Research Abstract |
New linear polyacetylene compounds designated petroacetylene and bromotheoynic acid have been isolated from the marine sponge Petrosia solida Hoshino 1981 and Theonella swinhoei, respectively, collected off the coast of Kagoshima Prefecture, Japan. The structures were elucidated on the basis of spectroscopic data and chemical means. We have evaluated the effects of the new polyacetylenes on development and hatching of echinoderm embryos.
