Berberine chloride (NSC 646666)Berberine chloride (NSC 646666, Natural Yellow 18) is a quaternary ammonium salt from the group of isoquinoline alkaloids. Berberine activates caspase 3 and caspase 8, cleavage of poly ADP-ribose polymerase (PARP) and the release of cytochrome c. Berberine chloride decreases the expression of c-IAP1, Bcl-2 and Bcl-XL. Berberine chloride induces apoptosis with sustained phosphorylation of JNK and p38 MAPK, as well as generation of the ROS. Berberine chloride is a dual topoisomerase I and II inhibitor. Berberine chloride is also a potential autophagy modulator. |
