UM-259 hydrochloride
Based on 1 Customer Validation
UM-259 hydrochloride is a STING inhibitor with activity against both murine and human STING (including the STINGR232 mutant). UM-259 hydrochloride inhibits STING-dependent signaling pathways, blocks STING oligomerization, and acts on human primary CD14+ monocytes. UM-259 hydrochloride can be used for research on amyotrophic lateral sclerosis, lupus erythematosus, Aicardi-Goutières syndrome, and infant-onset STING-associated vasculopathy.

Description
In Vitro
UM-259 hydrochloride (0.08-40 μM; 1 h + 24 h; diABZI) inhibits STING-dependent signaling pathways in THP1-Dual KI-hSTING-R232 cells, with an EC50 of 1.50 μM[1].
UM-259 hydrochloride (0.2-5 μM; 1 h + 2 h; diABZI) dose-dependently inhibits diABZI-induced IFNβ and IL6 gene expression in iBMDM, and exhibits superior potency to LB244 (HY-156117) at a concentration of 5 μM[1].
UM-259 hydrochloride (0.2-5 μM; 1 h +24 h; diABZI) dose-dependently inhibits diABZI-induced IFNβ secretion in iBMDMs, and its efficacy at 5 μM is superior to that of LB244[1].
UM-259 hydrochloride (2.5 μM; 1 h + 16 h; diABZI) inhibits diABZI-induced IFNβ secretion in primary human CD14+ monocytes[1].
UM-259 hydrochloride (5 μM; 1 h+0-120 min; diABZI) inhibits diABZI-induced phosphorylation of TBK1 and IRF3 in wild-type bone marrow-derived macrophages (BMDMs)[1].
UM-259 hydrochloride (5 μM; 1 h+30 min; diABZI) blocks diABZI-induced STING oligomerization in wild-type bone marrow-derived macrophages (BMDMs)[1].
UM-259 hydrochloride (0.2-5 μM; 24 h) exhibits only limited cytotoxicity against iBMDMs[1].

Cell Line:primary human CD14+ monocytes
-
Concentration:2.5 μM
-
Incubation Time:1 h pre-incubation, followed by 16 h incubation with diABZI
-
Result:Blocked diABZI-induced IFNβ secretion, reducing levels to near baseline (DMSO without diABZI) levels.
-
Cell Line:wild-type bone marrow-derived macrophages (BMDMs)
-
Concentration:5 μM
-
Incubation Time:1 h pre-incubation, followed by 0-120 min incubation with diABZI
-
Result:Inhibited diABZI-induced phosphorylation of TBK1 and IRF3, reducing phosphorylated protein levels compared to vehicle-treated cells at all time points tested.
Blocked diABZI-induced STING oligomer formation, with only STING monomers detected in native fractions (similar to unstimulated cells), while vehicle-treated cells showed robust STING oligomer formation.

In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (4.18 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (4.18 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
