Two new cadinane-type sesquiterpenoids, scabralins A (1) and B (2) were obtained from the soft coral Sinularia scabra. Metabolite 1 was shown to exhibit moderate to weak cytotoxicity against MCF-7, WiDr, Daoy, and HEp 2 cancer cell lines. Also, incubation with 10 μM compound 1 significantly inhibited the accumulation of the pro-inflammatory inducible nitric oxide synthase protein in lipopolysaccharide-stimulated RAW264.7 macrophage cells.

A new flavonoid glycoside, globlin A (1), and eleven known compounds were isolated from methanolic extracts of the leaves of Glochidion obliquum. The structure of this new compound was established with a combination of 2D NMR techniques (COSY, NOESY, HMQC and HMBC) and HR-ESI-MS analyses. Chemical structures of the other known compounds were identified by comparison of their spectroscopic and physical data with those reported in the literature. Some of the isolates were examined for their bioactivities. Among the tested compounds, rotundic acid (4) displayed significant cytotoxicity and anti-inflammatory activities.
