Abstract

The Indonesian soft coral Nephthea chabrolii afforded two new oxygenated sesquiterpenes: hydroxycolorenone (1) and methexycolorenone (2), as well as the known liverwort metabolite (+)-cyclocolorenone (3). This is the first report of the occurrence of such terrestrial liverwort metabolites in marine soft corals. The structures of the new compounds were unambiguously established on the basis of NMR spectroscopic data ( ¹H, ¹³C, COSY, ¹H- detected direct and long-range ¹³C- ¹H correlations). Compound 1 exhibited insecticidal activity towards neonate larvae of the polyphagous pest insect Spodoptera littoralis, with an EC ₅₀ of 8.8 ppm and a LC ₅₀ of 453 ppm, when incorporated in artificial diet and offered to larvae in a chronic feeding bioassay.
