  • PubMed Abstract: 

    We report 17 small-molecule ligands that compete with N6 -methyladenosine (m 6 A) for binding to the m 6 A-reader domain of YTHDF2 (YT521-B homology domain family 2). We determined their binding mode at high resolution by X-ray crystallography and quantified their affinity by a fluorescence-based binding assay. 6-Cyclopropyluracil and a pyrazolopyrimidine derivative have favorable ligand efficiencies of 0.47 and 0.38 kcal mol -1 per non-hydrogen atom, respectively. They represent useful starting points for hit optimization.
