Bacterial biofilms and quorum sensing

Metallo-β-lactamases represent an emerging clinical threat due to their ability to render ineffective an entire class of antibiotics. Accordingly, this family of enzymes has been suggested as an attractive target for drug design. Progress toward developing effective inhibitors as well as the development of reporter substrates is reviewed. Inhibitors are classified into six classes and known binding interactions with metallo-β-lactamases are summarized. The development of chromogenic and fluorogenic reporter substrates is also reviewed with respect to current and prospective applications to future inhibitor and diagnostic discovery, mechanistic studies, and biological imaging. Despite progress in molecular probe development, the sequence and structural diversity within the metallo-β-lactamase family continue to present substantial hurdles for rational ligand design.
