Biological Activity

In vitro: AS1517499 inhibit IL-4-induced Th2 differentiation of mouse spleen T cells, but has no influence on Th1 differentiation induced by IL-12. AS1517499 is able to prevent the IL-4-activated STAT6-mediated increase of the clonogenic potential of primary PCa cells. At a dose of 300 nM, AS1517499 decreases the clonogenic potential of primary basal PCa cells.

In vivo: In vivo treatment with AS1517499 ameliorates the antigen-induced bronchial smooth muscle (BSM) hyperresponsiveness by inhibiting the RhoA up-regulation in BSMs and, at least in part, by reducing the IL-13 production in the airways in mice. AS1517499 reduces preventive effects of apoptotic cell instillation on bleomycin-induced lung fibrosis by suppressing PPARγ.

Protocol
Cell Experiment
Cell lines Normal human BSM cells
Preparation method Cells are maintained in SmBM medium supplemented with 5% fetal bovine serum, 0.5 ng/ml human epidermal growth factor (hEGF), 5 mg/ml insulin, 2 ng/ml human fibroblast growth factor-basic (hFGF-b), 50 mg/ml gentamicin, and 50 ng/ml amphotericin B. Cells are maintained at 37℃ in a humidified atmosphere (5% CO2), fed every 48 to 72 hours, and passaged when cells reached 90 to 95% confluence. Then the hBSMCs (passages 7-9) are seeded in 6-well plates and 8-well chamber slides at a density of 3,500 cells/cm2 and, when 80 to 85% confluence is observed, cells are cultured without serum for 24 hours before addition of recombinant human IL-13. AS1517499, or its vehicle (0.3% DMSO) is treated 30 minutes before the addition of IL-13 (100 ng/ml). In some experiments, AS1517499 is treated 0 (co-incubation), 3, or 12 hours after the addition of IL-13. In another series of experiments, a selective Rho-kinase inhibitor Y-27632 or its vehicle (0.3% DMSO) is also applied 15 minutes before the IL-13 application. At the indicated time after the IL-13 treatment, cells are washed with PBS, immediately collected, and disrupted with 1×SDS sample buffer (250 μl/well), and used for Western blot analyses.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
