Takinib 是一种TAK1自磷酸化的抑制剂,也是恶性疟原虫蛋白激酶 9 抑制剂,在 ATP 结合口袋内非竞争性结合。它诱导 TNF-α 刺激的细胞凋亡,可研究类风湿关节炎和转移性乳腺癌。
产品描述
Takinib is a specific and effective TAK1 inhibitor(IC50= 9.5 nM).
体外活性
Takinib reduces phosphorylation significantly but does not influence total protein levels. Takinib inhibits phosphorylation of IKK, MAPK 8/9, and c-Jun in a dose-dependent manner. Takinib(10 mM) shows significant inhibitory activity (<10% enzyme activity after exposure) on six serine/threonine kinases, including TAK1, IRAK4, IRAK1, GCK, CLK2, and MINK1.
激酶实验
TAK1-TAB1 (50 ng/well) is incubated with 5 μM ATP containing radiolabeled [32P]-ATP in the presence of 300 mM substrate peptide (RLGRDKYKTLRQIRQ) in a final volume of 40 μL in the presence of buffer (containing 50 mM Tris pH 7.5, 0.1 mM EGTA, 0.1% β-Mercaptoethanol, 10 mM magnesium acetate, 0.5 mM MnCl) and indicated compounds. The reaction is let go for 10 min and stopped with 10 μL concentrated H3PO4.
细胞实验
MDA-MB-231 cells (1,000 cells/well) are seeded in a 96-well plate with 10% FBS, 5% Pen/Strep, 4 g/L glucose DMEM medium. After 24h, cells are serum starved with 1% FBS, 5% Pen/Strep, 4 g/L glucose DMEM medium for 4h. Cells are treated with titrations of Takinib in the presence or absence of 30 ng/mL TNFα. Plates at 0 h and 24 h following treatment are frozen at -80°C after removal of media. After 24 h, 100 μL ddH2O is added to each well and plates are refrozen. 1 μL from Hoechst stock [1 mg/mL in 1:4 DMSO/H2O] is dissolved in 1 mL of TNE buffer (10 mM Tris, 2 M NaCl, 1 mM Na2EDTA) and 100 μL of this solution is added to each well. The fluorescence is determined at 355/460 nm.
