Discovery and Optimization of nTZDpa as an Antibiotic Effective Against Bacterial Persisters.

Conventional antibiotics are not effective in treating infections caused by drug-resistant or persistent nongrowing bacteria, creating a dire need for the development of new antibiotics. We report that the small molecule nTZDpa, previously characterized as a nonthiazolidinedione peroxisome proliferator-activated receptor gamma partial agonist, kills both growing and persistent Staphylococcus aureus cells by lipid bilayer disruption.
