Protocol

Cell experiment [1]:

Cell lines

Human T cells and human myelomonocytic cell line HUO3

Preparation method

The solubility of this compound in DMSO is > 15.6 mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 °C for several months.

Reacting condition

0 ~ 4000 nM; 4 days

Applications

In human T cell blasts induced by IL-2, CP-690550 inhibited cell proliferation with an IC50 value of 11 nM. In human myelomonocytic HUO3 cells induced by GM-CSF, CP-690550 inhibited cell proliferation with an IC50 value of 324 nM.

Animal experiment [1]:

Animal models

Heterotopic heart transplantation mouse model

Dosage form

0 ~ 136 ng/mL; osmotic minipump infusion

Applications

In a heterotopic heart transplantation mouse model, CP-690550 dose-dependently increased survival of transplanted hearts. Mice received CP-690550 at the concentration of ~ 60 ng/mL maintained their grafts for > 28 days.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Background

Tofacitinib, also named CP-690550 orTasocitinib, is a novel oral Janus kinase inhibitor which is being used as a targeted immune-modulator. It primarily inhibits signaling through heterodimeric receptors associated with JAK3, JAK1, or both of them, with functional selectivity over JAK2-paired receptors. Inhibition of JAK1 and JAK3 by tofacitinib blocks signaling for several cytokines, including interleukins 2, 4, 7, 9, 15, and 21. These cytokines are integral to lymphocyte activation, function, and proliferation. Tofacitinib is also an inhibitor of STAT molecules. Recent efforts to investigate the mechanism of action have shown that tofacitinib interacts with multiple JAKs and presumably other kinases
