Oxygenated guaiane-type sesquiterpenes, xylaguaianols A-D (1-4), an iso-cadinane-type sesquiterpene isocadinanol A (5), and an α-pyrone 9-hydroxyxylarone (6), together with five known sesquiterpenes (7-11), and four known cytochalasins (12-15) were isolated from a culture broth of Xylaria sp. NC1214, a fungal endophyte of the moss Hypnum sp. The structures of all compounds were elucidated by the analysis of their spectroscopic data and relative configurations of 1-5 were determined with the help of NMR NOESY experiments. Cytochalasins C (12), D (13), and Q (14) were investigated for their cytotoxic activity against five tumor cell lines. Cytochalasin D showed significant cytotoxicity against all five cell lines, with IC50s ranging from 0.22 to 1.44 μM, whereas cytochalasins C and Q exhibited moderate, but selective cytotoxicity.
