General description

JQ1 is a member of the triazolo-diazepine compound family which functions as a pan-BET (bromodomain and extra-terminal motif) family inhibitor. Its core structure is composed of thienodiazepine.

Biochem/physiol Actions

(-)-JQ1 is the negative control probe for (+)-JQ1, the active enantiomer of (+/-)-JQ1, which is a potent and selective BET bromodomain inhibitor. (-)-JQ1 shows no significant interaction with BRD1-4 or other bromodomains.

For characterization details of the active probe, (+)-JQ1, please visit the JQ1 probe summary on the Structural Genomics Consortium (SGC) website.

(+)-JQ1, the active enantiomer, is available from Sigma. To learn more about and purchase (+)-JQ1, click here.
