  (NFκB) signaling cascades. In this work, we describe an enzymatic preparation of 2′–5′,3′–5′-cyclic dinucleotides (2′3′CDNs) with use of cyclic GMP–AMP synthases (cGAS) from human, mouse, and chicken. We profile substrate specificity of these enzymes by employing a small library of nucleotide-5′-triphosphate (NTP) analogues and use them to prepare 33 2′3′CDNs. We also determine affinity of these CDNs to

  环状二核苷酸是环状GMP-AMP合酶（cGAS）-干扰素基因刺激（STING）途径的第二信使，在识别肿瘤细胞和病毒或细菌感染中起着重要作用。它们与STING衔接蛋白结合并通过TANK结合激酶1（TBK1）/干扰素调节因子3（IRF3）和核因子-κB（IκB）激酶（IKK）/核因子-κB（NFκB）抑制剂触发细胞因子的表达信号级联。在这项工作中，我们描述了使用人，小鼠和鸡的环状GMP-AMP合成酶（cGAS）酶法制备2'-5'，3'-5'-环二核苷酸（2'3'CDNs）的方法。我们通过使用一个小的核苷酸5'-三磷酸（NTP）类似物文库来分析这些酶的底物特异性，并使用它们来制备33个2'3'CDN。我们还确定了这些CDN对基于细胞和生化分析的五种不同STING单倍型的亲和力，并描述了它们对所有STING单倍型的最佳活性所需的特性。接下来，我们研究它们对人外周血单核细胞（PBMC）诱导的细胞因子
