    Small-molecule hits for the bromodomains of CREBBP and BAZ2B have been identified by scaffold hopping followed by docking of a set of ∼200 compounds containing the acetyl indole scaffold. Chemical synthesis of nearly 30 derivatives has resulted in ligands of representatives of three subfamilies of human bromodomains with favorable ligand efficiency. The X-ray crystal structures of three different bromodomains (CREBBP, BAZ2B, and BRPF1b) in complex with acetyl indole derivatives reveal the influence of the gatekeeper residue on the orientation of small-molecule ligands in the acetyl lysine binding site.
