• 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。

  Nineteen bisthiazoles were tested in order to assess their anti-inflammatory and antioxidant properties. First, we evaluated the in vitro direct antioxidant capacity of the bisthiazoles using the DPPH radical scavenging method. Then, the anti-inflammatory effect was tested in acute rat experimental inflammation by measuring the acute phase bone marrow response, the phagocytic capacity and the serum nitro-oxidative stress status. Although none of the substances showed significant direct antioxidant potential in the DPPH assay, most of them improved serum oxidative status, when administered to rats with inflammation. Four of the bisthiazoles proved to have good anti-inflammatory properties, similar or superior to that of equal doses meloxicam.

  测试了19种双硫杂环烷以评估其抗炎和抗氧化特性。首先，我们使用DPPH自由基清除法评估了双硫杂环烷的体外直接抗氧化能力。然后，通过测量急性期骨髓反应、吞噬能力和血清氮-氧化应激状态，在急性大鼠实验性炎症中测试了其抗炎效果。尽管在DPPH实验中没有任何物质显示出明显的直接抗氧化潜力，但在给予患有炎症的大鼠时，大多数双硫杂环烷改善了血清氧化状态。其中四种双硫杂环烷显示出良好的抗炎特性，与同等剂量的美洛昔康相似或更优。

  Bromodomain and extra-terminal (BET) is a promising therapeutic target for various hematologic cancers. We used the BRD4 inhibitor compound 13 as a lead compound to develop a variety of compounds, and we introduced diverse groups into the position of the compound 13 orienting toward the ZA channel. A series of compounds (14–23, 38–41, 43, 47–49) bearing triazolopyridazine motif exhibited remarkable

  Bromodomain and extra-terminal (BET) 是各种血液癌症的有希望的治疗靶点。我们使用BRD4抑制剂化合物13作为先导化合物开发了多种化合物，我们在化合物13朝向ZA通道的位置引入了不同的基团。的一系列化合物的（14-23，38-41，43，47-49）轴承三唑并哒嗪基序表现出显着的BRD4蛋白抑制活性。其中，化合物39抑制BRD4(BD1)蛋白的IC 50为0.003 μM，优于先导化合物13。同时，化合物39具有 抗 U266 癌细胞的抗增殖活性，IC 50 = 2.1 μM。另一方面，化合物39可以阻止肿瘤细胞进入G0/G1期并诱导细胞凋亡，这与其抑制细胞增殖的结果一致。生物学和生化数据表明，BRD4 蛋白可能是一个治疗靶点，而化合物39是进一步开发的极好先导化合物。
