Baicalein Chemical Properties,Uses,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

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

Uses

inhibitor of lipoxidase and leukotriene biosynthesis

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.

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.
