ChEBI: Riddelliine N-oxide is a pyrrolizine alkaloid that is 13,19-didehydrosenecionane bearing two additional hydroxy substituents at positions 12 and 18, two additional oxo groups at positions 11 and 16 and an N-oxido substituent. 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.
