Bromodomain Inhibitor, (+)-JQ1 is a potent and highly specific inhibitor for the BET (bromodomain and extra-terminal) family of bromodomains. (+)-JQ1 binds to BRD4 bromodomains 1 and 2 with Kd values of ~ 50 and 90 nM, respectively. The binding is competitive with acetyl lysine. (+)-JQ1 can be a useful chemical probe to investigate the role of BET bromodomains in the transcriptional regulation of oncogenesis.
JQ1 exhibited strong dose-and time- dependent inhibition of BRDT and could significantly diminish the activity of a close structural relative of BRDT. A close look at JQ1 bound BRDT confirmed that the acetyl-lysine recognition site of BRDT was blocked. [1]
JQ1 does not produce sedative or anxiolytic effects and is instead a potent and selective inhibitor of the bromodomain testis-specific protein BRDT [2], which is essential for chromatin remodeling during spermatogenesis. By blocking BRDT, JQ1 effectively blocks the production of sperm in the testes and consequently produces effective contraception, without the negative side effects associated with previously researched hormonal contraceptives for men.
