|Title:||First-in-class inhibitors targeting the interaction between bacterial RNA polymerase and sigma initiation factor affect the viability and toxin release of streptococcus pneumoniae||Authors:||Ye, J

The protein-protein interaction between bacterial RNA polymerase (RNAP) and the housekeeping sigma initiation factor is essential to transcription and bacterial viability. It also presents a potential target for antimicrobial discovery, for which a hit compound (C3) was previously identified from a pharmacophore modelbased in silico screen. In this study, the hit compound was experimentally assessed with some rationally designed derivatives for the antimicrobial activities, in particular against Streptococcus pneumoniae and other pathogens. One compound, C3-005, shows dramatically improved activity against pneumococci compared to C3. C3-005 also attenuates S. pneumoniae toxin production more strongly than existing classes of antibiotics tested. Here we demonstrate a newly validated antimicrobial agent to address an overlooked target in the hit-to-lead process, which may pave the way for further antimicrobial development.||URI:||http://hdl.handle.net/10397/81554||ISSN:||1420-3049||DOI:||10.3390/molecules24162902||Rights:||© 2019 by the authors.
