AS2863619 enables conversion of antigen-specific effector/memory T cells into Foxp3+ regulatory T (Treg) cells for the treatment of various immunological diseases. AS2863619 is a potent, orally active cyclin-dependent kinase 8 (CDK8) and CDK19 inhibitor with IC50s of 0.61 nM and 4.28 nM, respectively. STAT5 activation enhanced by AS2863619 inhibition of CDK8/19, which consequently activates the Foxp3 gene.

In Vitro

AS2863619 (1 μM; 22 hours; mouse CD4+ T cells) treatment suppresses serine phosphorylation of the PSP motif of STAT5b to ~40% while enhancing tyrosine phosphorylation in the C-terminal domain to ~160% of control-treated samples[1].

Western Blot Analysis[1]

Cell Line: Mouse CD4+ T cells
Concentration: 1 μM
Incubation Time: 22 hours
Result: Suppressed serine phosphorylation of the PSP motif of STAT5b to ~40% while enhancing tyrosine phosphorylation in the C-terminal domain to ~160% of control-treated samples.
In Vivo

AS2863619 (30 mg/kg; oral administration; daily; for 2 weeks; mice) treatment after sensitization with 2,4-dinitrofluorobenzene (DNFB) dampens the degree of the secondary response, with milder infiltration of inflammatory cells into the skin and decreases ratios of interferon-γ+ (IFN-γ+) cells in a skin contact hypersensitivity model, when compared with vehicle-treated control mice. Treg depletion before the elicitation of the secondary response abolishes AS2863619-induced suppression. KLRG1+ Foxp3+ T cells are specifically increased in DNFB sensitized AS2863619-treated mice[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.

  • Protocol 1

    Add each solvent one by one:  5% DMSO    40% PEG300    5% Tween-80    50% Saline

    Solubility: ≥ 2.62 mg/mL (6.47 mM); Clear solution

  • Protocol 2

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
