Erinacol (cyatha-3,12-dien-14beta-ol) and 11-O-acetylcyathin A3, new cyathane metabolites from an erinacine Q-producing Hericium erinaceum.
In our search for new cyathane metabolites related to the biosynthesis of erinacine Q in Hericium erinaceum, we isolated a novel cyatha-3,12-dien-14beta-ol named erinacol together with known 11-O-acetylcyathatriol (the erinacine Q aglycon) and new metabolite 11-O-acetylcyathin A(3) from the mycelial extract. The structure of each compound was determined by spectral methods. Possible biosynthetic relationships of these metabolites are discussed from their structural features.
