inhibitor of FabI from S. aureus (IC(50) = 2.4 microM) and Haemophilus influenzae (IC(50) = 4.2 microM). Compound 9 has good in vitro antibacterial activity against several organisms, including S. aureus (MIC = 0.5 microg/mL), and is effective in vivo in a S. aureus groin abscess infection model in rats. Through FabI overexpressor and macromolecular synthesis studies, the mode of action of 9 has been confirmed
细菌烯酰-ACP还原酶(FabI)催化细菌脂肪酸生物合成的每个循环中的最后一步,是开发新型抗菌剂的有吸引力的目标。我们鉴定有效的选择性FabI抑制剂的努力始于对GlaxoSmithKline专有化合物的筛选,该鉴定了几种金黄色葡萄球菌FabI的小分子抑制剂。通过结合迭代化学化学和基于X射线晶体结构的设计,将这些引线之一开发为新型氨基吡啶衍生物9,一种来自金黄色葡萄球菌(IC(50)= 2.4 microM)和嗜血杆菌的低微摩尔FabI抑制剂。流感(IC(50)= 4.2 microM)。化合物9对包括金黄色葡萄球菌(MIC = 0.5 microg / mL)在内的几种生物具有良好的体外抗菌活性,并且在S. 大鼠金黄色腹股沟脓肿感染模型。通过FabI过表达子和大分子合成研究,已证实9的作用方式是通过抑制FabI来抑制脂肪酸生物合成。综上所述,这些结果支持FabI作为有效的抗菌靶标,并证明了
