Eradicating Bacterial Persisters with Combinations of Strongly and Weakly Metabolism-Dependent Antibiotics

Cell Chem Biol. 2020 Dec 17;27(12):1544-1552.e3. doi: 10.1016/j.chembiol.2020.08.015. Epub 2020 Sep 10.

Abstract

The vast majority of bactericidal antibiotics display poor efficacy against bacterial persisters, cells that are in a metabolically repressed state. Molecules that retain their bactericidal functions against such bacteria often display toxicity to human cells, which limits treatment options for infections caused by persisters. Here, we leverage insight into metabolism-dependent bactericidal antibiotic efficacy to design antibiotic combinations that sterilize both metabolically active and persister cells, while minimizing the antibiotic concentrations required. These rationally designed antibiotic combinations have the potential to improve treatments for chronic and recurrent infections.

Keywords: antibiotic combinations; antibiotics; bacterial persisters; metabolism.
