Assay: Western Blot/CellTiterGlo
DC50:  1.6 nM
Assay description: BCL-XL Degradation Assay
Cell Culture
Human T lymphoblast MOLT-4 were cultured in RPMI 1640 media, supplemented with 10%FBS. All cell lines were maintained at 37 °C in an atmosphere of 5%CO2.
Protein extraction and Western blotting
Whole cell lysates were prepared using cell Lysis Buffer supplemented with Protease inhibitor, phosphatase inhibitor and PMSF solution. The concentration of protein was quantified using a Pierce Bicinchoninic Acid (BCA) Protein Concentration Kit. Equal amounts of protein were loaded for PAGE and transfer samples onto a PVDF membrane using Bio-Rad's Trans blot. The blots were incubated with a primary antibody followed by HRP conjugated to an appropriate secondary antibody.
Cell viability assay
Cell viability was measured using a CellTiter-Glo Assay kit according to the manufacturer's protocol. MOLT-4 were seeded into 384-well plates and treated with various increasing doses of compound for 72 hours. Cell plates were taken from the incubator and equilibrated withThe plates were read on an Envision 2104 Multi-plate reader using a luminescence detector.
Representative degradation activity and cell viability from exemplary compounds is presented in Table 8.

Assay: Nano-Glo HiBiT Lytic
DC50:  9.91 nM
Assay description: 1) Cell culture. The culture medium for cell culture is DMEM medium containing inactivated 10% fetal bovine serum, 100U/ml penicillin and 100μg/ml streptomycin. HEK293-IRAK4-Hibit cells are cultured in an incubator at 37°C and 5% CO2 . When the cell confluence reaches 80-90%, the cells are subcultured. Cells in the logarithmic growth phase are used for plating. HEK293-IRAK4-Hibit cells are plated in a 96-well plate with 100μL culture medium, 20,000-30,000 cells per well, and cultured overnight.

2) Compound dilution. The compound was dissolved in DMSO to a concentration of 10 mM. The compound was then graded diluted in DMSO to concentrations of 2000 μM, 500 μM, 125 μM, 32.25 μM, 7.81 μM, 1.95 μM, 0.49 μM, 0.12 μM and 0.031 μM.

3) Adding drugs. Take 1 μL of the diluted compound and add it to 1 ml of complete medium. After mixing, take 100 μL and add it to a 96-well plate. The working concentrations reach 1000 nM, 250 nM, 62.5 nM, 15.6 nM, 3.91 nM, 0.98 nM, 0.24 nM, 0.061 nM, 0.015 nM and 0 nM.

4) Activity detection. The drug treatment was performed for 24 hours and the detection method was based on that of Promega HiBiT Lytic Detection System Instructions.

5) DC50 calculation. Relative IRAK4 (%) = (Lumninence experiment - Lumninence blank) / (Lumninence DMSO - Lumninence blank), calculated by fitting based on log (inhibitor) vs. response -- Variable slope (four parameters).

The experimental results are shown in Table 1, showing the data of the degradation of IRAK4 protein by the compounds of the present invention.

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.
