| Description: | The ability of the disclosed compounds to inhibit HIF-2α was measured by determining VEGF expression in 786-O cells. About 7500 786-O cells were seeded into each well of a 96-well, white, clear bottom plate (07-200-566, Fisher Scientific) with 200 ul growth medium. Four hours later, compounds were dispensed into wells by Tecan D300e digital dispenser with starting concentration of 10 uM and log of dilution down to 1 nM as final concentration. Each concentration of treatment was performed in duplicate. About 20 hours later, medium was removed and fresh medium was added, followed by compounds treatment as described above. 24 hours later, cell culture medium was collected to determine VEGF concentration using an ELISA kit (R&D systems, cat #DVE00) following the manufacturer's instruction.The EC50 is calculated by GraphPad Prism using the dose-response-inhibition (four parameter) equation. The plate with cells was then subjected to CellTiter-Glo luminescence cell viability assay (Promega) to determine the effect of these compounds on cell numbers after the above treatment. |
