Abstract
Four new briarane-related diterpenoids, designated as briaexcavatins C-F (1-4), were isolated from the Formosan octocoral Briareum excavatum, collected off southern Taiwan coast. The structures of these new metabolites were elucidated by the interpretation of spectroscopic and chemical methods. The configuration of 1 was further supported by molecular mechanics calculations. Briarane 1 has been shown to exhibit mild cytotoxicity toward MDA-MB-231 human breast tumor cells and briarane 3 was found to show activity to inhibit neutrophil elastase release in humans.
