GSK4027 Chemical Properties,Usage,Production

Description

GSK4027 is a potent and selective chemical probe for the PCAF/GCN5 bromodomain. GSK4027 has PCAF TR-FRET pIC50 = 7.4 ; PCAF BROMOscan pKi = 8.9; GCN5 BROMOscan pKi = 8.9; PCAF NanoBRET pIC50 =7.2; BRD4 BD1 TR-FRET pIC50 < 4.3. GSK4027 shows high potency for the PCAF/GCN5 bromodomain, high solubility, cellular target engagement, and ≥18000-fold selectivity over the BET family, together with ≥70-fold selectivity over the wider bromodomain families. p300/CREB binding protein associated factor (PCAF/KAT2B) and general control nonderepressible 5 (GCN5/KAT2A) are multidomain proteins that have been implicated in retroviral infection, inflammation pathways, and cancer development.

in vitro

Herein, this study reports GSK4027 as a chemical probe for the PCAF/GCN5 bromodomain, together with GSK4028 as an enantiomeric negative control._x000D_ _x000D_ Reference: J Med Chem. 2017 Jan 26;60(2):695-709. https://pubmed.ncbi.nlm.nih.gov/28002667/

target

GSK 4027 is a chemical probe for the PCAF/GCN5 bromodomain with an pIC50 of 7.4±0.11 for PCAF in a time-resolved fluorescence resonance energy transfer (TR-FRET) assay.
