STING agonist-23 

STING agonist-23 (CF502) is a non-nucleotide small-molecule STING agonist. STING agonist-23 activates STING, increases phosphorylation of STING, TBK1 and IRF3. STING agonist-23 promotes the levels of IFN-β, IL-6, CXCL-10, TNF-α, ISG-15, and CCL-5 in tumor cells. STING agonist-23 exhibits activity against SARS-CoV series strains^[1].

STING agonist-23 (10 μM; 3 h or 5 h) increases the level of phosphorylated STING, TBK1 and IRF3 following 3-h incubation, increases the level of IFN-β, IL-6, CXCL-10, TNF-α, ISG-15 following 5-h incubation, and CCL-5, in THP-1 cells^[1].

STING agonist-23 adjuvant (20?μg STING agonist-23 and 5 μg RBD-Fc per mouse; im; 3 times at 14-day intervals) induces strong antibody immune response induced by the SARS-CoV-2 RBD-Fc protein in mice model^[1].
