DS86760016 is a potent leucyl-tRNA synthetase (LeuRS) inhibitor with activity against multidrug-resistant (MDR) Gram-negative bacteria, such as Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa. DS86760016 inhibits LeuRS enzymes from Escherichia coli, Pseudomonas aeruginosa, and Acinetobacter baumannii, with IC50s of 0.38, 0.62, and 0.16 μM, respectively[1][2].
DS86760016 inhibits some Gram-negative bacteria with an MICs ranging from 0.25 to 2 μg/ml. The MIC of DS86760016 against Gram-positive bacteria is >32 μg/ml. DS86760016 is active against both susceptible and these MDR P. aeruginosa, E. coli, and K. pneumoniae strains, with an MIC90 of 2 μg/ml[1].
DS86760016 (7.5-220 mg/kg; s.c.; q6h for 7 days) shows moderate spontaneous resistance (FSR)[1].The pharmacokinetic (PK) parameters of DS86760016 in mouse, rat, monkey, and dog plasma by the intravenous (i.v.) route are test. DS86760016 shows lower intravenous plasma clearances (CLp) of 11, 29, 5.6, and 4.5 ml/min/kg in mouse, rat, monkey, and dog plasma, respectively. The plasma half-lives (t1/2) for DS86760016 are 1.9, 1.5, 8.6, and 8.3 h in mice, rats, monkeys, and dogs, respectively. The lower plasma clearance resulted in higher plasma exposures for DS86760016, with dose-normalized areas under the curve after i.v. administration (DNAUCIVs) of 1.5, 0.6, 3.7, and 3.0 μg h kg/ml/mg in mice, rats, monkeys, and dogs, respectively[1].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )
Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL saline, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
