Supramolecular polymers have shown to be powerful scaffolds for tissue engineering applications. Supramolecular biomaterials functionalized with ureidopyrimidinone (UPy) moieties, which dimerize via quadruple hydrogen-bond formation, are eminently suitable for this purpose. The conjugation of the UPy moiety to biologically active peptides ensures adequate integration into the supramolecular UPy polymer matrix. The structural complexity of UPy-peptide conjugates makes their synthesis challenging and until recently low yielding, thus restricted the access to structurally diverse derivatives. Here we report optimization studies of a convergent solid-phase based synthesis of UPy-modified peptide..
