Structural study of phenyl boronic acid derivatives as AmpC β-lactamase inhibitors

A small set of boronic acids acting as low nanomolar inhibitors of AmpC β-lactamase were designed and synthesized in the effort to improve affinity, pharmacokinetic properties, and to provide a valid lead compound. X-ray crystallography revealed the binary complex of the best inhibitor bound to the enzyme, highlighting possibilities for its further rational derivatization and chemical optimization.
