MS147
Based on 1 Customer Validation
MS147 is a VHL-based PROTAC degrader of BMI1 and RING1B (polycomb repressive complex 1 core components). MS147 directly binds EED and VHL E3 ligase, recruiting the ligase to the EED-BMI1/RING1B complex to induce time-dependent, ubiquitination-mediated degradation of BMI1 and RING1B. MS147 reduces histone H2A Lys119 mono-ubiquitination without altering histone H3 Lys27 tri-methylation and inhibits cancer cells proliferation. MS147 can be used for the research of cancer, such as chronic myelogenous leukemia and b-cell lymphoma.
(Pink: BMI1 and RING1B ligand (HY-183634); Blue: VHL ligand (HY-125845); Black: linker).

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (2.46 mM); Clear solution
