| | I-BET151 (GSK1210151A) Usage And Synthesis |
| Biological activity | I-BET151 (GSK1210151A) is a novel selective BET inhibitor for BRD2, BRD3 and BRD4 with IC50 of 0.5 μM, 0.25 μM, and 0.79 μM in cell-free assays, respectively. | | In vitro | I-BET151 exhibits potent selectivity over an extensive range of diverse protein types such as COX-2, P450, Aurora B, GSK3β, PI3K-γ, GPCR, ion channels, and transporters. Similar to I-BET762 (GSK525762A), I-BET151 displays potent binding affinity to BRD2, BRD3 and BRD4 with KD of 0.02-0.1 μM, and significantly inhibits lipopolysaccharide-stimulated IL-6 cytokine production in human peripheral blood mononuclear cells (PBMC) and whole blood (WB) as well as rat WB with IC50 of 0.16 μM, 1.26 μM, and 1.26 μM, respectively. I-BET151 (0.5 or 5 μM) inhibits the binding of BETs (BRD2, BRD3, BRD4, and BRD9) but not the binding of 23 other bromodomain proteins in HL60 nuclear extract to acetylated histone peptides. I-BET151 has potent efficacy against cell lines harboring different MLL-fusions such as MV4;11, RS4;11, MOLM13, and NOMO1 cells with IC50 of 15-192 nM. Consistently, I-BET151 completely ablates the colony-forming potential of MLL-fusion-driven leukaemias (MOLM13) but not leukaemias driven by tyrosine kinase activation (K562). I-BET151 also displays potent efficacy in both liquid culture and clonogenic assays using primary murine progenitors transformed with either MLL-ENL or MLL-AF9. I-BET151 treatment significantly induces apoptosis and prominent G0/G1 arrest in MLL-fusion cell lines driven by distinct MLL fusions (MOLM13 and MV4;11 containing MLL-AF9 and MLL-AF4, respectively) but not the K562 cells, probably due to the inhibition of transcription of BCL2, C-MYC and CDK6 by blocking the recruitment of BRD3/4, PAFc and SEC components into transcriptional start site (TSS). | | In vivo | Administration of I-BET151 at 30 mg/kg/day significantly inhibits tumor growth of murine MLL-AF9 and human MLL-AF4 leukaemia in mice, and provides marked survival benefit. | | References | http://www.selleckchem.com/products/i-bet151-gsk1210151a.html | | Description | The bromodomain and extra terminal domain (BET) family of proteins including BRD2, BRD3, and BRD4 play a key role in many cellular processes, including inflammatory gene expression, mitosis, and viral/host interaction by controlling the assembly of histone acetylation-dependent chromatin complexes. I-BET151 is an isoxazole class pan-BET family inhibitor, blocking BRD2, BRD3, and BRD4 with IC50 values of 0.5, 0.25, and 0.79 μM, respectively. Through this action, it blocks the growth of leukemic cell lines driven by mixed lineage leukemia (MLL) fusions at nanomolar concentrations, whereas tyrosine kinase activated cells were much less sensitive. Specifically, I-BET151 induces apoptosis via reduced expression of BCL2 or triggers G0/G1 cell cycle arrest in MLL-fusion cell lines. I-BET151 is effective in vivo, suppressing MLL leukemia progression in two different mouse models. | | Chemical Properties | Off-White Solid | | Uses | GSK1210151A or I-BET151 has been used to study its inhibitory effect on BET (bromodomain and extra terminal) recruitment to chromatin in treating MLL (mixed-lineage leukemia)-fusion leukemia. | | Uses | I-BET 151 is part of a novel series of quinoline isoxazole BET family bromodomain inhibitors, a family of four proteins that selectively bind to aceylated lysine residues in histone. I-BET 151 play ke
y roles in many cellular processes, including anti-inflammatory gene expression, mitosis, and viral/host interaction by controlling the conformation of histone acetylation -dependent chromatin complex
es. Studies have shown that I-BET 151 increased ApoA1 expression within the nanomolar range in human hepatic cell line HepG2. The upregulation by I-BET 151 suggested potential anti-inflammatory activi
ties upon administration. | | Definition | ChEBI: 7-(3,5-dimethyl-4-isoxazolyl)-8-methoxy-1-[(1R)-1-(2-pyridinyl)ethyl]-3H-imidazo[4,5-c]quinolin-2-one is an imidazoquinoline. | | Biochem/physiol Actions | GSK1210151A (I-BET151) is an inhibitor of the BET (bromodomain and extra terminal domain protein) family of acetyl-lysine recognizing, chromatin ′adaptor′ proteins. GSK1210151A displaces BRD3 and BRD4, PAFc and SEC components from chromatin resulting in inhibition of transcription at key genes (BCL2, C-MYC and CDK6) involved in the initiation of mixed lineage leukemia (MLL). GSK1210151A (I-BET151) showed good efficacy in 2 MLL animal models. | | target | BRD2 |
