Abstract

The design, syntheses and Antibacterial evaluation of sulfone analogues of previously disclosed Metallo-β-lactamase inhibitors (MBLis) are described. The novel derivatives were overall more effective in gram-negative Bacterial cell-based assays when combined with imipenem and relebactam. The major contributors to the improved anti-bacterial activity are enhanced enzyme-inhibitor interactions and reduced Bacterial cell efflux monitored via an efflux assay involving isogenic Pseudomonas aeruginosa efflux + and efflux - tool strains.
