Metabolite Identification
Common NameN-Methylporphyroxine
DescriptionN-Methylporphyroxine, also known as N-methylpapaverrubine D, belongs to the class of organic compounds known as rhoeadine alkaloids. These are alkaloids with a structure based on rhoeadine. They usually contain a benzazepine system fused with a six-membered hemiacetal or acetal. N-Methylporphyroxine is a very strong basic compound (based on its pKa). Alkaloid from Papaver somniferum (opium poppy).
