Assay: Nano-Glo HiBiT Lytic
DC50:  2.7 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: THP1-HIBiT-IRAK4 cells were cultured in RPMI1640 medium supplemented with 10% fetal bovine serum (FBS) and 1% penicillin-streptomycin (PS) (37°C, 5% CO2). THP1-HIBiT-IRAK4 cells were seeded in a 384-well plate at 5000 cells/40 μL/well. Compound solutions of different concentrations were added to the wells at 40 nL/well and incubated at 37°C, 5% CO2 for 24 h. HiBit cleavage detection reagent was added to the wells, the wells were incubated at room temperature for 30 min, and then the luminescence value was read on Envision.
Degradation rate (%) = (luminescence value of compound well/average luminescence value of DMSO well) × 100
XLFIT software was used to obtain the DC50 (half maximal degradation concentration) of the compound using the following nonlinear fitting formula:
Y = bottom + (top - bottom) / (1 + 10^((LogDC50 -X) × Hill slope))
X: log value of compound concentration;

Assay description: THP1-HIBiT-IRAK4 cells were cultured in RPMI1640 medium supplemented with 10% fetal bovine serum (FBS) and 1% penicillin-streptomycin (PS) (37°C, 5% CO2). THP1-HIBiT-IRAK4 cells were seeded in a 384-well plate at 5000 cells/40 μL/well. Compound solutions of different concentrations were added to the wells at 40 nL/well and incubated at 37°C, 5% CO2 for 24 h. HiBit cleavage detection reagent was added to the wells, the wells were incubated at room temperature for 30 min, and then the luminescence value was read on Envision.
Degradation rate (%) = (luminescence value of compound well/average luminescence value of DMSO well) × 100
XLFIT software was used to obtain the DC50 (half maximal degradation concentration) of the compound using the following nonlinear fitting formula:
Y = bottom + (top - bottom) / (1 + 10^((LogDC50 -X) × Hill slope))
X: log value of compound concentration;
Y: Degradation rate
The results of IRAK4 protein degradation DC50 values are shown in Table 1.

Assay: HiBiT
DC50:  13.91 nM
Assay description: THP1-HIBiT-IRAK4 cells were cultured in RPMI1640 medium supplemented with 10% fetal bovine serum (FBS) and 1% penicillin-streptomycin (PS) (37°C, 5% CO2). THP1-HIBiT-IRAK4 cells were seeded in a 384-well plate at 5000 cells/40 μL/well. Compound solutions of different concentrations were added to the wells at 40 nL/well and incubated at 37°C, 5% CO2 for 24 h. HiBit cleavage detection reagent was added to the wells, the wells were incubated at room temperature for 30 min, and then the luminescence value was read on Envision.
Degradation rate (%) = (luminescence value of compound well/average luminescence value of DMSO well) × 100
XLFIT software was used to obtain the DC50 (half maximal degradation concentration) of the compound using the following nonlinear fitting formula:
Y = bottom + (top - bottom) / (1 + 10^((LogDC50 -X) × Hill slope))
X: log value of compound concentration;
Y: Degradation rate
The results of IRAK4 protein degradation DC50 values are shown in Table 1.
