  Conversion of systemically-distributed triazole-based stearoyl-CoA desaturase (SCD) uHTS hits into liver-targeted SCD inhibitors

  摘要：

  It has been demonstrated that once-a-day dosing of systemically-distributed SCD inhibitors leads to adverse events in eye and skin. Herein, we describe our efforts to convert a novel class of systemically-distributed potent triazole-based uHTS hits into liver-targeted SCD inhibitors as a means to circumvent chronic toxicity.

  proposed binding mode of the preferred substrate, Aβ3E−42. An in vitro structure–activity relationship study identified several excellent QC inhibitors demonstrating 5- to 40-fold increases in potency compared to a known QC inhibitor. When tested in mouse models of AD, compound 212 significantly reduced the brain concentrations of pyroform Aβ and total Aβ and restored cognitive functions. This potent Aβ-lowering

  谷氨酰胺基环化酶（QC）通过产生β淀粉样肽（pGlu-Aβ）的N末端焦谷氨酸与毒性淀粉样蛋白斑块的形成有关，因此可能参与了阿尔茨海默氏病（AD）的发病机理。我们基于优选底物Aβ3E-42的拟议结合模式设计了谷氨酰环化酶（QC）抑制剂库。一项体外结构-活性关系研究确定了几种出色的QC抑制剂，与已知的QC抑制剂相比，其效能提高了5至40倍。在AD的小鼠模型中测试时，化合物212显着降低了焦状Aβ和总Aβ的大脑浓度，并恢复了认知功能。这种强大的Aβ降低作用是通过将一个额外的结合区并入我们先前建立的药效团模型中而实现的，从而导致在QC结合位点与Glu327的羧酸酯基团发生强相互作用。我们的研究为设计新型QC抑制剂作为AD的潜在治疗方法提供了有用的见识。

  ABSTRACT Nitroarenes are reduced to the corresponding aniline derivatives using iron or zinc under mild conditions under microwave heating conditions. Mild acidity is provided by ammonium chloride in an aqueous methanol medium. The conditions are tolerant to other functional groups, with the exception of bromoalkyl derivatives, which yield complex reaction mixtures; otherwise, yields are generally quite

  摘要 在微波加热条件下，在温和条件下使用铁或锌将硝基芳烃还原为相应的苯胺衍生物。温和的酸性由氯化铵在甲醇水溶液中提供。这些条件对其他官能团具有耐受性，但溴代烷基衍生物除外，它们会产生复杂的反应混合物；否则，产量通常相当高（80-99%）。图形概要
• A biomolecule-compatible visible-light-induced azide reduction from a DNA-encoded reaction-discovery system

  Using a system that accelerates the serendipitous discovery of new reactions by evaluating hundreds of DNA-encoded substrate combinations in a single experiment, we explored a broad range of reaction conditions for new bond-forming reactions. We discovered reactivity that led to a biomolecule-compatible, Ru(II)-catalysed azide-reduction reaction induced by visible light. In contrast to current azide-reduction methods, this reaction is highly chemoselective and is compatible with alcohols, phenols, acids, alkenes, alkynes, aldehydes, alkyl halides, alkyl mesylates and disulfides. The remarkable functional group compatibility and mild conditions of the reaction enabled the azide reduction of nucleic acid and oligosaccharide substrates, with no detectable occurrence of side reactions. The reaction was also performed in the presence of a protein enzyme without the loss of enzymatic activity, in contrast to two commonly used azide-reduction methods. The visible-light dependence of this reaction provides a means of photouncaging functional groups, such as amines and carboxylates, on biological macromolecules without using ultraviolet irradiation. A DNA-encoded reaction discovery system has revealed reactivity that led to the development of a visible-light-induced, biomolecule-compatible azide reduction. This reaction exhibits remarkable chemoselectivity and can be performed on oligonucleotide and oligosaccharide substrates, and in the presence of a protein enzyme, without undesired side reactions or loss of enzyme activity.

  利用一个通过单次实验评估数百种DNA编码底物组合来加速偶发发现新反应的系统，我们探索了大量反应条件用于形成新键的反应。我们发现了一种与生物分子兼容的、由可见光诱导的、以Ru(II)为催化剂的叠氮化物还原反应。与目前的叠氮化物还原方法相比，该反应具有高度的化学选择性，并且与醇、酚、酸、烯烃、炔烃、醛、烷基卤化物、烷基甲磺酸酯和二硫化物等官能团兼容。该反应出色的官能团兼容性和温和的条件使得能够对核酸和寡糖底物进行叠氮化物还原，且没有检测到副反应的发生。与两种常用的叠氮化物还原方法不同，该反应在存在蛋白质酶的情况下进行，且没有失去酶活性。该反应对可见光的依赖性提供了一种在不使用紫外线照射的情况下对生物大分子上的功能团（如胺和羧酸盐）进行光控释放的方法。DNA编码的反应发现系统揭示了导致发展可见光诱导的、与生物分子兼容的叠氮化物还原反应的活性。该反应表现出卓越的化学选择性，并且可以在寡核苷酸和寡糖底物上进行，并且在存在蛋白质酶的情况下，没有不希望的副反应或酶活性的损失。
