Discovery of a First-in-Class Small-Molecule Ligand for WDR91 Using DNA-Encoded Chemical Library Selection Followed by Machine Learning. J.Med.Chem., 66:16051-16061, 2023 Cited by PubMed Abstract: WD40 repeat-containing protein 91 (WDR91) regulates early-to-late endosome conversion and plays vital roles in endosome fusion, recycling, and transport. WDR91 was recently identified as a potential host factor for viral infection. We employed DNA-encoded chemical library (DEL) selection against the WDR domain of WDR91, followed by machine learning to predict ligands from the synthetically accessible Enamine REAL database. Screening of predicted compounds identified a WDR91 selective compound , with a of 6 ± 2 μM by surface plasmon resonance. The co-crystal structure confirmed the binding of to the WDR91 side pocket, in proximity to cysteine 487, which led to the discovery of covalent analogues and . The covalent adduct formation for and was confirmed by intact mass liquid chromatography-mass spectrometry. The discovery of , , and , accompanying structure-activity relationship, and the co-crystal structures provide valuable insights for designing potent and selective chemical tools against WDR91 to evaluate its therapeutic potential.
