fragment-based drug design to bacterial DNA ligase. X-ray crystallography was used to guide structure-based optimization of a fragment-screening hit to give novel, nanomolar, AMP-competitive inhibitors. The lead compound 13 showed antibacterial activity across a range of pathogens. Data to demonstrate mode of action was provided using a strain of S. aureus, engineered to overexpress DNA ligase.
在此,我们描述了基于片段的药物设计在细菌 DNA 连接酶中的应用。X 射线晶体学用于指导片段筛选命中的基于结构的优化,以提供新型、纳摩尔、AMP 竞争性抑制剂。先导化合物13显示出对一系列病原体的抗菌活性。使用经过改造以过表达 DNA 连接酶的金黄色葡萄球菌菌株提供了证明作用方式的数据。
