GSK5959 is a potent, selective and cell permeable BRPF1 bromodomain inhibitor with IC50 ~ 80 nM. It has >100-fold selectivity for BRPF1 over a panel of 35 other bromodomains, including BRPF2/3 and BET family bromodomains. A cellular protein interaction assay measuring the displacement of NanoLuc-tagged BRPF1 bromodomain from Halotagged histone H3.3 was employed to demonstrate GSK5959’s cell permeability and disruption of chromatin binding with IC50 ~0.98 µM.

How to use
GSK5959 was used at 10 µM final concentration in various in vitro assays. GSK-5959 (3a) also displays selectivity over the closely related family members, BRPF2 (100-fold) and BRPF3 (>1000-fold). GSK-5959 (3a) exhibits an EC50 = 0.98 μM) in cellular NanoBRET assay. GSK-5959 has no effect on TRIM24 SUMOylation.
