“…Practically, dual-display DELs permit the discovery of synergistic pairs of ligands, in a fashion comparable to fragment based drug discovery (FBDD). , However, it is necessary to engineer linkers between the binding moieties after selection experiments, as it is the case with FBDD approaches. − While new methodologies have been developed to transition from double-stranded to single-stranded DELs, rendering the libraries more modular and versatile for synthesis and selections, − dual-display DELs enable innovative strategies for affinity-based selections such as affinity maturation of known hits and (photo)cross-linking to biological targets in solution or on cell surfaces . Thanks to its continued optimization, the field of dual-display DELs now offers a panel of options for starting drug discovery projects. ,− …”
