  Analogs of .gamma.-hydroxybutyric acid. Synthesis and binding studies

  摘要：

  Substituted 4-hydroxybutyric (GHB) or trans-4-hydroxycrotonic acids (T-HCA) and structurally related compounds were synthesized and submitted to [3H]GHB binding. Structure-activity relationships studies highlighted for [3H]GHB binding (a) the necessity of a nonlactonic, relatively extended conformation of the gamma-hydroxybutyric chain, (b) the existence of some bulk tolerance in the vicinity of the hydroxyl group, and (c) the high sensitivity toward isosteric replacements of the carboxyl or the hydroxyl groups. T-HCA has been recently identified as a naturally occurring substance in the central nervous system (CNS) and shows a better affinity than GHB. Our findings are in favor of the presence in the CNS of specific GHB binding sites, which are different from the GABA and the picrotoxin binding sites, and for which T-HCA may be an endogenous ligand.

  4-Oxobutenoic acids are useful as biologically active species and as versatile intermediates for further derivatisation. Currently, routes to their synthesis can be problematic and lack generality. Reaction conditions for the synthesis of 4-oxo-2-butenoic acid by microwave-assisted aldol-condensation between methyl ketone derivatives and glyoxylic acid have been developed. They provide the desired

  4-氧代丁烯酸可用作生物活性物质和用于进一步衍生化的通用中间体。目前，它们的合成路线可能存在问题并且缺乏通用性。开发了甲基酮衍生物与乙醛酸微波辅助羟醛缩合合成4-氧代-2-丁烯酸的反应条件。他们通过对可获得的起始材料应用简单的程序，以中等至优异的产率为各种底物提供所需的产品。研究表明，根据甲基酮取代基的性质，需要不同的条件，芳基衍生物使用对甲苯磺酸反应最好，而脂肪族底物与吡咯烷和乙酸反应最好。这种取代基效应通过前沿轨道计算得到合理化。总的来说，这项工作提供了在多种底物上合成 4-氧代丁烯酸的方法。

  Protein kinase B (PknB) is an essential serine/threonine protein kinase required for Mycobacterium tuberculosis (M. tb) cell division and cell-wall biosynthesis. A high throughput screen using PknB identified a (E)-4-oxo-crotonic acid inhibitor, named YH-8, which was used as a scaffold for SAR investigations. A significant improvement in enzyme affinity was achieved. The results indicated that the

  蛋白激酶B（PknB）是结核分枝杆菌（M. tb）细胞分裂和细胞壁生物合成所必需的丝氨酸/苏氨酸蛋白激酶。使用PknB进行的高通量筛选鉴定出一种名为YH-8的（E）-4-氧代巴豆酸抑制剂，该抑制剂被用作SAR研究的支架。实现了酶亲和力的显着改善。结果表明，α，β-不饱和酮骨架和“反式”构型对于对抗PknB的活性至关重要。而且具有芳基的化合物，特别是在苯环上具有吸电子取代基的化合物，其效能是YH-8的四倍。

  A series of novel (E)-4-oxo-2-crotonamide derivatives were designed and synthesized to find potent antituberculosis agents. All the target compounds were evaluated for their in vitro activity against Mycobacterium tuberculosis H37Rv(MTB). Results reveal that 4-phenyl moiety at part A and short methyl group at part C were found to be favorable. Most of the derivatives displayed promising activity against
