Abstract :
[en] Antibiotic resistance is an increasingly important global public health issue, as major opportunistic pathogens are evolving toward multidrug- and pan-drug resistance phenotypes. New antibiotics are thus needed to maintain our ability to treat bacterial infections. According to the WHO, carbapenem-resistant Acinetobacter, Enterobactericaeae, and Pseudomonas are the most critical targets for the development of new antibacterial drugs. An automated phenotypic screen was implemented to screen 634 synthetic compounds obtained in-house for both their direct-acting and synergistic activity. Fourteen percent and 10% of the compounds showed growth inhibition against tested Gram-positive and Gram-negative bacteria, respectively. The most active direct-acting compounds showed a broad-spectrum antibacterial activity, including on some multidrug-resistant clinical isolates. In addition, 47 compounds were identified for their ability to potentiate the activity of other antibiotics. Compounds of three different scaffolds (2-quinolones, phenols, and pyrazoles) showed a strong potentiation of colistin, some being able to revert colistin resistance in Acinetobacter baumannii. © 2020 American Chemical Society.
