Baicalein Chemical Properties,Usage,Production
Description
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
Chemical Properties
Yellow Crystalline Solid
Uses
Baicalein is a flavonoid originally isolated from the roots of Scutellaria baicalensis Georgi. Several different functions of baicalein have been reported. Platelet 12-lipoxygenase is inhibited by baicalein with an ID50 value of 0.12 μM, with minimal inhibition of platelet cyclooxygenase-1 (IC50 = 0.83 mM). Baicalein inhibits lipid peroxidation, as assessed by production of TBARS, with an IC50 value of 5 μM. In addition to these effects, baicalein may play a role in apoptosis, as the compound inhibits cell growth of three human hepatocellular carcinoma cell lines with IC50 values ranging from 17-70 μg/ml.
Uses
antiviral (HIV)
Uses
An inhibitor of 12-lipoxygenase, leukotriene biosynthesis and release of lysosomal enzymes. It also inhibits cellular Ca2+ uptake and mobilization and adjuvant-induced arthritis. Baicalein is the fl avonoid component of Nepalese and Sino-Japanese crude drugs.
Uses
inhibitor of lipoxidase and leukotriene biosynthesis
Uses
An inhibitor of Ca2+ uptake, 5-LO, and 12-LO
Definition
ChEBI: A trihydroxyflavone with the hydroxy groups at positions C-5, -6 and -7.
General Description
Baicalein, a flavonoid, is a xanthine oxidase inhibitor. Anti-inflammatory effects of baicalein in peripheral human leukocytes has been studied.
Biological Activity
Inhibitor of 5- and platelet 12-lipoxygenases (IC 50 values are 9.5 and 0.12 mM respectively). Also inhibits Raf-mediated MEK-1 phosphorylation in C6 rat glioma cells and induces G1 and G2 cell cycle arrest by decreasing cdk1, cdk2, cyclin D2 and cyclin A expression. Anti-inflammatory in vivo .
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.
