Biochem Physiol Actions: MS417, a (+)-JQ1 analog, is a potent inhibitor of bromodomain-containing protein 4 (BRD4) that is highly specific for BRD4-BD1 and BRD4-BD2. MS417 binds with similar affinity to BRD4-BD1 and BRD4-BD2 (Kd =36.1, and 25.4 nM), while bulky tBu of JQ1 prevents tight binding to the cavity at BD1.
