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 phytotoxin, a photosensitizing agent, a reactive oxygen species generator and a fungal metabolite. It is a polyketide, a polyphenol and an organic heterohexacyclic compound. It is a conjugate acid of a cercosporin(2-).

使用Cercosporin is a perylenequinone reported in 1957 as the causative agent of soy bean purple speck disease due to the fungal pathogen, Cercsopsorium kikuchii, which is widely found in species of the Cercosporium genus. Cercosporin phytotoxicity is light-activated and this process contributes to a wider biological profile as a photodynamic antiviral and antitumor active. Cercosporin (CGP049090) is an antagonist of Tcf4/b-catenin signalling, inhibiting the expression of survivin and inducing apoptosis in several tumour cell lines.
