  A series of novel pyridazinone derivatives were designed and synthesized by replacing 4‐(tert‐butyl)phenyl moiety of pyridaben with 2‐phenylthiazole or oxazole fragments via activity substructure connecting approach. The structures of all target compounds were characterized through NMR, MS, and elemental analysis. Bioassay results exhibit that most compounds showed potent bioactivities against Aphis

  通过活性亚结构连接方法，用2-苯基噻唑或恶唑片段取代了哒嗪的4-（叔丁基）苯基部分，设计并合成了一系列新型的哒嗪酮衍生物。所有目标化合物的结构均通过NMR，MS和元素分析表征。生物测定的结果表明，大多数化合物显示出对Fabs，Tetranychus urticae，Erysiphe graminis和/或Puccinia polysora的有效生物活性。在新合成的化合物中，2-（叔丁基）-4-氯5-（（（（2-苯基噻唑-4-基）甲基）硫基）哒嗪-3（2 H）-one（12b）对Fab表现出明显的杀虫活性。它的LC 50值（2.73 mg / L）比吡虫本（5.46 mg / L）好，尽管比吡虫啉（0.51 mg / L）低。除具有非凡的杀虫活性外，化合物12b在体内500 mg / L时对多聚磷也具有96.9％的杀真菌活性，显着优于吡达本（50.0％），但略低于戊唑醇（100％）。本文讨论

  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.

  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。

  Diflumetorim is a member of pyrimidinamine fungicides that possess excellent antifungal activities. Nevertheless, as reported that the activity of diflumetorim to corn rust (Puccinia sorghi) was not ideal (EC50 = 53.26 mg/L). Herein, a series of novel pyrimidinamine derivatives containing phenyl-thiazole/oxazole moiety were designed based on our previous study and the structural characteristics of

  地氟美林是嘧啶胺杀菌剂的成员，具有优异的抗真菌活性。然而，据报道，双氟甲蝶呤对玉米锈病（高粱）的活性并不理想（EC50 = 53.26 mg / L）。在此，根据我们先前的研究和双氟甲草胺的结构特征，设计合成了一系列含有苯基-噻唑/恶唑部分的新型嘧啶胺衍生物，并对其进行了生物测定并进行了生物测定，以发现具有优异抗真菌活性的新型杀菌剂。在这些化合物中，T18具有最佳的杀真菌活性，分别对高粱P.orghi和E. graminis的EC50值为0.93 mg / L和1.24 mg / L，具有明显优于商业杀真菌剂diflumetorim，tebuconazole和flusilazole的防治效果。细胞的细胞毒性结果表明，化合物T18的毒性低于双氟甲蝶呤。此外，DFT计算表明，苯基噻唑/恶唑部分在活性提高中起着不可争辩的作用，这将有助于将来设计和开发更有效的化合物。
