MS1262
MS1262 is a blood-brain barrier-permeable, selective inhibitor of histone methyltransferases G9a (EHMT2) and GLP (EHMT1), with an IC50 of 19 nM and a Kd of 74 nM against G9a, and an IC50 of 6 nM and a Kd of 19 nM against GLP. MS1262 reduces the dimethylation level of histone H3 lysine 9 and decreases the size of Aβ plaques. MS1262 restores hippocampal long-term potentiation (LTP) and miniature excitatory postsynaptic current (sEPSC) frequency, ameliorates spatial memory deficits, and reverses anxiety-like and depression-like behaviors in AD model mice. MS1262 reverses the expression/phosphorylation levels of early AD biomarkers, providing support for stage-specific diagnosis of AD. MS1262 reduces the risk of thrombus rupture. MS1262 can be used in research related to Alzheimer's disease, colorectal cancer, and triple-negative breast cancer.

Activité biologique
MS1262 is a highly potent inhibitor of purified G9a and GLP proteins, with IC50 values of 19 nM and 6 nM, respectively, and Kd values of 74 nM and 19 nM, respectively[1].
MS1262 (1 µM) exhibits excellent selectivity for G9a and GLP, with no significant inhibition of 21 other methyltransferases at 1 µM[1].
MS1262 (5-5000 nM; 48 h) reduces H3K9me2 levels in K562 cells in a concentration-dependent manner following 48 hours of treatment[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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.
