Description
PFI-1 is an inhibitor of BET bromodomains (BRDs) that prevents the association of BET with histones; it acts as an acyl-lysine (Kac) mimetic inhibitor, binding the Kac site of BRD2 and BRD4. PFI-1 exhibits anti-inflammatory and anticancer activities. In H202-treated bronchial epithelial cells, PFI-1 decreases expression of IL-6 and CXCL8. In leukemia cells, PFI-1 downregulates expression of Myc and AurKB, inducing G1 phase cell cycle arrest and suppressing cell growth.
