Popis: Increasing resistance of bacteria to antibiotics is a serious global challenge and there is a need to unlock the potential of novel antibacterial targets. One such target is the essential prokaryotic endoribonuclease RNase E. Using a combination of in silico high-throughput screening and in vitro validation we have identified three novel small molecule inhibitors of RNase E that are active against RNase E from Escherichia coli, Francisella tularensis and Acinetobacter baumannii. Two of the inhibitors are non-natural small molecules that could be suitable as lead compounds for the development of broad-spectrum antibiotics targeting RNase E. The third small molecule inhibitor is glucosamine-6-phosphate, a precursor of bacterial cell envelope peptidoglycans and lipopolysaccharides, hinting at a novel metabolite-mediated mechanism of regulation of RNase E.
Highlights • RNase E, an essential bacterial endoribonuclease, is a potential antibacterial target. • Three novel small molecule inhibitors of RNase E are identified. • Each inhibitor is active against RNase E from E. coli, F. tularensis and A. baumannii. • Two, as non-natural compounds, are suitable lead compounds for antibiotic development. • One, a metabolite, is a potential novel regulator of RNase E.
