Description: Potent and selective BRPF1B bromodomain inhibitor
Chemical Name: N-[2,3-Dihydro-1,3-dimethyl-2-oxo-6-(1-pyrrolidinyl)-1H-benzimidazol-5-yl]-2-methoxybenzamide
Purity: ≥99% (HPLC)
Biological Activity for PFI 4
PFI 4 is a potent and selective BRPF1B bromodomain inhibitor (IC50 = 172 nM). Exhibits >100-fold selectivity for BRPF1 over a panel of other bromodomains including BRPF2 (BRD1), BRPF3 and BRD4. Disrupts BRPF1 binding to histone H3.3. Cell permeable. Inhibits osteoclastogenesis.
Licensing Information

Epigenetics Scientific Review
Written by Susanne Müller-Knapp and Peter J. Brown, this review gives an overview of the development of chemical probes for epigenetic targets, as well as the impact of these tool compounds being made available to the scientific community. In addition, their biological effects are also discussed. Epigenetic compounds available from Tocris are listed.
Epigenetics in Cancer Poster
This poster summarizes the main epigenetic targets in cancer. The dysregulation of epigenetic modifications has been shown to result in oncogenesis and cancer progression. Unlike genetic mutations, epigenetic alterations are considered to be reversible and thus make promising therapeutic targets.
Rheumatoid Arthritis Poster
Rheumatoid arthritis (RA) is a chronic destructive inflammatory autoimmune disease that results from a breakdown in immune tolerance, for reasons that are as yet unknown. This poster summarizes the pathology of RA and the inflammatory processes involved, as well as describing some of the epigenetic modifications associated with the disease and the potential for targeting these changes in the discovery of new treatments.
