V. Costantino et al., GLYCOLIPIDS FROM SPONGES .3. GLYCOSYL CERAMIDES FROM THE MARINE SPONGE AGELAS-CONIFERA, Liebigs Annalen, (12), 1995, pp. 2133-2136
The glycosphingolipid (GSL) composition of the marine sponge Agelas co
nifera was investigated. In addition to three GSLs previous isolated f
rom Agelas clathrodes (2a-4a), the novel alpha-glycosylceramide 1a was
isolated as a major componentof the GSL mixture, and its structure wa
s elucidated by extensive NMR studies and by chemical analysis.
