(+)-JQ1 is a potent BET bromodomain inhibitor with IC50 values of 77 nM and 33 nM for BRD4 bromodomain 1 and BRD4 bromodomain 2, respectively. This small molecule competitively binds to the acetyl-lysine recognition pocket of BET bromodomains, which in turn displaces BET proteins from chromatin (1). The BET family of proteins are associated in many different cellular processes, including mitosis, viral/host interaction, and inflammatory gene expression (2-4). Studies have shown that (+)-JQ1 induced autophagy through LKB1/AMPK pathway activation can inhibit bladder cancer (BC) cell proliferation (5).
