Densazalin, a polycyclic alkaloid, was isolated from the marine sponge <i>Haliclona densaspicula</i> collected in Korea. The complete structure of the compound was determined by spectroscopic methods, including 1D and 2D nuclear magnetic resonance techniques, high-resolution mass spectrometry, and comparison of the calculated and measured electronic circular dichroism spectra. Densazalin possesses a unique 5,11-diazatricyclo[7.3.1.0<sup>2,7</sup>]tridecan-2,4,6-triene moiety, which is connected ...[more]
