Description

A 419259 trihydrochloride is a Src family kinases inhibitor with IC50s of 9 nM, 3 nM and 3 nM for Src, Lck and Lyn, respectively[1][2].

IC50 & Target

IC50: 9 nM (Src), <3 nM (Lck), <3 nM (Lyn), 3 μM (Abl)[1]
In Vitro

"A419259 is a second-generation pyrrolopyrimidine that blocks proliferation and induces apoptosis in CML cell lines. It induces apoptosis in K-562 cells and also inhibits Meg-01 proliferation (IC50=0.1 μM)[1].
In the absence of IL-3, A-419259 strongly inhibits DAGM/Bcr-Abl cell proliferation (IC50=0.1-0.3 μM)[1].
A-419259 also inhibits overall SFK activity in CML cell lines and blocks Src kinase activation (IC50=0.1-0.3 μM)[1].
A 419259 trihydrochloride (1 μM; 16 h) inhibits endogenous SFK (c-Src and Lck) activity, thereby inhibiting Src-driven differentiation of mES cells toward primitive ectoderm-like cells[2].
A 419259 trihydrochloride (0.3, 1 μM; 5 days) has no effect on undifferentiated colony morphology of hES cells grown in mTeSR medium[2].

Kinase Assay
[1]

In vitro kinase assays are performed on His(6)-tagged Lck (residues 62-509) and full-length c-Abl purified from Sf-9 cells, and commercial sources of Lyn, Src and PKC. Lck, Lyn, Src and Abl activities are measured with an ELISA-based assay. Flat bottom 96-well ELISA plates are incubated with a 200 μg/mL solution of Poly(Glu,Tyr) 4 : 1 substrate in phosphate buffered saline (PBS) for 1 h at 37°C and then washed with PBS containing 0.1% Tween-20 (PBS-T). Inhibitor dilutions are added to the washed plates already containing the appropriate enzyme in kinase assay buffer (250 mM Mopso, pH 6.75, 10 mM MgCl2, 2 mM MnCl2, 2.5 mM DTT, 0.02% BSA, 2 mM Na3VO4, 5% DMSO, 5 μM ATP). After incubation at room temperature for 20 min, plates are washed three times with PBS-T and plate-bound phosphotyrosine is detected with an anti-phosphotyrosine-HRP antibody conjugate and subsequent color development with K-Blue reagents. All assays are optimized to use the least amount of enzyme necessary for a reproducible signal-to-noise ratio[1].

Cell Assay
[1]

K-562 cells are grown in RPMI 1640 supplemented with 10% fetal calf serum (FCS), and 50 g/mL Gentamycin. Meg-01 cells are cultured in Vitacell modified RPMI 1640 (ATCC), supplemented with 10% FCS and 50 μg/mL Gentamycin. The human GM-CSF-dependent myeloid leukemia cell line TF-1 is grown in RPMI 1640 supplemented with 10% FCS, 50 μg/mL Gentamycin, and 1 ng/mL of recombinant human GM-CSF. DAGM murine myeloid leukemia cells are cultured in RPMI 1640 supplemented with 10% FCS, 50 μg/mL Gentamycin, and 0.5 ng/mL recombinant IL-3. Concentrated stock solutions of PP2 (5 mM) and A-419259 (2 mM) are prepared in DMSO and stored at -20°C. Cellular proliferation is measured using the Live/Dead growth assay. This assay employs calcein-AM, a fluorogenic esterase substrate that is taken up by viable cells and hydrolyzed intracellularly, releasing a green fluorescent product. Briefly, 104 cells are plated per well in 96-well plates for each day of a 4-day time course. Various concentrations of PP2, A-419259 or vehicle control are added to the wells (five wells per concentration per day) and the plates are incubated at 37°C. At each time point, one plate is centrifuged at 1500 g for 10 min to pellet the cells. Cells are washed with phosphate buffered saline (PBS), and calcein-AM is added to each well to a final concentration of 1 μM. Plates are incubated in the dark at room temperature for 1 h. The plates are then read at 485/530 nm (excitation/emission) using a SpectraMax Gemini XS fluorescent plate reader and data are analysed with SoftMax Pro software[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
