Ordering Information

Biological Activity

EPZ005687 is a potent and selective EZH2 inhibitor with a Ki of 24 nM in cell-free assays, demonstrating 50-fold selectivity over EZH1 and 500-fold selectivity against other protein methyltransferases. By inhibiting the enzymatic subunit of PRC2, EPZ005687 reduces global histone H3 lysine 27 trimethylation (H3K27me3) levels, leading to derepression of target genes and selective inhibition of cell proliferation and induction of apoptosis in EZH2-mutant lymphoma cells.

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
