DS86760016, a Leucyl-tRNA Synthetase Inhibitor with Activity against Pseudomonas aeruginosa.

DS86760016 is a new leucyl-tRNA-synthetase inhibitor at the preclinical development stage. DS86760016 showed potent activity against extended-spectrum multidrug-resistant Pseudomonas aeruginosa isolated from clinical samples and in vitro biofilms. In a murine catheter-associated urinary tract infection model, DS86760016 treatment resulted in significant eradication of P. aeruginosa from the kidney, bladder, and catheter without developing drug resistance. Our data suggest that DS86760016 has the potential to act as a new drug for the treatment of Pseudomonas infections.
