The main objectives of this team are the design and the elaboration of new original, active and selective biomolecules with potential applications in therapeutics. This lies on the development of new templates (new privileged structures, bioavailable peptides or proteins, artificial folded structures) and new concepts (new type of delivery system for cellular uptake and BBB permeation, conception of foldamers) for drugs discovery. To achieve the construction of these new molecular systems and to analyze them at the structural level or at the quantification level in complex medium (case of cellular uptake measurement), we develop new methodologies which include chemistry on soluble and solid supports, chemistry under microwaves irradiation, methodology of peptide synthesis, protein analysis, etc. Peptide hormones including neuropeptides of the gastrointestinal tract, G-Protein Coupled Receptors (GPCR) ligands, i.e. gastrin, cholecystokinin, bombesin, neurotensin, ghrelin and enzymes including β-Secretases, Aspartyl-Proteases, Seryl-Proteases constituted the major targets of this team which provided to the scientific community new tools for diagnosis and the understanding of pathological disorders.
