  Diflunisal类似物稳定运甲状腺素蛋白的天然状态。有效抑制淀粉样蛋白生成。

  摘要：

  合成了FDA批准的非甾体抗炎药diflunisal的类似物，并将其评估为转甲状腺素蛋白（TTR）聚集（包括淀粉样蛋白原纤维形成）的抑制剂。对于26种化合物观察到高抑制活性。其中，八种在人血浆中对TTR表现出优异的结合选择性（结合化学计量比> 0.50，每个TTR四聚体理论上最多结合有2.0种抑制剂）。生物物理研究表明，这八种抑制剂可在168小时的时间内显着减慢四聚体的解离（淀粉样蛋白生成的速率决定步骤）。这似乎是通过基态稳定化来实现的，这提高了四聚体解离的动力学势垒。这八种抑制剂对WT TTR的动力学稳定作用进一步得到证实，淀粉样蛋白原纤维形成的速率随抑制剂浓度（pH 4.4）的增加而降低。TTR.18（2）和TTR.20（2）配合物的X射线共晶体结构揭示了18和20在TTR结合位点以相反的方向结合。将氟从18的间位移至20的邻位可逆转结合方向，使20的亲水性芳环在外部结合袋中取向，其中羧

  A series of derivatives of (phenylsulfanyl)benzoic acids bearing quinoline, 2,4-dihydroxy-3-propylacetophenone and 2,4-difluorobiphenyl moieties were prepared and their antileukotrienic activities evaluated. Some of the compounds were found to display multiple antileukotrienic effect in the inhibition of LTB₄biosynthesis, binding to LTD₄and LTB₄receptors, superior to the standards (zileuton and zafirlukast) used. The compounds had an antiinflammatory effect, manifested with quinoline derivatives by a significant inhibition of bronchospasm induced by LTD₄and/or albumin. The results of regression analysis correspond to the observation that the most active compounds belong to quinoline derivatives with the lowest lipophilicity. X-ray analysis of the quinoline compounds revealed that an intramolecular hydrophobic interaction of their aromatic rings does not occur in the solid state.
