A series of novel cyclic marinopyrroles were designed and synthesized. Their activity to disrupt the binding of the pro-apoptotic protein, Bim, to the pro-survival proteins, Mcl-1 and Bcl-xL
, was evaluated using ELISA assays. Both atropisomers of marinopyrrole A (1
) show similar potency. A tetrabromo congener 9
is two-fold more potent than 1
. Two novel cyclic marinopyrroles (3
) are two- to seven-fold more potent than 1
