Cubitanoids and Cembranoids from the Soft Coral Sinularia nanolobata

Two new cubitanoids, nanoculones A and B (1 and 2), and three new cembranoids, nanolobols A–C (3–5), as well as six known compounds, calyculone I (6), sinulariuol A (7), sinulariols C, D, H, and J (8–11), were isolated from the soft coral Sinularia nanolobata, collected off the coast of the eastern...

Sumario:Two new cubitanoids, nanoculones A and B (1 and 2), and three new cembranoids, nanolobols A–C (3–5), as well as six known compounds, calyculone I (6), sinulariuol A (7), sinulariols C, D, H, and J (8–11), were isolated from the soft coral Sinularia nanolobata, collected off the coast of the eastern region of Taiwan. Their structures were elucidated on the basis of extensive spectroscopic analysis. Cytotoxicity of compounds 1–11 was evaluated. The nitric oxide (NO) inhibitory activity of selected compounds was further measured by assay of lipopolysaccharide (LPS)-stimulated NO production in activated RAW264.7 cells. The results showed that none of 1–11 exhibited cytotoxicity against the tested cancer cell lines, whereas compound 8 was found to significantly reduce NO production.
