产品描述 | SGC0946 is a highly effective and specific DOT1L methyltransferase inhibitor (IC50: 0.3 nM); selectively kill mixed lineage leukemia cells. |
靶点活性 | DOT1L:0.3 nM |
体内活性 | SGC 0946可使A431细胞(IC50:2.6 nM)和MCF10A细胞(IC50:8.8 nM)中H3K79二甲基化显著降低,并可有效并选择性地杀死含MLL易位的细胞。与其类似物EPZ004777相比,SGC 0946对DOT1L更有效,从而用于癌症治疗的研究中。SGC 0946比其他组蛋白甲基转移酶/HMTs选择性高100倍。 |
激酶实验 | Determination of Inhibitor IC50 Values: EPZ004777 is serially diluted 3-fold in DMSO for a total of ten concentrations, beginning at 1 mM. A 1 μL aliquot of each inhibitor dilution is plated in a 384-well microtiter plate. The 100% inhibition control consisted of 2.5 mM ?nal concentration of the product inhibitor S-adenosyl-L-homocysteine, (SAH). Compound is incubated for 30 min with 40 ml per well of 0.25 nM DOT1L(1-416) in assay buffer (20 mM TRIS [pH 8.0] 10 mM NaCl, 0.002% Tween 20, 0.005% Bovine Skin Gelatin, 100 mM KCl, and 0.5 mM DTT). 10 ml per well of substrate mix comprising assay buffer with 200 nM 3H-SAM (American Radiolabeled Chemicals: 80 Ci/mmol), 600 nM unlabeled SAM, and 20 nM nucleosomes are added to initiate the reaction (both substrates are present in the ?nal reaction mixture at their respective KM values). Reactions are incubated for 120 min and quenched with 10 ml per well of 800 mM SAM. Incorporation of radioactivity into nucleosome substrate is measured in a ?ashplate. IC50 values for enzymes in the histone methyltransferase panel are determined under similar balanced assay conditions with both SAM and protein/peptide substrate present at concentrations equal to their respective KM values. |
