STING Ligand - Difluoro 3'3'-c-di-GMP, cyclic [FdG(3’,5’)pFdG(3’,5’)p]
c-di-GMP Fluorinated (c-di[2’FdGMP]) is a synthetic analog of cyclic diguanylate monophosphate (c-di-GMP) with a fluorine atom at 2’ position of the nucleoside. c-di-GMP is a bacterial second messenger that acts a potent immunostimulant in mammals. It induces production of type I interferons (IFNs) by directly binding to the endoplasmic reticulum-resident receptor STING (stimulator of interferon genes) .
The incorporation of fluorine into biologically active molecules is commonly used in medicinal chemistry to improve their metabolic stability or to modulate physicochemical properties such as lipophilicity [2, 3]. Moreover, the introduction of a fluorine atom can change the biological activities of a molecule. Interestingly, when used at low concentrations in various cellular assays, c-di-GMP Fluorinated induces higher levels of type I IFNs than does c-di-GMP.

THP1-Dual™ cells were stimulated for 24 hours with the STING ligands as shown (all at 10 μg/ml). IRF induction was determined by measuring the relative light units (RLUs) in a luminometer using QUANTI‑Luc™, a Lucia luciferase detection reagent.
THP1-Dual™ cells were stimulated for 24 hours with the STING ligands as shown (all at 10 μg/ml). NF‑kB induction was determined using QUANTI‑Blue™, a SEAP detection reagent, and by reading the optical density (OD) at 655 nm. Non-induced cells (NI) have been included as a negative control.
