primary concern. In this context, EPIs may restore life to old drugs. In the present work, the EPI activity of the COX-2 inhibitor celecoxib was confirmed and a new class of pyrazolo[4,3-c][1,2]benzothiazine 5,5-dioxide analogues acting as inhibitors of the Staphylococcus aureus NorA multidrug efflux pump was identified.
临床上普遍使用的对抗菌剂的耐药性不断提高,以及对多种药物具有耐药性的菌株的生长表明,新治疗方法的开发应成为首要关注的问题。在这种情况下,EPI可能会使旧药恢复生命。在目前的工作中,确认了COX-2抑制剂塞来昔布的EPI活性,并使用了新型的吡唑并[4,3- c ] [1,2]苯并噻嗪5,5-二氧化物类似物作为金黄色葡萄球菌NorA的抑制剂。确定了多药外排泵。
