Bacterial RNA polymerase (RNAP) is a validated drug target for broad-spectrum antibiotics, and its “switch region” is considered as the promising binding site for novel antibiotics. Based on the core scaffold of dithiolopyrrolone, a series of N-aryl pyrrothine derivatives was designed, synthesized, and evaluated for their antibacterial activity. Compounds generally displayed more active against Gram-positive bacteria, but less against Gram-negative bacteria. Among them, compound 6e exhibited moderate antibacterial activity against clinical isolates of rifampin-resistant Staphylococcus aureus with minimum inhibition concentration value of 1–2?μg/ml and inhibited Escherichia coli RNAP with IC50 value of 12.0?±?0.9?μM. In addition, compound 6e showed certain degree of cytotoxicity against HepG2 and LO2 cells. Furthermore, molecular docking studies suggested that compound 6e might interact with the switch region of bacterial RNAP in a similar conformation to myxopyronin A. Together, the N-aryl pyrrothine scaffold is a promising lead for discovery of antibacterial drugs acting against bacterial RNAP.
