Abstract
Massileunicellins A (7), B (9), and C (11) - which show a novel type of a s econd epoxy bridge in eunicellane diterpenes - were isolated from the gorgo nian Eunicella cavoliniii collected near Marseille. Structural assignments are based on NMR and MS data of these compounds and of their ketal derivati ves 8, 10, and 12. Negligible activity of the massileunicellins on L1210 an d KB tumor cell lines, and similar results for related known compounds, cas t doubt on high cytotoxicity reported for the latter by other authors.
