11 nM 18 nM 155 nM
In vitro

CYT387 inhibits the proliferation of parental Ba/F3 cells (Ba/F3-wt) stimulated by IL-3 with IC50 of 1400 nM. Furthermore, CYT387 also causes the inhibition of cell proliferation in cell lines constitutively activated by JAK2 or MPL signaling, including Ba/F3-MPLW515L cells, CHRF-288-11 cells and Ba/F3-TEL-JAK2 cells with IC50 of 200 nM, 1 nM and 700 nM, respectively. In addition, CYT387 has been shown to inhibit erythroid colony growth in vitro from JAK2V617F-positive PV patients with similar potency with IC50 of 2μ-4 μM. [1] A recent study shows that CYT387 inhibits PI3K/AKT and Ras/MAPK signaling induced by IL-6 and IGF-1. Moreover, CYT387 induces apoptosis as a single agent and synergizes with the conventional anti-MM therapies bortezomib and melphalan in primary multiple myeloma (MM) cells. [2]

Protocol

Kinase Assay:[1]
+ Expand

Cell-free kinase activity assays:

Glutathione-S-transferase (GST)-tagged JAK kinase domains expressed in insect cells are purified before use in a peptide substrate phosphorylation assay. Assays are carried out in 384-well optiplates using an Alphascreen Protein Tyrosine Kinase P100 detection kit and a PerkinElmer Fusion Alpha instrument.

  • Cell lines: Ba/F3, Ba/F3-JAK2V617F and Ba/F3-MPLW515L cells
  • Concentrations: 0 to 10 μM
  • Incubation Time: 72 hours
  • Method: Ba/F3 cells expressing JAK2V617F (Ba/F3-JAK2V617F) and MPLW515L (Ba/F3-MPLW515L) mutants, as well as CHRF-288-11 (JAK2T875N) and CMK (JAK3A572V) cells are used. The TEL/JAK2 and TEL/JAK3 fusions are generated and introduced into Ba/F3 murine cells. The TEL/JAK2- or TEL/JAK3-transfected cells are cultured in Dulbecco's modified Eagle's medium (DMEM) containing 10% fetal calf serum (FCS). Ba/F3 wild-type cells are cultured in RPMI containing 10% FCS supplemented with 5 ng/mL murine IL-3. Proliferation is measured using the Alamar Blue assay after incubating for 72 hours at 37 °C with 5% CO2(Only for Reference)
