  Synthesis of New Glucose-containing 5-Arylisoxazoles and their Enzyme Inhibitory Activity

  摘要：

  Abstract: Carbohydrates are an important group of biomolecules that have received special attention due to their significant role in the design and synthesis of new bioactive compounds. In this study, a new class of 5-arylisoxazole-glucose hybrids was designed and synthesized for evaluation of their inhibitory effects on α-glucosidase, α-amylase, and tyrosinase. The target compounds depicted selective α-glucosidase inhibitory activity over α-amylase, which is an important factor in reducing probable gastrointestinal problems in the treatment of type 2 diabetes. In this respect, compound 9a, possessing the phenylisoxazole group, was found to be the most potent α-glucosidase inhibitor (IC50 = 292.2 ± 0.1 μM) compared to acarbose (IC50 = 750.2 ± 0.1 μM) as the positive control. All compounds were also evaluated for their anti-tyrosinase effect, and among them, compound 9j, containing a fluoroaryl moiety, showed potent activity (IC50 = 50.1 ± 6.3 μM) in comparison to kojic acid (IC50 = 23.6 ± 2.6 μM). Also, docking studies were performed to investigate the probable mode of action, which indicated the construction of important H-bonding interactions between the sugar moiety and the enzyme’s active sites. According to the results, hybrids containing heterocycles attached to glucose can be used to inhibit α-glucosidase.

  N-联苯吡咯啉酮和二苯并呋喃作为 RNA 结合蛋白 LIN28 抑制剂，破坏 LIN28–Let-7 相互作用

  摘要：

  RNA 结合蛋白 LIN28 是 miRNA let-7生物发生的调节因子。鉴于 LIN28 在肿瘤发生和癌症干细胞发育中发挥的核心作用以及 LIN28 与不良临床预后的相关性，LIN28 抑制剂受到高度追捧。尽管已经报道了不同支架的 LIN28 抑制剂，但由于进行的构效关系 (SAR) 研究非常有限，因此大多数 LIN28 抑制小分子的潜力尚未得到充分探索。我们之前将三取代吡咯啉酮确定为一类新的 LIN28 抑制剂，可破坏 LIN28- let-7相互作用。在这里，我们通过评估 95 个小分子进行了广泛的 SAR，并鉴定了具有N-联苯或N-二苯并呋喃取代基的新型三取代吡咯啉酮，推翻了水杨酸部分对于活性必不可少的现有结论。用杂环取代基交换 LIN28 抑制剂中带负电荷的水杨酸部分有利于膜通透性，导致细胞测定中的活性增加，并有可能降低毒性。

  FXIa is suggested as a major target for anticoagulant drug discovery because of reduced risk of bleeding. In this paper, we defined 5-phenyl-1H-pyrazole-3-carboxylic acid derivatives as privileged fragments for FXIa inhibitors’ lead discovery. After replacing the (E)-3-(5-chloro-2-(1H-tetrazol-1-yl)phenyl)acrylamide moiety in compound 3 with 5-(3-chlorophenyl)-1H-pyrazole-3-carboxamide, we traveled from FXIa inhibitor3 to a scaffold that fused the privileged fragments into a pharmacophore for FXIa inhibitors. Subsequently, we synthesized and assessed the FXIa inhibitory potency of a series of 5-phenyl-1H-pyrazole-3-carboxamide derivatives with different P1, P1′ and P2′moiety. Finally, the SAR of them was systematically investigated to afford the lead compound 7za (FXIa Ki = 90.37 nM, 1.5× aPTT in rabbit plasma = 43.33μM) which exhibited good in vitro inhibitory potency against FXIa and excellent in vitro coagulation activities. Furthermore, the binding mode of 7za with FXIa was studied and the results suggest that the 2-methylcyclopropanecarboxamide group of 7za makes 2 direct hydrogen bonds with Tyr58B and Thr35 in the FXIa backbone, making 7za binds to FXIa in a highly efficient manner.

  FXIa被认为是抗凝药物发现的主要靶点，因为减少了出血风险。在这篇论文中，我们将5-苯基-1H-吡唑-3-羧酸衍生物定义为FXIa抑制剂的引物片段，用于引物发现。在将化合物3中的(E)-3-(5-氯-2-(1H-四唑-1-基)苯基)丙烯酰胺基团替换为5-(3-氯苯基)-1H-吡唑-3-羧酰胺后，我们从FXIa抑制剂3转变为将引物片段融合成FXIa抑制剂的药效团的支架。随后，我们合成并评估了一系列具有不同P1、P1'和P2'基团的5-苯基-1H-吡唑-3-羧酰胺衍生物的FXIa抑制活性。最后，对它们的结构活性关系进行了系统研究，得到了引物化合物7za（FXIa Ki = 90.37 nM，在兔血浆中1.5× aPTT = 43.33μM），该化合物表现出良好的体外抑制FXIa活性和优秀的体外凝血活性。此外，研究了7za与FXIa的结合方式，结果表明7za的2-甲基环丙烷甲酰胺基团与FXIa骨架中的Tyr58B和Thr35直接形成两个氢键，使7za以高效的方式结合到FXIa上。
