The group focuses on design, chemo- or biosynthesis of compounds with biological or (potential) medicinal applications and interaction with their receptors. Insights thus obtained could lead to new bio-active compounds, new approaches for the treatment of still incurable diseases and new approaches to unsatisfactory treatments. We are interested in answering questions related to understanding as well as influencing peptide-protein, carbohydrate-protein and protein-protein interactions that underlie e.g. infection, immunological and neurological disorders. Especially modified peptides and peptidomimetics as well as carbohydrates are synthesized and studied. The research program is part of the Utrecht Institute for Pharmaceutical Sciences, as well as the Bijvoet Center for Biomolecular Research.
