| + | [https://www.uniprot.org/uniprot/DYR1A_HUMAN DYR1A_HUMAN] Defects in DYRK1A are the cause of mental retardation autosomal dominant type 7 (MRD7) [MIM:[https://omim.org/entry/614104 614104]. A disease characterized by primary microcephaly, severe mental retardation without speech, anxious autistic behavior, and dysmorphic features, including bitemporal narrowing, deep-set eyes, large simple ears, and a pointed nasal tip. Mental retardation is characterized by significantly below average general intellectual functioning associated with impairments in adaptative behavior and manifested during the developmental period.<ref>PMID:21294719</ref> | ||

| + | We conceived the Halogen-Enriched Fragment Library (HEFLib) to investigate the potential of halogen bonds in the early stages of drug discovery. As the number of competitive interactions increases with ligand size, we reasoned that a binding mode relying on halogen bonding is more likely for fragments than highly decorated molecules. Thus, fragments could feature unexplored binding modes. We screened the HEFLib against the human kinase DYRK1a and verified micromolar binding fragments via isothermal titration calorimetry (ITC). The crystal structure of one fragment revealed a noncanonical binding mode, despite the fragment's classical hinge binding motif. In addition, the fragment occupies a secondary binding site. Both binding modes feature a halogen bond, which we evaluated by ab initio calculations. Structure-affinity relationship (SAR) from a set of analogues improves the affinity, provides a promising fragment-growth vector, and highlights the benefits and applicability of halogen bonds in early lead development. | ||
