  通过双重靶向IDO1和DNA提高癌症免疫疗法的效力

  摘要：

  在此，我们报告了首次探索双重靶向药物设计策略以提高小分子癌症免疫疗法的功效。合理设计了吲哚胺2，3-二加氧酶1（IDO1）抑制剂和分别将IDO1和DNA分别靶向氮芥的DNA烷基化杂种。作为此类分子的首例，它们在体外和体内均显示出显着增强的抗癌活性，且毒性低。这项概念验证研究为开发新型有效的免疫疗法治疗癌症迈出了关键的一步。

  使用新的Mn / Cu催化的溴-锌交换反应制备烷基溴化锌

  摘要：

  在由MnBr 2（或FeCl 3）和CuCl组成的催化混合金属体系存在下，官能化的伯烷基溴化物与Et 2 Zn在DMPU中的反应提供了官能化的烷基锌溴化物（收率> 80％）。在PdCl 2（dppf）或CuCN·2LiCl的存在下，这些有机锌物质会与一系列亲电试剂接触，从而以良好的收率提供各种多官能分子。

• Synthesis and serotonergic activity of 5-(oxadiazolyl)tryptamines: potent agonists for 5-HT1D receptors
  作者：Leslie J. Street、Raymond Baker、Jose L. Castro、Mark S. Chambers、Alexander R. Guiblin、Sarah C. Hobbs、Victor G. Matassa、Austin J. Reeve、Margaret S. Beer

  The selectivity of these compounds for 5-HT1D receptors over other serotonergic receptors is discussed. Sulfonamide 20t shows > or = 1000-fold selectivity for 5-HT1D over 5-HT2, 5-HT1C, and 5-HT3 receptors and 10-fold selectivity with respect to 5-HT1A receptors. The functional activity of this series of compounds is studied and demonstrates high 5-HT1D receptor potency and efficacy comparable to that

  描述了一系列新的5-（恶二唑基）色胺的合成和5-HT1D受体活性。研究了恶二唑3-取代基的修饰，连接链的长度（n）和胺取代基，并揭示了5-HT1D受体域中的大结合口袋。容纳恶二唑取代基如苄基而不会损失激动剂的效力或功效。在苯基或苄基间隔基团上引入极性官能团会导致亲和力和功能效能提高10倍。当杂环与吲哚偶联时，观察到最佳的5-HT1D活性，苄基磺酰胺20t和20u代表了一些已知的最有效的5-HT1D激动剂。杂环中的S取代O导致效能进一步提高。删除恶二唑N-2不会降低活性，建议在此位置仅需要一个H键受体。讨论了这些化合物对5-HT1D受体相对于其他血清素能受体的选择性。磺酰胺20t对5-HT1D的选择性比5-HT2、5-HT1C和5-HT3受体高> 1000倍，对5-HT1A受体的选择性高10倍。研究了该系列化合物的功能活性，并证明了与5-HT相当的5-HT1D受体效能和功效。

• The direct formation of functionalized alkyl(aryl)zinc halides by oxidative addition of highly reactive zinc with organic halides and their reactions with acid chlorides, .alpha.,.beta.-unsaturated ketones, and allylic, aryl, and vinyl halides
  作者：Lishan Zhu、Richard M. Wehmeyer、Reuben D. Rieke

  DOI：10.1021/jo00004a021

  日期：1991.2

  Highly reactive zinc, prepared by the lithium naphthalenide reduction of ZnCl2, readily undergoes oxidative addition to alkyl, aryl, and vinyl halides under mild conditions to generate the corresponding organozinc compounds in excellent yields. Significantly, the reaction will tolerate a spectrum of functional groups on the organic halides. Accordingly, this approach can now be used to prepare a wide variety of highly functionalized organozinc compounds. In the presence of Cu(I) salts, the organozinc compounds cross-couple with acid chlorides, conjugatively add to alpha,beta-unsaturated ketones, and regioselectively undergo S(N)2' substitution reactions with allylic halides. They also cross-couple with aryl or vinyl halides with Pd(0) catalysts.
• α-Diazo-β-ketonitriles: Uniquely Reactive Substrates for Arene and Alkene Cyclopropanation
  作者：Roger R. Nani、Sarah E. Reisman

  DOI：10.1021/ja401610p

  日期：2013.5.15

  An investigation of the intramolecular cyclopropanation reactions of alpha-diazo-beta-ketonitriles is reported. These studies reveal that alpha-diazo-beta-ketonitriles exhibit unique reactivity in their ability to undergo arene cyclopropanation reactions; other similar acceptor acceptor-substituted diazo substrates instead produce mixtures of C-H insertion and dimerization products. alpha-Diazo-beta-ketonitriles also undergo highly efficient intramolecular cyclopropanation of tri- and tetrasubstituted alkenes. In addition, the alpha-cyano-alpha-ketocyclopropane products are demonstrated to serve as substrates for S(N)2, S(N)2', and aldehyde cycloaddition reactions.
