Crystal structure of human BRD4(1) in complex with CN750
Structural highlights
Disease[BRD4_HUMAN] Note=A chromosomal aberration involving BRD4 is found in a rare, aggressive, and lethal carcinoma arising in midline organs of young people. Translocation t(15;19)(q14;p13) with NUT which produces a BRD4-NUT fusion protein.[1] [2] Function[BRD4_HUMAN] Plays a role in a process governing chromosomal dynamics during mitosis (By similarity). Publication Abstract from PubMedA new series of quinazoline-based analogs as potent bromodomain-containing protein 4 (BRD4) inhibitors is described. The structure-activity relationships on 2- and 4-position of quinazoline ring, and the substitution at 6-position that mimic the acetylated lysine are discussed. A co-crystallized structure of 48 (CN750) with BRD4 (BD1) including key inhibitor-protein interactions is also highlighted. Together with preliminary rodent pharmacokinetic results, a new lead (65, CN427) is identified which is suitable for further lead optimization.
