We describe novel STING-activating cyclic dinucleotides whose constituent nucleosides are adenosine and inosine and that vary by ribose substitution, internucleotide linkage position, and phosphate modification. In mammalian cells in vitro, some of these cAIMP analogs induce greater STING-dependent IRF and NF-κB pathway signaling than do the reference agonists for murine (DMXAA) or human (2′,3′-cGAMP)
我们描述了新型STING激活环状二核苷酸,其组成核苷为腺苷和肌苷,并通过核糖取代,核苷酸间键合位置和磷酸修饰而变化。在体外哺乳动物细胞中,这些cAIMP类似物中的一些诱导的STING依赖性IRF和NF-κB途径信号传导比鼠类(DMXAA)或人(2',3'-cGAMP)STING的参考激动剂要强。在人血液中体外,它们诱导I型干扰素(IFN)和促炎细胞因子:对于前者,3',3'-cAIMP(9 ; EC 50 6.4μM)和类似物52 - 56(EC 50含有一个或两个2'-氟-2'-脱氧核糖和/或双硫代磷酸酯键的分子,其浓度为0.4-4.7μM)比2',3'-cGAMP(EC 50为19.6μM)更有效。有趣的是,9比其连接异构体2',3'-cAIMP(10),3',2'-cAIMP(23)和2',2'-cAIMP(27)诱导I型IFN的作用更强。最后,一些cAIMP类似物比2',3'-cG
