DS86760016
Catalog No. T39296 CAS
1853176-89-2
DS86760016 is a highly effective inhibitor of leucyl-tRNA synthetase (LeuRS), demonstrating potent activity against multidrug-resistant (MDR) Gram-negative bacteria including Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa. Notably, DS86760016 effectively inhibits LeuRS enzymes derived from Escherichia coli, Pseudomonas aeruginosa, and Acinetobacter baumannii, exhibiting IC50 values of 0.38 μM, 0.62 μM, and 0.16 μM, respectively.

In vitro
DS86760016 demonstrates inhibitory effects on certain Gram-negative bacteria, exhibiting Minimum Inhibitory Concentrations (MICs) between 0.25 to 2 μg/ml. Conversely, its efficacy against Gram-positive bacteria is significantly lower, with an MIC >32 μg/ml. This compound is notably active against both susceptible and Multi-Drug Resistant (MDR) strains of P. aeruginosa, E. coli, and K. pneumoniae, achieving an MIC90 of 2 μg/ml[1].
In vivo
DS86760016, administered subcutaneously at doses ranging from 7.5 to 220 mg/kg every six hours for seven days, demonstrates moderate spontaneous resistance (FSR)[1]. Its pharmacokinetic (PK) profile has been evaluated in the plasma of mice, rats, monkeys, and dogs following intravenous (i.v.) administration, revealing lower plasma clearance rates (CLp) of 11, 29, 5.6, and 4.5 ml/min/kg, respectively. Correspondingly, the plasma half-lives (t1/2) of DS86760016 are 1.9 hours in mice, 1.5 hours in rats, 8.6 hours in monkeys, and 8.3 hours in dogs. These lower clearance rates result in higher plasma exposures, with dose-normalized areas under the curve after i.v. administration (DNAUC IVs) being 1.5, 0.6, 3.7, and 3.0 μg h kg/ml/mg, respectively[1]. In an animal model utilizing immunocompetent female Swiss Webster mice for a urinary tract infection (UTI) model[1], DS86760016 treatment showed that bacteria resistant to it were present in a few animals after one day at doses of 7.5 and 30 mg/kg every six hours; however, no resistance was observed at these doses after seven days. Notably, no resistance was detected at the highest dose of 220 mg/kg every six hours.
