A new epitetrathiodioxopiperizine, secoemestrin D (1), five sesterterpenoids bearing a new carbon skeleton, emericellenes A–E (2–6), together with previously known fungal metabolites, sterigmatocystin (7), arugosin C (8), and epiisoshamixanthone (9), were obtained from the endophytic fungal strain Emericella sp. AST0036 isolated from a healthy leaf tissue of Astragalus lentiginosus. The planar structures and relative configurations of the new metabolites 1–6 were elucidated using MS, 1D and 2D NMR spectroscopic data. All compounds were evaluated for their potential anticancer activity using a panel of six tumor cell lines and normal human fibroblast cells. Only metabolites 1 and 7 showed cytotoxic activity. More importantly, secoemestrin D (1) exhibited significant cytotoxicity with IC50s ranging from 0.06–0.24 µM and moderate selectivity to human glioma (SF-268) and metastatic breast adenocarcinoma (MDA-MB-231) cell lines.
