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.

Abstract:
Death of renal cells is central to the pathophysiology of kidney graft injury and delayed graft function in kidney transplant (KTX). Necroptosis, a recently discovered form of regulated cell death, has emerged as a pivotal event in the development of various kidney disorders, mainly triggered by the activation of receptor-interacting protein kinase 1 (RIPK1). Protein phosphatase 1 regulatory subunit 3G (PPP1R3G) has been identified to work with protein phosphatase 1γ (PP1γ) in kinase activation. However, the role of PPP1R3G in RIPK1 activation and tubular cell death remains unexplored. This st

Abstract:
AbstractS100 proteins are small, typically homodimeric, vertebrate-specific EF-hand proteins that establish Ca2+-dependent protein–protein interactions in the intra- and extracellular environment and are overexpressed in various pathologies. There are about 20 distinct human S100 proteins with numerous potential partner proteins. Here, we used a quantitative holdup assay to measure affinity profiles of most members of the S100 protein family against a library of chemically synthetized foldamers. The profiles allowed us to quantitatively map the binding promiscuity of each member towards the fo
