NMR-Guided Fragment-Based Approach for the Design of AAC(6′)-Ib Ligands

Reverse n.O.e. pumping in the detection and optimisation of ligands: Ligand-observed NMR experiments have been used to drive the detection and optimisation of non-aminoglycosidic ligands for AAC(6′)Ib, one of the most clinically important resistance enzymes to aminoglycosides. This fragment-based approach has been conducted without any need for NMR structural assignment of the target, and has been validated by the preparation of a bisubstrate inhibitor.
