  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
