Metabolite Identification
Common NameHarmaline
DescriptionHarmaline, also known as dihydroharmine or harmidine, belongs to the class of organic compounds known as harmala alkaloids. Harmala alkaloids are compounds with a structure based on harmaline, harmine, harmalol, harman or a derivative of those parents. These parents are beta-carbolines, consisting of a pyrimidine fused to the pyrrole moiety of an indole to form a pyrido[3,4-b]indole. Harmaline is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a significant number of articles have been published on Harmaline.
