  Towards Gram-negative antivirulence drugs: New inhibitors of HldE kinase

  摘要：

  Gram-negative bacteria lacking heptoses in their lipopolysaccharide (LPS) display attenuated virulence and increased sensitivity to human serum and to some antibiotics. Thus inhibition of bacterial heptose synthesis represents an attractive target for the development of new antibacterial agents. HldE is a bifunctional enzyme involved in the synthesis of bacterial heptoses. Development of a biochemical assay suitable for high-throughput screening allowed the discovery of inhibitors 1 and 2 of HldE kinase. Study of the structure-activity relationship of this series of inhibitors led to highly potent compounds. (c) 2008 Elsevier Ltd. All rights reserved.

  N-酰基-β-羟基氨基酸衍生物合成取代恶唑

  摘要：

  制备了几种 N-酰基-β-羟基氨基酸，并在 4-（二甲氨基）吡啶存在下用二碳酸二叔丁酯处理，然后用 N,N,N',N'-四甲基胍处理，得到相应的N-酰基脱氢氨基酸的产率很高。然后用 I2/K2CO3 和 1,8-二氮杂双环 [5.4.0] undec-7-ene 处理这些。N-酰基脱氢氨基丁酸的甲酯以良好至高产率得到相应的取代恶唑。N-酰基脱氢苯丙氨酸与β-碘脱氢苯丙氨酸一起以低至中等产率得到5-苯基恶唑衍生物。在相同条件下，N-酰基脱氢丙氨酸不能得到相应的恶唑。然而，当反应在没有 DBU 的情况下进行时，可以分离出 β,β-二碘脱氢丙氨酸衍生物。尽管我们并不完全清楚 N-酰基脱氢氨基酸不同反应性的原因，但循环伏安法研究表明，反应性较低的衍生物具有更高的还原电位。这表明脱氢氨基丁酸衍生物中的双键更容易受到碘的亲电攻击。 (© Wiley-VCH Verlag GmbH & Co.

  A small library of compounds with an oxa(thia)zole scaffold and structural diversity in both positions 2 and 5 has been synthesized. Double acylation of a protected glycine affords intermediate alpha-amido-beta-ketoesters, which in turn can be dehydrated to afford 1,3-oxazoles or reacted with Lawesson's reagent to furnish 1,3-thiazoles. This procedure was designed with its adaptation to fluorous techniques in mind. Thus, when a protected glycine With a fluorous tag in the ester moiety IS used as a starting material, the synthesis can be easily completed Without column chromatography purification of intermediate compounds with good to excellent yields, thus affording a Suitable entry to the preparation of small libraries of these bioactive compounds. The prepared oxa(thia)zoles were assayed for their antibacterial activity, and several of them were active against Staphylococcus aureus.
