Popis: The development of peptide stapling techniques to stabilise alpha-helical secondary structure motifs of peptides led to the design of modulators of protein-protein interactions, which had been considered undruggable for a long time. We disclose a novel approach towards peptide stapling utilising macrocyclisation by late-stage Suzuki-Miyaura cross-coupling of bromotryptophan-containing peptides of the catenin-binding domain of axin. Optimisation of the linker length in order to find a compromise between both sufficient linker rigidity and flexibility resulted in a peptide with an increased alpha-helicity and enhanced binding affinity to its native binding partner beta-catenin. An increased proteolytic stability against proteinase K has been demonstrated.
