Common Name2',3'-cGAMP
Description2',3'-cGAMP is a cyclic dinucleotide belonging to the class of nucleotide metabolites. Its chemical structure consists of a guanosine and an adenosine moiety linked by a phosphate group, forming a cyclic bond between the 2' position of guanosine and the 5' position of adenosine, with additional phosphodiester linkages. This molecule serves as a potent endogenous agonist of the STING (stimulator of interferon genes) pathway, which is crucial for innate immune activation. Upon binding to STING, 2',3'-cGAMP triggers a cascade of signaling events that culminate in the production of type 1 interferons (IFN-1), thereby enhancing the immune response against pathogens and tumors (PMID:40585794 ). It is particularly significant in the context of certain genetic variants, such as the hSTING-R232H variant, where modified forms like C4'-Me-modified 2',3'-cGAMP demonstrate enhanced immunogenicity, suggesting potential therapeutic applications in infections, cancer, and autoimmune diseases (PMID:40985216 ). Thus, 2',3'-cGAMP and its derivatives represent promising candidates for STING-targeted immunotherapy, especially for patients with specific STING variants that exhibit impaired responses to native 2',3'-cGAMP (PMID:40985216 ).
