TP0586532 is an experimental antibiotic drug, which acts as a potent and selective inhibitor of the bacterial enzyme UDP-3-O-acyl-N-acetylglucosamine deacetylase (LpxC). This enzyme is important for the production of Lipid A, a key component of the cell membrane of Gram-negative bacteria. Previous inhibitors of LpxC have failed to progress into clinical trials in humans, mostly because of off-target cardiovascular toxicity, so TP0586532 was based on a different structural class which is hoped to reduce this risk. In animal studies it shows activity against carbapenem-resistant Klebsiella pneumoniae but has not yet progressed into human trials.
