Three new 5,5,6,6,5-pentacyclic spongian diterpenes, spongenolactones A-C (<b>1</b>-<b>3</b>), were isolated from a Red Sea sponge <i>Spongia</i> sp. The structures of the new metabolites were elucidated by extensive spectroscopic analysis and the absolute configurations of <b>1-</b><b>3</b> were determined on the basis of comparison of the experimental circular dichroism (CD) and calculated electronic circular dichroism (ECD) spectra. Compounds <b>1</b>-<b>3</b> are the first 5,5,6,6,5-pentacyc ...[more]
