Freedom to merge: A combination of crystal structure examination and in silico predictions made it possible to overcome the conformational limitations of fragmentmerging and escape the internal strain in a series of weakly binding mergedfragments that target M. tuberculosisCYP121. The insights attained provide a new perspective and guide for prioritizing synthetic efforts toward fragmentmerging in future

efficiency of structural motifs to be assessed, the identification of more LE scaffolds for optimization and highlighted binding affinity hotspots. Structure-guided addition of a metal-binding pharmacophore onto LE retrofragment scaffolds produced low nanomolar (KD = 15 nM) CYP121 ligands. Elaboration of these compounds to targetbinding hotspots in the distal activesite afforded compounds with excellent
