What is Chelerythrine?

The Uses of Chelerythrine

Chelerythrine Chloride is a cell permeable protein kinase C (PKC) inhibitor.

Definition

ChEBI: A benzophenanthridine alkaloid isolated from the root of Zanthoxylum simulans, Chelidonium majus L., and other Papaveraceae.

Biological Activity

Potent, cell-permeable inhibitor of protein kinase C (IC 50 = 660 nM); competitive with respect to the phosphate acceptor and non-competitive with respect to ATP. Has a wide range of biological activities, including antiplatelet, anti-inflammatory, antibacterial and antitumor effects. Activates MAPK pathways, independent of PKC inhibition. Inhibits binding of BclXL to Bak (IC 50 = 1.5 μ M) or Bad proteins and stimulates apoptosis.

Purification Methods

Chelerythrine crystallises from CHCl3 on addition of MeOH [Manske Can J Res 21B 140 1943, UV: Hruban et al. Coll Czech Chem Commun 35 3420 1970]. The pseudo base is colourless while the salts are yellow in aqueous solution and are fluorescent.
