Assay description: The IKZF1 protein is one of the target protein substrates for the degradation of amine compounds. The IMiD activity of the compound is judged by the IKZF1 protein degradation experiment. The Mino cell samples degraded by the above BTK protein were detected, and the IKZF1 (CST, Cat. 14859S) protein was simultaneously detected by Western blot method. Calculate and obtain the degradation rate of the IKZF1 protein of the administration group relative to the vehicle group IKZF1 protein according to the following formula:

IKZF1% = (1 - (IKZF1 administration/β-actin)/(IKZF1 vehicle/β-actin)) × 100%

IKZF1 administration is the expression level of IKZF1 in Mino cells at different doses of the compound, and IKZF1 vehicle is the expression level of IKZF1 in Mino cells in the control group. The maximum concentration of the compound in this experimental system is 1000 nM. Dmax is the maximum degradation value in the experimental concentration system, and use Graphpad 5.0 software according to the formula Y = 100/(1 + 10^((LogIC50 - X)*HillSlope)) to fit DC50 values.

Assay description: BTK degradation detection in Mino cells
Mino human mantle cell lymphoma cell line was purchased from ATCC and cultured in RPMI-1640 + 15% FBS + 1% double-antibody at 37°C in a 5% CO2 incubator. Cells were plated in 6-well plates at 5 × 105 cells/well. After plating, different concentrations of compounds were added and incubated at 37°C in a 5% CO2 incubator for 48 hours. After the incubation period, cells were harvested and lysed on ice for 15 minutes using RIPA lysis buffer (beyotime, Cat. P0013B). After centrifugation at 12,000 rpm and 4°C for 10 minutes, supernatant protein samples were collected and quantified using a BCA kit. The protein was diluted to 0.25 mg/mL and the expression of BTK and the internal reference β-actin was detected using the kit using an automated Western blot quantitative analyzer. BTK expression relative to the internal reference was calculated using Compass software, and DC50 values were calculated using Origen9.2 software according to formula (1). BTK administration refers to the BTK expression level in the different dose administration groups, and BTK vehicle refers to the BTK expression level in the vehicle control group.
BTK% = BTK administration/BTK vehicle × 100% Formula (1)

Assay description: Degradation of BTK in NAMALWA cells after 24 h treatment; BTK-targeting PROTACs, Compound 104 and Compound 106, possessed l2-atom linkers and showed nearly complete degradation of BTK at 1.0 mM in NAMALWA cells, a Burkitt's lymphoma-derived B-lymphocyte cell line (Table 5). Shortening the linker by a single atom (Compound 103) increased potency, based on the concentration of compound needed to degrade 50% of the total pool of BTK, denoted by DC50 (DC = degradation constant). However, shortening the linker length even further to 8- and 5-atoms (Compound 101 and Compound 100, respectively) resulted in an inability to degrade BTK. Without being bound by theory, these observations are consistent with the expected ternary complex model that plays a role in PROTAC action.; IC50 of ligand is 51.0 nM (WT BTK), 30.7 (C481S)

Assay description: Degradation of BTK in NAMALWA cells after 24 h treatment; BTK-targeting PROTACs, Compound 104 and Compound 106, possessed l2-atom linkers and showed nearly complete degradation of BTK at 1.0 mM in NAMALWA cells, a Burkitt's lymphoma-derived B-lymphocyte cell line (Table 5). Shortening the linker by a single atom (Compound 103) increased potency, based on the concentration of compound needed to degrade 50% of the total pool of BTK, denoted by DC50 (DC = degradation constant). However, shortening the linker length even further to 8- and 5-atoms (Compound 101 and Compound 100, respectively) resulted in an inability to degrade BTK. Without being bound by theory, these observations are consistent with the expected ternary complex model that plays a role in PROTAC action.; IC50 of ligand is 51.0 nM (WT BTK), 30.7 (C481S)
