Discovery of Novel Inhibitors of LpxC Displaying Potent in Vitro Activity against Gram-Negative Bacteria.
J.Med.Chem., 63:66-87, 2020

PubMed Abstract: UDP-3--(()-3-hydroxymyristoyl)--glucosamine deacetylase (LpxC) is as an attractive target for the discovery and development of novel antibacterial drugs to address the critical medical need created by multidrug resistant Gram-negative bacteria. By using a scaffold hopping approach on a known family of methylsulfone hydroxamate LpxC inhibitors, several hit series eliciting potent antibacterial activities against Enterobacteriaceae and were identified. Subsequent hit-to-lead optimization, using cocrystal structures of inhibitors bound to LpxC as guides, resulted in the discovery of multiple chemical series based on (i) isoindolin-1-ones, (ii) 4,5-dihydro-6-thieno[2,3-]pyrrol-6-ones, and (iii) 1,2-dihydro-3-pyrrolo[1,2-]imidazole-3-ones. Synthetic methods, antibacterial activities and relative binding affinities, as well as physicochemical properties that allowed compound prioritization are presented. Finally, in vivo properties of lead molecules which belong to the most promising pyrrolo-imidazolone series, such as , are discussed.
