Three known nucleosides were isolated from the sponge Haliclona sp. The structures were established on the basis of NMR data and comparison with those reported, and chemotaxonomic relationships of the sponge nucleosides were discussed.
متن کاملCyclic Bis-1,3-dialkylpyridiniums from the Sponge Haliclona sp.
Eight novel cyclic bis-1,3-dialkylpyridiniums, as well as two known compounds from the cyclostellettamine class, were isolated from the sponge Haliclona sp. from Korea. Structures of these novel compounds were determined using combined NMR and FAB-MS/MS analyses. Several of these compounds exhibited moderate cytotoxic and antibacterial activities against A549 cell-line and Gram-positive strains...

متن کاملTwo New Cytotoxic Candidaspongiolides from an Indonesian Sponge
Marine sponges have been recognized as potentially rich sources of various bioactive molecules. In our continuing search for new secondary metabolites from Indonesian marine invertebrates, we collected a sponge, whose extract showed cytotoxicity against cultured cells at 0.1 μg/mL. Purification of the extract yielded two new macrolides 2 and 3 along with known candidaspongiolide (1). The struct...
متن کاملNovel Adociaquinone Derivatives from the Indonesian Sponge Xestospongia sp.
Seven new adociaquinone derivatives, xestoadociaquinones A (1a), B (1b), 14-carboxy-xestoquinol sulfate (2) and xestoadociaminals A-D (3a, 3c, 4a, 4c), together with seven known compounds (5-11) were isolated from an Indonesian marine sponge Xestospongia sp. Their structures were elucidated by extensive 1D and 2D NMR and mass spectrometric data. All the compounds were evaluated for their potent...
