- 產(chǎn)品描述：
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.
- 靶點： EZH2
- 體外研究： EPZ005687 shows concentration-dependent inhibition of PRC2 enzymatic activity with an IC50 value of 54±5 nM. EPZ005687 specifically inhibits H3K27 methylation in lymphoma cells. EPZ005687 has a notable effect on proliferation of the EZH2Y641F-bearing cell line. EPZ005687 decreases proliferation in mutant but not wild-type EZH2 lymphoma cells. EPZ005687 (0.5, 1, 5 and 10 µM) induces an obvious apoptosis of U937 cells in a dose-dependent manner. EPZ005687 inhibits obviously the proliferation of U937 cells but has weak effect on the proliferation of NBMCD34+ cells. EPZ005687 induces G1 phase blocking and decreases the percentage of cells in S phase in U937 cells. In addition, EPZ005687 produces obviously depletion of H3K27 methylation in U937 cells, but hardly has effect on the H3K27 methylation of NBMCD34+ cells.
- 細(xì)胞實驗： Plating densities are determined for each cell line on the basis of linear log-phase growth. Cells are counted and split back to the original plating density in fresh medium with EPZ005687 on days 4 and 7.(Only for Reference) Cell lines: OCI-LY19, WSU-DLCL2, Pfeiffer

- 溶解度： DMSO : 5 mg/mL (ultrasonic and warming)
母液保存：分裝凍存，避免反復(fù)凍融；-20℃，1個月；-80℃，6個月（稀釋后溶液溫度低保存可能會析出，盡量現(xiàn)用現(xiàn)配）
細(xì)胞實驗:先用DMSO溶解：再用培養(yǎng)基進(jìn)行稀釋，稀釋過程建議分段進(jìn)行，避免濃度變化過快導(dǎo)致化合物析出。若稀釋過程中出現(xiàn)化合物析出的情況， 可采用超聲的方法使其復(fù)溶。在稀釋時要確保工作液中 DMSO 的終濃度盡量在0.1%以下，不要超過0.5%，并設(shè)置相應(yīng)濃度的DMSO對照組。
動物實驗：先用DMSO溶解：再用水或者生理鹽水等去稀釋，稀釋過程建議分段進(jìn)行，避免濃度變化過快導(dǎo)致化合物析出。若稀釋過程中出現(xiàn)化合物析出的情況， 可采用超聲的方法使其復(fù)溶。可以通過添加助溶劑來幫助溶解，比如植物油、Tween80、甘油、羧甲基纖維素鈉和PEG400等。具體方式請參考文獻(xiàn)。懸濁液可用于口服和腹腔注射，不會影響產(chǎn)品活性。
