Abruptoside A, A novel glycolipid from the Kenyan soft coral Sinularia abrupta

Abstract

Two homologue glycolipids, abruptosides A and B were isolated from the Kenyan soft coral Sinularia abrupta. Their structures are composed of a tetrasubstituted diarabinosyl carbohydrate carrying two acetates, a 3-hydroxybutanoate and a 4Z-dodec-4-en-1-ol or 4Z-tridec-4-en-1-ol group. The structures were determined by MS and 1D and 2D NMR spectroscopy.
