An activator of the STING pathway; induces secretion of IFN-β in human PBMCs (EC50 = 130 nM); increases serum levels of Ifn-β, Il-6, Tnf, and Cxcl1 in wild-type, but not Sting-/-, mice at 2.5 mg/kg; inhibits the cytopathic effect of HCoV-229E in infected MRC-5 cells (EC50 = 3 nM); decreases the levels of SARS-CoV-2 RNA in primary human bronchial airway epithelial cells in an air-liquid interface assay; decreases tumor volume and increases survival in a CT26 murine colorectal cancer model at 3 mg/kg; this compound is expected to exist in one or both tautomeric forms
