Cas Number:1268524-70-4
Molecular Formula:C23H25ClN4O2S
Molecular Weight:456.9882 g/mol
Description:JQ1 is a thienotriazolodiazepine and a potent inhibitor of the BET family of bromodomain proteins which includeBRD2, BRD3, BRD4, and the testis-specific protein BRDT in mammals. BET inhibitors structurally similar to JQ1 are being tested in clinical trials for a variety of cancers including NUT midline carcinoma. It was developed by the James Bradner laboratory at Brigham and Women's Hospital and named after chemist Jun Qi. The chemical structure was inspired by patent of similar BET inhibitors by Mitsubishi Tanabe Pharma [WO/2009/084693]. Structurally it is related to benzodiazepines. While widely used in laboratory applications, JQ1 is not itself being used in human clinical trials because it has a short half life.
