Abstract
The structure of the title compound, (+)-7S-hydroxyxestospongin A was solved by single-crystal X-ray diffraction analysis and the absolute stereochemistry obtained by analysis of the derived R and S Mosher's esters. The absolute configuration of xestospongin D was determined for the first time by analysis of anomalous scattering from the X-ray crystal diffraction data set. Xestospongins A, C, and D, araguspongine C, and demethylxestospongin B exhibited modest antifungal activity (MIC 30-100 g/mL) against various fluconazole-resistant Candida spp., but 7S-hydroxyxestospongin A was inactive.
