Antibacterial anthraquinone dimers from marine derived fungus Aspergillus sp

Fitoterapia, 2019
As a continue investigation of the bioactive secondary metabolites from marine derived fungi, two new anthraquinone dimers (1, 2), along with three known anthraquinones (3-5) and two known xanthones (6, 7) were isolated from the marine-derived fungus Aspergillus versicolor. Their structures, including the absolute configurations, were elucidated by NMR,

Isocoumarin derivatives from the marine-derived fungus Phoma sp. 135

Tetrahedron Letters, 2016
Abstract The dihydro-isocoumarin derivatives 1 – 2 were isolated from the marine-derived fungus Phoma sp. 135. Structural elucidation was achieved through extensive spectroscopic evaluation including 1D- and 2D-NMR, accurate mass measurements, and single crystal X-ray diffraction analysis. We report herein the structure and absolute configuration
