Abstract The Stimulator of Interferon Genes (STING) plays an important role in innate immunity by inducing type I interferons response to sensing viral or bacterial cytosolic DNA. Cyclic dinucleotides (CDNs) are known activate STING. Here, we describe the synthesis and biological evaluation two new 3’,3’‐CDN, which internucleotide linkages were replaced, respectively, a 1,2,3‐triazole moiety (a...
