Glyscavins A, B and C, New Phenolic Glycoside Antioxidants Produced by a Fungus Mycelia sterilia F020054
New melanin synthesis inhibitors, melanocins A, B and C, were isolated from the fermentation broth and extract of mycelium of Eupenicillium shearii F80695. The structures of melanocins were established by spectroscopic methods. They are formamide compounds. In particular, melanocin A has an isocyanide group.
