Activité biologique

Description WP1066 est un nouvel inhibiteur de JAK2 et STAT3 avec des IC50 de 2,30 μM et 2,43 μM dans les cellules HEL ; il montre une activité envers JAK2, STAT3, STAT5 et ERK1/2 mais pas JAK1 et JAK3. WP1066 induit l'apoptose. Phase 1.

In vitro 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. This compound 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. It 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. This chemical 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. It at concentrations of 2 μM inhibits OCIM2 cell multiplication by inducing accumulation of cells at the G0-G1 phase of the cell cycle. This compound 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. It at concentrations of 5 μM prevents the phosphorylation of STAT3, and at concentrations of 2.5μM it significantly inhibits cell survival and proliferation in Caki-1 and 786-O renal cancer cells. This chemical 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.
Caractéristiques Similaire à son composé parent AG490, le WP1066 inhibe la phosphorylation de JAK2, mais contrairement à l'AG490, le WP1066 dégrade également la protéine JAK2.

  • Concentrations

  • Méthode

    The 3, [4,5-dimethylthiazol-2-yl]-5-[3-carboxymethoxyphenyl]-2-[4-sulfophenyl]-2H-tetrazolium (MTT) assay is done using an MTT-based cell proliferation/cytotoxicity assay system. Briefly, fresh low-density peripheral blood cells and various cell lines at the logarithmic phase of their growth are washed twice in RPMI 1640 containing 10% FCS and counted in a hemocytometer. Cell viability is assessed by the trypan blue (0.1%) staining method. Equal numbers of viable cells (5 × 104 per well) are incubated in a total volume of 100 μL of RPMI 1640 supplemented with 10% FCS alone or with this compound at increasing concentrations; the incubations are continued for up to 72 h in 96-well flat-bottomed plates at 37 °C in a humidified 5% CO2 atmosphere. Experiments for each condition are done in triplicate. After incubation, 20 μL of CellTiter96 One Solution Reagent are added to each well. The plates are then incubated for an additional 60 min at 37 °C in a humidified 5% CO2 atmosphere. Immediately after incubation, absorbance is read using a 96-well plate reader at a wavelength of 490 nm.

(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.
