Beschreibung
(±) JQ1 (1268524-69-1) 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.1 Chiral version is available for purchase (Cat#10-1584).
Verwenden
rac-Tert-butyl 2-(4-(4-Chlorophenyl)-2,3,9-trimethyl-6H-thieno[3,2-f][1,2,4]triazolo[4,3-a][1,4]diazepin-6-yl)acetate is the isomer of (S)-(+)-Tert-butyl 2-(4-(4-Chlorophenyl)-2,3,9-trimethyl-6H-thieno[3,2-f][1,2,4]triazolo[4,3-a][1,4]diazepin-6-yl)acetate (T117580), which is BET bromodomain inhibitor, also activates HIV latency through antagonizing Brd4 inhibition of Tat-transactivation.
Verwenden
(±)-JQ1 has been used to study its effect on adipogenesis, by analysing the its impact on the regulation of genes involved in this process especially peroxisome proliferator-activated receptor (PPAR-g), the CCAAT/enhancer-binding protein (C/EBPa) and, STAT5A and B. JQ1 has been used in drug binding assays as a chemical inhibitor of BRD4 to study the CRBN′s substrate recruiting function in mouse and human.
Definition
ChEBI: LSM-6732 is an organonitrogen heterocyclic compound, an organosulfur heterocyclic compound and a tert-butyl ester.
Biochem/physiol Actions
(±)-JQ1 is a Brd4 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.
