1-Formamido-abeo-pupukeanane (1) and 2-formamidopupukeanane (2) were isolated from the nudibranch Phyllidia coelestis
Bergh., and chemical structures were elucidated base on spectroscopic methods, X-ray diffraction and CD analysis. The structure of 1 was proposed to be an unprecedented rearranged tricyclic sesquiterpene derived from the parent skeleton of sesquiterpenes in pupukeanane family. The two compounds were tested for the cytotoxicity against HeLa, MCF-7, KB and HT-29 to show moderate to good activity.
