By conducting a structure-activity relationship study of the backbone of a series of oligoamide-foldamer-based alpha-helix mimetics of the Bak BH3 helix, we have identified especially potent inhibitors of Bcl-x(L). The most potent compound has a K-i value of 94 nM in vitro, and single-digit micromolar IC50 values against the proliferation of several Bcl-x(L)-overexpressing cancer cell lines.
