Cell lines | Human Leukemia OCI-AML3 (AML-M4 subtype, DNMT3A-R882, NPM1c-mutated, p53-wildtype) cell lines |
Preparation method | The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. |
Reaction Conditions | 0.25 μM JQ1 for 24 h incubation |
Applications | BRD4 bromodomain inhibitor JQ1 is highly active against human leukemia OCI-AML3 mutation lines such as nucleophosmin (NPM1) and DNA methyltransferase 3 (DNMT3A). JQ1 causes caspase 3/7-mediated apoptosis and DNA damage response in these cells. JQ1 prevented BRD4-mediated recruitment of p53 to chromatin targets following its activation in OCI-AML3 cells resulting in cell cycle arrest and apoptosis in a c-MYC-independent manner. |
Animal models | Male C57BL/6J (The Jackson Laboratory) and BALB/cJ (Charles River) mice, 6–8 wk of age |
Dosage form | 10% (w:v) JQ1 solution in 2-hydroxypropyl-β-cyclodextrin solvent (Sigma-Aldrich); injected into the contralateral side of the abdomen |
Applications | JQ1 ablated cytokine production and blunted the “cytokine storm” in endotoxemic mice by reducing levels of IL-6 and TNF-α while rescuing mice from LPS-induced death. JQ1 benefited hyper-inflammatory conditions associated with high levels of cytokine production. |
Other notes | Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
| 产品描述 | Bromodomain Inhibitor, (+)-JQ1 isa 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.
