Homogeneous suspension	CMC-NA	≥5mg/ml	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution	5%DMSO 1 Corn oil Validated by Selleck labs. Should you need adjustments to this formulation, contact our sales team for custom testing.	5.000mg/ml (10.81mM)	Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description

SN-011 is a STING-specific inhibitor with an IC50 of 76 nM.

Targets

STING

76 nM

In vitro

SN-011 substantially suppresses 2′3′-cGAMP-induced STING oligomerization and phosphorylation assessed by immunoblot in HFFs. This compound specifically inhibits STING activation and STING-dependent signalling.

In Vivo

Serum antinuclear antibody is markedly reduced by SN-011 treatment. This compound also significantly reduces the number of activated CD69⁺ CD8 T cells and memory CD44^high CD62L^low CD4 and CD8 T cells to near normal levels in the spleens of treated Trex1^−/− mice. It strongly reduces inflammation and protects Trex1^−/− mice from death.

Protocol (from reference)

Cell Assay:^{^[1]}	Cell Lines HFFs Concentrations 1 μM - 10 μM Incubation Time 24 h Method HFFs are harvested and lysed in lysis buffer with brief sonication. Cell lysate is collected and incubated with biotin (5 μM). For purified recombinant STING-CTD protein, 0.05 mg protein in 400 μL buffer (25 mM Tris-HCl, pH 7.5, 150 mM NaCl) was incubated with biotin (5 μM) for 1 h at 4 °C. Then the protein of interest was pull-down by streptavidinconjugated agarose and detected by immunoblot analysis.
