Detailed Chemical

A detailed chemical investigation of the South China Sea soft corals Clavularia viridis and Lemnalia flava yielded four new halogenated laurane-type sesquiterpenoids, namely, isobromolaurenisol (1), clalaurenol A (2), ent-laurenisol (3), clalaurenol B (4), and the new aromadendrane-type sesquiterpenoid claaromadendrene (6), together with three known sesquiterpenoids (5, 7, and 8). Their structures were determined by extensive spectroscopic analysis and by comparison with the previously reported analogues. In a bioassay, compounds 1, 2 and 4 exhibited interesting inhibitory activities in vitro against PTP1B and NF-κB.

New Compounds

Two new steroidal glycosides, fragilioside A (1) and fragilioside B (2), along with five known compounds (3–7) were isolated from the gorgonian Dichotella fragilis (Ridleg) collected from the South China Sea. The structures of the new compounds (1 and 2) were elucidated by comprehensive analysis of spectral data, especially 2D NMR. The brine shrimp lethality and antifouling activity of the isolated compounds were also evaluated.
