  亚氨基硫醚作为硫化氢的供体：从气体递质释放到血管效应

  摘要：

  气体递质硫化氢（H 2 S）是心血管稳态的重要调节剂，其缺乏在病因上与许多心血管疾病有关。因此，对能够释放H 2 S的原始部分的研究代表了药物发现的及时问题。在这项工作中，我们开发了亚氨基硫醚（ITE）的集合，这些亚硫醚具有H 2 S释放特性，并且对大鼠主动脉环产生血管松弛作用。选择导数4和11作为慢速和快速H 2的代表S个供体分别使基础冠状动脉血流完全恢复，从而恢复了AngII诱导的离体大鼠心脏的作用。此外，对人主动脉平滑肌细胞（HASMC）的研究表明，膜超极化作用与H 2 S的细胞内生成密切相关。综上所述，所获得的结果支持ITE 4和ITE 11作为新的药理学手段，并且有效且有效。用于心血管药物发现的创新型H 2 S供体。

• Single-Step Microwave-Mediated Synthesis of Oxazoles and Thiazoles from 3-Oxetanone: A Synthetic and Computational Study

  The direct microwave‐mediated condensation between 3‐oxetanone and primary amides and thioamides has delivered moderate to good yields of (hydroxymethyl)oxazoles and (hydroxymethyl)thiazoles. The reactions use a sustainable solvent and only require short reaction times. These are highly competitive methods for the construction of two classes of valuable heteroarenes, which bear a useful locus for further

  3-氧杂环丁酮与伯酰胺和硫代酰胺之间的直接微波介导缩合反应产生了中等到良好的（羟甲基）恶唑和（羟甲基）噻唑收率。反应使用可持续的溶剂，只需要很短的反应时间。这些是构建两类有价值的杂芳烃的高度竞争性方法，它们具有进一步阐明的有用位置。电子结构计算表明，事件的顺序涉及sp 3处硫属元素原子的攻击碳和烷基-氧裂解。清楚地表明了酸催化的关键作用，并证明了酸强度的重要性。计算的势垒也与所观察到的硫酰胺和酰胺反应性顺序完全一致。自发的开环涉及适度的CO裂解，减缓了应力释放的程度。在酸催化的途径上，CO的裂解仍然不太广泛，但是通过羧酸催化剂，质子转移到核反应堆中的进展非常快，而基本上是用甲磺酸完成的。

  An efficient and facile synthesis of 3,5-di(hetero)aryl-1,2,4-thiadiazoles by oxidative dimerisation of thioamides by grinding with NBS under solvent-free conditions at room temperature has been developed. The efficiency of this reaction was demonstrated by the compatibility with trifluoromethyl, methyl, methoxy, chloro, pyridyl and thienyl groups. This method has notable advantages in terms of short reaction times, high yields and is a more practical alternative to the existing methods to access these compounds.

• Design, synthesis and Structure–activity relationship studies of new thiazole-based free fatty acid receptor 1 agonists for the treatment of type 2 diabetes

  The free fatty acid receptor 1 (FFA1/GPR40) has attracted interest as a novel target for the treatment of type 2 diabetes. Several series of FFA1 agonists including TAK-875, the most advanced compound terminated in phase III studies due to concerns about liver toxicity, have been hampered by relatively high molecular weight and lipophilicity. Aiming to develop potent FFA1 agonists with low risk of

  游离脂肪酸受体1（FFA1 / GPR40）作为治疗2型糖尿病的新靶标已引起人们的关注。相对较高的分子量和亲脂性阻碍了包括FAK1激动剂在内的数个系列的FFA1激动剂（由于对肝毒性的担忧而在III期研究中终止的最先进的化合物）。为了通过降低亲脂性来开发具有低肝毒性风险的有效FFA1激动剂，TAK-875的中间苯基被11个极性五元杂芳族化合物所取代。随后，对SAR的系统探索和分子建模的应用导致了化合物44的鉴定，它是一种出色的FFA1激动剂，在正常和2型糖尿病小鼠中均具有强大的降血糖作用，即使在两倍摩尔的TAK-875剂量下也具有低血糖风险和肝毒性。同时，指出了两个重要发现。首先，我们的噻唑系列中的甲基占据了一个小的疏水亚口袋，与TAK-875没有相互作用。此外，激动活性显示与噻唑核心和末端苯环之间的二面角具有良好的相关性。这些结果促进了对配体结合口袋的了解，并可能有助于设计更有希望的FFA1激动剂。
