Chlorine-containing polyacetoxybriarane diterpenoids from the octocoral Junceella fragilis

The chemical screening of an octocoral identifed as has led to the isolation of five chlorinated briarane-type diterpenoids, including three known metabolites, gemmacolide X (1), frajunolide I (2), and fragilide F (3), along with two new analogs, 12α-acetoxyfragilide F (4) and 12α-acetoxyjunceellin...

description The chemical screening of an octocoral identifed as has led to the isolation of five chlorinated briarane-type diterpenoids, including three known metabolites, gemmacolide X (1), frajunolide I (2), and fragilide F (3), along with two new analogs, 12α-acetoxyfragilide F (4) and 12α-acetoxyjunceellin (5). Single-crystal X-ray diffraction analysis was carried out to determine the absolute configurations of 1 and 2, while the structures of new compounds 4 and 5 were ascertained with 2D NMR experiments. Briaranes 1 and 3-5 were active in enhancing alkaline phosphatase (ALP) activity.
