In-house research projects

These projects have evolved as a result of interactions with glycobiologists in academic groups, mainly at Sahlgren's Academy, Göteborg University.
We have been working on docking the Norovirus surface protein with natural carbohydrate ligands as a prelude to structure-based design of adhesion inhibitors. In these projects we have been doing the modelling while our collaborators have done the wet lab tests. Part of that work has been directed against the design of a treatment for winter-vomiting disease.

We have supported several PhD projects regarding conformational analyses of carbohydrates and protein-ligand docking (see ref. 1-10).

We are associate partners of the Marie-Curie network "Glycopar", see www.glycopar.eu
