  Base-Mediated Carboxylation of Unprotected Indole Derivatives with Carbon Dioxide

  摘要：

  A simple and straightforward method for the preparation of indole-3-carboxylic acids was discovered through the direct carboxylation of indoles with atmospheric pressure of carbon dioxide (CO2) under basic conditions. The key for the reaction was found to be the use of a large excess of LiO'Bu as a base to suppress the undesired decarboxylation side reaction.

  吲哚胺 2,3-双加氧酶 1 抑制剂的设计和合成及其作为抗肿瘤剂的应用评价

  摘要：

  吲哚胺 2,3-双加氧酶 (IDO) 1 是调节色氨酸代谢的关键酶，是阻断肿瘤免疫逃逸的重要靶点。在这项研究中，我们通过将各种片段或配体连接到吲哚或苯基咪唑支架上以提高与 IDO1 的结合，设计了四个系列的化合物作为潜在的 IDO1 抑制剂。合成了这些化合物，并评估了它们对 IDO1 和色氨酸 2,3-双加氧酶的抑制活性。还测定了化合物对两种肿瘤细胞系的细胞毒性。具有苯基咪唑支架的两种化合物（DX-03-12 和 DX-03-13）显示出有效的 IDO1 抑制，IC50 值为 0.3–0.5 μM。这两种 IDO1 抑制剂显示出低细胞毒性，这表明它们可能通过免疫调节发挥抗肿瘤作用。通过确定体内药代动力学特征和抗肿瘤功效，进一步研究了化合物 DX-03-12。药代动力学研究表明，DX-03-12 在小鼠体内具有令人满意的特性，吸收迅速、血浆清除率中等（约 36% 的肝血流量）、可接受的半衰期（约

  An efficient and environmentally benign Cu-mediated method was developed for direct cascade C–H/N–H annulation to construct polyheterocyclic indoloquinoline scaffolds. This method highlights an emerging strategy for transforming inert C–H bonds into versatile functional groups in organic synthesis and provides a new versatile approach for the efficient synthesis of indolo[3,2-c] and [2,3-c]quinoline

This simple protocol, which affords the desired products with CO2 and water as the coproducts, can be achieved under mild conditions without the need for base or other additives in water.

  Disclosed herein are a new indole carboxylic acid bispyridyl carboxamide derivative, a preparation method thereof, and a composition for prevention or treatment of obesity, urinary disorders, and CNS disorders, containing the same as an active ingredient. Because the indole carboxylic acid bispyridyl carboxamide derivatives according to the present invention have high affinity for 5-HT 2c receptors, act selectively on the 5-HT 2c receptors, the derivatives rarely have adverse effects caused by other receptors. Because the derivatives effectively inhibit serotonin activity, they may be useful for treatment or prevention of obesity; urinary disorders such as urinary incontinence, premature ejaculation, erectile dysfunction, and prostatic hyperplasia; CNS disorders such as depression, anxiety, concern, panic disorder, epilepsy, obsessive-compulsive disorder, migraine, sleep disorder, withdrawal from drug abuse, Alzheimer's disease, and schizophrenia, associated with 5-HT 2c receptors.
