hospital- and community-acquired infections. The discovery and optimization of this novel class of antibacterials by the use of structure-guided design, modeling, and structure-activity relationships are described. Data are presented for enzyme inhibition, antibacterial activity, and in vivo efficacy by oral and intravenous administration in two rodent infection models.
为了克服影响所有目前使用的抗生素种类的细菌耐药性问题,发现具有新颖作用机制的新型抗菌剂是必要的。细菌DNA促旋酶和拓扑异构酶IV是氟喹诺酮类抗生素的特征明确的临床验证靶标,它们通过抑制催化亚基发挥其抗菌活性。通过与它们的ATP位点相互作用来抑制这些靶标在临床上不太成功。提出了一种新型的低分子量,与ATP位点结合的回旋酶和拓扑异构酶IV合成抑制剂的发现和表征。苯并咪唑脲是两种酶的双重靶向抑制剂,并且对引起医院和社区获得性感染的各种相关病原体具有有效的抗菌活性。描述了通过使用结构指导的设计,建模和结构-活性关系来发现和优化这种新型抗菌剂。提供了在两种啮齿动物感染模型中通过口服和静脉内给药的酶抑制,抗菌活性和体内功效的数据。
