NI-57 is a potent inhibitor of the bromodomain of the BRPFs that binds to BRPF1B, BRPF2, and BRPF3 with Kd values of 31, 108, and 408 nM, respectively [1].
The bromodomain and PHD finger-containing protein 1, 2, 3 (BRPF1/2/3) are scaffolding subunit of the MOZ/MORF histone acetyltransferase complexes that links together KAT6A/B, ING5 and hEAF6 in the tetrameric assembly. BRPF1 (BR140 or Peregrin) is important in the maintenance of expression levels of Hox genes and the development of axial skeleton, multiple tissues and the hematopoietic system [2][3].
NI-57 is a potent inhibitor of the bromodomain of the BRPFs and acts as a chemical probe for the bromodomains of the BRPF family of proteins (BRPF1/2/3). As determined by isothermal titration calorimetry, NI-57 binds to BRPF1B, BRPF2, and BRPF3 with Kd values of 31, 108, and 408 nM, respectively. As measured by both biophysical and biochemical methods, NI-57 exhibited selective against other non-Class IV bromodomains, including the BETs. In the BRPF2 FRAP assay, NI-57 at 1 μM prevented binding of full-length BRPF2 to chromatin [1].
