Dear Bill,
Following your suggestion, here is a list of the most recently published papers on the chemistry of opisthobranchs by our group.

We have some other manuscripts in revision. I'll let you know when these articles are published.

  • W. Zhang, M. Gavagnin, Y.-W. Guo, E. Mollo, M. T. Ghiselin and G. Cimino. (2007) Terpenoid metabolites of the nudibranch Hexabranchus sanguineus from the South China Sea. Tetrahedron, 63: 4725-4729.
  • M. Gavagnin, M. Carbone, P. Amodeo, E. Mollo, R. M. Vitale, V. Roussis and G. Cimino. (2007) Structure and absolute stereochemistry of syphonoside: a unique macrocyclic glycoterpenoid from marine organisms.
     J. Org. Chem., 72: 5625-5630.
  • E. Manzo, M. Gavagnin, G. Bifulco, P. Cimino, S. Di Micco, M. L. Ciavatta, Y.-W. Guo, and G. Cimino. (2007) Aplysiols A and B, squalene-derived polyethers from the mantle of the sea hare Aplysia dactylomelaTetrahedron, 63: 9970-9978.

Thanks Margherita,

The study of secondary metabolites in opisthobranchs is certainly a powerful tool linking particular species to their food items. Your paper (Gavagnin et al., 2007) sugetsing that the sea hare Syphonota geographica feeds on the sea grass Halophila stipulacea is particularly interesting because sea hares are usually thought to feed on algae rather than sea grasses.

Best wishes,
Bill Rudman
