Oxygenated Cembranoids from the Soft Coral Sinularia flexibilis [PDF]
International Journal of Molecular Sciences, 2013 Chemical examination of the Taiwanese soft coral Sinularia flexibilis led to the isolation of five cembrane-based diterpenoids 1–5, including two new metabolites, 11-acetylsinuflexolide (1) and 11-acetyldihydrosinuflexolide (2). The structures of the new metabolites were determined based on extensive spectroscopic analysis, particularly mass ...
