Abstract
DNA-encoded chemical library technology (DECL or DEL) has become an important pillar for small-molecule drug discovery. The technology rapidly identifies small-molecule hits for relevant target proteins at low cost and with a high success rate, including ligands for targeted protein degradation (TPD). More recently, the setup of DNA- or peptide nucleic acid (PNA)-encoded chemical libraries based on the simultaneous display of ligand pairs, termed dual-display, allows for more sophisticated applications which will be reviewed herein. Both stable and dynamic dual-display DEL technologies enable innovative affinity-based selection modalities, even on and in cells. Novel methods for a seamless conversion between single- and double-stranded library formats allow for even more versatility. We present the first candidates emerging from dual-display technologies and discuss the future potential of dual-display for drug discovery.

Bioorg Med Chem 2021; 44:116282. [PMID: 34216984 DOI: 10.1016/j.bmc.2021.116282] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Revised: 06/09/2021] [Accepted: 06/16/2021] [Indexed: 11/26/2022]
Abstract
A dual Bcl-XL / Bcl-2 inhibitor was discovered from DNA-encoded libraries using a two steps process. In the first step, DNA was used to pair PNA-encoded fragments exploring > 250 000 combinations. In the second step, a focused library combining the selected fragments with linkers of different lengths and geometries led to the identification of tight binding adducts that were further investigated for their selective target engagement in pull-down assays, for their affinity by SPR, and their selectivity in a cytotoxicity assay. The best compound showed comparable cellular activity to venetoclax, the first-in-class therapeutic targeting Bcl-2.

Abstract
DNA display of PNA-encoded libraries was used to pair fragments containing different phosphotyrosine surrogates with diverse triazoles. Microarray-based screening of the combinatorially paired fragment sets (62,500 combinations) against a prototypical phosphatase, PTP1B, was used to identify the fittest fragments. A focused library (10,000 members) covalently pairing identified fragments with linkers of different length and geometry was synthesized. Screening of the focused library against PTP1B and closely related TCPTP revealed orthogonal inhibitors. The selectivity of the identified inhibitors for PTP1B versus TCPT was confirmed by enzymatic inhibition assay.

Abstract
Peptide nucleic acid (PNA)-encoded chemical libraries along with DNA-encoded libraries have provided a powerful new paradigm for library synthesis and ligand discovery. PNA-encoding stands out for its compatibility with standard solid phase synthesis and the technology has been used to prepare libraries of peptides, heterocycles and glycoconjugates. Different screening formats have now been reported including selection-based and microarray-based methods that have yielded specific ligands against diverse target classes including membrane receptors, lectins and challenging targets such as Hsp70.

Abstract
Identification of selective and synthetically tractable ligands to glycan-binding proteins is important in glycoscience. Carbohydrate arrays have had a tremendous impact on profiling glycan-binding proteins and as analytical tools. We report a highly miniaturized synthetic format to access nucleic-acid-encoded hetero-glycoconjugate libraries with an unprecedented diversity in the combinations of glycans, linkers, and capping groups. Novel information about plant and bacterial lectin specificity was obtained by microarray profiling, and we show that a ligand identified on the array can be converted to a high-affinity soluble ligand by straightforward chemistry.

Abstract
Nucleic acid-encoded libraries are emerging as an attractive and highly miniaturized format for the rapid identification of protein ligands. An important criterion in the synthesis of nucleic acid encoded libraries is the scope of reactions that can be used to introduce molecular diversity and devise divergent pathways for diversity-oriented synthesis (DOS). To date, the protecting group strategies that have been used in peptide nucleic acid (PNA) encoded synthesis (PES) have limited the choice of reactions used in the library synthesis to just a few prototypes. Herein, we describe the preparation of PNA monomers with a protecting group combination (Mtt/Boc) that is orthogonal to Fmoc-based synthesis and compatible with a large palette of reactions that have been productively used in DOS (palladium cross-couplings, metathesis, reductive amination, amidation, heterocycle formation, nucleophilic addition, conjugate additions, Pictet-Spengler cyclization). We incorporate γ-modifications in the PNA backbone that are known to enhance hybridization and solubility. We demonstrate the robustness of this strategy with a library synthesis that is characterized by MALDI MS analysis at every step.
