  天然烷基甘油的对映体合成及其抗菌和抗生物膜活性

  摘要：

  摘要 烷基甘油（AKGs）是通过烷基链长和不饱和度而变化的生物活性的天然化合物，它们的绝对构型为2小号。三个 AKGs ( 5l – 5n ) 以对映体纯的形式合成，并首次与其他 12 个已知和天然存在的 AKGs ( 5a – 5k , 5o )一起表征。它们的结构是使用1 H 和13 C APT NMR 与 2D-NMR、ESI-MS 或 HRESI-MS 和旋光数据建立的，并测试了它们的抗菌和抗生物膜活性。AKG 5a – 5m和5o对五种临床分离株和铜绿假单胞菌ATCC 15442显示出活性，MIC 值在 15–125 µg/mL 范围内。此外，在 MIC 的一半时，大多数 AKG 减少了 23%–99% 范围内的金黄色葡萄球菌生物膜形成和14%–64% 范围内的铜绿假单胞菌ATCC 15442 生物膜形成。在这项工作中评估的 AKG 的抗生物膜活性以前没有被研究过。

  Inhibition of Oleamide Hydrolase Catalyzed Hydrolysis of the Endogenous Sleep-Inducing Lipid cis-9-Octadecenamide

  摘要：

  Oleamide (1, cis-9-octadecenamide) is a naturally occurring brain constituent that. has been shown to accumulate and disappear under conditions of sleep deprivation and sleep recovery, respectively. Synthetic 1 has been found to induce sleep in a structurally specific manner at nanomolar quantities. Hydrolysis of 1 by an enzyme (oleamide hydrolase) present in the cell membrane rapidly degrades oleamide to oleic acid (cis-9-octadecenoic acid). Such observations suggest 1 may constitute a prototypical member of a class of fatty acid primary amide biological signaling molecules in which the diversity and selectivity of function are derived from the length of the alkane chain as well as the position, stereochemistry, and degree of unsaturation. A series of inhibitors of oleamide hydrolase were designed and prepared which were expected to derive their properties through interactions with the putative active site cysteine residue within oleamide hydrolase. This approach yielded a series of rapid, selective, and highly potent inhibitors (K-i = 13 mu M to 1 nM) which in addition to their potential therapeutic value may serve as useful tools to define the biological role of oleamide.

  aromatic and aliphatic hydroxamic acids were converted to the corresponding primary amines via base-mediated rearrangement. This rearrangement could proceed with less than 1 equiv. of K2CO3 in polar solvents under thermal conditions with no external reagents. This rearrangement has several features including no external activating agents needed for promoting the rearrangement, less than one equivalent of

  Alkylglycerols (AKGs) are bioactive natural compounds that vary by alkyl chain length and degree of unsaturation, and their absolute configuration is 2S. Three AKGs (5l–5n) were synthesised in enantiomerically pure form, and were characterised for the first time together with 12 other known and naturally occurring AKGs (5a–5k, 5o). Their structures were established using 1H and 13C APT NMR with 2D-NMR
