Binding
Binding Assay: Briefly, 20 nL of compounds were transferred to the 384-well plate by Echo® 550 liquid handler (Labcyte, USA), then 5 μL of BRD4(BD1) (Reaction Biology Company, RD-11-157) solution or the assay buffer was added to each well. After incubating at RT for 15 min, 5 μL of the biotinylated H4 derived acetylated peptide (synthesized by GL Biochem (Shanghai) Ltd) and 10 μL of the detection solution (Cisbio Assay) were added to each well. After incubating for 1 h at RT, the HTRF signal was measure at 615 nm and 665 nm using the EnVision Multilabel Plate Reader (PerkinElmer, USA). Results were analyzed with a two-wavelength signal ratio: intensity (665 nm)/intensity (615 nm). The inhibition percentage in the presence of the compound was calculated according to the equation, Percent inhibition=(Max−Signal)/(Max−Min)*100%. Fit the data in GraphPad Prism V5.0 software (San Diego, Calif.) to obtain IC50 values with nonlinear regression analysis using equation, Y=Bottom+(Top−Bottom)/(1+10{circumflex over ( )}((Log IC50−X)×HillSlope), where Y stands for inhibition percentage and X stands for compound concentration.
