Ad. Rodriguez et al., UPROLIDES D-G .2. A RARE FAMILY OF 4,7-OXA-BRIDGED CEMBRANOLIDES FROMTHE CARIBBEAN GORGONIAN EUNICEA-MAMMOSA, Journal of natural products, 58(8), 1995, pp. 1209-1216
Five new cytotoxic cembranolides possessing a rare 4,7-oxa-bridged fun
ctionality were isolated from the gorgonian Eunicea mammosa. The struc
