  Allosteric Modulation of Protein Arginine Methyltransferase 5 (PRMT5)

  摘要：

  Protein arginine methyltransferase 5 (PRMT5) belongs to a family of enzymes that regulate the posttranslational modification of histones and other proteins via methylation of arginine. Methylation of histones is linked to an increase in transcription and regulates a manifold of functions such as signal transduction and transcriptional regulation. PRMT5 has been shown to be upregulated in the tumor environment of several cancer types, and the inhibition of PRMT5 activity was identified as a potential way to reduce tumor growth. Previously, four different modes of PRMT5 inhibition were known-competing (covalently or non-covalently) with the essential cofactor Sadenosyl methionine (SAM), blocking the substrate binding pocket, or blocking both simultaneously. Herein we describe an unprecedented conformation of PRMT5 in which the formation of an allosteric binding pocket abrogates the enzyme's canonical binding site and present the discovery of potent small molecule allosteric PRMT5 inhibitors.

  乙炔基苯并酮酮的直接光激发：炔化反应光催化的替代方案*。

  摘要：

  乙炔基苯并氧杂环酮 (EBX) 通常用作光催化炔基化反应中的自由基捕获剂。在此，我们报道芳基取代的 EBX 试剂可以通过可见光照射直接激活。它们既可以作为氧化剂，也可以作为自由基捕获剂，减轻了一些已报道的 EBX 介导过程中对光催化剂的需求，包括脱羧和脱硼炔基化、烯酰胺的氧炔基化和 THF 的 CH 炔基化。此外，该方法还可应用于从叔醇通过稳定的草酸盐以及从叔胺通过芳基亚胺合成炔化季中心。还开发了使用 4CzIPN 作为有机染料的光催化工艺用于草酸盐的脱氧炔基化。

  Visible‐light‐induced heterogeneous photocatalysis for decarboxylative alkynylation has been performed. The using of cheap, metal‐free and recyclable graphitic carbon nitride (g‐C3N4) as the photoredox catalyst in the process enables the facile transformation of a variety of carboxylic acids into structurally diverse alkyne‐containing molecular architectures under mild and environmentally‐benign conditions

  可见光诱导的非均相光催化脱羧炔基反应。使用便宜，无金属且可回收的石墨氮化碳（g ‐ C 3 N 4）作为该过程中的光氧化还原催化剂，可以在温和和环境友好的条件下将多种羧酸轻松转化为结构多样的含炔分子结构。明显地，反应系统的非均质性质允许催化剂在多次运行中的回收和再利用而不损失反应性。光催化反应也可以以连续流动的方式进行并按比例放大至克级。此外，该策略在未活化烯烃的1，2氨基炔基化中的应用进一步凸显了该策略的制备能力。

  radical‐mediated C−H alkynylation reaction of inactivated alkanes was described. The reaction features mild operation condition and wide substrate scope, and affords the corresponding products in moderate to good yields. Notably, The presence of 4‐cyanopyride N‐oxide was key to the success of the reaction. Cyclohexane are more easily to be functionalized in this reaction than toluene, which could be rationally

  描述了一个有趣的吡啶-硼基自由基介导的灭活烷烃的CH炔基化反应。该反应具有温和的操作条件和广泛的底物范围，并以中等至良好的产率提供了相应的产物。值得注意的是，4-氰基吡啶N-氧化物的存在是反应成功的关键。环己烷比甲苯更容易在该反应中被官能化，这可以用极性匹配原理合理地解释。
• A Convenient Synthesis of 1,2-Dithietes and 1,2-Dithioxo Compounds Stabilized by Buttressing and Resonance Effects, Respectively, by Sulfuration of Alkynes with Elemental Sulfur

  日期：1993.2

  Sulfuration of a series of alkynes by elemental sulfur was investigated. Alkynes carrying highly bulky substituents, 2,2,5,5-tetramethyl-3-hexyne (6a), 1,2-di-(1-adamantyl)ethyne (6b), 3,3-dimethyl-1-phenyl-1-butyne (6c), and 1-(1-adamantyl)-2-phenylethyne (6d), reacted with sulfur to give the corresponding stable 1,2-dithietes 7a—d in 46—65% yields. Less hindered alkynes reacted with sulfur to afford 1,4-dithiins and thiophenes as the final products which were derived from the initial products, 1,2-dithietes, via their tautomerization to the corresponding 1,2-dithioxo compounds, while extremely congested alkynes failed to react with sulfur even under forcing conditions. On the other hand, ynamines, a typical electron-rich alkyne, 1-diethylamino-2-phenylthioethyne (6o), 1-diethylamino-2-phenylselenoethyne (6p), and tetraethylethynediamine (6q) were sulfurated under milder conditions to afford resonance-stabilized 1,2-dithioxo compounds 19o—q as the principal products. Mechanism of the formation of 1,2-dithietes, 1,2-dithioxo compounds, and other products is discussed.

  用元素硫对一系列炔烃进行硫化反应进行了研究。带有高度庞大取代基的炔烃，2,2,5,5-四甲基-3-己炔(6a)、1,2-双(1-金刚烷基)乙炔(6b)、3,3-二甲基-1-苯基-1-丁炔(6c)和1-(1-金刚烷基)-2-苯乙炔(6d)，与硫反应得到相应的稳定1,2-二硫杂环己烯7a—d，产率为46—65%。取代基较少的炔烃与硫反应得到1,4-二硫杂苯和噻吩作为最终产物，这些产物由初始产物1,2-二硫杂环己烯通过其互变异构化形成相应的1,2-二硫氧化物得到，而极其拥挤的炔烃即使在强制条件下也无法与硫反应。另一方面，典型的富电子炔烃亚胺，1-二乙氨基-2-苯硫乙炔(6o)、1-二乙氨基-2-苯硒乙炔(6p)和四乙基乙炔二胺(6q)，在较温和的条件下被硫化得到共振稳定的1,2-二硫氧化物19o—q作为主要产物。讨论了1,2-二硫杂环己烯、1,2-二硫氧化物和其他产物的形成机理。

  Visible‐light‐induced photocatalytic decarboxylative alkynylations of carboxylic acids have been developed for the first time. The reaction features extremely mild conditions, broad substrate scope, and avoids additional oxidants. Importantly, a decarboxylative carbonylative alkynylation has also been carried out in the presence of carbon monoxide (CO) under photocatalytic conditions, which affords

  C(sp)−H silylation of a wide range of terminal alkynes with hydrosilanes by using a combination of B(C6F5)3 and an organic base such as triethylenediamine (DABCO). This protocol constitutes the first example of boron‐catalyzed C(sp)−H functionalization, offering a convenient route for the synthesis of a variety of alkynylsilanes. Experimental and computational studies have revealed that DABCO plays two

  过渡金属催化的有机化合物的CH官能化已被证明是有机合成中有用的原子效率策略。相比之下，迄今为止，对于CHH功能化的基于主族元素的催化过程仍未得到充分研究。本文报道的是通过使用B（C 6 F 5）3的组合，各种末端炔烃与氢硅烷的催化C（sp）-H甲硅烷基化反应和有机碱，例如三乙二胺（DABCO）。该协议构成了硼催化的C（sp）-H功能化的第一个例子，为合成各种炔基硅烷提供了一条便捷的途径。实验和计算研究表明，DABCO在此催化转化中起着两个至关重要的作用（刘易斯碱和布朗斯台德碱）。
