  Synthesis, biological evaluation and molecular docking studies of benzyloxyacetohydroxamic acids as LpxC inhibitors

  摘要：

  The inhibition of the UDP-3-O-[(R)-3-hydroxymyristoyl]-N-acetylglucosamine deacetylase (LpxC) represents a promising strategy to combat infections caused by multidrug-resistant Gram-negative bacteria. In order to elucidate the functional groups being important for the inhibition of LpxC, the structure of our previously reported hydroxamic acid 4 should be systematically varied. Therefore, a series of benzyloxyacetohydroxamic acids was prepared, of which the diphenylacetylene derivatives 28 (K-i = 95 nM) and 21 (K-i = 66 nM) were the most potent inhibitors of Escherichia coli LpxC. These compounds could be synthesized in a stereoselective manner employing a Sharpless asymmetric dihydroxylation and a Sonogashira coupling in the key steps. The obtained structure-activity relationships could be rationalized by molecular docking studies. (C) 2013 Elsevier Ltd. All rights reserved.

  Asymmetric reduction of prochiral α- and β-hydroxy ketones with a reagent, generated from tin(II) chloride, a chiral diamine, and diisobutylaluminum hydride, afforded the corresponding dihydroxy compounds in good chemical and optical yields. Optical yields depended on the nature of the protective groups of hydroxyl function.

  altered the transition state. Substrate mapping analysis strongly suggested that the CH/π interaction partly enhanced the (R)-enantiomer reactivity, the estimated energy of the CH/π interaction being −0.4 kcal mol−1. The substrate scope of the I287F/I290A double mutant was broad. This biocatalyst was useful for the dynamic kinetic resolution of a variety of bulky secondary alcohols for which the wild-type

  对于大多数脂肪酶而言，在羟基的两侧均具有大的取代基的仲醇固有地是较差的底物。鉴于这种弱点，我们重新设计了洋葱伯克霍尔德氏菌脂肪酶，以创建具有改善的酶促特性的变体。对于野生型酶显示低转化率和低E值的不良底物，I287F / I290A双突变体显示出高转化率和E值（> 200）（5）。该变体的催化活性和对映体选择性的增强是由于两个突变的协同作用引起的：Phe287既有助于增强（R）-对映异构体反应性，又可以抑制（S）-对映体的反应性，而Ala290则为促进（R）-对映体的酰化创造了空间。动力学常数表明突变有效地改变了过渡状态。底物作图分析强烈表明，CH /π相互作用部分增强了（R）-对映异构体的反应性，CH /π相互作用的估计能量为-0.4 kcal mol -1。I287F / I290A双突变体的底物范围很广。这种生物催化剂可用于动态动力学拆分各种大体积的仲醇，而野生型酶几乎没有或没有活性。
