  Inhibitors of the acetyltransferase domain of N-acetylglucosamine-1-phosphate-uridylyltransferase/glucosamine-1-phosphate-acetyltransferase (GlmU). Part 2: Optimization of physical properties leading to antibacterial aryl sulfonamides

  摘要：

  A previously described aryl sulfonamide series, originally found through HTS, targets GlmU, a bifunctional essential enzyme involved in bacterial cell wall synthesis. Using structure-guided design, the potency of enzyme inhibition was increased in multiple isozymes from different bacterial species. Unsuitable physical properties (low Log D and high molecular weight) of those compounds prevented them from entering the cytoplasm of bacteria and inhibiting cell growth. Further modifications described herein led to compounds that possessed antibacterial activity, which was shown to occur through inhibition of GlmU. The left-hand side amide and the right-hand side sulfonamides were modified such that enzyme inhibitory activity was maintained (IC50 <0.1 mu M against GlmU isozymes from Gram-negative organisms), and the lipophilicity was increased giving compounds with Log D -1 to 3. Antibacterial activity in an efflux-pump deficient mutant of Haemophilus influenzae resulted for compounds such as 13. (C) 2012 Elsevier Ltd. All rights reserved.
