Four previously unreported chemical entities, boydone A (1), boydone B (2), botryorhodine F (3), and botryorhodine G (4), along with five known compounds, fusidilactone A (5), (R)-(-)-mevalonolactone (6), (R)-(-)-lactic acid (7), ovalicin (8), and botryorhodine C (9), were isolated from the ethyl acetate extracts of the fermented broths of the fungal strain Pseudallescheria boydii NTOU2362. The structures of 1-9 were characterized on the basis of their spectroscopic data analyses. The absolute configurations of 1 and 2 were established by comparison with the literature and the modified Mosher's method. The growth inhibitory activities of 1-9 against the A549 non-small-cell lung cancer cell line were evaluated, and 2 and 8 exhibited moderate to potent bioactivities with GI50 values of 41.3 and 4.1 μM, respectively, in comparison with fluorouracil (GI50 = 3.6 μM).
