3’3’-cGAMP Fluorinated (c-[2'FdGMP]-[2'FdAMP]) is a synthetic analog of cyclic guanosine monophosphate- adenosine monophosphate (cyclic GMP-AMP, cGAMP) with a fluorine atom at 2’ position of the nucleosides. 3’3’-cGAMP is a cyclic di-nucleotide produced by bacteria. It is also referred to as "canonical" cGAMP due the presence of the classical 3’-5’ phosphodiester linkages between the guanosine and the adenosine. It has been reported that cGAMP binds STING (stimulator of IFN genes) and subsequently induces TBK1-IRF3-dependent production of IFN-β [1]. 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, 3’3’-cGAMP Fluorinated induces higher levels of type I IFNs than does cGAMP. STING ligands such as cGAMP induce type I IFNs and activate interferon stimulated genes (ISG) through IRFs. To facilitate their study, InvivoGen has developed stable reporter cells in two well established immune cell models: THP-1 human monocytes and RAW 264.7 murine macrophages. These cells express a reporter gene (SEAP or Lucia luciferase), under control of an IRF-inducible promoter.

STING agonist 22 is a novel, non-nucleotide specific small-molecule STING agonist with IC50 of 28, 11 uM for human STING isoforms WT and HAQ, respectively.STING agonist 22 did not show any cytotoxicity in an immune cell proliferation panel across a variety of immune cell types and also did not show any activity in a kinome panel.STING agonist 22 introduced higher levels of iFIT3 and MX1 mRNA across three different donors possessing different STING genotypes: WT/WT, WT/HAQ, and WT/R232H in human PBMCs (IC50=5-35 uM).STING agonist 22 demonstrated in vivo antitumor effect in an MC38 mice model, with STING pathway activation and production of type I IFNs and proinflammatory cytokines, serum levels of IL-6, G-SCF, and MIP-1β.

CDN-A is a cyclic di-nucleotide, it can be used to synthesis antibody-drug conjugate (ADC). Cyclic di-nucleotides are potent stimulators of innate and adaptive immune responses. In humans, cyclic di-nucleotide, which are either produced endogenously in response to foreign DNA or by invading bacterial pathogens, trigger the innate immune system by activating the expression of interferon genes.
