Metabolite Identification
Common NameProtopine
DescriptionProtopine, also known as corydinine or fumarine, belongs to the class of organic compounds known as protopine alkaloids. These are alkaloids with a structure based on a tricyclic protopine formed by oxidative ring fission of protoberberine N-metho salts. Based on a literature review a significant number of articles have been published on Protopine.
