Optimization of fragment hits toward high-affinity lead compounds is a crucial aspect of fragment-based drug discovery (FBDD). In the current study, we have successfully optimized a fragment by growing into a ligand-inducible subpocket of the bindingsite of acetylcholine-binding protein (AChBP). This protein is a soluble homologue of the ligandbinding domain (LBD) of Cys-loop receptors. The fragment
