Sesterterpenoids, terretonins A-D, and an alkaloid, asterrelenin, from Aspergillus terreus.
Four new sesterterpenoids, terretonins A-D (1-4), and a new alkaloid, asterrelenin (5), together with five known compounds, were isolated from the ethyl acetate extract of a solid-state fermented culture of Aspergillus terreus. Their structures were elucidated on the basis of spectroscopic analysis. The structures of 1, 2, and 5 were confirmed by X-ray crystallographic analysis.
