| | Inhibition of FGFR2-Dependent Cell Growth |
| Description: | The cell-based effects of FGFR inhibitors were determined by measuring inhibition of FGFR-dependent cell line growth. The cell lines SNU-16 was used for these assays. SNU-16 cells were seeded in a 96-well plate at 5,000 cells per well in RPMI 1640 high glucose medium with 10% fetal bovine serum (FBS. Cells were incubated at 37° C. for 24 hrs. in 5% CO2. Compound dilutions were added to cells starting at a concentration of 30 uM and decreasing in tripling dilutions. The final DMSO concentration was 0.1%. The concentration range was adjusted as needed for compounds of different potencies. The cells treated with compounds were incubated for 72 hrs. at 37° C. in 5% CO2. At the end of the 72 hour incubation period, cell viability was determined using the Cell-titer Glo Luminescence assay from Promega. Percent inhibition of cell growth was calculated as a percentage of untreated cell viability. The percent inhibition was plotted as a function of log compound concentration. The IC50 was then calculated for each compound using Prism software from GraphPad. |
