Functions

JQ1 is a potent BET bromodomain inhibitor.   IC50 = 17.7, 32.6, 76.9 and 12942 nM respectively for BRD2 (N-terminal (N)), BRD4 (C-terminal (C)), BRD4 (N) and CREBBP respectively. Competitive binding by JQ1 displaces the BRD4 fusion oncoprotein from chromatin, prompting squamous differentiation and specific antiproliferative effects in BRD4-dependent cell lines and patient-derived xenograft models establishing proof-of-concept for targeting protein-protein interactions of epigenetic readers.

Application Procedures

First dissolved in DMSO (up to 9 mg/ml) or in Ethanol (up to 9 mg/ml) with warming, then diluted to aqueous buffer. Solutions in DMSO or ethanol may be stored at -20° for up to 2 months.

Research use only.
