Inhibitors of the bacterial enzyme dapE-encoded -succinyl-L,L-diaminopimelic acid desuccinylase (DapE; EC 3.5.1.18) hold promise as antibiotics with a new mechanism of action. Herein we describe the discovery of a new series of indoline sulfonamide DapE inhibitors from a high-throughput screen and the synthesis of a series of analogs. Inhibitory potency was measured by a ninhydrin-based DapE assay recently developed by our group. Molecular docking experiments suggest active site binding with the sulfonamide acting as a zinc-binding group (ZBG).
细菌酶dapE编码的琥珀酰-L,L-二氨基庚二酸去琥珀酰化酶(DapE;EC 3.5.1.18)抑制剂有望成为具有新作用机制的抗生素。在此,我们描述了通过高通量筛选发现的一系列新的吲哚啉磺酰胺DapE抑制剂以及一系列类似物的合成。抑制效力通过我们小组最近开发的基于茚三酮的DapE测定法进行测量。分子对接实验表明,活性位点结合时磺酰胺作为锌结合基团(ZBG)起作用。
