In this context, supramolecular helicates have shown high selectivity and binding affinity for 3WJs, but their use in this field is hampered by the lack of synthetic versatility and a general strategy to their enantioselective synthesis. In this thesis, we describe the stereoselective self-assembly of helicates derived from peptide ligands equipped with 2,2’-bipyridine coordinating residues, as well as the implementation of a new strategy that relies on the cooperative 3WJ-binding mechanism of natural proteins, to yield new systems with selective 3WJs recognition properties.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/DNA structuresdrugspeptide ligandsstereoselective synthesis of dinuclear Cu(II)230223 Ácidos nucleicos230307 Compuestos de coordinacióndoctoral thesisopen access
