Biological Activity

Description

Valemetostat (DS-3201, DS-3201b) is a selective EZH1/2 dual inhibitor.

Targets

EZH1 ^[1]

EZH2 ^[1]

In vitro
In vitro	Valemetostat significantly reducs ATL cell viability compared with the others. Valemetostat significantly reactivates the expression of the highly H3K27me3-accumulated EZH1/2 target genes in an ex vivo culture of primary ATL cells. Valemetostat shows superior anti-growth effects compared with EZH2-selective inhibitor in malignant lymphoma cell lines.^[1].

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid 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 master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
