Terphenylquinones are fungal dyes from the group of phenyl-substituted p-benzoquinones having the following general structure.
[1] General chemical structure of terphenylquinonesAlso derivatives with a central o-benzoquinone structure are known.
The biosynthesis of terphenylquinones is carried out by dimerization of substituted oxophenylpropanoic acids (phenylpyruvic acids).
Terphenylquinones are typical constituents of the Boletales.
