Biological Activity

Description

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

Targets

STING ^[1]

76 nM

In vitro
In vitro	SN-011 substantially suppresses 2′3′-cGAMP-induced STING oligomerization and phosphorylation assessed by immunoblot in HFFs. SN-011 specifically inhibits STING activation and STING-dependent signaling.^[1]
Cell Research	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.

In Vivo
In vivo	Serum antinuclear antibody is markedly reduced by SN-011 treatment. SN-011 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. SN-011 strongly reduces inflammation and protects Trex1^−/− mice from death.^[1]
Animal Research	Animal Models	Trex1^−/− mice
	Dosages	5 mg/kg, 10 mg/kg
	Administration	i.p.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
