• Ethynyl Benziodoxolones for the Direct Alkynylation of Heterocycles: Structural Requirement, Improved Procedure for Pyrroles, and Insights into the Mechanism
  作者：Jonathan P. Brand、Clara Chevalley、Rosario Scopelliti、Jérôme Waser

  DOI：10.1002/chem.201200200

  日期：2012.4.27

  accelerating effect of a methyl substituent in both the 3‐ and 6‐position of triisopropylsilylethynyl‐1,2‐benziodoxol‐3(1H)‐one (TIPS‐EBX) on the reaction rate was observed. Competitive experiments between substrates of different nucleophilicity, deuterium labeling experiments, as well as the regioselectivity observed are all in agreement with electrophilic aromatic substitution. Gold(III) 2‐pyridinecarboxylate

  本报告描述了使用炔基高价碘试剂对金催化的吲哚，吡咯和噻吩直接炔基化的全面研究，尤其是炔基苯并恶唑烷酮对乙炔有效转移至杂环的结构要求的研究。还报道了使用吡啶作为添加剂的吡咯烷基炔化的改进方法。在吲哚和/或噻吩的直接炔基化反应中，合成并评估了十九个炔基苯并恶唑醇。最佳的甲硅烷基取代基是庞大的甲硅烷基。尽管如此，还是第一次实现了芳族乙炔向噻吩的转移。甲基取代基在三异丙基甲硅烷基乙炔基1,2-苯并恶多酚3（1 H）观察到反应速率为1（TIPS-EBX）。不同亲核性底物之间的竞争性实验，氘标记实验以及观察到的区域选择性均与亲电子芳族取代一致。金（III）2-吡啶羧酸二氯盐也是该反应的有效催化剂。研究表明，在此过程中，金（III）最终可能还原为金（I）。这些研究的结果是，炔基化反应最有可能发生π活化或氧化机理。
• Selectivity Optimization of Substituted 1,2,3-Triazoles as α7 Nicotinic Acetylcholine Receptor Agonists
  作者：Kuntarat Arunrungvichian、Valery V. Fokin、Opa Vajragupta、Palmer Taylor

  DOI：10.1021/acschemneuro.5b00058

  日期：2015.8.19

  Three series of substituted anti-1,2,3-triazoles (IND, PPRD, and QND), synthesized by cycloaddition from azide and alkyne building blocks, were designed to enhance selectivity and potency profiles of a lead alpha 7 nicotinic acetylcholine receptor (alpha 7-nAChR) agonist, TTIn-1. Designed compounds were synthesized and screened for affinity by a radioligand binding assay. Their functional characterization as agonists and antagonists was performed by fluorescence resonance energy transfer assay using cell lines expressing transfected cDNAs, alpha 7-nAChRs, alpha 4 beta 2-nAChRs, and 5HT(3A), receptors, and a fluorescence cell reporter. In the END series, a tropane ring of TTIn-1, substituted at Ni, was replaced by mono- and bicyclic amines to vary length and conformational flexibility of a carbon linker between nitrogen atom and Ni of the triazole. Compounds with a two-carbon atom linker optimized binding with K-d's at the submicromolar level. Further modification at the hydrophobic indole of TTIn-1 was made in PPRD and QND series by fixing the amine center with the highest affinity building blocks in the IND series. Compounds from IND and PPRD series are selective as agonists for the alpha 7-nAChRs over alpha 4 beta 2-nAChRs and 5HT(3A) receptors. Lead compounds in the three series have EC50's between 28 and 260 nM. Based on the EC50, affinity, and selectivity determined from the binding and cellular responses, two of the leads have been advanced to behavioral studies described in the companion article (DOI: 10.1021/acschemneuro.5b00059).
• Click chemistry to probe Hsp90: Synthesis and evaluation of a series of triazole-containing novobiocin analogues
  作者：Laura B. Peterson、Brian S.J. Blagg

  DOI：10.1016/j.bmcl.2010.04.140

  日期：2010.7

  A series of triazole-containing novobiocin analogues has been designed, synthesized and their inhibitory activity determined. These compounds contain a triazole ring in lieu of the amide moiety present in the natural product. The anti-proliferative effects of these compounds were evaluated against two breast cancer cell lines ( SKBr-3 and MCF-7), and manifested activities similar to their amide-containing counterparts. In addition, Hsp90-dependent client protein degradation was observed via Western blot analyses, supporting a common mode of Hsp90 inhibition for both structural classes. (C) 2010 Elsevier Ltd.
