BRD6989
Based on 2 publication(s) in Google Scholar
BRD6989, an analog of the natural product cortistatin A (dCA), inhibits CDK8 and upregulates IL-10. BRD6989 selectively binds a complex of CDK8 with an IC50 of ~200 nM. BRD6989 inhibits the kinase activity of recombinant CDK8 or CDK19 complexes.

IL-10 |
Pretreatment of BMDCs with BRD6989 (0-100 μM; for 48 hours) increases IL-10 production with an EC50 of ~1 μM[1].
BRD6989 (0.6, 1.7, 5, 15 μM) suppresses phosphorylation of the STAT1 transactivation domain at Ser727 in IFNγ-stimulated BMDCs[1].
BRD6989 (5 µM; ~2 hours) suppresses induction of STAT1–STAT2 activity and NF-κB activation to a varying degree after stimulation of BMDMs[1].
BRD6989 (5 µM; 24 hours) enhances IL-10 production in activated human and murine macrophages and dendritic cells[1].

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
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.
Please enter the basic information of animal experiments:

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
