Chemical Name: 2-Methoxy-N-(3-methyl-2-oxo-1,2,3,4-tetrahydroquinazolin-6-yl)benzenesulfonamide

Biological Activity

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.

Licensing Information

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.
