  Ten benzoxazole clubbed 2-pyrrolidinones (11–20) as human monoacylglycerol lipase inhibitors were designed on the criteria fulfilling the structural requirements and on the basis of previously reported inhibitors. The designed, synthesized, and characterized compounds (11–20) were screened against monoacylglycerol lipase (MAGL) in order to find potential inhibitors. Compounds 19 (4-NO2 derivative) and 20 (4-SO2NH2 derivative), with an IC50 value of 8.4 and 7.6 nM, were found most active, respectively. Both of them showed micromolar potency (IC50 value above 50 µM) against a close analogue, fatty acid amide hydrolase (FAAH), therefore considered as selective inhibitors of MAGL. Molecular docking studies of compounds 19 and 20 revealed that carbonyl of 2-pyrrolidinone moiety sited at the oxyanion hole of catalytic site of the enzyme stabilized with three hydrogen bonds (~2 Å) with Ala51, Met123, and Ser122, the amino acid residues responsible for the catalytic function of the enzyme. Remarkably, the physiochemical and pharmacokinetic properties of compounds 19 and 20, computed by QikProp, were found to be in the qualifying range as per the proposed guideline for good orally bioactive CNS drugs. In formalin-induced nociception test, compound 20 reduced the pain response in acute and late stages in a dose-dependent manner. They significantly demonstrated the reduction in pain response, having better potency than the positive control gabapentin (GBP), at 30 mg/kg dose. Compounds 19 and 20 were submitted to NCI, USA, for anticancer activity screening. Compounds 19 (NSC: 778839) and 20 (NSC: 778842) were found to have good anticancer activity on SNB-75 cell line of CNS cancer, exhibiting 35.49 and 31.88% growth inhibition (% GI), respectively.

  设计了十种苯并噁唑与2-吡咯酮结合的人类单酰甘油酶抑制剂（11-20），根据先前报道的抑制剂的结构要求和基础设计。设计、合成和表征的化合物（11-20）针对单酰甘油酶（MAGL）进行筛选，以寻找潜在的抑制剂。化合物19（4-NO2衍生物）和20（4-SO2NH2衍生物）的IC50值分别为8.4和7.6 nM，是最活跃的。它们对于一个相似的分子，脂肪酸酰胺水解酶（FAAH），显示出微摩尔级别的活性（IC50值大于50µM），因此被认为是MAGL的选择性抑制剂。化合物19和20的分子对接研究表明，2-吡咯酮结构中的酰基位于酶的催化位点的氧酰离子孔中，与负责酶催化功能的氨基酸残基Ala51、Met123和Ser122形成三个氢键（约2埃）。值得注意的是，通过QikProp计算，化合物19和20的理化和药代性质符合良好口服生物活性中枢神经系统药物的建议指南。在甲醛诱导的疼痛实验中，化合物20以剂量依赖方式减少了急性和迟发性阶段的疼痛反应。它们显著地减少了疼痛反应，比阳性对照加巴喷丁（GBP）在30毫克/千克剂量下具有更好的效力。化合物19和20被提交给美国国家癌症研究所（NCI）进行抗癌活性筛选。化合物19（NSC：778839）和20（NSC：778842）在中枢神经系统癌症SNB-75细胞系上表现出良好的抗癌活性，分别显示出35.49%和31.88%的生长抑制率（%GI）。

Herein, we describe the discovery of inhibitors targeting the active site cysteine of the catalytic subunit HOIP using fragment-based covalent ligand screening.

  用多聚泛素链修饰蛋白质是控制细胞行为的关键调节机制，泛素系统的改变与许多疾病有关。线性（M1 连接）多聚泛素链在介导免疫和炎症反应以及细胞凋亡的多种细胞信号通路中发挥关键作用。这些链由线性泛素链组装复合物 (LUBAC) 形成，LUBAC 是一种多蛋白 E3 连接酶，由 3 个亚基 HOIP、HOIL-1L 和 SHARPIN 组成。在此，我们描述了使用基于片段的共价配体筛选靶向催化亚基 HOIP 的活性位点半胱氨酸的抑制剂的发现。我们报告了多种亲电片段库的合成，并展示了蛋白质 LC-MS、生化泛素化分析、化学合成、和蛋白质晶体学，使 RBR E3 连接酶的共价抑制剂的第一个基于结构的开发成为可能。此外，使用基于细胞的测定和化学蛋白质组学，我们证明这些化合物有效地渗透哺乳动物细胞以标记和抑制 HOIP 和 NF-κB 激活，使其成为开发选择性探针以研究 LUBAC 生物学的合适选择。我们的
