    体外研究
    (In Vitro)

    PF-562271 (VS-6062) is shown to be a 30- to 120-nM inhibitor of CDK2/E, CDK5/p35, CDK1/B, and CDK3/E in recombinant enzyme assays, in cell-based assays evaluating the role of CDKs, a 48-hour exposure of 3.3 μM PF-562271 is required to alter cell cycle progression. PF-562271 is potent in an inducible cell-based assay measuring phospho-FAK with a IC50 of 5 nM[1].?
    ? PF-562271, a selective inhibitor of both FAK and proline-rich tyrosine kinase 2 (PYK2), a FAK-related family member, on cell growth and colony formation in Ewing sarcoma cell lines. Seven cell lines are treated for 5 days with PF-562271 across a range of concentrations using 2-fold serial dilutions. Treatment with PF-562271 impaires cell viability in all cell lines, with an average IC50 of 2.4 μM after 3 days of treatment. TC32 and A673 are the 2 most sensitive cell lines, with IC50 concentrations of 2.1 and 1.7 μM, respectively[2].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    体内研究
    (In Vivo)

    PF-562271 inhibits FAK phosphorylation in vivo in a dose-dependent fashion (calculated EC50 of 93 ng/mL, total) after p.o. administration to tumor-bearing mice[1]. Rats that receive PF-562271 demonstrate a decrease in tumor growth after 2 weeks of treatment with signs of bone healing as evidenced by the deposition of new bone (cortical and cancellous) at sites previously damaged by the tumor[3].

    Cell Assay
    [2]

    Ewing sarcoma cells are plated in 10-cm dishes, allowed to adhere for 24 hours, and then treated with PF-562271, PD0325901, or BMS-354825. ATP content is measured as a surrogate for cell number using the CellTiter-Glo Luminescent Cell Viability Assay. Luminescence readings are obtained using the FLUOstar Omega microplate reader. For experiments with small-molecule treatment, 1.25×103 Ewing sarcoma cells are seeded in each well and treated with a range of concentrations. IC50 values are calculated from ATP measurements obtained after 3 days of treatment using log-transformed, normalized data in GraphPad Prism 5.0. Cell lines are also treated with compound in 6-cm dishes, trypsinized, and counted by light microscopy using trypan blue exclusion. For experiments using shRNA-transduced cells, 1.25×103 cells are seeded per well into 384-well plates on day 3 posttransduction. ATP content is measured on days 3, 6, and 8 posttransduction[2].

    Animal Administration
    [1][3]

    Mice[1]
    Athymic female mice (CD-1 Nu/Nu, ~20 grams) are used for all in vivo studies. Exponentially growing cells are trypsinized and resuspended in sterile PBS and inoculated s.c. (1×106 cells per mouse in 200 μL) into the right flank of mice. Animals bearing tumors of 150 mm3 in size are divided into groups receiving either vehicle (5% Gelucire) or PF-562,271 (diluted in vehicle), and dosed by p.o. gavage. Animal body weight and tumor measurements are obtained every 2 d. Tumor volume (mm3) is measured with Vernier calipers and calculated using the formula: length (mm)×width (mm)×width (mm)×0.5. Percent growth inhibition. For all tumor growth inhibition experiments, 8 to 10 mice per dose group are used. A Student's t test is used to determine the P value.
    Rats[3]
    Nude (Crl:NIH-rnu) female rats are used. PF-562271 is formulated for oral dosing using 0.5% methyl-cellulose. On the first day of dosing, rats receive a single dose of PF-562271 (10 mg/kg) by oral gavage. Based on the exposure levels at 1 hour after dosing, the dose is reduced to 5 mg/kg. From the second day onward, rats are dosed daily with 5 mg/kg by oral gavage for 28 days. Dosing is initiated 2 weeks after tumor inoculation and only after the presence of tumors is confirmed by radiography. The presence of the tested compound in serum is confirmed during the course of the study.

    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.
