Anti-inflammatory norditerpenoids from the soft coral Sinularia maxima

Chemical investigation of the soft coral Sinularia maxima resulted in the isolation of seven norditerpenoids, including two new compounds, 12-hydroxy-scabrolide A (2) and 13-epi-scabrolide C (6). The structures of the isolated compounds were elucidated based on extensive spectroscopic evidence including Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS) and both one- and two-dimensional nuclear magnetic resonance (1D and 2D...
