ABSTRACT

Sulfur fluoride exchange (SuFEx), a next generation of click chemistry, opens an avenue for drug discovery. We report here the discovery and structure-activity relationship studies of a series of arylfluorosulfates, synthesized via SuFEx, as antibacterial agents. Arylfluorosulfates 3, 81, and 101 showed potency to overcome multidrug resistance and were not susceptible to the generation of resistance. They exhibited rapid bactericidal potency and selectively killed gram-positive bacterial strains. These compounds also exhibited the ability to disrupt established bacterial biofilm and kill persisters derived from biofilm. Furthermore, arylfluorosulfate 3 had a synergistic effect with streptomycin and gentamicin. In addition, their anti-MRSA potency was evaluated and determined by the Caenorhabditis elegans model.
