Abstract
Five new cyclic peptoids containing (2S,4R)-4-hydroxyproline (Hyp) residues have been designed and synthesized using a mixed “submonomer/monomer” approach. Alkali metal cation affinities and ion transport activities were assessed by experimental (NMR and HPTS assay in liposomes) and computational methods. Easy functionalization of hydroxyproline residues afforded a bouquet of cyclic oligomers showing correlation between ion transport abilities and cytotoxic activities on selected human cancer cell lines.
