title: Hamigerols A and B, unprecedented polysulfate sterol dimers from the Mediterranean sponge Hamigera hamigera.
abstract: Two novel polysulfate sterol dimers, hamigerols A (1) and B (2), have been isolated from the Mediterranean sponge Hamigera hamigera. Their structures and stereochemistry have been assigned from the analysis of spectroscopic data.
