  2-Aminonicotinic Acid 1-Oxides Are Chemically Stable Inhibitors of Quinolinic Acid Synthesis in the Mammalian Brain: A Step toward New Antiexcitotoxic Agents

  摘要：

  3-Hydroxyanthranilic acid 3,4-dioxygenase (3-HAO) is the enzyme responsible for the production of the neurotoxic tryptophan metabolite quinolinic acid (QUIN). Elevated brain levels of QUIN are observed in several neurodegenerative diseases, but pharmacological investigation on its role in the pathogenesis of these conditions is difficult because only one class of substrate-analogue 3-HAO inhibitors, with poor chemical stability, has been reported so far. Here we describe the design, synthesis, and biological evaluation of a novel class of chemically stable inhibitors based on the 2-aminonicotinic acid 1-oxide nucleus. After the preliminary in vitro evaluation of newly synthesized compounds using brain tissue homogenate, we selected the most active inhibitor and showed its ability to acutely reduce the production of QUIN in the rat brain in vivo. These findings provide a novel pharmacological tool for the study of the mechanisms underlying the onset and propagation of neurodegenerative diseases.

  Discovery of Novel Dual Extracellular Regulated Protein Kinases (ERK) and Phosphoinositide 3-Kinase (PI3K) Inhibitors as a Promising Strategy for Cancer Therapy

  摘要：

  MAPK和PI3K信号通路的同时抑制已被认为是癌症治疗的一种有前途的策略，可以有效地克服MAPK信号通路相关抑制剂的药物抗性。在这里，我们报告了一系列1H-吡唑[3,4-d]嘧啶双ERK/PI3K抑制剂的骨架跳跃生成。化合物32d是最有前途的候选药物，对ERK2和PI3Kα均具有强大的抑制活性，对HCT116和HEC1B癌细胞显示出优越的抗增殖特性。与此同时，化合物32d具有可接受的药代动力学特性，并且在HCT-116移植瘤模型中显示出比GDDC-0980和相应的药物组合（BVD-523 + GDDC-0980）更有效的抗肿瘤活性，肿瘤生长抑制率为51%，且没有造成明显的毒性效应。所有结果表明，32d是一种高效的抗癌化合物，并为进一步优化向双ERK/PI3K抑制剂提供了有前途的基础。
