| Description |
A cell-permeable benzodiazepine compound that binds the tandem bromodomains of BET (bromodomain and extra terminal domain) family members BRD2 (1-473), BRD3 (1-434), and BRD4 (1-477) with high affinity ( K d = 61.3, 50.5, and 55.2 nM, respectively, by ITC) and effectively competes against tetra-acetylated H4 peptide (Millipore cat. no. 12-379) for BRD2/3/4 binding (IC 50 = 32.5, 42,4, and 36.1 nM, respectively, in competitive equilibrium binding assays), while exhibiting little affinity toward 5 other bromodomain-containing proteins (ATAD2, BAZ2B, CREBBP, PCAF, SP140) or a panel of 38 cellular enzymes, GPCRs, transporters, and ion channels
