Summary: The World Health Organization has identified the threat posed by drug-resistant gram-negative bacteria as a global health priority. However, the current pipeline for new antibiotics is inadequate; antibacterials with novel mechanisms of action are urgently needed. The authors of this manuscript aimed to identify new chemical entities with activity against multidrug-resistant strains of priority pathogens Klebsiella pneumoniae and Acinetobacter baumannii. They  implemented and validated a primary whole cell screening methodology to test new chemical matter from the proprietary compound collections of three pharmaceutical companies. Two new scaffolds with activity against multidrug-resistant A. baumannii were identified.  This study provides evidence that a screening strategy starting with multidrug-resistant bacteria can be useful for screening new chemical matter.
