Chelerythrine
Chelerythrine is a natural alkaloid, acts as a potent and selective Ca2+/phospholopid-dependent PKC antagonist, with an IC50 of 0.7 μM[1]. Chelerythrine has antitumor, antidiabetic and anti-inflammatory activity[2]. Chelerythrine inhibits the BclXL-Bak BH3 peptide binding with IC50 of 1.5 μM and displaces Bax from BclXL. Chelerythrine triggers apoptosis and autophagy[3][4].
