  Inhibition of Lymphoid Tyrosine Phosphatase by Benzofuran Salicylic Acids

  摘要：

  The lymphoid tyrosine phosphatase (Lyp, PTPN22) is a critical negative regulator of T cell antigen receptor (TCR) signaling. A single-nucleotide polymorphism (SNP) in the ptpn22 gene correlates with the incidence of various autoimmune diseases, including type I diabetes, rheumatoid arthritis, and systemic lupus erythematosus. Since the disease-associated allele is a more potent inhibitor of TCR signaling, specific Lyp inhibitors May become valuable in treating autoimmunity. Using a structure-based approach, we synthesized a library of 34 compounds that inhibited Lyp with IC50 values between 0.27 and 6.2 mu M. A reporter assay was employed to screen for compounds that enhanced TCR signaling in cells, and several inhibitors displayed a dose-dependent, activating effect. Subsequent probing for Lyp's direct physiological targets by immunoblot analysis confirmed the ability of the compounds to inhibit Lyp in T cells. Selectivity profiling against closely related tyrosine phosphatases and in silico docking studies with the crystal structure of Lyp yielded valuable information for the design of Lyp-specific compounds.

  homology-2 domain containing protein tyrosine phosphatase-2 (SHP2) plays a pivotal role in growth factor and cytokine signaling. Gain-of-function SHP2 mutations are associated with Noonan syndrome, various kinds of leukemias, and solid tumors. Thus, there is considerable interest in SHP2 as a potential target for anticancer and antileukemia therapy. We report a salicylic acid based combinatorial library approach

  Src homology-2 域包含蛋白酪氨酸磷酸酶-2 (SHP2) 在生长因子和细胞因子信号传导中起关键作用。功能获得性 SHP2 突变与 Noonan 综合征、各种白血病和实体瘤有关。因此，人们对 SHP2 作为抗癌和抗白血病治疗的潜在靶点有相当大的兴趣。我们报告了一种基于水杨酸的组合文库方法，旨在结合活性位点和附近独特的亚袋，以提高亲和力和选择性。文库的筛选导致鉴定出具有高效细胞活性的 SHP2 抑制剂 II-B08（化合物9）。化合物9阻断生长因子刺激的 ERK1/2 激活和造血祖细胞增殖，提供支持证据表明 SHP2 的化学抑制可能对抗癌和抗白血病治疗有治疗作用。与9复合的 SHP2 结构的 X 射线晶体学分析揭示了可用于获得更有效和选择性 SHP2 抑制剂的分子决定因素。

  We uncovered that mPTPB subverts the innate immune responses by blocking the ERK1/2 and p38 mediated IL-6 production and promoting host cell survival by activating the Akt pathway. We identified a potent and selective mPTPB inhibitor I-A09 with highly efficacious cellular activity, from a combinatorial library of bidentate benzofuran salicylic acid derivatives assembled by click chemistry. We demonstrated

  蛋白质酪氨酸磷酸酶常被病原菌利用和破坏，引起人类疾病。来自结核分枝杆菌的酪氨酸磷酸酶 mPTPB 是一种必需的毒力因子，由细菌分泌到巨噬细胞的细胞质中，在那里它介导分枝杆菌在宿主中的存活。因此，人们对了解 mPTPB 逃避宿主免疫反应的机制以及开发作为独特抗结核 (antiTB) 药物的强效和选择性 mPTPB 抑制剂具有相当大的兴趣。我们发现 mPTPB 通过阻断 ERK1/2 和 p38 介导的 IL-6 产生并通过激活 Akt 通路促进宿主细胞存活来破坏先天免疫反应。我们鉴定了一种具有高效细胞活性的强效选择性 mPTPB 抑制剂 I-A09，来自通过点击化学组装的双齿苯并呋喃水杨酸衍生物的组合文库。我们证明了在巨噬细胞中用 I-A09 抑制 mPTPB 可以逆转细菌磷酸酶诱导的宿主免疫反应的改变，并防止宿主细胞中的结核病生长。结果提供了必要的原理验证数据，以支持 mPTPB 的特定抑制剂可作为有效的抗结核治疗剂的观点。
• Derivatives of Salicylic Acid as Inhibitors of YopH in Yersinia pestis

  Yersinia pestis causes diseases ranging from gastrointestinal syndromes to bubonic plague and could be misused as a biological weapon. As its protein tyrosine phosphatase YopH has already been demonstrated as a potential drug target, we have developed two series of forty salicylic acid derivatives and found sixteen to have micromolar inhibitory activity. We designed these ligands to have two chemical moieties connected by a flexible hydrocarbon linker to target two pockets in the active site of the protein to achieve binding affinity and selectivity. One moiety possessed the salicylic acid core intending to target the phosphotyrosine‐binding pocket. The other moiety contained different chemical fragments meant to target a nearby secondary pocket. The two series of compounds differed by having hydrocarbon linkers with different lengths. Before experimental co‐crystal structures are available, we have performed molecular docking to predict how these compounds might bind to the protein and to generate structural models for performing binding affinity calculation to aid future optimization of these series of compounds.

  鼠疫杆菌 可引起从胃肠综合征到腺鼠疫等多种疾病，并可能被滥用为生物武器。由于其蛋白酪氨酸磷酸酶 YopH 已被证明是一个潜在的药物靶点，我们研发了两个系列总共 40 种水杨酸衍生物，并发现其中有 16 种具有微摩尔抑制活性。我们设计这些配体，使其通过一个灵活的烃类连接链连接两种不同的化学基团，以作用于蛋白活性位点的两个口袋，从而实现对结合亲和力和选择性的控制。其中一个基团以水杨酸为核心，旨在针对磷酸酪氨酸结合口袋；另一个基团则包含不同的化学片段，用于靶向邻近的次要口袋。这两个系列的化合物区别于它们的烃类连接链长度不同。在实验共晶结构可获得之前，我们进行了分子对接，以预测这些化合物如何与蛋白结合，并建立结构模型，计算结合亲和力，以辅助未来对这一系列化合物的优化工作。
