  吲哚嗪衍生物作为α-7nAChR激动剂的合成及生物活性

  摘要：

  人α7烟碱乙酰胆碱受体（nAChR）是治疗伴有认知障碍的精神分裂症的有前途的治疗靶标。在本文中，我们报告了一系列针对α7nAChR的吲哚嗪衍生物的合成和激动活性。结果表明，所有合成的化合物均对α7nAChR具有亲和力，并且某些化合物具有很强的激动活性，特别是大多数活性激动剂均显示出比对照EVP-6124更高的效力。对接和结构-活性关系研究为开发更有效的新型α7nAChR激动剂提供了见识。

  Catalyst-Free Annulation of 2-Pyridylacetates and Ynals with Molecular Oxygen: An Access to 3-Acylated Indolizines

  摘要：

  A catalyst and additive-free annulation of 2-pyridylacetates and ynals under molecular oxygen was the first developed, affording 3-acylated indolizines in good to excellent yields. Molecular oxygen was used as the source of the carbonyl oxygen atom in indolizines. This approach was compatible with a wide range of functional groups, and especially it has been successfully extended to unsaturated double bonds and triple bonds, which were difficult to prepare by previous methods in a single step.

The X-ray diffraction analysis of the compound 4b was also carried out. Further, a safety study (in silico and in vitro) demonstrated no toxicity for these compounds. Thus, the indolizines warrant further development

  摘要 筛选了一系列 1,2,3-三取代的吲哚嗪（2a-2f、3a-3d和4a-4c）对敏感 H37Rv 和耐多药 (MDR)结核分枝杆菌的体外全细胞抗结核活性(MTB) 菌株。化合物2b–2d、3a–3d和4a–4c对 H37Rv-MTB 菌株具有活性，最小抑制浓度 (MIC) 范围为 4 到 32 µg/mL，而吲哚嗪4a–4c具有乙基酯基团苯甲酰基环的 4 位也表现出抗 MDR-MTB 活性（MIC = 16–64 µg/mL）。电脑模拟对接研究表明，烯酰-酰基载体蛋白还原酶（InhA）和邻氨基苯甲酸磷酸核糖转移酶是吲哚嗪的潜在分子靶标。还进行了化合物4b的X射线衍射分析。此外，一项安全性研究（计算机和体外）证明这些化合物没有毒性。因此，indolizine 需要进一步开发，并且可能代表一类新的有前途的 InhA 抑制剂和多靶向药物，以对抗药物敏感和耐药的 MTB 菌株。

  An iodine-mediated oxidative cyclization reaction between 2-(pyridin-2-yl)acetate derivatives and different alkynes has been developed, which provides regioselective and chemoselective syntheses of multiply substituted indolizines under modified reaction conditions. Plausible mechanisms have been proposed to explain the selective syntheses of indolizines. This protocol can be also applied to the stepwise
