制备方法与用途

用途

3-硝基水杨酸甲酯可作为农药、医药、染料、化纤、橡胶和含能材料等产品的中间体。

制备

传统的合成方法是将水杨酸甲酯直接用硝酸和硫酸的混酸进行硝化，但主要以5-位硝化为主，3-硝基水杨酸甲酯的产率约为10%左右。此外，它还可用于制备药物中间体。

  用于治疗自身免疫性疾病的酪氨酸激酶 2 (TYK2) 的高度选择性抑制：变构抑制剂 BMS-986165 的发现。

  摘要：

  小分子 JAK 抑制剂已成为治疗自身免疫性疾病的重大治疗进展。发现传统上靶向该激酶家族催化活性位点的同种型选择性 JAK 抑制剂一直是一项艰巨的挑战。我们实现 TYK2 高选择性的策略依赖于靶向 TYK2 假激酶 (JH2) 域。在此，我们报告了后期优化工作，包括结构引导设计和水置换策略，这些工作导致发现 BMS-986165 ( 11 ) 作为高亲和力 JH2 配体和 TYK2 的有效变构抑制剂。除了前所未有的 JAK 异构体和激酶组选择性，11显示出优异的药代动力学特性，具有最小的分析能力，并且在多种自身免疫性疾病的小鼠模型中有效。基于这些发现，11似乎与所有其他报道的 JAK 抑制剂不同，并且已作为临床开发中第一个假激酶导向的治疗剂作为自身免疫性疾病的口服治疗而被推进。

  金属结合药效团点击衍生的新型广谱金属-β-内酰胺酶抑制剂的发现

  摘要：

  金属-β-内酰胺酶（MBL）的出现赋予了对几乎所有β-内酰胺抗生素（包括碳青霉烯类）的耐药性。目前，缺乏临床上有用的 MBL 抑制剂，因此发现能够有效靶向多种临床相关 MBL 的新抑制剂化学型至关重要。在此，我们报告了一种利用金属结合药效团 (MBP) 点击方法来识别新的广谱 MBL 抑制剂的策略。我们的初步研究确定了几种 MBP，包括邻苯二甲酸、苯基硼酸和苄基磷酸，它们使用叠氮-炔点击反应进行结构转变。随后的结构-活性关系分析导致了几种有效的广谱 MBL 抑制剂的鉴定，包括针对多种 MBL 的 IC 值范围为 0.00012 μM 至 0.64 μM。共晶研究证明了 MBP 在与 MBL 活性位点锚定药效团特征结合方面的重要性，并揭示了与 IMP-1 不寻常的两分子结合模式，强调了灵活的活性位点环在识别结构多样的底物/抑制剂中的关键作用。我们的工作为 MBL 抑制提供了新的化学型，并为针对
