Abstract

Spectroscopy-guided chemical analysis of a marine sponge from the genus Plakortis, collected in Tonga, yielded seven new metabolites of polyketide origin, lehualides E− K (5− 11), four of which incorporate various sulfur functionalities. The structures of compounds 5− 11 were elucidated by interpretation of spectroscopic data and spectral comparison with model compounds. The biological activities of compounds 6− 9 were investigated against ...
