| Abstract: | Eight new chromones, engyodontiumones A–H (1–8), and three new phenol derivatives (9–11) together with eight known polyketides (12–19) were isolated from the deep-sea-derived fungus Engyodontium album DFFSCS021. Their structures were identified by extensive spectroscopic analysis. Compounds 8 and 16 showed significant selective cytotoxicity against human histiocytic lymphoma U937 cell line with IC50 values of 4.9 and 8.8 μM, respectively. In addition, this is the first time to report that 8, 15 and 16 had mild antibacterial activity against Escherichia coli and Bacillus subtilis, and 15 showed potent antilarval activity against barnacle Balanus amphitrite larval settlement. |
