AbstractEight cembrane-type diterpenoids, namely, (+)-(6R)-6-hydroxyisosarcophytoxide (1), (+)-(6R)-6-acetoxyisosarcophytoxide (2), (+)-17-hydroxyisosarcophytoxide (3), sarcomililatins A-D (4-7), and sarcomililatol (8), were isolated from the soft coral Sarcophyton mililatensis collected from Weizhou Island, Guangxi Autonomous Region, together with 2 known related analogues, (+)-isosarco phytoxide (9) and (+)-isosarcophine (10). The structures of these compounds were elucidated by a combination of detailed spectroscopic analyses, chemical methods, and comparison with reported data. The absolute configuration of compound 1 was established by the modified Mosher's method, while the absolute configurations of compounds 4 and 5 were assigned by electronic circular dichroism (ECD) spectroscopy and that of compound 8 was established by time-dependent density functional theory electronic circular dichroism (TD-DFT ECD) calculation. In in vitro bioassays, compound 9 displayed significant cytotoxicity against the human cancer cell lines human promyelocytic leukemia cells (HL-60) and human lung adenocarcinoma cells (A-549) with IC50 values of 0.78 +/- 0.21 and 1.26+0.80 +/- 1.26+0.80 mu mol/L, respectively. Compounds 4 and 9 also showed moderate inhibitory effects on the TNF alpha-induced Nuclear factor kappa B (NF-kappa B, a therapeutical target in cancer) activation, showing IC50 values of 35.23 +/- 12.42 and 22.52 +/- 4.44 mu mol/L, respectively.
