Abstract
- and α-helical structures under the amphiphilic cell-membrane-mimicking environment. Poly(LysAibXaa) exhibited long-term internalization and thus high accumulation in live cells, which is attributed to the improvement in the resistance to proteolytic digestion as a result of the incorporation of Aib residues into the peptide backbone. We presented a simple molecular design and synthesis of efficient CPPs applicable to both human and plant cells with long-term stability and negligible cytotoxicity.
