  STING (Stimulator of Interferon Genes) has become a focal point in immunology research and a target in drug discovery. The discovery of a potent human-STING agonist is expected to revolutionize current anti-virus or cancer immunotherapy. Inspired by the structure and function of murine STING-specific agonists (DMXAA and CMA), we rationally designed and synthesized four series of novel compounds for

  STING（干扰素基因的刺激物）已成为免疫学研究的重点和药物发现的目标。有望发现有效的人类STING激动剂，将彻底改变当前的抗病毒或癌症免疫疗法。受鼠STING特异性激动剂（DMXAA和CMA）的结构和功能的启发，我们合理设计和合成了四组新化合物以增强人类敏感性。在基于细胞的分析中，我们从所有合成的小分子中鉴定出六种化合物：2g，9g和12b是STING激动剂，在整个物种中均有效，并且都具有a啶酮的骨架。1b，1c和12c仅在鼠STING途径中起作用。值得注意的是，12b在六种激动剂中表现出最好的活性，其对人和鼠STING依赖性信号转导的诱导作用均与众所周知的STING诱导剂2'3'-cGAMP相似。蛋白质分析表明2 g，9 g和12b可通过直接结合人STING激活该途径，而12b也显示出最强的结合亲和力。此外，我们的研究表明，与2'3'-cGAMP相比，在天然系统中12b可以诱导更快，更

  The enantioselective synthesis of isochroman motifs has been accomplished by palladium(II)‐catalyzed allylic C−H oxidation from terminal olefin precursors. Critical to the success of this goal was the development and utilization of a novel chiral aryl sulfoxide‐oxazoline (ArSOX) ligand. The allylic C−H oxidation reaction proceeds with the broadest scope and highest levels of asymmetric induction reported

  has been closely linked to cancer. Selective inhibitors of this enzyme are lacking. Inspired by DNA lesions produced by antitumor agents that inactivate Pol β, we have undertaken the development of covalent small-molecule inhibitors of this enzyme. Using a two-stage process involving chemically synthesized libraries, we identified a potent irreversible inhibitor (14) of Pol β (KI = 1.8 ± 0.45 μM, kinact

  DNA 聚合酶 β (Pol β) 在 DNA 修复中起着至关重要的作用，并且与癌症密切相关。缺乏这种酶的选择性抑制剂。受使 Pol β 失活的抗肿瘤剂产生的 DNA 损伤的启发，我们着手开发这种酶的共价小分子抑制剂。使用涉及化学合成文库的两阶段过程，我们确定了Pol β的有效不可逆抑制剂 ( 14 ) ( K I = 1.8 ± 0.45 μM, k inact = (7.0 ± 1.0) × 10 –3 s –1 )。抑制剂14比其他 DNA 聚合酶选择性地灭活 Pol β。用14处理的 Pol β 胰蛋白酶消化物的 LC-MS/MS 分析鉴定了聚合酶结合位点内共价修饰的两个赖氨酸，其中一个先前被确定在DNA结合中起作用。荧光各向异性实验表明，用14预处理 Pol β可防止 DNA 结合。在野生型小鼠胚胎成纤维细胞 (MEF) 中使用前抑制剂 ( pro - 14 ) 的实验表明，抑制剂
