Biological Activity for PFI 1

PFI 1 is a 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.
