Metabolic products of Aspergillus terreus. IV. Metabolites of the Strain IFO 8835. (2). The isolation and chemical structure of indolyl benzoquinone pigments.
Metabolic products of Aspergillus terreus. IV. Metabolites of the Strain IFO 8835. (2). The isolation and chemical structure of indolyl benzoquinone pigments.
Eleven kinds of bisindolyl-dimethoxyl-p-benzoquinones, "asterriquinones A-1, A-2, A-3, A-4, B-1, B-2, B-3, B-4, C-1, C-2, and D"were isolated from Aspergillus terreus IFO 8835, and their structures were determined. Asterriquinone D had the basic structure, and the others were substituted with dimethylallyl group (s) in the indole ring.
