NMR‐Guided Fragment‐Based Approach for the Design of tRNALys3 Ligands

Two in one: Two ligands for tRNALys3 that were identified from a compound library by flow-injection NMR spectroscopic screening and found to have millimolar dissociation constants (on the left in the picture) inspired the fragment-based synthesis of a new family of ligands with the general structural features of both initial compounds. Ligand 1 of this family is a selective D-stem binder of tRNALys3 with a micromolar Kd value.
