  Structure–activity relationship of human glutaminyl cyclase inhibitors having an N-(5-methyl-1H-imidazol-1-yl)propyl thiourea template

  摘要：

  In an effort to design inhibitors of human glutaminyl cyclase (QC), we have synthesized a library of N-aryl N-(5-methyl-1H-imidazol-1-yl)propyl thioureas and investigated the contribution of the aryl region of these compounds to their structure-activity relationships as cyclase inhibitors. Our design was guided by the proposed binding mode of the preferred substrate for the cyclase. In this series, compound 52 was identified as the most potent QC inhibitor with an IC50 value of 58 nM, which was two-fold more potent than the previously reported lead 2. Compound 52 is a most promising candidate for future evaluation to monitor its ability to reduce the formation of pGlu-A beta and A beta plaques in cells and transgenic animals.

  recruiter, have arisen as a powerful therapeutic modality for targeted protein degradation (TPD). Despite the popularity of TPD approaches in drug discovery, only a small number of E3 ligase recruiters are available for the >600 E3 ligases that exist in human cells. Here, we have discovered a cysteine-reactive covalent ligand, EN106, that targets FEM1B, an E3 ligase recently discovered as the critical component

  蛋白水解靶向嵌合体 (PROTAC) 是一种异双功能化合物，由与 E3 连接酶募集剂连接的蛋白靶向配体组成，已成为靶向蛋白降解 (TPD) 的强大治疗方式。尽管 TPD 方法在药物发现中很受欢迎，但只有少数 E3 连接酶招募人员可用于人类细胞中存在的 >600 E3 连接酶。在这里，我们发现了一种半胱氨酸反应性共价配体 EN106，其靶向 FEM1B，这是一种最近发现的 E3 连接酶，是细胞对还原应激反应的关键组成部分。通过针对 FEM1B 中的 C186，EN106 破坏了对 FEM1B 关键还原应力基质 FNIP1 的识别。我们通过证明将 EN106 连接到 BET 溴结构域抑制剂 JQ1 或激酶抑制剂达沙替尼的 PROTAC 分别导致 BRD4 和 BCR-ABL 的降解，进一步确定 EN106 可用作 TPD 应用中 FEM1B 的共价招募剂。我们的研究展示了一种针对天然 E3 连
