  基于喹诺酮支架的 DC-SIGN 类药物抑制剂

  摘要：

  DC-SIGN（树突状细胞特异性细胞间粘附分子-3-抓取非整联蛋白）是一种在免疫细胞上表达的模式识别受体，参与识别各种病原体（包括 HIV、埃博拉病毒和 SARS-CoV）上存在的碳水化合物特征-2。因此，开发阻断 DC-SIGN 碳水化合物结合位点的抑制剂可以产生一种有价值的工具来研究该受体在多种传染病中的作用。在此，我们使用 4-喹诺酮作为支架进行了基于片段的配体设计。我们合成了一个包含 61 种化合物的库，使用 STD 报告基因分析对 DC-SIGN 进行了筛选，并使用基于蛋白质的1 H– 15验证了这些数据NHSQC 核磁共振。基于构效关系数据，我们证明 2 位或 3 位的乙氧基羰基或二甲基氨基羰基有利于 DC-SIGN 结合活性，尤其是与 7 位或 8 位的氟、乙氧基羰基或二甲基氨基羰基组合。此外，我们证明这些喹诺酮类药物可以变构调节碳水化合物结合位点，这为这一具有挑战性的蛋白质靶标提供了另一种方法。

  Due to the emerging role of protein kinase CK2 as a molecule that participates not only in the development of some cancers but also in viral infections and inflammatory failures, small organic inhibitors of CK2, besides application in scientific research, may have therapeutic significance. In this paper, we present a new class of CK2 inhibitorss3-carboxy-4(1H)-quinolones. This class of inhibitors has been selected via receptor-based virtual screening of the Otava compound library. It was revealed that the most active compounds, 5,6,8-trichloro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid (7) (IC50 = 0.3 mu M) and 4-oxo-1,4-dihydrobenzo[h] quinoline-3-carboxylic acid (9) (IC50 = 1 AM), are ATP competitive (K-i values are 0.06 and 0.28 mu M, respectively). Evaluation of the inhibitors on seven protein kinases shows considerable selectivity toward CK2. According to theoretical calculations and experimental data, a structural model describing the key features of 3-carboxy-4(1H)-quinolones responsible for tight binding to CK2 active site has been developed.
