Common NameXanthomegnin
ClassSmall Molecule
DescriptionXanthomegnin is a mutagenic mycotoxin isolated from Penicillium citreo-viride. It is known to cause nephropathy and death in farm animals exposed to food-borne Penicillium (and Aspergillus fungi). In humans and animals, oral intake of xanthomegnin leads to kidney and liver abnormalities, often first presenting as jaundice. Death may result. The compound has been shown to interfere with cellular respiratory processes and has given positive results in tests for genotoxic potential.
