Solubility | DMSO : 5 mg/mL (ultrasonic and warming) mother liquor preservation: sub-package and freeze storage to avoid repeated freezing and thawing;-20 ℃,1 month;-80 ℃,6 months (after dilution, the solution temperature is low and storage may precipitate, try to use it now) Cell experiment: dissolve with DMSO first: dilute with culture medium then, and the dilution process is recommended to be carried out in stages to avoid too fast concentration change leading to compound precipitation. If the compound is precipitated during the dilution process, it can be redissolved by ultrasound. During dilution, ensure that the final concentration of DMSO in the working fluid should be below 0.1% as far as possible, and the maximum should not exceed 0.5%, and set up a DMSO control group with corresponding concentration. Animal experiment: Dissolve with DMSO first: dilute with water or normal saline, etc. The dilution process is recommended to be carried out in sections to avoid excessive concentration chang |

Use | EPZ005687 is a potent inhibitor of EZH2 (K(i) of 24 nM). EPZ005687 has greater than 500-fold selectivity against 15 other protein methyltransferases and has 50-fold selectivity against the closely related enzyme EZH1. The compound reduces H3K27 methylation in various lymphoma cells; this translates into apoptotic cell killing in heterozygous Tyr641 or Ala677 mutant cells, with minimal effects on the proliferation of wild-type cells. |
Target | EZH2 |
In vitro study | EPZ005687 inhibited PRC2 enzyme activity in a concentration-dependent manner with an IC50 of 54 nM. EPZ005687 directly inhibits PRC2 enzyme activity and does not function by disrupting protein-protein interactions between PRC2 subunits. EPZ005687 binds to the SAM pocket of the EZH2 SET domain and is a SAM-competitive inhibitor of EZH2 enzyme activity. The affinity of EPZ005687 for the PRC2 complex containing wild-type and Tyr641 mutant EZH2 was similar (within a 2-fold range), the enzyme acting on the A677G mutant had a significantly higher affinity (5.4-fold). EPZ005687 acts on a variety of different lymphoma cells to reduce H3K27 methylation. It has strong lethality to heterozygous Tyr641 or Ala677 mutant cells, and has the lowest effect on the proliferation of wild-type cells. EPZ005687 increased the G1 phase of the cell cycle and, correspondingly, decreased the S and G2/M phases. EPZ005687 acts on the lymphoma cell line with Tyr641 mutation, depresses the known EZH2 target gene, and affects the gene specifically inhibited by EZH2 Tyr641 mutation. |
