Cellular Use Rating
It is interesting to note the targeting approach of engaging two bromodomains simultaneously using a synthetic agent with a bivalent binding mode.

In Model Organisms
This is an extremely potent (picomolar) inhibitor of BRD4. Biophysical evidence suggests this pseudosymmetric molecule binds bivalently to the tandem BD1/2 domains (at nonsaturating ligand concentrations),...

Cellular Use Rating
This is a highly potent (10 nM in cells) BET-family inhibitor.
