Eleven new dihydronaphthalenones 1-11, together with five known compounds; 5-hydroxydihydrofusarubin C (12), javanicin, bostrycoidin, anhydrofusarubin, and 3-O-methylfusarubin, were isolated from the endophytic fungus Fusarium sp. BCC14842. Structures were elucidated by analyses of the NMR spectroscopic and mass spectrometry data. Javanicin, 3-O-methylfusarubin, compounds 3 and 7 exhibited antimycobacterial and cytotoxic activities. Javanicin also displayed antifungal activity with IC50 of 6.16 mu g/mL, while compounds 2, 4, 5, 8, and 12 showed only cytotoxic activity. (C) 2011 Elsevier Ltd. All rights reserved.
