摘要
Drimane-type sesquiterpenoids are widely distributed in fungi. From the ethyl acetate extract of the earwig-derived As-pergillus sp. NF2396, seven new drimane-type sesquiterpenoids, named drimanenoids A-G (1-7), were isolated. Their structures were elucidated by diverse spectroscopic analysis including high-resolution ESI-MS, one-and two-dimensional NMR spectroscopy. Drim-anenoids A-F (1-6) are new members of drimane-type sesquiterpenoid esterified with unsaturated fatty acid side chain at C-6. Drim-anenoids C (3), D (4) and F (6) showed antibacterial activity against five types of bacteria with different inhibition diameters. Drim-anenoid D (4) exhibited moderate cytotoxicity against human myelogenous leukemia cell line K562 with an IC50 value of 12.88 +/- 0.11 mu mol center dot L-1.
