Description

Delgocitinib (JTE-052) is a specific JAK inhibitor with IC50s of 2.8, 2.6, 13 and 58 nM for JAK1, JAK2, JAK3 and Tyk2, respectively[1].

IC50 & Target[1]

JAK2

2.6 nM (IC50)

JAK1

2.8 nM (IC50)

JAK3

13 nM (IC50)

Tyk2

58 nM (IC50)

In Vitro

In the enzymatic assays, Delgocitinib potently inhibits all of the JAK subtypes with IC50 values of 2.8±0.6, 2.6±0.2, 13±0 and 58±9 nM for JAK1, JAK2, JAK3 and Tyk2, respectively. Lineweaver-Burk plots show that the inhibition mode of Delgocitinib toward all JAKs is competitive with ATP with Ki values of 2.1±0.3, 1.7±0.0, 5.5±0.3 and 14±1 nM for JAK1, JAK2, JAK3 and Tyk2, respectively. In these cell-based cytokine signaling assays, Delgocitinib inhibits the phosphorylation of Stat proteins induced by IL-2, IL-6, IL-23, GM-CSF, and IFN-α with IC50 values of 40±9, 33±14, 84±11, 304±22 and 18±3 nM, respectively. Delgocitinib also inhibits IL-2-induced proliferation of T cells in a concentration-dependent manner (IC50=8.9±3.6 nM), and its potency is similar to that of CP-690550 (IC50=16 nM)[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Delgocitinib decreases the IFN-γ production, but the potency of the 1-h prior administration is higher than that of the 6-h prior administration (ED50=0.24 versus 1.3 mg/kg). In the administration from day 1, Delgocitinib prevents the development of hind paw swelling and histological changes of inflammatory cell infiltration and synovial cell hyperplasia. Delgocitinib inhibits radiographic and histological changes of bone destruction and cartilage destruction. In the administration from day 15, Delgocitinib decreases the paw swelling in a dose-dependent manner. In addition, Delgocitinib ameliorates the inflammatory cell infiltration, synovial cell hyperplasia, and cartilage/bone destructions in the histological and radiographic examinations at the end of the study[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: ≥ 2.5 mg/mL (8.06 mM); Clear solution

  • Protocol 2

    Add each solvent one by one:  5% DMSO    95% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (8.06 mM); Clear solution

Cell Assay
[1]

For determination of IL-2-induced T cell proliferation, human T cells are precultured with 10 μg/mL PHA-M for 3 days and plated in 96-well plates at 1.0×104 cells/well in the presence or absence of various concentrations of Delgocitinib. Following preincubation with Delgocitinib for 30 min at 37°C, the cells are stimulated by adding 20 ng/mL recombinant human IL-2 to each well and incubated for 3 days at 37°C under 5 % CO2. After completion of the culture period, the cells are harvested with a 96-well harvester and counted in a scintillation counter[1].

Animal Administration
[1]

Lewis rats are used in this study. First, collagen-induced arthritis (CIA) is induced in rats. Lewis rats are immunized with 1 mL of the emulsion (1 mg of type II collagen) via ten intradermal injections on the back under anesthesia. The rats are then challenged with 0.2 mL of the emulsion injected into the base of the tail on day 8 under anesthesia. Delgocitinib is given orally once daily from day 1 to day 21 (preventive administration) or from day 15 to day 28 (therapeutic administration). After arthritis induction, the hind paw volume is measured by a water displacement method using a plethysmometer. On day 22 or day 29, the rats are euthanized, and their hind paws are excised and X-rayed or processed for histological evaluation[1].

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.
