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 isolated from clinical samples and biofilms. In a murine catheter-associated urinary tract infection model, DS86760016 treatment resulted in significant eradication of from the kidney, bladder, and catheter without developing drug resistance.

and Activities of DS86760016, a Novel Leucyl-tRNA Synthetase Inhibitor for Gram-Negative Pathogens.

The emergence of multidrug-resistant (MDR) Gram-negative bacilli is a major concern in the treatment of nosocomial infections. Antibacterial agents with novel modes of action can be useful, as these pathogens have become resistant to almost all existing standard-of-care agents. GSK2251052, a leucyl-tRNA synthetase inhibitor, has a novel mode of action against Gram-negative bacteria.

Identification and synthesis of novel inhibitors of mycobacterium ATP synthase.

A non-diaryl quinoline scaffold 6,7-dihydropyrazolo[1,5-a]pyrazin-4-one was identified by screening of diverse set of compounds against M. smegmatis ATP synthase. Herein, we disclose our efforts to develop the structure activity relationship against Mycobacterium tuberculosis (Mtb.

Mode of action of Ranbezolid against staphylococci and structural modeling studies of its interaction with ribosomes.

Oxazolidinones are known to inhibit protein biosynthesis and act against a wide spectrum of gram-positive bacteria. A new investigational oxazolidinone, ranbezolid, inhibited bacterial protein synthesis in Staphylococcus aureus and Staphylococcus epidermidis. In S.

Ciprofloxacin-resistant Neisseria meningitidis, Delhi, India.

Decreased susceptibility of Neisseria meningitidis isolates to ciprofloxacin emerged from an outbreak in Delhi, India. Results of antimicrobial susceptibility testing of the meningococcal isolates to ciprofloxacin and further sequencing of DNA gyrase A quinolone-resistance-determining region confirmed the emergence of ciprofloxacin resistance in the outbreak.
