Tofacitinib citrate inhibits IL-2-mediated human T cell blast proliferation and IL-15-induced CD69 expression with IC50 of 11 nM and 48 nM, respectively. Tofacitinib citrate prevents mixed lymphocyte reaction with IC50 of 87 nM. Tofacitinib citrate inhibits interleukin-6-induced phosphorylation of STAT1 and STAT3 with IC50 of 23 nM and 77 nM, respectively. Tofacitinib citrate decrease a delayed-type hyper-sensitivity response and extended cardiac allograft survival in murine models. CP-690,550 induced a significant pro-apoptotic effect on murine FDCP-EpoR cells carrying JAK2(V617F), whereas a lesser effect was observed for cells carrying wild-type JAK2.

| Cell Experiment | |
|---|---|
| Cell lines | FDCP-EpoR JAK2WT and JAK2V617F cell lines |
| Preparation method | Using identical culture conditions for both FDCP-EpoR JAK2WT and JAK2V617F cell lines perform determination of growth inhibition by Tofacitinib citrate is performed. Briefly, culturing 1 × 105 cells/mL in 96-well flat-bottom plates at 37 °C in a humidified 5% CO2 atmosphere using RPMI 1640 supplemented with 1.25% FCS, and 5% WEHI supernatant. It's necessary to prevent binding between Tofacitinib citrate and serum proteins to decrease FCS concentration . Terminating growth inhibition assays by addition of 20 μL CellTiter96 One Solution Reagent. Incubating Flat-bottom plates for an additional 3 hours for MTT assay. Determining absorbance at 595 nm on a BioTek Synergy-HT microplate reader. Results are the average standard deviation of three independent determinations. |
