Ordering Information

Biological Activity

Valemetostat (DS-3201) is a selective dual inhibitor of enhancer of zeste homolog 1 (EZH1) and EZH2. By blocking EZH1 and EZH2 catalytic activity, Valemetostat decreases global histone H3 lysine 27 trimethylation (H3K27me3) levels and disrupts polycomb repressive complex 2 (PRC2)-mediated transcriptional repression. This inhibition leads to the reactivation of silenced tumor suppressor genes, resulting in cell cycle arrest, inhibition of cell proliferation, and induction of apoptosis in hematological malignancy models.

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).
