What is Cladofulvin?

Plain description, key identifiers and synonyms

Cladofulvin is a bianthracene homodimer composed of two nataloe-emodin moieties linked by an aryl-aryl bond. 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 member of bianthracenes, a polyphenol and a trihydroxyanthraquinone. It is functionally related to a nataloe-emodin. It is a conjugate acid of a cladofulvin(2-).
