  Synthesis, Spectra, and Theoretical Investigations of the Triarylamines Based on 6H-Indolo[2,3-b]quinoxaline

  摘要：

  Triarylamines containing a 6H-indolo[2,3-b]quinoxaline core and aromatic units such as phenyl, naphthyl, pyrene, anthracene, or fluorene have been synthesized by employing palladium-catalyzed C-N and C-C coupling reactions and characterized by optical absorption and emission spectra, electrochemical behavior, and thermal studies. Even though the electronic absorption spectra of the compounds were influenced by the nature of the peripheral amines, the emission spectra indicated close similarity for the excited states in these compounds. For the derivatives in which the amines were directly anchored on the 6H-indolo[2,3-b]quinoxaline nucleus, the emission appeared to be dominated by the state localized on the 6H-indolo[2,3-b]quinoxaline chromophore, while in the compounds containing the extended conjugation the fluorescence originated from the polyaromatic linker. The compounds displayed green or yellow emission depending on the nature of the amine segment. All of the dyes displayed one-electron quasi-reversible oxidation couple in the cyclic voltammograms, which is attributable to the oxidation of the peripheral amines at the 6H-indolo[2,3-b]-quinoxaline core. An additional one-electron oxidation process observable at the high positive potentials for the compounds 7 and 8 probably arises from the oxidation of the arylthiophene segment. The enhanced thermal stability and relatively higher glass transition temperatures observed for these compounds were attributed to the presence of dipolar 6H-indolo[2,3-b]quinox. aline segment. The origin of the optical spectra and the trends observed therein were rationalized using TDDFT simulations.

  吲哚喹喔啉衍生物作为有前景的多功能抗阿尔茨海默病药物

  摘要：

  摘要 为了对抗阿尔茨海默病等具有复杂发病机制的疾病，多靶点定向配体的开发已成为一种有前途的药物发现方法。在我们致力于开发针对阿尔茨海默病的多靶点定向配体的过程中，设计并合成了一系列吲哚喹喔啉衍生物。体外胆碱酯酶抑制研究表明，所有合成的化合物都表现出中等至良好的胆碱酯酶抑制活性。6-(6-(Piperidin-1-yl)hexyl)-6 H -indolo[2,3- b ]quinoxaline 9f被确定为最有效和选择性的 BuChE 抑制剂 (IC 50= 0.96 µM，选择性指数 = 0.17)，与商业批准的参考药物多奈哌齐 (IC 50 = 1.87 µM)相比，BuChE 抑制活性高出 2 倍。此外，化合物9f还具有自诱导 Aβ 1-42聚集抑制活性（在 50 μM 浓度下抑制 51.24%）。该系列的一些化合物也显示出适度的抗氧化活性。为了解化合物9f的推定结合模式，进行了分子
