Abstract:
A “foldamer” is an artificial oligomeric molecule with a regular secondary or tertiary structure consisting of various building blocks. A “stapled peptide” is a peptide with stabilized secondary structures, in particular, helical structures by intramolecular covalent side-chain cross-linking. Helical foldamers and stapled peptides are potential drug candidates that can target protein-protein interactions because they enable multipoint molecular recognition, which is difficult to achieve with low-molecular-weight compounds. This mini-review describes a variety of peptide-based foldamers and sta

Abstract:
Foldamers are complex molecular scaffolds that mimic the form and function of biological molecules and are composed of simple repeating units.[1] Their potential applications include stereoselective and efficient organic catalysis mimicking the properties of enzymes, as well as bioreceptor mimics for new foldamer-protein interactions which could provide interesting possibilities for the medical industry.[2] In our previous studies we have investigated the folding properties of two oligoamides.[3] As the next step we prepared a series of aromatic oligoamide foldamers with several folding units

Abstract:
Current methods for proteomimetic engineering rely on structure‐based design. Here we describe a design strategy that allows the construction of proteomimetics against challenging targets without a priori characterization of the target surface. Our approach relies on (i) a 100‐membered photoreactive foldamer library, the members of which act as local surface mimetics, and (ii) the subsequent affinity maturation of the primary hits using systems chemistry. Two surface‐oriented proteinogenic side chains drove the interactions between the short helical foldamer fragments and the proteins. Diaziri

Abstract:
Expanding the chemical diversity of peptide macrocycle libraries for display selection is desirable to improve their potential at binding biomolecular targets. We now have implemented a considerable expansion through a large aromatic helical foldamer inclusion. A helical aromatic foldamer was identified that undergoes flexizyme‐mediated tRNA acylation and is capable of initiating ribosomal translation with yields sufficiently high to perform an mRNA display selection of macrocyclic foldamer‐peptide hybrids. A hybrid macrocyle nanomolar binder to the C‐lobe of the E6AP HECT domain was selected

Le terme foldamère désigne tout oligomère capable de se replier en une structure conformationnellement stable en solution. Parmi eux, les foldamères peptidiques semblent particulièrement intéressants pour répondre à plusieurs défis rencontrés avec les peptides en chimie médicinale, tels que leur trop grande flexibilité et leur faible stabilité in vivo. Le caractère structuré des foldamères peut ainsi s’avérer être un atout dans le développement de nouveaux peptides d’intérêt biologique interagissant avec des protéines ou des membranes (Peptides de Pénétration Cellulaire, CPPs ou Peptides AntiM

Abstract:
Les interactions protéine - protéine sont au centre de nombreux processus biologiques, et représentent des cibles thérapeutiques pertinentes pour le traitement de certaines maladies. La conception de molécules antagonistes visant à inhiber ces interactions requiert la reconnaissance spécifique d’une des surfaces protéiques impliquées. Les foldamères de type oligoamides de quinoline constituent de bons candidats. Leur production et leur fonctionnalisation sont relativement aisées. Ils adoptent des structures hélicoïdales semblables à celles rencontrées dans les protéines. Grâce à différentes te
