Product Introduction

Bioactivity
Description
I-BET151 (GSK1210151A) (GSK1210151A) is a specific BET inhibitor for BRD2/3/4 (IC50: 0.5/0.25/0.79 μM, in cell-free assays).
Targets&IC50
BRD3:0.25 μM, BRD4:0.79 μM, BRD2:0.5 μM
In vitro
I-BET151 administration (30 mg/kg/day) in mice significantly inhibits the growth of MLL-AF9 murine and MLL-AF4 human leukemia tumors and notably prolongs lifespan.
In vivo
When interacting with HL60 nuclear extracts, I-BET151 at concentrations of 0.5 or 5 μM inhibits the binding of BETs (BRD2/3/4/9) to acetylated histone peptides without affecting 23 other bromodomain proteins. This compound demonstrates potent inhibitory effects on cell lines with various MLL fusions, such as MV4;11, RS4;11, MOLM13, and NOMO1 cells (IC50: 15-192 nM). I-BET151 shows broad selectivity in inhibiting multiple protein types, including COX-2, P450, Aurora B, GSK3β, PI3K-γ, GPCR, ion channels, and transporters. Similar to I-BET762 (GSK525762A), I-BET151 possesses a high binding affinity for BRD2/3/4 (Kd: 0.02-0.1 μM) and significantly inhibits the production of the IL-6 cytokine in response to lipopolysaccharide stimulation in human peripheral blood mononuclear cells, whole blood, and rat WB (IC50: 0.16/1.26/1.26 μM).
Kinase Assay
Fluorescence anisotropy (FP) ligand displacement assay: All components are dissolved in buffer of composition 50 mM HEPES pH 7.4, 150 mM NaCl and 0.5 mM CHAPS with final concentrations of BRD 2/3/4 75 nM, fluorescent ligand 5 nM. 10 μL of this reaction mixture is added using a micro multidrop to wells containing 100 nL of various concentrations of I-BET151 or DMSO vehicle (1% final) in Greiner 384 well Black low volume microtitre plate and equilibrated in the dark for 60 minutes at room temperature. Fluorescence anisotropy is read in Envision (lex = 485 nm, lEM = 530 nm; Dichroic = 505 nM).
Cell Research
Cells are exposed to various concentrations of I-BET151 for 24 or 72 hours in 384-well or 96-well plates. For cell growth inhibition assays, plates are added with CellTiter-Glo reagent using a volume equivalent to the cell culture volume in the wells, shaken for approximately 2 minutes and chemiluminescent signal is read on the Analyst GT or EnVision Plate Reader. For cell proliferation assays, CellTiter-Aqueous One is added to each well and plates are incubated for 4 hours at 37 °C. Absorbance is read at 490 nm on a SpectraMax Gemini reader (Only for Reference)

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
