We describe the design, synthesis and cell-membrane translocation properties of a series of beta-peptides with the general sequence fluorescein-Adoa-(beta-homolysine)(n)-NH(2), n=5-8 and Adoa=8-amino-3,6-dioxaoctanoic acid. These beta-peptides are able to cross the cytoplasmic membrane and accumulate in the nucleus of mammalian cells.
