  一种以季铵盐催化炔烃制备烯烃和烷烃的方法

  摘要：

  本发明公开了一种以季铵盐催化炔烃制备烯烃和烷烃的方法，该方法包括以下步骤：1）以炔烃为起始原料，在手套箱中，将炔烃、季铵盐催化剂加入反应管中，再添加一定量的有机溶剂后通入0.5‑3MPa的氢气在恒温下进行搅拌反应得到反应液；2）将所述反应液除去挥发性溶剂后通过柱层析纯化即得烯烃或烷烃。本发明以廉价易得的氢气为氢源，采用有机小分子季铵盐作为催化剂，无需过渡金属、无需氧化剂即可实现炔烃类化合物的氢化，不仅降低了实验所需费用，大大降低生产成本，而且原子利用率高、不会产生任何副产物。本发明采用的催化剂反应条件温和、催化体系简单、反应选择性高，环境友好、催化稳定，易得并且容易回收，绿色环保，值得推广应用。

  Discovery of a novel series of N -hydroxypyridone derivatives protecting astrocytes against hydrogen peroxide-induced toxicity via improved mitochondrial functionality

  摘要：

  Astrocytes play a key role in brain homeostasis, protecting neurons against neurotoxic stimuli such as oxidative stress. Therefore, the neuroprotective therapeutics that enhance astrocytic functionality has been regarded as a promising strategy to reduce brain damage. We previously reported that ciclopirox, a well-known antifungal N-hydroxypyridone compound, protects astrocytes from oxidative stress by enhancing mitochondrial function. Using the N-hydroxypyridone scaffold, we have synthesized a series of cytoprotective derivatives. Mitochondrial activity assay showed that N-hydroxypyridone derivatives with biphenyl group have comparable to better protective effects than ciclopirox in astrocytes exposed to H2O2. N-hydroxypyridone derivatives, especially 11g, inhibited membrane-induced deterioration of mitochondrial membrane potential and oxygen consumption rate, and significantly improved cell viability of astrocytes. The results indicate that the N-hydroxypyridone motif can provide a novel cytoprotective scaffold for astrocytes via enhancing mitochondrial functionality. (C) 2017 Elsevier Ltd.
