  摘要：

  基于两个异构的噻吩并噻吩供体和七个具有各种电子性质的受体，已经设计并方便地合成了十四个新的D-π-A推挽发色团。与已知的噻吩并噻吩推挽分子相反，制备的小发色团被证明是有机材料，具有易于调节的热，电化学和（非线性）光学特性。还已经表明，小的结构变化可以导致显着改善/变化的基本性能。在系统开发的一系列推挽分子中阐明了非常详细的结构与性质的关系，这可作为设计基于融合噻吩骨架的新D-π-A分子的有用指南。

  Discovery of Potent and Orally Bioavailable GPR40 Full Agonists Bearing Thiophen-2-ylpropanoic Acid Scaffold

  摘要：

  The free fatty acid receptor GPR40 is predominantly expressed in pancreatic beta-cells and enhances insulin secretion in a glucose dependent manner. Therefore, GPR40 agonists are possible novel insulin secretagogues with reduced or no risk of hypoglycemia for the treatment of type 2 diabetes mellitus (T2DM). Chemically and structurally diverse GPR40 agonists with high safety are pursued for the clinical development of GPR40-based pharmacotherapeutics. Herein we report our design and discovery of a new chemotype of GPR40 agonists free of the typical phenylpropanoic acid scaffold. The thiophen-2-ylpropanoic acid containing GPR40 modulators functioned as full agonists with high-efficacy response (E-max) and reduced lipophilicity. Significantly, the lead compound in this series, (R)-7k, exhibited more potent in vitro glucose-stimulated insulin secretion and in vivo glucose-lowering effects (10 mg/kg, po) than the GPR40 partial agonist TAK-875, which was once in phase III clinical trials, and high selectivity over the relevant receptors GPR120 and PPAR gamma.

  A series of 5-substituted thieno[2,3-b]- and thieno[3,2-b)- and thieno[3,2-b)thiophene-2-sulfonamides was prepared and evaluated for topical ocular hypotensive activity in glaucoma models. The 5-substituents were varied to maximize both inhibitory potency against carbonic anhydrase and water solubility. At the same time, these substituents were varied in order to obtain compounds with the appropriate

  Three series of novel push–pull 5-arylthieno[3,2-b]thiophene derivatives functionalized with potent electron-withdrawing terminal moieties have been synthesized in moderate to excellent yields by Suzuki coupling followed by Knoevenagel condensation. These novel chromophores show intense absorption in the near-UV region through to the orange visible region, related to a strong intramolecular charge-transfer
