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. JQ1 is known to suppress cell proliferation and therefore, can be used as a therapeutic drug for a number of cancers including multiple myeloma and acute myeloid leukemia.

Application

(+)-JQ1 has been used in flow cytometry assay, cell viability assay and quantitative PCR assay in order to investigate on the reversal of HIV-1 latency.

Packaging

Biochem/physiol Actions

(+)-JQ1 is a high affinity, potent and selective inhibitor of BET bromodomain proteins, including BRD2, BRD3, BRD4 and BRDT. (+)-JQ1 (also known as SGCBD01), the active enantiomer of (+/-)-JQ1, inhibits Brd4 (bromodomain-containing 4), which forms complexes with chromatin via two tandem bromodomains (BD1 and BD2) that bind to acetylated lysine residues in histones and Brd4 association with acetylated chromatin is believed to regulate the recruitment of elongation factor b and additional transcription factors to specific promoter regions. The nuclear protein in testis (NUT) gene is known to form fusions with Brd4 that create a potent oncogene, leading to rare, but highly lethal tumors referred to as NUT midline carcinomas (NMC). (+)-JQ1 inhibits recruitment and binding of Brd4 to TNFa and E-selectin promoter elements, and accelerates recovery time in FRAP (fluorescence recovery after photobleaching) assays using GFP-Brd4. Thus (+)-JQ1 is a useful tool to study the role of Brd4 in transcriptional initiation.
