CPI-203 (RO6870810, JQ-2, TEN010, RG6146) is a novel, selective, cell permeable and orally bioavailable BET bromodomain inhibitor with anticancer activity. It inhibits BRD4 with an IC50 of 37 nM in a BRD4 α-screen assay. CPI 203 shows potent in vitro antiproliferative activity and high in vivo antitumor efficacy. CPI203 can enhance the antiproliferative effects of rapamycin on human neuroendocrine tumors. CPI203 can downregulate Myc expression, causes G1 cell cycle arrest and attenuate cell proliferation in human pancreatic neuroendocrine tumors. CPI203 arrests the growth of T cell acute lymphoblastic leukemia cells in vitro (EC50 = 91.2 nM).
ln Vitro |
CPI-203 inhibits BRD4 in vitro and in cells, but does not influence BRD4 kinase activity in vitro [1]. CPI -203 had cytostatic effects in all 9 MCL cell lines with GI50 ranging from 0.06 to 0.71 μM and had little cytotoxicity against normal PBMC from healthy volunteers. In addition, CPI -203 can effectively initiate the cell death pathway in MCL cells [2].

ln Vivo |
Lenalidomide and CPI-203 (2.5 mg/kg, i.p.) together improved the anticancer effects of each individual drug by causing apoptosis in nREC-1 tumor-bearing mice and mutating MYC and IRF4 expression. [2].

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (6.25 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (6.25 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More
Solubility in Formulation 3: ≥ 2.5 mg/mL (6.25 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
