  荧光香豆素-苯并[ b ]噻吩1，1-二氧化物缀合物作为靶向线粒体的抗肿瘤STAT3抑制剂的发现

  摘要：

  STAT3已被广泛研究为潜在的抗肿瘤靶标。尽管关于调节STAT3的研究主要集中在抑制Tyr705残基上的STAT3磷酸化，但是STAT3蛋白的Ser727残基上的磷酸化也与STAT3蛋白的线粒体导入密切相关。N，N-二乙基-7-氨基香豆素是一种荧光的线粒体靶向探针。在这项研究中，通过将N，N-二乙基-7-氨基香豆素荧光团与苯并[ b ]噻吩1，1-二氧化物部分相连，开发了一系列STAT3抑制剂。所有设计的化合物均显示出对癌细胞有效的抗增殖活性。代表性化合物7a主要通过荧光可见的线粒体中积累。化合物7a在Tyr705和Ser727残基均抑制STAT3磷酸化。化合物7a抑制STAT3磷酸化，而对STAT1，JAK2，Src和Erk1 / 2的磷酸化水平没有影响，表明化合物7a具有良好的选择性。此外，化合物7a下调STAT3靶基因Bcl-2和Cyclin D1的表达，增加ROS的产生并显着降低线

  identified and extended a novel family of 2-(substituted phenyl)-benzimidazole inhibitors of IgE response. Pharmacological activity depends on an intact phenylbenzimidazole-bis-amide backbone, and is optimized by the presence of lipophilic terminal groups composed of either bis cycloalkyl or combinations of aliphatic and halogen-substituted aromatic groups. These compounds also inhibit IL-4 and IL-5 responses

  传统上，过敏和哮喘的药物治疗重点放在过敏级联反应的效应分子上，而忽略了在其发展中起早期作用的靶标。由于IgE对特应性疾病的扩展至关重要，因此我们确定并扩展了IgE反应的2-（取代苯基）-苯并咪唑抑制剂的新家族。药理活性取决于完整的苯基苯并咪唑-双酰胺主链，并通过存在由双环烷基或脂族和卤素取代的芳族基团组成的亲脂性端基来优化药理活性。这些化合物还抑制T细胞中的IL-4和IL-5应答以及B细胞上的CD23表达，其效力与其抑制IgE相似。
