drug-resistant Gram + ve and Gram-ve pathogens at concentrations similar or lower than levofloxacin. Microbiology studies revealed that the plausible target of the pyrrole derivatives is the bacterial DNA gyrase, with the pyrrole derivatives displaying similar inhibitory activity to levofloxacin against the wild type enzyme and retaining activity against the fluoroquinolone-resistant enzyme.
抗生素耐药性是全球范围内的主要威胁。革兰氏阳性和革兰氏阴性机会病原体对所有已知药物均产生耐药性,这主要是由于这些药物的过度使用和滥用以及制药行业缺乏新的抗生素开发。迫切需要发现在结构上没有创新性的抗菌剂。这项工作描述了对一系列ESKAPE细菌具有活性的新型1,5-二苯基吡咯化合物的鉴定,合成和生物学评估。新化合物在与左氧氟沙星相似或低于左氧氟沙星的浓度下,对野生型和抗药性革兰氏阳性和革兰氏阴性病原体均显示出高活性。
