RNAP-σ interaction-IN-4

RNAP-σ interaction-IN-4 (Compound 3a) is an inhibitor of the RNA polymerase-sigma factor interaction (RNAP-σ) with MIC values against S. pneumoniae and S. aureus of 1 μg/mL and 2 μg/mL, respectively. RNAP-σ interaction-IN-4 exhibits strong bactericidal properties by interfering with the interaction of β′CH−σ and disrupting the transcription of bacteria. RNAP-IN-2 shows significant efficacy in sepsis models. RNAP-σ interaction-IN-4 can be used to study Gram-positive bacterial infections caused by multi-drug resistant strains[1].
