  鉴定破坏 WDR5-MYC 蛋白质-蛋白质相互作用的 5-硫氰酸噻唑-2-胺

  摘要：

  MYC扩增经常在大约 50% 的人类癌症中观察到，使其成为非常理想的抗癌靶点。鉴于直接药理抑制 MYC 的挑战，削弱 MYC 及其关键辅因子 WDR5 的相互作用已被提议作为 MYC 驱动的癌症治疗的一种有前景的策略。在此，我们报告了破坏 WDR5-MYC 相互作用的 5-硫氰酸噻唑-2-胺的发现。命中片段最初是在内部文库基于荧光偏振 (FP) 的筛选中鉴定出来的，结构-活性关系探索产生了对 WDR5-MYC 相互作用具有有效抑制活性的先导化合物4m和4o ( K i = 2.4 μM 为4m ； K i = 1.0 μM 为4o )。这些化合物通过差示扫描荧光法 (DSF) 和免疫共沉淀 (Co-IP) 得到进一步验证。此外， 4m和4o对多种MYC驱动的癌细胞系表现出良好的细胞活性，IC 50值在微摩尔水平（IC 50 = 0.71–7.40 μM）。我们的研究结果提供了一种潜在的阻断

• Laccase-Catalysed Homocoupling of Primary Aromatic Amines towards the Biosynthesis of Dyes
  作者：Ana Catarina Sousa、Lígia O. Martins、M. Paula Robalo

  DOI：10.1002/adsc.201300501

  日期：2013.10.11

  AbstractColoured disubstituted benzoquinonimine trimeric structures are obtained as main reaction products of the oxidation of p‐electron donor primary aromatic amines using two different laccases, CotA‐laccase from Baccilus subtilus and TvL from Trametes versicolor. These orange‐red to purple products, presenting high molar extinction coefficients, presumably result from oxidative homocoupling reactions, through the formation of NC bonds at positions 2 and 5, of the laccase oxidised intermediate as showed in the proposed oxidative pathway. The product of 1,4‐phenylenediamine is shown to be the trimer known as Bandrowski’s base which has an established role in hair and fur dyeing. Our results also show that the occurrence and/or rates of oxidation of aromatic amines are strongly dependent on the presence of p‐electron releasing substituents in the aromatic ring and are independent on the properties of the enzyme used. Overall our data contribute for (i) understanding key features of laccase reactivity with p‐substituted aromatic amines and (ii) establishing enzymatic processes that lead to the synthesis of coloured bio‐products under mild conditions with potential impact in the cosmetic and dye industries.magnified image
• Convenient and Reliable Routes Towards 2-Aminothiazoles: Palladium-Catalyzed<i>versus</i>Copper-Catalyzed Aminations of Halothiazoles
  作者：Stéphanie Toulot、Timo Heinrich、Frédéric R. Leroux

  DOI：10.1002/adsc.201300591

  日期：2013.11.11

  AbstractTwo efficient methods for the amination of 2‐halothiazoles are presented here. A first protocol requires a Pd/L system. Several 2‐aminothiazoles were synthesized under optimized conditions and isolated in good yields. The first palladium‐catalyzed CN coupling reactions between 2‐halothiazoles and primary alkylamines are presented. In a second part, ligand‐free copper‐catalyzed aminations of 2‐halothiazoles by alkylamines and aniline in a green solvent have been developed. The protocol is very effective for primary and secondary amines and perfectly tolerates the presence of another halide moiety on the 2‐halothiazole. The reaction occurs under the assistance of microwave irradiation, which drastically decreases the reaction time. The reaction leads to the formation of 2‐aminothiazoles, key molecules in pharmaceutical research.magnified image
