Biochem/physiol Actions

MS645 is a cell penetrant bivalent bromodomain (BRD) inhibitor that inhibits the tandem BD1/BD2 of BRD4. It potently represses BRD4 transcriptional activity in solid-tumor cells including TNBC. MS645 potently inhibits IL-6 expression MDA-MB-231 cells. MS645 exhibits sustained blockade of BRD4 by inhibition of BRD4 interactions with transcription enhancer/mediator proteins MED1 and YY1.

The importance of BET protein BRD4 in gene transcription is well recognized through the study of chemical modulation of its characteristic tandem bromodomain (BrD) binding to lysine-acetylated histones and transcription factors. However, while monovalent inhibition of BRD4 by BET BrD
