  • Colony-forming assay results showing that the Jak2 inhibitor TG101348 reduces CFU-GM colonies generated from mutant fetal liver R2 cells. Results from 4 independent control or mutant fetal livers treated with TG101348 or dimethylsulfoxide (DMSO) are shown (mean ?SD). ***P < .001.

    Effects of JAK2, STAT3, and STAT1 inhibitor on surface and total expression of PD-L1 in the lung adenocarcinoma cell line HCC4006. JAK2 inhibition suppresses surface and whole expression of PD-L1 in HCC4006 cells. HCC4006 cells were treated for 48 hours with the JAK2 pharmacological inhibitor TG101348 (200 nM or 500 nM) or DMSO. Surface (A) and total (B) expression of PD-L1 were evaluated by flow cytometry. Results are representative of five independent experiments. STAT3 inhibition suppresses total expression of PD-L1 in HCC4006 cells but has no effect on surface expression of PD-L1. HCC4006 cells were treated for 48 hours with the STAT3 pharmacological inhibitor BP-1-102 (0.5 μM or 5 μM) or DMSO. Surface (C) and total (D) expression of PD-L1 were evaluated by flow cytometry. Results are representative of four independent experiments. Asterisks indicate statistically significant differences between the experimental and DMSO-treated cells (*p < 0.05, **p < 0.01, ***p < 0.001).

Biological Activity

Description Fedratinib (SAR302503, TG101348) is a selective inhibitor of JAK2 with IC50 of 3 nM in cell-free assays, 35- and 334-fold more selective for JAK2 versus JAK1 and JAK3. Phase 2.

In vitro

TG-101348 also significantly inhibits JAK2 V617F, Flt3, and Ret with IC50 of 3 nM, 15 nM, and 48 nM, respectively. TG101348 has an IC50 ~300-fold higher for the closely related JAK3 and is a less potent inhibitor of the JAK1 and TYK2 family members. TG101348 inhibits proliferation of a human erythroblast leukemia (HEL) cell line that harbors the JAK2V617F mutation, as well as a murine pro-B cell line expressing human JAK2V617F (Ba/F3 JAK2V617F), with IC50 of 305 nM and 270 nM, respectively. TG-101348 also inhibits proliferation of parental Ba/F3 cells to a comparable level, with IC50 of ~420 nM. TG101348 treatment reduces STAT5 phosphorylation at concentrations that parallel the concentrations required to inhibit cell proliferation. TG101348 induces apoptosis in both HEL and Ba/F3 JAK2V617F cells in a dose-dependent manner. TG101348 does not show proapoptotic activity in control normal human dermal fibroblasts at concentrations up to 10 μM, and the antiproliferative IC50 against fibroblasts is >5 μM. [1] TG101348 treatment decreases GATA-1 expression, which is associated with erythroid-skewing of JAK2V617F+ progenitor differentiation, and inhibits STAT5 as well as GATA S310 phosphorylation. [2] TG101348 inhibits the proliferation of HMC-1.1 (KITV560G) cells, with somewhat lower potency than HMC-1.2 (KITD816V, KITV560G) cells, with IC50 of 740 nM and 407 nM, respectively. [3]

In vivo TG101348 has potential for efficacious treatment of JAK2V617F-associated myeloproliferative diseases (MPD). In treated animals, there is a statistically significant reduction in hematocrit and leukocyte count, a dose-dependent reduction/elimination of extramedullary hematopoiesis, and, at least in some instances, evidence for attenuation of myelofibrosis, correlated with surrogate endpoints, including reduction/elimination of JAK2V617F disease burden, suppression of endogenous erythroid colony formation, and in vivo inhibition of JAK-STAT signal transduction. There are no apparent toxicities and no effect on T cell number. [1] Oral administration of TG101348 (120 mg/kg) significantly inhibits PV progenitor erythroid differentiation in vivo. [2]

Protocol

Kinase Assay:[1]
+ Expand

Cell-free Kinase Activity Assays:

IC50 values for TG101348 are determined commercially using the InVitrogen kinase profiling service for a 223 kinase screen that included JAK2 and JAK2V617F or Carna Biosciences for the screen of all Janus kinase family members including JAK1 and Tyk2. ATP concentration is set to approximately the Km value for each kinase.
Cell Research:[1]
+ Expand
  • Cell lines: EpoBa/F3 JAK2V617F, Ba/F3p210, HEL, and K562
  • Concentrations: Dissolved in DMSO, final concentrations ~10 μM
  • Incubation Time: 72 hours
  • Method: Approximately 2 × 103 cells are plated into microtiter-plate wells in 100 μL RPMI-1640 growth media with indicated concentrations of inhibitor. Following 72 hours incubation with TG101348, 50 μL of XTT dye are added to each well and incubated for 4 hours in a CO2 incubator. The colored formazan product is measured by spectrophotometry at 450 nm with correction at 650 nm. The concentration in which 50% of the effect (i.e., inhibition of proliferation) is observed (IC50) is determined using the GraphPad Prism 4.0 software. All experiments are performed in triplicate, and the results are normalized to growth of untreated cells. Induction of apoptosis of EpoBa/F3 JAK2V617F, Ba/F3p210, HEL, and K562 cells is determined by DNA fragmentation with DMSO and increasing concentrations of TG101348.

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)

  • Mass
    Concentration
    Volume
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

  • C1
    V1
    C2
    V2

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
