UM-259 is a STING inhibitor with an EC50 of 1.50 μM in THP1-Dual cells expressing wild-type STING. It blocks STING oligomerization and inhibits diABZI-induced phosphorylation of TBK1 and IRF3, thereby suppressing the transcription of IFNβ and IL6, and reducing IFNβ secretion. UM-259 can be used to study STING-dependent inflammation and neurological disorders.

Product Introduction

Bioactivity

Description

In vitro

UM-259 (0.2-5 μM, pretreated for 1 hour) effectively inhibits diABZI-induced IFNβ and IL6 gene transcription in iBMDMs. Additionally, UM-259 (2.5 μM, pretreated for 1 hour) demonstrates strong activity in blocking STING-dependent IFNβ secretion in primary human CD14+ monocytes. Moreover, UM-259 (5 μM, pretreated for 1 hour) significantly inhibits diABZI-induced TBK1 and IRF3 phosphorylation, efficiently suppressing STING oligomerization and downstream signaling in WT BMDMs.

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, TargetMol | Animal experiments

and a total of 10 animals are to be administered, using a formulation of TargetMol | reagent

10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH₂O , the resulting working solution concentration would be 2 mg/mL.

Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSO TargetMol | reagent to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSO TargetMol | reagent stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.

2) Add 50 μL Tween 80 and mix well until fully clarified.

3) Add 450 μL Saline,PBS or ddH₂O TargetMol | reagent and mix thoroughly until a homogeneous solution is obtained.

This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.

All co-solvents required for this protocol, includingDMSO, PEG300/PEG400, Tween 80, SBE-β-CD, and Corn oil, are available for purchase on the TargetMol website.
