چکیده
A new C47 polyoxygenated acetylenic acid, nepheliosyne B (2), along with the previously described nepheliosyne A (1), have been isolated from the New Caledonian marine sponge Niphates sp. Their structures have been elucidated on the basis of extensive spectroscopic analyses. These metabolites exhibited a moderate cytotoxicity against K562, U266, SKM1, and Kasumi cancer cell lines.

Two new long-chain C33 polyacetylenic compounds, halicynones A and B were isolated from the marine sponge Haliclona sp. along with known analogs. The known compound pellynol A possessing a 1-yn-3-ol terminus, exhibited strong antitumor activity against the human colon tumor cell line HCT-116 (IC50 0.026 μg/mL), however, the corresponding 1-yn-3-one, halicynone A, was inactive, which suggests an...
