  Synthesis and Antitumor Activity of New Derivatives of Xanthen-9-one-4-acetic Acid

  摘要：

  Xanthen-9-one-4-acetic acid (XAA) analogues in which the substituents in positions 5 and 6 are included in cyclic structures are described. Direct in vitro toxicity of the synthesized compounds against four tumor cell lines was evaluated, and their ability to stimulate mouse peritoneal macrophages and human monocytes in culture to become tumoricidal (indirect toxicity) was also studied. Despite low direct toxicity, almost all,the compounds proved to be able to significantly enhance the lytic properties of both murine macrophages and human monocytes. as well as the parent compound XAA and its most active derivative DMXAA taken as reference. In particular, compounds 4a, 5a, 7a, 13a,b, and 16a,b showed higher activity than the lead compound on human monocytes, compound 7a being 2.5 times more active than DMXAA, which is the most potent compound synthesized so far. Moreover, compounds 4a, 5a, 7a, 13a, 16a, and 16b proved to be able to induce TNF production in human immune cells.

  Potential antitumor agents. 58. Synthesis and structure-activity relationships of substituted xanthenone-4-acetic acids active against the colon 38 tumor in vivo

  摘要：

  In a search for compounds related to flavoneacetic acid with activity against solid tumors, a series of methyl-, methoxy-, chloro-, nitro-, and hydroxy-substituted xanthenone-4-acetic acids have been synthesized and evaluated against subcutaneously implanted colon adenocarcinoma 38 in vivo, using a short-term histology assay as a primary screening system. A major goal of this work was to identify compounds with similar profiles of activity to that of flavoneacetic acid but of higher potency. The level of activity of the compounds appeared to depend more on the nature of the substituent than its positioning, in the order Cl greater than Me, OMe greater than NO2, OH. However, the potency of the compounds was related much more to the position rather than the nature of the substitution, with 5-substituted compounds being clearly the most dose potent. 5-Methylxanthenone-4-acetic acid has a similar level of activity to that of flavoneacetic acid in the test systems employed but is more than 7-fold as dose potent.

  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
