  The monoethyl ester of meconic acid is an active site inhibitor of HCV NS5B RNA-dependent RNA polymerase

  摘要：

  Screening of the in-house sample collection for compounds with HCV NS5B RNA dependent RNA polymerase inhibition led to the identification of a new lead. Afterwards, we discovered that the screening lead, rather than containing the expected structure 1, was comprised of roughly a 1:1 mixture of meconic acid 2 and its monoethyl ester 3, with all inhibitory potency residing with 3. We propose that this compound shares critical common features for activity with alpha,gamma-diketoacids inhibitors previously discovered by our group. SAR around this molecule will be presented to provide an improved basis for structure-based ligand design. (C) 2004 Elsevier Ltd. All rights reserved.

  modulators. Herein, a novel Ras inhibitor (compound 12) is described that selectively impairs mutated Ras activity in a reversible manner without significantly affecting wild‐type Ras, reduces the Ras–guanosine triphosphate (GTP) levels, inhibits the activation of the mitogen‐activated protein kinase (MAPK) pathway, and exhibits remarkable cytotoxic activity in Ras‐driven cellular models. The use of molecular

  尽管经过三十多年的艰苦努力，仍没有抗Ras疗法达到临床应用。导致这种失败的原因是人们低估了Ras的复杂性和缺乏结构信息。在这方面，最近的研究揭示了Ras表面的高度动态特性以及适合于小分子结合的瞬时口袋的存在，为Ras调节剂的开发开辟了新的可能性。本文中，一种新型的Ras抑制剂（化合物12）被描述为以可逆的方式选择性破坏突变的Ras活性而不会显着影响野生型Ras，降低Ras-鸟苷三磷酸（GTP）水平，抑制促分裂原活化的蛋白激酶（MAPK）途径的激活并表现出显着性在Ras驱动的细胞模型中具有细胞毒活性。分子动力学模拟和NMR光谱实验的使用使得能够探索负责化合物12与Ras蛋白之间相互作用的分子碱基。新的Ras抑制剂与GTP结合区域部分结合，并延伸到由开关II界定的相邻疏水口袋中。因此，Ras抑制剂12可能代表开发针对Ras致癌的更有效药物的新化合物；当前未满足的临床需求。

  A series of kojic acid (5-hydroxy-2-hydroxymethyl-4H-pyran-4-one) derivatives were synthesized and tested for their ability to inhibit D-amino acid oxidase (DAAO). Various substituents were incorporated into kojic acid at its 2-hydroxymethyl group. These analogs serve as useful molecular probes to explore the secondary binding site, which can be exploited in designing more potent DAAO inhibitors. (c) 2013 Elsevier Ltd. All rights reserved.
