I-BET 151 dihydrochloride
Chemical Name: 7-(3,5-Dimethyl-4-isoxazolyl)-1,3-dihydroxy-8-methoxy-1-[(1R)-1-(2-pyridinyl)ethyl]-2H-imidazo[4,5-c]quinolin-2-one dihydrochloride
Purity: ≥98%
Biological Activity
I-BET 151 dihydrochloride is a BET bromodomain inhibitor; blocks recruitment of BET to chromatin. Induces apoptosis and G0/G1 cell cycle arrest in MLL-fusion leukemic cell lines in vitro (IC50 values are 15, 26, 120 and 192 nM for NOMO1, MV4;11, MOLM13 and RS4;11 cell lines respectively); reduces BCL2 expression in NOMO1 cells. Improves survival in two rodent models of MLL-fusion leukemia in vivo. Enhances differentiation of human iPSC into megakaryocytes. Also enhances fibroblast reprogramming to hiPSCs at low concentration.For more information about how I-BET 151 dihydrochloride may be used, see our protocol: Transdifferentiating Fibroblasts into Neurons.
