  铜铁离子诱导白藜芦醇氧化偶联的实验与理论联合研究

  摘要：

  摘要 目前，人们对多酚类化合物的生物活性越来越感兴趣，多酚类化合物已被认为对人类健康产生积极影响。在本文中，我们报告了第一次电喷雾电离质谱 (ESI-MS) 研究，从含有白藜芦醇和 CuSO 4 或 FeCl 的乙腈/水溶液开始，气相生产外消旋形式的异构 δ-葡萄素和 ɛ-葡萄素二聚体3、分别。有趣的是，在对白藜芦醇-铜混合物进行的 ESI-MS 实验中观察到外消旋 δ-葡萄素脱氢二聚体的形成，而类似的白藜芦醇-铁反应提供了外消旋 ɛ-葡萄素脱氢二聚体。使用气相技术和从头计算，在 BHandHLYP/LACV3P + +** 理论水平，使我们能够阐明这些反应机制的一些重要方面。特别是，在铜离子存在下，参与氧化偶联的白藜芦醇自由基具有不同的稳定性，有利于 δ-葡萄素的形成，正如铜能够将白藜芦醇从抗氧化剂到促氧化剂。最后，研究了白藜芦醇合成类似物的结构-反应关系，显示了对位 OH 基团的关键作

  Galloyl esters of trans-stilbenes are inhibitors of FASN with anticancer activity on non-small cell lung cancer cells

  摘要：

  Fatty acid synthase (FASN) is a lipogenic enzyme that is selectively upregulated in malignant cells. There is growing consensus on the oncogenicity of FASN-driven lipogenesis and the potential of FASN as a druggable target in cancer. Here, we report the synthesis and FASN inhibitory activities of two novel galloyl esters of trans-stilbene EC1 and EC5. Inhibition of FASN was accompanied by a loss in AKT activation and profound apoptosis in several non-small cell lung cancer (NSCLC) cells at the growth inhibitory concentrations of EC1 and EC5. Both FASN and phospho-AKT levels were concurrently downregulated. However, addition of a lipid concentrate to the treated cells reinstated cell viability and reversed the loss of FASN and AKT protein levels, thus recapitulating the causal relationship between FASN inhibition and the loss in cell viability.

  C═C bond breaking to access the C═N bond remains an underdeveloped area. A new protocol for C═C bond cleavage of alkenes under nonoxidative conditions to produce imines via an iron-catalyzed nitrene transfer reaction of 4-hydroxystilbenes with aryl azides is reported. The success of various sequential one-pot reactions reveals that the good compatibility of this method makes it very attractive for
