摘要
Chemical examination of the Chinese marine sponge Xestospongia testudinaria resulted in the isolation and characterization of twelve new brominated acetylenic acids, namely xestospongienols A-L (1a-1d, 2a-2d, and 3a-3d), together with the known analog 4. The structures of xestospongienols A-L were determined on the basis of 1D- and 2D-NMR, IR, and MS analysis in association with the modified Mosher method. The structural patterns are characteristic of brominated unbranched C(16)-alkyl chains containing polyene and acetylene moieties.
