产品描述

Bosutinib is a synthetic quinolone derivative and dual kinase inhibitor that targets both Abl (IC50: 1 nM) and Src (IC50: 1.2 nM) kinases.

靶点活性

Abl    c-Src    MAPK

体外活性

Bosutinib has the antiproliferative activity against three different Bcr-Abl-positive leukemia cell lines (KU812, K562, and MEG-01). Bosutinib inhibited the proliferation of all three cell lines, with IC50s ranging from 5 nM in the KU812 line to 20 nM for the K562 and MEG-01 cell lines. Inhibition of proliferation by Bosutinib is associated with cell cycle arrest and cell death. Treatment with Bosutinib at 100 nM for 24 h (KU812) or 48 h (K562) resulted in a reduction of S and G2-M phase cells and an increase of cells with a DNA content of less than 2N. Treatment with Bosutinib at 100 nm also led to PARP degradation after 48 h. The potent antiproliferative activity of Bosutinib against CML lines was not a general property for leukemia cell lines. Molt-4, HL-60, Ramos, and other leukemia cell lines were unaffected by Bosutinib at concentrations less than 1 μM [2].

体内活性

Bosutinib (30/25 mg/kg, b.i.d) reduces tumor growth in unstaged and staged Src-transformed fibroblast mouse xenograft models. Bosutinib (100 mg/kg) also induces complete tumor regression in a K562 mouse xenograft model when administered once per day for five days [2].

激酶实验

The Src and Abl kinase assays: The Src kinase activity is measured in an ELISA format. Src (3 units/reaction), reaction buffer (50 mM Tris-HCl pH 7.5, 10 mM MgCl2, 0.1 mM EGTA, 0.5 mM Na3VO4) and cdc2 substrate peptide are added to various concentration of Bosutinib and incubated at 30 °C for 10 minutes. The reaction is started by the addition of ATP to a final concentration of 100 μM, incubated at 30 °C for 1 hour and stopped by addition of EDTA. Instructions from the manufacturer are followed for subsequent steps. The Abl kinase assay is performed in a DELFIA solid phase europium-based detection assay format. Biotinylated peptide (2 μM) is bound to streptavidin-coated microtitration plates for 1.5 hours in 1 mg/mL ovalbumin in PBS. The plates are washed for 1 hour with PBS/0.1% Tween 80, followed by a PBS wash. The kinase reaction is incubated for 1 hour at 30°C. Abl kinase (10 units) is mixed with 50 mM Tris-HCl (pH 7.5), 10 mM MgCl2, 80 μM EGTA, 100 μM ATP, 0.5 mM Na3VO4, 1% DMSO, 1 mM HEPES (pH 7.0), 200 μg/mL ovalbumin and various concentration of Bosutinib. The reaction is stopped with EDTA at a final concentration of 50 mM. The reaction is monitored with Eu-labeled phosphotyrosine antibody and DELFIA enhancement solution.

细胞实验

Cells are exposed to various concentrations of Bosutinib for 72 hours. Anchorage-independent proliferation of Abl-MLV-transformed fibroblasts is measured in 96-well ultra-low binding plates treated with Sigmacote to block residual cell attachment. Cell proliferation is measured with MTS or Cell-Glo. For the determination of cell cycle or cell death, cells are prepared for FACS analysis in the CycleTest Plus DNA reagent kit and analyzed on a fluorescence-activated cell sorter flow cytometer. (Only for Reference) Cell lines: Abl-MLV, Rat 2, KU812, K562, and MEG-01 cells
