The chemical investigation of marine invertebrates from the deep Northeastern Atlantic revealed new lipoglycotripeptides named characellides isolated from the tetractinellid sponge Characella pachastrelloides. This new family of natural products features a central tripeptide linked to a rare sugar unit and a long alkyl chain ending with a 2,3-dimethyltetrahydropyran. The configurations of all 13 chiral centers were determined by extensive use of NMR data and circular dichroism spectra combined with calculations.
