DDO-6513
Based on 1 Customer Validation
DDO-6513 is a STING molecular glue inhibitor with an IC50 of 1.93 μM. DDO-6513 selectively targets human STING but not murine STING, and exhibits a Kd value of 151 nM for human STING. DDO-6513 induces aberrant head-to-head STING oligomerization and disrupts the formation of normal signal-competent linear STING polymers. DDO-6513 inhibits STING-dependent downstream activation of TBK1 and IRF3, and suppresses the expression of proinflammatory cytokines. DDO-6513 can be used for research on STING-related autoinflammatory diseases.

In Vitro
DDO‑6513 (3.13‑50 μM; 12‑24 h) does not exhibit significant cytotoxicity in THP‑1 and WI‑38 cells[1].
DDO‑6513 (5-20 μM; 24 h) blocks the recruitment of TBK1 to STING in cGAMP-stimulated THP-1 and HFF cells, reduces the phosphorylation levels of TBK1 and IRF3, and inhibits IRF3 dimerization and nuclear translocation[1].
DDO‑6513 induces the formation of high-order abnormal oligomers in purified human STING-CTD protein in vitro[1].
DDO‑6513 (20 μM; 12-24 h) induces the formation of STING punctate aggregates and blocks the trafficking of STING from the endoplasmic reticulum to the Golgi apparatus in HeLa and WI‑38 cells overexpressing GFP‑STING[1].
DDO‑6513 (10 μM; 24 h) reduces the elevated expression levels of ISG-related genes in PBMCs derived from AGS, DM, and SLE donors[1].

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: ≥ 5 mg/mL (13.45 mM); Clear solution
This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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.
