secondary structural elements such as helices, turns, and sheets. Many of these functions are affected by a small number of key structural element, protein–proteininteractions. Their mimicry by peptide and non-peptide scaffolds has become a major focus of contemporary research. This paper examines oligomeric system as new foldamers, which either reproduce the local topography of the helix, or project

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 alpha-helix. Small molecules seem to be attractive candidates for stabilizing or disrupting protein protein interactions based on alpha-helices. In our study, we assessed the ability of oligopyridyl scaffolds to mimic the alpha-helical twist. The theoretical as well as experimental studies (X-ray diffraction and NMR) on conformations of bipyridines in the function of substituent and pyridine nitrogen positions were carried out. Furthermore, the experimental techniques showed that the conformations observed in bipyridines are maintained within a longer oligopyridyl scaffold (quaterpyridines). The alignment of the synthesized quaterpyridine with two methyl substituents showed that it is an alpha-helix foldamer; their methyl groups overlap very well with side chain positions, i and i + 3, of an ideal alpha-helix.
