  Design and Evaluation of Hydroxamate Derivatives as Metal-Mediated Inhibitors of a Protein Tyrosine Kinase

  摘要：

  Protein tyrosine kinases use two Mg2+ ions as cofactors in catalysis, one as the ATP-Mg complex (M1) and the other as an essential activator (M2). The M2-binding site has high affinity for transition metal cations such as cobalt and zinc. Taking advantage of this high affinity, we examined hydroxamates as metal-mediated inhibitors against C-terminal Src kinase (Csk), a protein tyrosine kinase. Of a small group of amino acid hydroxamates, tyrosine and phenylalanine hydroxamates inhibited Csk activity only in the presence of Co2+. Four classes of phenylalanine and tyrosine hydroxamate derivatives were synthesized and evaluated as metal-mediated inhibitors of Csk, leading to improved inhibition and a better understanding of the structure-activity relationships. This study suggests that hydroxamates may serve as a general scaffold for developing metal-mediated inhibitors against protein tyrosine kinases. To the best of our knowledge, this is the first report of designing metal-mediated inhibitors against a protein tyrosine kinase by targeting a metal binding site.

  that can identify full ligand structures from large‐scale DEDLs. This method is also able to convert unbiased libraries into focused ones targeting specific protein classes. We demonstrated this method by selecting DEDLs against five proteins, and novel inhibitors were identified for all targets. Notably, several selective BD1/BD2 inhibitors were identified from the selections against bromodomain 4 (BRD4)

  动态组合库（DCL）是生物医学研究中配体发现的强大工具。但是，DCL的低多样性阻碍了它们的应用。最近，DCL中已经采用了DNA编码的概念来创建DNA编码的动态库（DEDL）。但是，当前所有的DEDL都仅限于片段识别，并且在选择后需要一个具有挑战性的片段链接过程。我们报告了一种锚定的DEDL方法，该方法可以从大规模DEDL中识别出完整的配体结构。这种方法还能够将无偏文库转换为针对特定蛋白质类别的集中文库。我们通过选择针对五种蛋白质的DEDLs证明了这种方法，并为所有靶标确定了新型抑制剂。值得注意的是 从针对重要的抗癌药物靶标bromodomain 4（BRD4）的选择中鉴定出了几种选择性的BD1 / BD2抑制剂。这项工作可以为抑制剂发现提供广泛适用的方法。

  Inhibition of KEAP1-NRF2 protein-protein interaction is considered a promising strategy to selectively and effectively activate NRF2, a transcription factor which is involved in several pathologies such as Huntington’s disease (HD). A library of linear peptides based on the NRF2-binding motifs was generated on the nonapeptide lead Ac-LDEETGEFL-NH2 spanning residues 76–84 of the Neh2 domain of NRF2

  抑制KEAP1-NRF2蛋白质-蛋白质相互作用被认为是有选择地和有效地激活NRF2的一种有前途的策略，NRF2是一种转录因子，涉及多种病理学，例如亨廷顿舞蹈病（HD）。在非肽铅Ac-LDEETGEFL-NH 2上生成了基于NRF2结合基序的线性肽库跨越NRF2 Neh2域的76-84位残基，目的是用非酸性氨基酸取代E78，E79和E82。基于结构的设计还旨在更深入地了解T80副口袋的功能和可及性。研究了使用不同种类的环肽以及与细胞穿透肽结合的提高细胞通透性的方法。这一见识将指导大环化合物，肽模拟物以及最重要的是中性小脑穿透分子的未来设计，以评估NRF2激活剂是否可用于HD。

  As tool compounds to study cardiac ischemia, the endogenous δ-opioid receptors (δOR) agonist Leu5-enkephalin and the more metabolically stable synthetic peptide (d-Ala2, d-Leu5)-enkephalin are frequently employed. However, both peptides have similar pharmacological profiles that restrict detailed investigation of the cellular mechanism of the δOR’s protective role during ischemic events. Thus, a need remains for δOR peptides with improved selectivity and unique signaling properties for investigating the specific roles for δOR signaling in cardiac ischemia. To this end, we explored substitution at the Phe4 position of Leu5-enkephalin for its ability to modulate receptor function and selectivity. Peptides were assessed for their affinity to bind to δORs and µ-opioid receptors (µORs) and potency to inhibit cAMP signaling and to recruit β-arrestin 2. Additionally, peptide stability was measured in rat plasma. Substitution of the meta-position of Phe4 of Leu5-enkephalin provided high-affinity ligands with varying levels of selectivity and bias at both the δOR and µOR and improved peptide stability, while substitution with picoline derivatives produced lower-affinity ligands with G protein biases at both receptors. Overall, these favorable substitutions at the meta-position of Phe4 may be combined with other modifications to Leu5-enkephalin to deliver improved agonists with finely tuned potency, selectivity, bias and drug-like properties.

  作为研究心脏缺血的工具化合物，内源性δ-阿片受体（δOR）激动剂Leu5-恩啡啶和更具代谢稳定性的合成肽（d-Ala2，d-Leu5）-恩啡啶经常被使用。然而，这两种肽具有类似的药理特性，限制了对δOR在缺血事件中保护作用的细胞机制进行详细研究。因此，需要具有改进选择性和独特信号特性的δOR肽，以便研究心脏缺血中δOR信号的特定作用。为此，我们探索了Leu5-恩啡啶的Phe4位置的取代物对调节受体功能和选择性的能力。评估了肽对δOR和µ-阿片受体（µOR）的结合亲和力以及抑制cAMP信号和招募β-阻滞蛋白2的效力。此外，还测量了肽在大鼠血浆中的稳定性。通过在Leu5-恩啡啶的Phe4的间位进行取代，提供了具有不同选择性和偏向性水平的高亲和力配体，同时改善了肽的稳定性，而用吡啶衍生物进行取代则产生了在两种受体上具有G蛋白偏向性的亲和力较低的配体。总的来说，Phe4的间位的这些有利取代物可以与Leu5-恩啡啶的其他修饰结合，提供具有精心调节的效力、选择性、偏向性和药物样性质的改进激动剂。
