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]	- Collapse 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 Research:^[1]	- Collapse 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% CO_{2(Only for Reference)}
Animal Research:^[3]	- Collapse Animal Models: Balb/c mice are transplanted with bone marrow transduced with a JAK2V617F retrovirus. Dosages: ≤50 mg/kg Administration: Administered via p.o. (Only for Reference)

Bio Calculators

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

*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

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 )

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