Triangulene C, a new cubitane-based diterpenoid from the soft coral Sinularia triangula

摘要

A new cubitane-based diterpenoid, triangulene C (1), was isolated from the soft coral Sinularia triangula and its structure was elucidated on the basis of spectroscopic data. Compound 1 was not cytotoxic (IC _(50) >20 μg/mL) toward the four human cancer cell lines tested (HL60, MDA-MB-231, HCT-116 and DLD-1).
