Structures and Cytotoxic Evaluation of New and Known Acyclic Ene-Ynes from an American Samoa Petrosia sp. Sponge
摘要:
Four new compounds, (-)-petrosynoic acids A D (1-4), and five known congeners, pellynols A (5), C (6), D (7), F (8), and I (9), were isolated from a Petrosia sp. marine sponge collected in American Samoa. Isolation work was guided by cytotoxicity against human lung cancer cells (H460). The structures of the C-31-C-33 polyacetylenes (1-9) were determined on the basis of 1D- and 2D-NMR analysis, mass spectrometry, and comparison of specific rotation values. Compounds 1-9 were found to be broadly cytotoxic with limited selectivity for cancer cells, as they were all moderately active against the A2058 (melanoma), H522-T1 (lung), and H460 (lung) human cancer cell lines as well as IMR-90 quiescent human fibroblast cells.
