Description: | PFI-4 is a potent and selective and cell permeable BRPF1 bromodomain inhibitor (IC50 = 80 nM). Exhibits >100-fold selectivity for BRPF1 over a panel of other bromodomains including BRPF2 (BRD1), BRPF3 and BRD4. |
Target: | IC50 value: 80 nM Target: BRPF1 |
In Vitro: | Disrupts BRPF1 binding to histone H3.3. PFI-4 is a chemical probe that specifically binds to the bromodomain of BRPF1 with a Kd =13 nM as determined by ITC. It reduces recovery time in triple BRD cell construct in FRAP, inhibiting binding to tri-acetylated histone 4 (residues 1-21). It has much lower affinity for bromodomain 1 of BRD4 (Kd = >50 μM) and is selective for BRPF1 over BRPF2 and BRPF3. PFI-4 is potent in cells, with an IC50 value of 250 nM. |
