Targeting important protein-protein interactions involved in carcinogenesis or targeting the cell membrane of a cancer cell directly are just two of the ways in which foldamers (oligomeric molecules that fold into distinct shapes in solution) hold considerable potential in the treatment of cancer. From mimicking the local topography of the helical compound of interest by using covalently constrained foldamers to mimicking the topography of the natural helix such that the positions of key functional motifs are in an identical spatial orientation to match those presented by the original α-helix, synthetic foldamers have been used to mimic the natural foldamers that interact with proteins or the cell membrane. These targeted approaches have become established over a timeframe of more than a decade, and they continue to be included in the assortment of cancer targets being studied and the arsenal of chemotherapy compounds in development. These approaches are reviewed herein.
