With the aim to find new protein-protein inhibitors, a three part methodology was applied to oligophenylpyridines. Theoretical ring twist angle predictions have been validated by X-ray diffraction and molecular dynamics simulations with NMR constraints. Careful choice of substituent and nitrogen positions in oligophenylpyridyl foldamer units opens the way(More)
Protein-protein interactions are central to many biological processes, from intracellular communication to cytoskeleton assembly, and therefore represent an important class of targets for new therapeutics. The most common secondary structure in natural proteins is an α-helix. Small molecules seem to be attractive candidates for stabilizing or disrupting(More)
Starting from nonpeptide agonists and antagonists of human urotensin-II (hU-II), several pharmacophores were designed and compared to the structure of hU-II. NMR and dynamic studies were realized on hU-II and urotensin-II-related peptide to check the conformation flexibilities of these peptides and the relationships between their potential 3D structures and(More)
