It is a phytotoxin which was first isolated from the pathogenic soybean fungus, Cercospora kikuchii and later found in multiple members of the genus Cercospora. It has a role as a photosensitizing agent, a phytotoxin, a fungal metabolite and a reactive oxygen species generator. It is a polyphenol, a polyketide and an organic heterohexacyclic compound. It is a conjugate acid of a cercosporin(2-)."}]
