When tested in this orthotopic xenograft bladder cancer model, NVP-BGJ398 (10 and 30 mg/kg) induced tumor growth inhibition and stasis after oral administration for 12 consecutive days. The monophosphate salt of 1h was orally administered to juvenile, immunocompromised, female Rowett rats for 20 consecutive days (20 administrations) at the doses of 5, 10, and 15 mg/kg/qd (free base equivalents). Nearly complete tumor stasis was achieved at the lowest dose while no overt toxicity was observed. The doses of 10 and 15 mg/kg provided tumor regression which was accompanied by a dose-dependent decrease of body weight. NVP-BGJ398 (30 mg/kg, p.o.) significantly delayed the growth of FGFR2-mutated endometrial cancer xenograft tumors. NVP-BGJ398 had no in vivo inhibitory effects in the long-term study using the FGFR2 wild-type endometrial cancer cell line SNGM |
細胞實驗: |
Murine BaF3 cell lines, whose proliferation and survival has been rendered IL-3-independent by stable transduction with tyrosine kinases activated either by mutation or fusion with a dimerizing partner, were cultured in RPMI-1640 media supplemented with 10% FBS, 4.5 g/L glucose, 1.5 g/L sodium bicarbonate, and Pen/Strep. Cells were passaged twice weekly. Compound-mediated inhibition of BaF3 cell proliferation and viability was assessed using a Luciferase bioluminescent assay. Exponentially growing BaF3 or BaF3 Tel-TK cells were seeded into 384-well plates (4250 cells/well) at 50 μL/well using a μFill liquid dispenser in fresh medium. NVP-BGJ398 was serially diluted in DMSO and arrayed in a polypropylene 384-well plate. Then 50 nL of compound was transferred into the plates containing the cells by using the pintool transfer device, and the plates incubated at 37 ℃ (5% CO2) for 48 h. Then 25 μL of Bright-Glo were added, and luminescence was quantified using an Analyst-GT. Custom curve-fitting software was used |
動物實驗: |
We used FGFR2-mutated MFE296, AN3CA, and FGFR2 wild-type SNGM and HEC1A endometrial cancer cells, which spontaneously formed xenografts in athymic mice for our in vivo studies. Mice were maintained and handled under aseptic conditions, and animals were allowed access to food and water ad libitum. Female athymic mice (20.0–30.0 g) aged 4 to 6 weeks from an outbred strain (CD1 nu/nu) were injected subcutaneously (2 × 10^7 cells per mouse) in the flank. AN3CA cells were suspended in Matrigel and DMEM (volume 1:1). A period of 7 days elapsed to allow the formation of tumor nodules (mean xenograft volume = 105 ± 5.6 mm^3). Mice were then stratified into treatment groups with one tumor per mouse on the basis of their weight and tumor volume at the start of the experiment, such that the starting weight and tumor volume in each group were uniform. Mice (10/group) were treated via oral gavage of (i) vehicle control (5 mmol/L sodium citrate and 1 μL 6N HCL/mL), (ii) NVP-BGJ398 30 mg/kg (6 mg in 0.5 mL PEG300 and 0.5 mL |
