Chemical Constituents of the Fungus Veronaea sp.

A new compound, isodihydroprehelminthosporol (1), and five known compounds, dihydroprehelminthosporol (2), 4-(2-hydroxyethyl)phenol (3), anhydrocochlioquinone A (4), isocochlioquinone A (5), and cochlioquinone A (6), were isolated from the fungus Veronaea sp. 1.03621. Their structures were elucidated using spectroscopic methods, mainly 1 D and 2 D NMR. These compounds were tested for their cytotoxicity towards two human cancer cell lines, A549 and SK-OA-3, and exhibited different activity.
