生物活性

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.

体外研究

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.

Western Blot Analysis

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.
体内研究

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.

Animal Model: Mice with DNFB-induced contact skin hypersensitivity
Dosage: 30 mg/kg
Administration: Oral administration; daily; for 2 weeks
Result: The degree of the secondary response, with milder infiltration of inflammatory cells into the skin and decreased ratios of interferon-γ (IFN-γ) cells.
