Abstract: | N-Acyl sulfamoyladenosines (acyl-AMS) have been used extensively to inhibit adenylate-forming enzymes that are involved in a wide range of biological processes. These acyl-AMS inhibitors are nonhydrolyzable mimics of the cognate acyl adenylate intermediates that are bound tightly by adenylate-forming enzymes. However, the anionic acyl sulfamate moiety presents a pharmacological liability that may be detrimental to cell permeability and pharmacokinetic profiles. We have previously developed the acyl sulfamate OSB-AMS (1) as a potent inhibitor of the adenylate-forming enzyme MenE, an o-succinylbenzoate-CoA (OSB-CoA) synthetase that is required for bacterial menaquinone biosynthesis. Herein, we report the use of computational docking to develop novel, non-acyl sulfamate inhibitors of MenE. A m-phenyl ether-linked analogue (5) was found to be the most potent inhibitor (IC 50 = 8 μM; K d = 244 nM), and its X-ray co-crystal structure was determined to characterize its binding mode in comparison to the computational prediction. This work provides a framework for the development of potent non-acyl sulfamate inhibitors of other adenylate-forming enzymes in the future. Copyright © 2019 American Chemical Society. |
