Abstract

A chemical investigation of the organic extract of the sea hare Aplysia depilans, collected off Skyros Island, Greece, yielded eight new brominated diterpenes (1-8), featuring the rare dactylomelane skeleton, together with the previously reported luzodiol (9). The structure elucidation and the assignment of the relative configurations of the new natural products were based on extensive NMR spectroscopic and MS spectrometric analyses. Compounds 1-9 were evaluated for their cytotoxic activities against five human tumor cell lines, but were proven inactive.
