Crystal-structure
binding modes of four of the identified inhibitors
bound to BRD4(1). The left panel gives an overview of the binding
mode. The right panel gives a through-protein view highlighting the
binding mode of each KAc mimetic. Surface colors were generated using
the pocket colors in MOE. Green represents an enclosed surface, and
white, exposed. (A) Compound 1, (B) compound 3, (C) compound 4, and (D) compound 5.
