Molibresib (I-BET-762)

InformationMolibresib (I-BET-762) Molibresib (I-BET-762, GSK525762, GSK525762A) is an inhibitor for BET proteins with IC50 of ~35 nM in a cell-free assay, suppresses the production of proinflammatory proteins by macrophages and blocks acute inflammation, highly seIn vitroI-BET-762 is an inhibitor for BET (bromodomain and extra terminal domain) proteins, BRD2, BRD3 and BRD4, binds to the tandem bromodomains of BET with Kd of 50.5–61.3 nM, displaces a tetra-acetylated H4 peptide prebound to tandem bromodomains of BET with IC50 of 32.5–42.5 nM in FRET analysis. I-BET-762 occupies the acetyl-lysine binding pocket of BET proteins and inhibits binding of BET proteins to acetylated histones, thus disrupts the formation of the chromatin complexes essential for expression of inflammatory genes. I-BET-762 treatment during the first 2 d of differentiation alters CD4+ T-cell cytokine production, up-regulated expression of several antiinflammatory gene products and down-regulated expression of several proinflammatory cytokines.In vivoI-BET-762 confers protection against lipopolysaccharide-induced endotoxic shock and bacteria induced sepsisa. Single dose of I-BET applied at 1.5 h after LPS injection cures the mice. Twice-daily injections of I-BET for 2 days protects mice against death caused by sepsis. Limited treatment with I-BET-762 exclusively during early priming inhibited the ability of Th1-differentiated 2D2 T cells to induce neuroinflammation in a mouse model of experimental autoimmune encephalomyelitis (EAE).Cell Datacell lines：Concentrations：~500 nMIncubation Time：60–72 hPowder Purity:≥97%.
