Potent BET bromodomain inhibitor; exhibits inhibitory activity at bromodomain-containing protein (BRD) 2 and BRD4 (IC50 values are 98 and 220 nM respectively). Induces apoptosis and G1 cell cycle arrest in BET inhibitor-sensitive cell lines (MV4;11). Also downregulates Aurora B expression in MV4;11 cells. Cell permeable.
This probe is supplied in conjunction with the Structural Genomics Consortium. For further characterization details, please visit the PFI 1 probe summary on the SGC website.

Cell Cycle & DNA Damage Repair Poster
In normal cells, each stage of the cell cycle is tightly regulated, however in cancer cells many genes and proteins that are involved in the regulation of the cell cycle are mutated or over expressed. Adapted from the 2015 Cancer Product Guide, Edition 3, this poster summarizes the stages of the cell cycle and DNA repair. It also highlights strategies for enhancing replicative stress in cancer cells to force mitotic catastrophe and cell death.
