The bromodomain and extra terminal (BET) proteins interact with acetylated lysine-containing sequences on target proteins via their bromodomains, commonly altering gene transcription. The human BET proteins contain two bromodomains, the first (BD1) being closer to the N-terminus than the second (BD2). RVX-208 is a selective antagonist of BET bromodomains, binding with 10-100-fold higher affinity for BD2 (IC₅₀ = 0.04-0.28 μM) over BD1 (IC₅₀ = 1.8-3.1 μM). RVX-208 causes the selective release of BET proteins from chromatin in cells. It interferes with the BET protein BRD4, resulting in an increased expression of apolipoprotein (Apo) A₁ in cells, mice, monkeys, and humans. RVX-208 also reduces atherosclerosis in hyperlipidemic ApoE-deficient mice.

RVX-208 is a selective antagonist of bromodomain and extra terminal (BET)’s bromodomains.
