Cytotoxic Drimane Sesquiterpenoids Isolated from Perenniporia maackiae

초록

A chemical investigation of a basidiomycetes fungus, Perenniporia maackiae, led to the discovery of 12 drimane sesquiterpenoids, including seven new constituents (1-7). The elucidation of the structures was performed via interpreting extensive spectroscopic methods, including ECD calculations. Among all isolated compounds, 1, 2, and 6 exhibited cytotoxicity toward six carcinoma cells, including ACHN, HCT-15, MDA-MB-231, NCI-H23, NUGC-3, and PC-3 cells, with half-maximal inhibition of cell proliferation values of 1.2-6.0 mu M.
