It is a secondary metabolite isolated from the fungal tomato pathogen Cladosporium fulvum. It has a role as a biological pigment and a fungal metabolite. It is a trihydroxyanthraquinone, a polyphenol and a member of bianthracenes. It is functionally related to a nataloe-emodin. It is a conjugate acid of a cladofulvin(2-)."}]
