Inhibitors of the bacterial enzyme dapE-encoded N-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
细菌酶 dapE 编码的N-琥珀酰-L,L-二氨基庚二酸脱琥珀酰酶 (DapE; EC 3.5.1.18) 的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二氢吲哚磺酰胺 DapE 抑制剂以及一系列类似物的合成。抑制效力是通过我们小组最近开发的基于茚三酮的 DapE 测定法来测量的。分子对接实验表明,活性位点与磺酰胺结合,充当锌结合基团 (ZBG)。
