| Description: | RIPK1 protein was over-expressed in HEK293 cell line, to which lysis buffer (50 mM Tris-Cl [pH 8.0], 150 mM NaCl, 1 mM EDTA, 1% NP-40, 0.4 mM phenylmethylsulfonyl fluoride (PMSF)) was added for cell lysis. Centrifugation was performed at 13,000 rpm for 10 minutes to separate the supernatant. RIPK1 monoclonal antibody (610459, BD Bioscience) and A/G agarose beads (sc-2003, Santa Cruz Biotechnology) were added thereto, followed by immuno-precipitation in a 4° C. rotator for 12 hours.The compounds of examples of the invention were diluted at the different concentrations of 10 μM 0.05 μM (10, 5, 1, 0.5, 0.1, 0.05 uM) and mixed with the immuno-precipitated RIPK1 enzyme, followed by reaction in a 24° C. constant-temperature water bath for 15 minutes. Additional reaction was induced for 30 minutes at 30° C. after 100 μM of ATP and 10 μCi[32P] γ-ATP were added thereto. The reaction mixture was washed with buffer once, to which protein loading buffer was added, followed by heating at 100° C. for 3 minutes. The reaction mixture was then loaded on 8% SDS-PAGE gel. Radioactive image of the phosphorylated RIPK1 was detected with FLA-7000 (GE healthcare). |
