  Novel Hybrid-Type Antimicrobial Agents Targeting the Switch Region of Bacterial RNA Polymerase

  摘要：

  The bacterial RNA polymerase (RNAP) is an ideal target for the development of antimicrobial agents against drug-resistant bacteria. Especially, the switch region within RNAP has been considered as an attractive binding site for drug discovery. Here, we designed and synthesized a series of novel hybrid-type inhibitors of bacterial RNAP. The antimicrobial activities were evaluated using a paper disk diffusion assay, and selected derivatives were tested to determine their MIC values. The hybrid-type antimicrobial agent 29 showed inhibitory activity against Escherichia coli RNAP. The molecular docking study suggested that the RNAP switch region would be the binding site of 29.

  problem, thus discovery of novel and effective antibiotics is urgent. A series of novel hybrids of N-aryl pyrrothine-base α-pyrone hybrids was designed, synthesized and evaluated as bacterial RNA polymerase (RNAP) inhibitors. Among them, compound 13c exhibited potent antibacterial activity against antibiotic-resistant S. aureus with the minimum inhibitory concentration (MIC) in the range of 1-4 μg/mL

  细菌中的抗生素抗性已经成为新兴的公共卫生问题，因此迫切需要发现新型有效的抗生素。设计，合成和评估了一系列新型的N-芳基酪氨酸碱基α-吡喃酮杂种，作为细菌RNA聚合酶（RNAP）抑制剂。其中，化合物13c对抗生素耐药的金黄色葡萄球菌表现出有效的抗菌活性，最小抑制浓度（MIC）在1-4μg/ mL的范围内。此外，化合物13c对大肠杆菌RNAP表现出强的抑制活性，IC50值为16.06μM，对HepG2细胞的细胞毒性为7.04μM。分子对接研究进一步表明，化合物13c与细菌RNAP的开关区域结合。总之，化合物13c是新型细菌RNAP抑制剂，
