Description
Chelerythrine chloride is the chloride form of Chelerythrine chloride which is a benzophenanthridine alkaloid isolated from the plant Chelidonium majus (greater celandine). It is a kind of potent, selective, and cell-permeable protein kinase C inhibitor, an efficient antagonist of G-protein-coupled CB1 receptors, and an independent activator of MAPK pathways. It has a wide range of biological activities including antiplatelet, anti-inflammatory, antibacterial and antitumor effects. It has reported of that it is capable of inducing apoptosis in HL-60 human promyelocytic leukemia cells and several other cancer cell lines. The underlying mechanism is through its effects of inhibiting the binding of BclXL to Bax or Bad.

Uses
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.
