Title Plasmid DNA delivery by arginine-rich cell-penetrating peptides containing unnatural amino acids.
Journal Bioorg. Med. Chem.
Abstract Cell-penetrating peptides (CPPs) have been developed as drug, protein, and gene delivery tools. In the present study, arginine (Arg)-rich CPPs containing unnatural amino acids were designed to deliver plasmid DNA (pDNA). The transfection ability of one of the Arg-rich CPPs examined here was more effective than that of the Arg nonapeptide, which is the most frequently used CPP. The transfection efficiencies of Arg-rich CPPs increased with longer post-incubation times and were significantly higher at 48-h and 72-h post-incubation than that of the commercially available transfection reagent TurboFect. These Arg-rich CPPs were complexed with pDNA for a long time in cells and effectively escaped from the late endosomes/lysosomes into the cytoplasm. These results will be helpful for designing novel CPPs for pDNA delivery.
