title: Three dolabellanes and a macrolide from the sponge Dysidea sp. from Palau.
abstract: A specimen of Dysidea sp. from Palau contained three new dolabellane diterpenes 1-3 and an unstable 14-membered macrolide, arenolide (4), which showed modest cytotoxicity. From a chemotaxonomic viewpoint, these metabolites are so unusual that we discuss their possible origin.
