(R)-(-)-JQ1 enantiomer, the stereoisomer(+)-JQ1, showed no significant interaction with any bromodomain. (+)-JQ1 is an inhibitor for the BET which targets the BET bromodomain. The (R)-(-)-JQ1 enantiomer stereoisomer has no appreciable affinity to BET bromodomains, whereas S-enantiomer pure (+)-JQ1 binds to BRD4 bromodomains 1 and 2 with Kd values of ~ 50 and 90 nM, respectively.
