STING (Stimulator of Interferon Genes) is a transmembrane protein localized to the endoplasmic reticulum that undergoes a conformational change in response to direct binding of cyclic dinucleotides (CDNs), resulting in a downstream signaling cascade involving TBK1 activation, IRF-3 phosphorylation, and production of IFN-β and other cytokines. STING is a pattern recognition receptor of cyclic dinucleotides as well as an innate immune adaptor protein that enables signaling from cytoplasmic receptors to the transcription factor interferon regulatory factor 3. Initiation of these pathways leads to the expression of type I interferons and proteins associated with antiviral and antitumor immunity. Small molecules capable of triggering STING-dependent cellular processes are effective at blocking virus replication, enhancing vaccine efficacy, and facilitating immune response to cancer cells.

G10 potently blocks replication of Alphavirus species Venezuelan Equine Encephalitis Virus (VEEV) (IC90 = 24.57 μM). IC50 value: 24.57 μM (IC90)Target: VEEV, STINGin vitro: G10 does not bind to STING directly, however, G10 represents the first synthetic small molecule characterized as an indirect activator of human STING-dependent phenotypes.100 μM G10 (a concentration over twelve times the IC90 for CHIKV and over four times the IC90 for VEEV). G10 induces IFN/IRF3- but not NF-κB-dependent transcription in human fibroblasts. G10 Induces IFN/IRF3- but not NF-κB-Dependent Transcription in Human Fibroblasts. G10 activates IRF3, but not canonical NF-κB pathways in human fibroblasts. G10 elicits antiviral activity against New and Old World Alphaviruses. G10 stimulates phosphorylation of IFN regulatory factor 3 (IRF3) in a manner similar to that triggered by UV-inactivated cytomegalovirus (UV-CMV) and Sendai virus (SeV). G10 induces synthesis and secretion of bioactive type I and III IFNs and generates an antiviral state in fibroblast cells positive for STING, IRF3, and STAT1 proteins. G10 triggers innate immune responses that involve expression of IRF3-dependent genes including type I and III interferons.
