BrdU assay for the proliferation of WP1066- treated UM1 and Tca8113 cells (P<0.05).
Clin Cancer Res, 2018, 24(11):2665-2677. WP1066 purchased from Selleck.
(A) HRMECs were treated with IL-6 for 48 hours in the presence and the absence of WP1066. The protein expression and localization of ZO-1 was examined by immunofluorescence staining. Each tight junction protein was doubleimmunostained with anti-CD31 antibody for defining the cell boundaries. Nuclei were labeled with DAPI. Arrow heads indicate the intact tight junction protein at cell boundaries. Scale bars are equal to 50 μm. Right histograms: quantitative analysis of each tight junction protein expression by evaluating the fluorescence intensity using with ImageJ software. The results are fold increases versus control and plotted as the means ± SD (n = 5). * P < 0.05 between two values.

Effects of selective STAT3 inhibitors on adherent glioma CSCs. Cells were treated with WP1066 (50 uM for 2 h) or vehicle, and colocalization of STAT3 and p65 was determined by immunostaining.

(A) NF-YA, STAT3, pY-STAT3, VEGF and β-actin protein levels were detected by western blot analysis in vector control or NF-YA stably overexpressed (or NF-YA stably overexpressed plus STAT3 inhibitor WP1066 treatment) A375P/Malme-3M cells.

|Description||WP1066 is a novel inhibitor of JAK2 and STAT3 with IC50 of 2.30 μM and 2.43 μM in HEL cells; shows activity to JAK2, STAT3, STAT5, and ERK1/2 not JAK1 and JAK3. Phase 1.|
|Features||Similar to its parent compound AG490, WP1066 inhibits the phosphorylation of JAK2, but unlike AG490, WP1066 also degraded JAK2 protein.|
WP1066 markedly inhibits the growth of HEL cells carrying the JAK2 V617F mutant isoform in a dose-dependent manner with IC20, IC50 and IC80 of 0.8, 2.3 and 3.8 μM. WP1066 at concentrations of 0.5, 1.0, 2.0, 3.0, or 4.0 μM inhibits the phosphorylation of JAK2, STAT3, STAT5, and ERK1/2 without affecting the phosphorylation of JAK1 and JAK3 in erythroid leukemia HEL cells that express the JAK2 V617F isoform.  WP1066 at concentrations ranging from 0.5 to 3.0 μM inhibits the proliferation of AML colony-forming cells obtained from patients and that of the AML cell lines OCIM2 and K562 in a dose-dependent manner. WP1066 at concentrations of 0.5, 1.0, 2.0, 3.0, or 4.0 μM dose-dependently decreases JAK2 and pJAK2 protein levels as well as downstream phosphorylation levels of STAT3, STAT5, and AKT in OCIM2 and K562 cells. WP1066 at concentrations of 2 μM inhibits OCIM2 cell multiplication by inducing accumulation of cells at the G0-G1 phase of the cell cycle. WP1066 at concentrations of 1, 2, or 3 μM induces apoptosis in both OCIM2 and K562 cells in a dose-dependent fashion by activating procaspase-3 and cleaving PARP.  WP1066 at concentrations of 5 μM prevents the phosphorylation of STAT3, and at concentrations of 2.5μM WP1066 significantly inhibits cell survival and proliferation in Caki-1 and 786-O renal cancer cells. WP1066 at concentrations of 5 μM suppresses HIF1α and HIF2α expression and VEGF production in Caki-1 and 786-O renal cancer cells. 
|In vivo||WP1066 orally administrated at dose of 40 mg/kg once daily for 19 days significantly inhibits the tumours growth in Caki-1 xenograft mice, with decreased immunostaining of phosphorylated STAT3 and reduced length of CD34-positive vessels. |

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × 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).
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).

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.
