Mycoversilin, a new antifungal antibiotic. II: Structure elucidation

The structure of a new antifungal antibiotic, mycoversilin, produced by Aspergillus versicolor (N5SZ)17 was determined as I by various spectroscopic and chemical methods. Mycoversilin is a unique polynuclear aromatic compound having two methyl and six hydroxyl groups and two ether linkages. The acetyl derivative prepared was found to have no antifungal property.
