ETX0462

ETX0462 is a novel, first-in-class, diazabicyclooctane with antimicrobial activity against multidrug-resistant (MDR) Gram-negative and biothreat pathogens including, P. aeruginosa, K. pneumoniae, S. maltophilia, E. coli, B. anthracis, Y. pestis, F. tularensis and Burkholderia spp. Similar to β-lactam antibiotics, ETX0462 inhibits penicillin-binding proteins which are essential for bacterial cell wall biosynthesis, however, unlike β-lactam antibiotics, ETX0462 is unaffected by β-lactamase mediated resistance.
