STING-IN-8
STING-IN-8 (Compound 15b) emerges as a potent stimulator of interferon gene (STING) inhibitor with an IC50 value of 0.121 μM in human and an IC50 value of 0.033 μM in mouse. STING-IN-8 inhibits MSA-2 (HY-136927) or 2’, 3’ -cGAMP (HY-100564)-stimulated STING signaling and suppresses immune-inflammatory cytokine levels in both human and murine cells. STING-IN-8 is promising for research in the field of STING-associated inflammatory and autoimmune diseases.

Biological Activity
STING-IN-8 (0.1, 0.3, 1, 3 μM, 5 h) restrains the MSA-2 (10 μM) or 2’, 3’-cGAMP (10 μM) -induced p-TBK1 and p-IRF3 upregulation expression in both human and murine cells[1]. STING-IN-8 shows negligible cytotoxicity with CC50 of 30 μM in THP1-Dual and RAW-Lucia cells[1]. STING-IN-8 (0.3, 1, 3 μM and 0.1, 1, 3 μM, 9 h) effectively inhibits STING downstream immune-inflammatory cytokines in both human and mouse immune cells[1].
