Three new brominated fatty acids, (5E, 11E, 15E, 19E)-20-bromoeicosa-5, 11, 15, 19-tetraene-9, 17-diynoic acid (1), (5Z, 11E, 15E, 19E)-6, 20-dibromoeicosa-5, 11, 15, 19-tetraene-9, 17-diynoic acid (2) and (Z E)-14, 14-dibromo-4, 6, 13-tetradecatrienoate, characterized as the methyl ester, 3, were isolated from Xestospongia sp. from the Indian Ocean. Compounds 1 -2 (C-20) and 3 (C-14) are brominated fatty acids of unusual carbon number that have not been encountered previously in marine invertebrates. Xestospongia sp. is an association of sponge cells and bacteria, the latter accounting for ca. 50% of cellular mass.
