MS152
Based on 1 Customer Validation
MS152 is an orally active, blood-brain barrier penetrant inhibitor of EHMT2/G9a and EHMT1/GLP, with IC50s of 76 nM and 126 nM, repsectively. MS152 reduces H3K9me2 levels and reactivates maternally silenced Prader-Willi syndrome (PWS) genes. MS152 significantly improves perinatal lethality and growth retardation in mouse models, and is applicable to research related to Prader-Willi syndrome.

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 (6.49 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
