Ordering Information

Biological Activity

INCB054329 is a potent bromodomain and extraterminal domain (BET) inhibitor targeting BRD2, BRD3, BRD4, and BRDT. By preventing the binding of BET proteins to acetylated lysine residues on histones, it disrupts chromatin interactions and transcriptional machinery assembly. This suppression leads to down-regulation of oncogenic signaling pathways and downstream targets such as MYC, resulting in inhibition of cell proliferation and induction of apoptosis in cancer 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).
