STING18

STING18 is a competitive ligand of stimulator of interferon genes (STING, IC50 = 0.068 µM in a radioligand binding assay). It inhibits cGAMP-induced IFN-beta production (IC50 = 11 µM) but does not stimulate IFN-beta production (EC50 = >30 µM) in THP-1 cells.Formal Name: 2-[3-chloro-4-(1,1-dimethylethyl)phenyl]-3-(2,3-dihydro-1,4-benzodioxin-6-yl)-7-fluoro-1,2,3,4-tetrahydro-1-oxo-4-isoquinolineacetic acid. CAS Number: 2706536-26-5. Synonyms: Stimulator of Interferon Genes 18. Molecular Formula: C29H27ClFNO5. Formula Weight: 524.0. Purity: >98%.
