was used to give novel oxazolidinone-based LpxC inhibitors. In particular, the most potent compound, 23j, showed a low efflux ratio, nanomolar potencies against E. coli LpxC enzyme, and excellent antibacterial activity against E. coli and K. pneumoniae. Computational docking was used to predict the interaction between 23j and E. coli LpxC, suggesting that the interactions with C207 and C63 contribute
在本文中,我们报告了一种支架跳跃方法,以鉴定具有锌结合头基的新支架。结构信息用于提供基于恶唑烷酮的新型LpxC抑制剂。特别地,最有效的化合物23j显示出低的流出比,对大肠杆菌LpxC酶的纳摩尔效价和对大肠杆菌和肺炎克雷伯菌的极好的抗菌活性。计算对接用于预测23j与大肠杆菌LpxC之间的相互作用,这表明与C207和C63的相互作用有助于产生强活性。这些结果为下一代LpxC抑制剂的设计提供了新的见识。
