In Vitro

Molibresib (I-BET 762) shows the highest affinity interaction with BET. Molibresib binds to the tandem bromodomains of BET with high affinity (dissociation constant K_d of 50.5-61.3 nM). Molibresib displaces, with high efficacy (half-maximum inhibitory concentration IC₅₀ of 32.5-42.5 nM), a tetra-acetylated H4 peptide that had been pre-bound to tandem bromodomains of BET^[1]. Molibresib has high affinity for BD1/BD2 domain of BRD2/3/4 proteins. Molibresib treatment leads to a reduction in the recruitment of all three proteins to chromatin^[2]. Molibresib inhibits OPM-2 cell proliferation with IC₅₀ of 60.15 nM^[3].

* Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (5.90 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Protocol 2

Add each solvent one by one: 5% DMSO 40% PEG300 5% Tween-80 50% Saline
Solubility: ≥ 2.5 mg/mL (5.90 mM); Clear solution
Protocol 3

Add each solvent one by one: 5% DMSO 95% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (5.90 mM); Clear solution
Protocol 4

Add each solvent one by one: 1% DMSO 99% Saline
Solubility: ≥ 0.5 mg/mL (1.18 mM); Clear solution
