PFI-3 --- SMARCA Bromodomains Inhibitor

PFI-3 is a novel potent, selective and cell permeable inhibitor of SMARCA4 and PB1(5) bromodomains with IC50 ~ 89 nM and 48 nM respectively. It also inhibits SMARCA2, but has no interaction with the other sub-family branches including PB1(2-4) and a kinase panel of 36 kinases. It accelerates FRAP recovery in cells at a concentration of 1 μM. The SWI/SNF-related, Matrix-associated, Actin-dependent Regulator of Chromatin (SMARC) proteins integrate into complexes that remodel chromatin. The SMARC family A (SMARCA) members SMARCA2 (also known as BRM) and SMARCA4 (also known as BRG1) are helicases that contain structurally-related bromodomains for binding acetylated lysine residues on target proteins. PFI-3 is a very useful chemical probe to study the key chromatin remodeling and transcription control.
