Assay description: PROTAC compounds disclosed in this invention degrade ERα in T-47D cells. T-47D cells were cultured in PRMI-1640 medium supplemented with 10% FBS at 37°C and 5% CO2 until they entered the logarithmic growth phase. T-47D cells were seeded at a density of 3×105 cells/well in 6-well plates and incubated at 37°C and 5% CO2 for 24 hours. After the cells adhered, 1 μL of compound solution in dimethyl sulfoxide (DMSO) (final concentration 0.15-1000 nM) was added and incubated for another 4 hours at 37°C and 5% CO2. After 4 hours, the medium was discarded, and each well was washed once with 1 mL of pre-chilled 1× DPBS. The cells were then lysed with 50 μL of RIPA lysis buffer and 1× protease inhibitor cocktail, incubated on ice for 20 minutes, and centrifuged at 14,000g at 4°C for 30 minutes. The supernatant was carefully removed and analyzed for ERα protein levels by immunoblotting.

Assay description: PROTAC compounds disclosed in this invention degrade ERα in T-47D cells. T-47D cells were cultured in PRMI-1640 medium supplemented with 10% FBS at 37°C and 5% CO2 until they entered the logarithmic growth phase. T-47D cells were seeded at a density of 3×105 cells/well in 6-well plates and incubated at 37°C and 5% CO2 for 24 hours. After the cells adhered, 1 μL of compound solution in dimethyl sulfoxide (DMSO) (final concentration 0.15-1000 nM) was added and incubated for another 4 hours at 37°C and 5% CO2. After 4 hours, the medium was discarded, and each well was washed once with 1 mL of pre-chilled 1× DPBS. The cells were then lysed with 50 μL of RIPA lysis buffer and 1× protease inhibitor cocktail, incubated on ice for 20 minutes, and centrifuged at 14,000g at 4°C for 30 minutes. The supernatant was carefully removed and analyzed for ERα protein levels by immunoblotting.

Assay description: PROTAC compounds disclosed in this invention degrade ERα in T-47D cells. T-47D cells were cultured in PRMI-1640 medium supplemented with 10% FBS at 37°C and 5% CO2 until they entered the logarithmic growth phase. T-47D cells were seeded at a density of 3×105 cells/well in 6-well plates and incubated at 37°C and 5% CO2 for 24 hours. After the cells adhered, 1 μL of compound solution in dimethyl sulfoxide (DMSO) (final concentration 0.15-1000 nM) was added and incubated for another 4 hours at 37°C and 5% CO2. After 4 hours, the medium was discarded, and each well was washed once with 1 mL of pre-chilled 1× DPBS. The cells were then lysed with 50 μL of RIPA lysis buffer and 1× protease inhibitor cocktail, incubated on ice for 20 minutes, and centrifuged at 14,000g at 4°C for 30 minutes. The supernatant was carefully removed and analyzed for ERα protein levels by immunoblotting.
