Description AS2863619 is a small-molecule cyclin-dependent kinase CDK8/19 inhibitor with IC50 of 0.6099 nM and 4.277 nM, respectively. AS2863619 is a potent Foxp3 inducer in Tconv cells.

In vitro

AS2863619 induction of Foxp3 in vitro does not require exogenous TGF-β. AS2863619-induced iTreg cells can be induced in the presence of inflammatory cytokines such as IL-4, IL-6, and IFN-γ, which appear to hamper Foxp3 gene activation via activation of STATs. AS2863619 is able to generate iTreg cells not only from naïve Tconv cells but also from effector/memory Tconv cells. Furthermore, AS2863619 cannot induce Foxp3 in CDK8 and CDK19 double-deficient T cells. AS2863619-induced iTreg cells require TCR and IL-2 stimulation for their generation and are devoid of Treg-type DNA hypomethylation, which is present in nTreg cells and required for stable Treg function.[1]

In vivo

AS2863619 induces in vivo Foxp3 induction in antigen-activated T cells. In vivo AS2863619-induced Foxp3+ T cells are able to gradually acquire Treg-specific epigenetic alterations, differentiating into functionally stable Foxp3+ pTreg cells having a more nTreg-like gene expression profile.[1]

Protocol (from reference)

Cell Research:

[1]

  • Cell lines: PBMCs, Human CD4+ T cells, lymph node cells derived from eFox mice
  • Concentrations: 1.0 μM
  • Incubation Time: 24 h, 0-44 h
  • Method:

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
