Description: GW841819X is an analogue of (+)-JQ1 and a novel inhibitor of BET bromodomains. GW841819X displayed activity in vivo against NUT-midline carcinoma, multiple myeloma, mixed-lineage leukemia, and acute myeloid leukemia. Bromodomain and extra-terminal (BET) proteins belong to a class of proteins collectively called epigenetic "readers". BET bromodomains have emerged as promising drug targets for treatment of cancers, inflammatory diseases, and other medical conditions.
