Product Description

Description: CPI-360 is a novel, highly potent, selective, and SAM-competitive inhibitor of enhancer of zeste homolog 2 (EZH2) with potential antitumor activity. It inhibits wt EZH2 and Y641N EZH2 with an IC50 of 0.5 nM and 2.5 nM, respectively. CPI-360 exhibits excellent antiproliferative activity and high in vivo antitumor efficacy. It functions on the basis of S-adenosyl-Lmethionine (SAM)-competition, inhibits EZH1 about 100-fold less and shows exquisite selectivity across a large panel of histone lysine and arginine, and DNA methyltransferases. CPI-360 potently reduced global H3K27me3 and H3K27me2 levels in a dose dependent manner. CPI-360 effectively suppressed heavy H3K27me3 incorporation in KARPAS-422 cells without affecting total histone turnover.

Biological Activity I Assay Protocols (From Reference)

ln Vitro

In vitro activity: In KARPAS-422 cells, CPI-360 potently reduces global H3K27me3 and H3K27me2 levels with EC50 of 56 nM and 65 nM, respectively. CPI-360 also causes time-dependent transcriptional changes, and affects the viability of Y641N mutant EZH2-containing KARPAS-422 cells. In addition, CPI-360 gradually arrests KARPAS-422 cells in the G1 cell cycle stage followed by the induction of apoptosis.

Kinase Assay: CPI-360 is a potent, selectiveEZH2inhibitor with IC50 of 0.5 nM and 2.5 nM nM for wt EZH2 and Y641N EZH2, respectively.

Cell Assay: CPI-360 functions on the basis of S-adenosyl-Lmethionine (SAM)-competition, inhibits EZH1 about 100-fold less and shows exquisite selectivity across a large panel of histone lysine and arginine, and DNA methyltransferases. CPI-360 potently reduced global H3K27me3 and H3K27me2 levels in a dosedependent manner. CPI-360 effectively suppressed heavy H3K27me3 incorporation in KARPAS-422 cells without affecting total histone turnover. CPI-360 treatment causes time-dependent transcriptional changes in germinal center B cell-like diffuse large B cell lymphoma.

ln Vivo

In mice bearing KARPAS-422 xenografts, CPI-360 (200 mg/kg, s.c.) reduces tumor growth by 44%.

Animal Protocol

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Molecular Weight*

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

Calculate the Mass of a compound required to prepare a solution of known volume and concentration
Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume

See Example

An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?

Enter 350.26 in the Molecular Weight (MW) box
Enter 10 in the Concentration box and choose the correct unit (mM)
Enter 5 in the Volume box and choose the correct unit (mL)
Click the “Calculate” button
The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.
