کلریت‌رین

Also known as broussonpapyrine, cheleritrine, chelerythrine hydroxide, toddalin, 1,2-Dimethoxy-12-methyl(1,3)benzodioxolo(5,6-c)phenanthridinium

Chelerythrine is a benzophenanthridine alkaloid present in the plant Chelidonium majus (greater celandine). It is a potent, selective, and cell-permeable protein kinase C inhibitor in vitro. And an efficacious antagonist of G-protein-coupled CB1 receptors. This molecule also exhibits anticancer qualities and it has served as a base for many potential novel drugs against cancer. Structurally, this molecule has two distinct conformations, one being a positively charged iminium form, and the other being an uncharged form, a pseudo-base.
