Product overview

  • Name
  • Short description
    Potent, selective BET bromodomain inhibitor. Cell permeable.
  • Biological description

    (+)-JQ1 (JQ1) is a potent, selective and cell permeable inhibitor of the BET (Bromodomain and Extra-Terminal domain) protein family.

    JQ1 selectively binds the BRD2, BRD3, BRD4 and BRDT bromodomain proteins (IC50 values are 17.7, 76.9 and 32.6 nM at BRD2, BRD4(N) and BRD4(C) respectively).

    JQ1 shows highest affinity for BRD4. JQ1 displaces BRD4 from chromatin by competitively binding to the acetyl-lysine recognition pocket to inhibit transcription.

    JQ1 shows effects on tumour growth and survival, cell cycle arrest and differentiation. It has antitumor and anti-angiogenic properties.

    JQ1 shows a short half-life of one hour.
