Discovery of a Tricyclic β-Lactam as a Potent Antimicrobial Agent against Carbapenem-Resistant Enterobacterales, Including Strains with Reduced Membrane Permeability and Four-Amino Acid Insertion into Penicillin-Binding Protein 3: Structure–Activity-Relationships and <i>In Vitro</i> and <i>In Vivo</i> Activities
clinical isolates with resistance mechanisms other than β-lactamase production. These mechanisms were the reduction of outer membrane permeability with the production of β-lactamases and the insertion of four amino acids into penicillin-binding protein 3. Here, we report the discovery of a potent compound that overcomes these resistance mechanisms by the conversion of the alkoxyimino moiety of the aminothiazole
