| Abstract |
Eight cyclic peroxide norterpenoids, compounds 1-8, have been isolated and characterized from the Red Sea sponge Diacarnus erythraeanus, including two new norsesterterpene derivatives (3, 4). Among these metabolites, (-)-muqubilin A (5) (nine cell lines analyzed) and the new compounds 3 and 4 (seven cell lines analyzed) displayed mean IC50 growth inhibitory concentrations in vitro of <10 mu M, while the remaining compounds (1, 6-8) were inactive in these cancer cell lines. Compound 5 displayed no selectivity between normal and cancer cells in terms of in vitro growth inhibition. Quantitative video microscopy analysis carried out on (-)-muqubilin A-treated cells validated the data obtained by means of the MTT colorimetric assay, while flow cytometry analysis revealed ROS production but no induction of apoptosis in cancer cells. |
