Περίληψη:
Four new tetracyclic brominated diterpenes, 1-4, were isolated from the organic extract of Sphaerococcus coronopifolius, collected from the rocky coasts of Corfu Island. The structures of the new natural products, as well as their relative configurations, were elucidated on the basis of extensive spectral analyses, including 2D-NMR experiments. The isolated metabolites were evaluated for their antibacterial activity against a panel of bacteria including multidrug-resistant (MDR) and methicillinresistant Staphylococcus aureus (MRSA) with MIC values in the range of 16-128 μg/ml. © 2010 Verlag Helvetica Chimica Acta AG.
