| In vitro |
In vitro, GSK126 most potently inhibits H3K27me3, followed by H3K27me2 in both EZH2 wild-type and mutant DLBCL cell lines. GSK126 also effectively inhibits the proliferation of EZH2 mutant DLBCL cell lines, and induces transcriptional activation of EZH2 target genes in sensitive cell lines. [1] In A687V EZH2-mutant cells, GSK126 treatment results in a global decrease in H3K27me3, robust gene activation, caspase activation, and decreased proliferation. [2] In parental H2087 cells, GSK126 inhibits the expression of VEGF-A and phosphorylated Ser(473)-AKT, and thus causes the inhibition of cell proliferation, migration and metastasis. [3] |

| In vivo | In mice bearing KARPAS-422 and Pfeiffer xenografts, GSK126 (150 mg/kg/d, i.p.) decreases global H3K27me3, increases gene expression, and thus causes marked tumour regression. [1] |

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.
