The Red Sea soft coral Sarcophyton acutum ethyl acetate extract has afforded one new cembranoid; sarcacutumolid A (1), along with six known metabolites have been isolated from S. acutum for the first time (2-7). Chemical structures were elucidated by employing several spectroscopic analyses. The cytotoxic potential of the isolated compounds was assessed against four human cancer cell lines; hepatocellular (HepG2), cervical (HeLa), breast (MCF-7) and colorectal cancer (Colo-205). Sarcacutumolid A (1) and gorgosterol (7) inhibited colorectal cancer cell proliferation in a concentration-dependent manner with IC50 values of 35.5 and 44.0 μM, respectively.
