of 24 newly synthesized dibenzoxazepines identified a smallmolecule compound, SW14, with potent inhibitory activity against intracellular multidrug-resistant and fluoroquinolone-resistant strains of S. typhimurium in macrophages and epithelial cells. Moreover, intra-macrophagic Salmonella typhi, Yersinia enterocolitica, and Listeriamonocytogenes and methicillin-resistant Staphylococcus aureus are also
