Marine diterpenoids with a briarane skeleton from the Okinawan soft coral Pachyclavularia violacea
Abstract
Five new briarane-type diterpenoids, pachyclavulides E (5), F (6), G (7), H (8) and I (9), were isolated from the Okinawan soft coral Pachyclavularia violacea. The structures of these compounds were elucidated based on the results of spectroscopic analysis. Compound 5 showed a weak growth-inhibitory activity in vitro toward cancer cells.
