  Application of Aryl Siloxane Cross-Coupling to the Synthesis of Allocolchicinoids

  摘要：

  In this communication, we report a new approach to the allocolchicine carbocyclic skeleton based upon an aryl siloxane coupling reaction and a phenanthrol ring expansion. These key steps allow for the selective functionalization of every carbon within the carbocyclic framework. The siloxane coupling-phenanthrol sequence was applied to the synthesis of two allocolchicinoids, including the first fully synthetic approach to N-acetyl colchinol-O-methyl ether (NCME).

• Synthesis of Flavokawain Analogues and their Anti-neoplastic Effects on Drug-resistant Cancer Cells Through Hsp90 Inhibition
  作者：Young Ho Seo、Sun You Park

  DOI：10.5012/bkcs.2014.35.4.1154

  日期：2014.4.20

  Hsp90 is an ubiquitous molecular chaperone protein, which plays an important role in regulating maturation and stabilization of many oncogenic proteins. Due to its potential to simultaneously disable multiple signaling pathways, Hsp90 represents great promise as a therapeutic target of cancer. In this study, we synthesized flavokawain analogues and evaluated their biological activities against drug-resistant cancer cells. The study indicated that compound 1i impaired the growth of gefitinib-resistant non-small cell lung cancer (H1975), down-regulated the expression of Hsp90 client proteins including EGFR, Her2, Met, Akt and Cdk4, and upregulated the expression of Hsp70. The result strongly suggested that compound 1i inhibited the proliferation of cancer cells through Hsp90 inhibition. Overall, compound 1i could serve as a potential lead compound to overcome the drug resistance in cancer chemotherapy.

  Hsp90是一种普遍存在的分子伴侣蛋白，在调节多种致癌蛋白的成熟和稳定中起着重要作用。由于其同时禁用多个信号通路的潜力，Hsp90作为癌症的治疗靶点具有巨大前景。在本研究中，我们合成了黄卡瓦醇类似物，并评估了它们对耐药癌细胞的生物活性。研究表明，化合物1i损害了吉非替尼耐药的非小细胞肺癌（H1975）的生长，下调了包括EGFR、Her2、Met、Akt和Cdk4在内的Hsp90客户蛋白的表达，并上调了Hsp70的表达。结果强烈表明，化合物1i通过抑制Hsp90抑制了癌细胞的增殖。总的来说，化合物1i有可能作为一种潜在的先导化合物，克服癌症化疗中的药物耐药性。

  日期：2012.2

  A series of 4-formyl esters 8a–d was prepared by Michael addition of an enamine with ethyl acrylate. A subsequent condensation with 2-bromobenzylamines 3 gave rise to cyclic enamides 9aa–dd. In a Heck cyclization reaction tricyclic isoindoles 10aa–dd were formed in good yields.

  通过将烯胺与丙烯酸乙酯进行迈克尔加成反应，制备了一系列的4-甲酸酯8a – d。随后与2-溴苄胺3缩合，生成环状酰胺9aa – dd。在Heck环化反应中，三环异吲哚10aa – dd以良好的收率形成。
• Nanocrystalline Titania-Supported Palladium(0) Nanoparticles for Suzuki-Miyaura Cross-Coupling of Aryl and Heteroaryl Halides

  DOI：10.1002/adsc.201100012

  日期：2011.10

  The Suzuki cross-coupling reaction of various aryl and heteroaryl halides with arylboronic and heteroarylboronic acids was studied using a titania-supported palladium(0) catalyst at room temperature under air. The conversion and selectivity results obtained for many substrates were excellent and similar to those provided by more active or even homogeneous catalysts. The methodology is similarly effective

  使用二氧化钛负载的钯（0）催化剂在室温下于空气中研究了各种芳基和杂芳基卤化物与芳基硼酸和杂芳基硼酸的Suzuki交叉偶联反应。对于许多底物，获得的转化率和选择性结果极好，与活性更高甚至均相的催化剂所提供的结果相似。使用2-溴-3,4,5-三甲氧基苯甲醛作为偶合伙伴，该方法同样有效，并获得了高收率的产品。此外，已表明其可用于合成三联苯和四联苯。通过简单的过滤从反应中定量回收催化剂，并重复使用多个循环，而活性没有明显损失。
