Cembranoids from the Cultured Soft Coral Sinularia Gibberosa [PDF]
Natural Product Communications, 2013 An EtOAc extract of the cultured soft coral Sinularia gibberosa yielded a new cembrane-based diterpenoid, cugibberosene A (1), together with the previously reported three cembranoids (2–4). The structure determination was based on extensive NMR studies.

Lobocrassins A–E: New Cembrane-Type Diterpenoids from the Soft Coral Lobophytum crassum
Marine Drugs, 2011 Five new cembrane-type diterpenoids, lobocrassins A–E (1–5), were isolated from the soft coral Lobophytum crassum. The structures of cembranes 1–5 were established by spectroscopic and chemical methods and by comparison of the spectral data with those of

Biscembranoids and Cembranoids from the Soft Coral Sarcophyton elegans [PDF]
Marine Drugs, 2017 Two novel biscembranoids, sarelengans A and B (1 and 2), five new cembranoids, sarelengans C–G (3–7), along with two known cembranoids (8 and 9) were isolated from the South China Sea soft coral Sarcophyton elegans. Their structures were determined by spectroscopic and chemical methods, and those of 1, 4, 5, and 6 were confirmed by single crystal X-ray
