| 摘要: | Three new cyathane diterpenoids, cyathin W (1), cyathin V (2), and cyathin T (3), were isolated from the solid culture of Cyathus africanus. The structures and configurations of these new compounds were elucidated on the basis of comprehensive spectroscopic analysis including 1D NMR, 2D NMR (HSQC, HMBC, NOESY), and HR-ESI-MS experiments. Compounds 1 and 3 showed moderate inhibition against nitric oxide production in lipopolysaccaride-activated macrophages with IC50 value of 80.07 and 88.87 muM, respectively. In cytotoxicity assay, compound 1 showed weak cytotoxicity against K562 cell line with IC50 value of 12.1 muM. |
