Six novel rearranged spongian diterpenes were isolated from the New Zealand sponge Chelonaplysilla violacea . The structures of the six metabolites were determined by extensive spectral analysis. Three of the new compounds possess anti‐inflammatory activity. Pourewic acid A ( 4 ) and 15‐methoxypourewic acid B ( 5 ) represent possible intermediates in previously described biogenetic pathways. Pourewanone ( 3 ) is the first example of a formate to be isolated from the marine environment. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
