Like all ergopeptides,<unk>  is a cyclol; two peptide groups of its tripeptide moiety are crosslinked, forming the >N-C(OH)< juncture between the two rings with the amide functionality.<unk>  is a semisynthetic derivative of a natural ergot alkaloid, ergocryptine (a derivative of lysergic acid), which is synthesized by<unk> ination of ergocryptine using N-bromosuccinimide. 400px
