生物活性

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[1].

体外研究
(In Vitro)

STING-IN-8 (0.1, 0.3, 1, 3 μM, 5 h) 抑制人和鼠细胞中 MSA-2 (10 μM) 或 2’, 3’ -cGAMP (10 μM) 诱导的 p-TBK1 和 p-IRF3 上调表达[1]
STING-IN-8 在 THP1-Dual 和 RAW-Lucia 细胞系中 CC50 为 30 μM 时显示出可忽略的细胞毒性[1]
STING-IN-8 (0.3, 1, 3 μM 和 0.1, 1, 3 μM, 9 h) 在人和小鼠免疫细胞中有效抑制 STING 下游免疫炎症细胞因子[1]

Western Blot Analysis[1]

Cell Line: Human monocyte derived THP1-Dual cell line, murine macrophage cells and mouse embryonic fibroblasts
Concentration: 0.1, 0.3, 1, 3 μM
Incubation Time: 5 h
Result: Significantly down-regulate the the levels of phosphorylated TBK1 and IRF3 induced by MSA-2 (10 μM) and 2’, 3’ -cGAMP (10 μM) in all cell lines with better potency than SN-011 (HY-145010).

Real Time qPCR[1]

Cell Line: THP1-Dual cell line and RAW-Lucia cells
Concentration: 0.3, 1, 3 μM and 0.1, 1, 3 μM
Incubation Time: 9 h
Result: Significantly inhibited the MSA-2 (10 μM) or 2’, 3’-cGAMP (10 μM)-induced upregulation of STING signals expression in THP1-Dual cell line and RAW-Lucia cells.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
