  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.

• Chemoselective Acylation of Amines in Aqueous Media

  Amines are efficiently acylated by both cyclic and acyclic anhydrides by dissolving them in an aqueous medium with the help of a surfactant, sodium dodecyl sulfate (SDS). Cyclic and acyclic anhydrides react with equal ease with an amine, and amines with various stereo-electronic factors react at the same rates with an anhydride. Chemoselective acylation of amines in the presence of phenols and thiols

  通过在表面活性剂十二烷基硫酸钠 (SDS) 的帮助下将胺溶解在水性介质中，胺被环状酸酐和无环酸酐有效地酰化。环状和无环酸酐与胺反应同样容易，具有各种立体电子因子的胺与酸酐以相同的速率反应。已经实现了在酚类和硫醇存在下胺的化学选择性酰化以及在酚存在下硫醇的化学选择性酰化。反应过程中不使用酸性或碱性试剂。分离酰化产物不需要色谱分离。在中性水性介质中反应，产物容易分离，副产物无害，使本方法成为一种绿色化学过程。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)

  silylation using hydrosilane was developed. This cross-dehydrogenative silylation enables both electron-rich and electron-poor aromatics to afford the desired arylsilanes in unique selectivity. A “para-selectivity” was observed by examination of over 54 examples. This exceptional orientation is quite different from that in Friedel–Crafts C–H silylation or transition-metal-catalyzed dehydrogenative silylation

  Selective oxidative homo- and cross-coupling of electron-rich phenols and anilides was developed using nitrosonium tetrafluoroborate as a catalyst. Oxidative coupling of phenols revealed unusual selectivities, which translated into the unprecedented synthesis of inverse Pummerer-type ketones. Mechanistic studies suggest that oxidative coupling of phenols and anilides shares a common pathway via homolytical

  使用四氟硼酸氮鎓作为催化剂，开发了富电子的苯酚和苯甲酸酯的选择性氧化均相和交叉偶联。酚类的氧化偶联显示出不同寻常的选择性，这转化为反Pummerer型酮的空前合成。机理研究表明，酚和苯甲酸酯的氧化偶合通过均质杂原子-氢键裂解具有共同的途径。硝盐催化被应用到由杂原子为中心的自由基的产生引发的交叉脱氢偶联。

  The present invention relates to a method for synthesising amides that is of general applicability. The method may be performed in vitro or in vivo. Cell lines for use in the in vivo methods also form aspects of the invention. The method for synthesising a non-natural amide comprises: a. reaction of a carboxylic acid with a naturally occurring CoA ligase or a variant thereof; and b. reaction of the product of step a with an amine in the presence of a naturally occurring acyltransferase or a variant thereof; with the proviso that where the CoA ligase and acyltransferase are both naturally occurring, they are not derived from the same source species and do not act sequentially in a metabolic pathway; and with the proviso that the non-natural product is not N-(E)-p-coumaroyl-3-hydroxyanthranilic acid or N-(E)-p-caffeoyl-3-hydroxyanthranilic acid. Further, a method for producing an active pharmaceutical ingredient by the aforementioned method and host cells for carrying out said methods are envisaged.
