LPC-233
LPC-233 is an experimental antibiotic drug. It acts as a potent and selective inhibitor of the bacterial enzyme UDP-3-O-acyl-N-acetylglucosamine deacetylase, which is important for the production of Lipid A, a key component of the cell membrane of Gram-negative bacteria. Various inhibitors of LpxC have been developed but none have yet progressed into clinical trials in humans, mostly because of off-target cardiovascular toxicity. LPC-233 is one of the most advanced drugs of this type in preclinical testing, showing activity against several pathogens of concern such as multidrug-resistant Pseudomonas aeruginosa and carbapenem resistant Enterobacter strains, and with no cardiovascular toxicity evident in testing on mice and dogs.
