• 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。

  chromone derivatives containing substituted pyrazole were designed and synthesized. Preliminary bioassays showed that most of the synthesized compounds exhibited good nematicidal activity in vivo against Meloidogyne incognita at 10 mg/L. Among the tested compounds, A10 and A11 exhibited 100% inhibition rates. In addition, the molecular docking results indicated that both compound A10 and A11 interacts

  摘要设计合成了一系列含取代吡唑的色酮衍生物。初步的生物测定表明，大多数合成的化合物在体内对10 mg / L的根结线虫都有良好的杀线虫活性。在测试的化合物中，A10和A11表现出100％的抑制率。此外，分子对接结果表明，化合物A10和A11都通过氢键和π-π堆积与AChE的氨基酸残基Tyr121，Trp279，Tyr70，Trp84和Phe330相互作用。这项研究表明，可以进一步优化含有色酮的取代吡唑支架，以探索新型的，具有高生物活性的杀线虫剂。

  crystal structures of N-terminally capped peptides. Furthermore, the structure–activity relationship of a bis(aryl) ether C-terminal capping group mimicking dipeptide interactions was probed through ring substitutions, allowing increased complementarity with the primary hydrophobic pocket. This study further validates REPLACE as an effective strategy for converting peptidic compounds to more pharmaceutically

  药物发现的一个主要挑战是开发和改进靶向蛋白质-蛋白质相互作用的方法。用于生成蛋白质-蛋白质相互作用抑制剂的 REPLACE（通过计算富集替代部分配体替代物）策略的进一步示例表明，它可用于优化关键决定因素的片段替代物，以有效的方式将它们组合起来，并已实现用于靶向细胞周期蛋白调节亚基上的细胞周期蛋白依赖性激酶 2 (CDK2) 底物募集位点的化合物。取代关键电荷-电荷相互作用的苯基杂环等排体为结合细胞周期蛋白凹槽提供了新的结构见解。特别是，这些结果揭示了在 N 端加帽肽的晶体结构中观察到的 H 键的关键贡献。此外，通过环取代探测了模拟二肽相互作用的双（芳基）醚 C 端封端基团的构效关系，从而增加了与主要疏水口袋的互补性。该研究进一步验证了 REPLACE 作为将肽类化合物转化为药学相关性更强的化合物的有效策略。
