| Abstract: | Six eremophilane sesquiterpenes were obtained from a marine fungus Penicillium sp. BL27-2. Their structures were elucidatedas 3-acetyl-9, 7 (11)-dien-7ot-hydroxy-8-oxoeremophilane (1), 3-acetyl-13-deoxyphomenone (2), Sporogen-AO 1 (3), 7-hydro-xypetasol (4), 8α-hydroxy-13-deo -xyphomenone (5) and 6-dehydropetasol (6) based on detailed NMR analysis. 1 was a newcompound and 2 was obtained as a new natural compound. These compounds were assayed for their cytotoxic activity on P388,A549, HL60, BEL7402 and K562 cell lines by the MTT method. The assay results suggested the epoxide tings in eremophilanemolecules were essential for their activity, and acetylation could enhance their activity.2008 Yong Fu Huang.
