  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.

• Silver-catalyzed stereoselective formation of glycosides using glycosyl ynenoates as donors
  作者：Xu Dong、Li Chen、Zhitong Zheng、Xu Ma、Zaigang Luo、Liming Zhang

  DOI：10.1039/c8cc02494d

  日期：——

  A silver-catalyzed glycosylation reaction employing readily accessible and stable glycosyl ynenoates is developed. This reaction is mostly high yielding and exhibits varying levels of stereoinversion at the anomeric position. Compared to established and versatile Yu's gold catalysis, this chemistry features the use of substantially cheaper AgNTf2.

  已开发出一种银催化的糖基化反应，该反应采用了易于获得且稳定的糖基炔诺酸酯。该反应大部分是高收率的，并且在异头位置显示出不同水平的立体转化。与已建立且用途广泛的Yu的金催化方法相比，该化学方法的特点是使用了便宜得多的AgNTf 2。
• SilverCatalyzed Cascade Carboxylation and Cyclization of Trimethyl(2-methylenebut-3-yn-1-yl)silane Derivatives

  C-C bond forming carboxylation, and cyclization: of trimethyl(2-rnethylenbut-3,7yl)silaile derivatives and carbon dioxide was developed. Silver catalysts and CsF promoted the reaction to afford the:corresponding 2-furanone and 2-pyrone derivatives in good-to-high yields. The structure of the 2:furanone was confirmed by single-crystal X-ray crystallography, which revealed that the geometry of the exo-olefin was that of a Z-isomer. When an aromatic ring substituted alkyne was used, 2-furanone derivatives were selectively obtained via 5-exo-dig-cyclization, whereas the reaction of alkyl-substituted alkynes produced 2-pyrone derivatives with high selectivity.
