Australian Journal of Chemistry
48(11) 1899 - 1902
A new sesterterpene tetronic acid (5) exhibiting antimicrobial activity has been isolated from an Australian marine sponge, Psammocinia sp., and its structure secured by detailed spectroscopic analysis. The tetronic acid (5) possesses almost identical spectroscopic characteristics to, and is a structural isomer of, the known marine natural product (6) previously reported from an Australian sponge.
