BimBH3 peptide features an α-helix with hotspot residues on multiple faces. Compound 5 (6-bromo-2,3-dihydroxyanthracene-9,10-dione), which adopts a rigid-plan amphipathic conformation, was designed and evaluated as a scaffold to mimic two faces of Bimα-helix. It reproduced the functionalities of both D67 and I65 on two opposing helical sides. Moreover, it maintained the two-faced binding mode during
