Structure, Synthesis, and Biological Activity of a C-20 Bisacetylenic Alcohol from a Marine Sponge Callyspongia sp.
摘要:
An optically inactive C-20 bisacetylenic alcohol, (4E,16E)-icosa-4,16-diene-1,19-diyne-3,18-diol, was isolated from a marine sponge Callyspongia sp. as a result of screening of antilymphangiogenic agents from marine invertebrates. An optical resolution using chiral-phase HPLC gave each enantiomer, (-)-1 and (+)-2. Because the natural and synthetic enantiomers 1 and 2 showed different biological properties, we investigated the structure activity relationships of bisacetylenic alcohols using 11 synthetic derivatives, and it is clarified that the essential structural unit for antiproliferative activity is the "1-yn-3-ol" on both termini and that there is a minimum chain length that connects the "1-yn-3-ol" moieties.
