Suppression of inflammation by a synthetic histone mimic

Post-translationally modified histones are recognized by effector proteins which contain specific binding modules; for example, the bromodomain-containing BET proteins bind acetylated lysine residues during gene activation. Here a synthetic small molecule is described that interferes with the binding of certain BET family members to acetylated histones. The compound inhibits activation of pro-inflammatory genes in macrophages and has activity in a mouse model of inflammatory disease.
