化合物TG003 T1901

Product Introduction
Bioactivity


英文名: (E/Z)-TG003

描述: (E/Z)-TG003 是一种有效的 ATP 竞争性 Cdc2 样激酶 (Clk) 抑制剂，抑制 Clk1 和 Clk4 的 IC50值分别为 20 和 15 nM。它是 (Z)-TG003 和 (E)-TG003的消旋体。

细胞实验: 2 × 105 HeLa cells or 1.5 × 105 COS-7 cells resuspended in 2 mL of medium are plated on 6-well dishes, and 2 μL of 10 mM TG003 dissolved in Me2SO (final concentration at 10 μM), or 2 μL of Me2SO, is added to some wells. Cells are trypsinized, and the density is counted every 24 h for 3 days. Cells are then fixed with 1 mL of ice-cold 70% ethanol, washed with PBS, incubated in 1 ml of PBS containing 1 μg/mL DNase-free RNase A and 50 μg/mL propidium iodide for 20 min at 37 °C, and proceeded to cell cycle analysis by FACSCalibur.(Only for Reference)

激酶实验: In Vitro Kinase Assay : Kinase activity of Clks and SRPKs is assayed in a reaction mixture, containing 200 mM Tris-HCl (pH 7.5), 12.5 mM MgCl2, 8 mM dithiothreitol, 4 mM EGTA, 1–20 μM ATP, 1 μCi of [γ-32P]ATP, 1 μg of synthetic peptide of SF2/ASF RS domain (NH2-RSPSYGRSRSRSRSRSRSRSRSNSRSRSY-OH), and 0.1–1 μg of purified kinases in a final volume of 40 μL. cAMP-dependent protein kinase activity is assayed in a reaction mixture containing 80 mM Tris-HCl (pH 7.5), 12.5 mM MgCl2, 8 mM dithiothreitol, 4 mM EGTA, 10 μM ATP, 1 μCi of [γ-32P]ATP, 5 μg of histone H1, and 1 μg of catalytic subunit of rat cAMP-dependent protein kinase purified. Protein kinase C activity is assayed in a reaction mixture containing 200 mM Tris-HCl (pH 7.5), 12.5 mM MgCl2, 1 mM CaCl2, 80 μg/mL phosphatidylserine, 8 μg/mL diolein, 10 μM ATP, 1 μCi of [γ-32P]ATP, 5 μg of histone H1, and 2 μL of partially purified rat protein kinase C. The final concentration of Me2SO is adjusted to 1% regardless of inhibitor concentration. The reaction mixture is incubated at 30 or 25 °C for mammalian or Xenopus recombinant proteins, respectively, for 10 min, and a half-portion is spotted on P81 phosphocellulose membrane. The kinase assay conditions, including the incubation period and concentration of kinases and substrates, are optimized to maintain the linearity during incubation. The membrane is washed with 5% phosphoric acid solution (SF2/ASF RS domain) or 5% trichloroacetic solution (histone H1) at least over 15 min. The radioactivity is measured using a liquid scintillation counter. The net radioactivity is deduced by subtracting the background count from the reaction mixture without kinase, and the data are expressed as the percentage to the control sample containing the solvent.
