F. Cafieri et al., GLYCOLIPIDS FROM SPONGES .5. A NOVEL TETRAGLYCOSYLATED SPHINGOLIPID FROM THE MARINE SPONGE AGELAS-LONGISSIMA, Gazzetta chimica italiana, 126(11), 1996, pp. 711-717
The polar fractions obtained from the methanolic extract of the marine
sponge Agelas longissima have been analyzed for glycosphingolipids. T
he structure of the novel tetraglycosylated sphingolipid la, containin
g the uncommon beta-fucofuranose, was elucidated by extensive NMR stud
ies of its peracetate derivative and chemical analysis.
