 μM for 15-LO).2 Baicalein displays anti-inflammatory activity and inhibits adjuvant-induced arthritis. Also inhibits prolyl oligopeptidase (IC50=36 μM).3

An inhibitor of Ca2+ uptake, 5-LO, and 12-LO
