It has a role as a carcinogenic agent, a genotoxin, a Jacobaea metabolite, a mutagen, a rat metabolite and a human xenobiotic metabolite. It is a macrocyclic lactone, an organic heterotricyclic compound, an olefinic compound, a pyrrolizine alkaloid, a tertiary alcohol, a tertiary amine oxide, a primary alcohol and a diol. It is functionally related to a riddelliine."}]
