    Feb 15, 2013 · Short peptide motifs such as FΦR 4 provide useful and likely general transporters for intracellular delivery of cyclic peptides. If a target-binding cyclic peptide is already available, one may simply replace the residues noncritical for target binding with FΦR 4. The designed cyclic peptides should have ring sizes of 7 to 13 amino acids; larger rings will likely have poor cellular uptake activities, whereas cyclic peptides …Author: Ziqing Qian, Tao Liu, Yu Yu Liu, Roger Briesewitz, Amy M.

    Here, we report a potentially general approach for intracellular delivery of cyclic peptides. Short peptide motifs rich in arginine and hydrophobic residues (e.g., FφRRRR, where φ is l -2-naphthylalanine), when embedded into small- to medium-sized cyclic peptides (7–13 amino acids), bound to the plasma membrane of mammalian cultured cells...Author: Ziqing Qian, Tao Liu, Yu Yu Liu, Roger Briesewitz, Amy M.

    May 06, 2013 · In summary, a new carrier system for the delivery of cell impermeable phosphopeptides was discovered using cyclic octapeptide [WR] 4 containing alternative tryptophan and arginine residues. The cellular uptake of F′-PEpYLGLD was enhanced by 27-fold in the presence of [WR] 4 , and was found to be time-dependent.Author: Amir Nasrolahi Shirazi, Rakesh Kumar Tiwari, Donghoon Oh, Antara Banerjee, Arpita Yadav, Keykavous P...

    May 10, 2016 · In this study, a family of small, amphipathic cyclic peptides was found to be highly efficient CPPs, with cytosolic delivery efficiencies of up to 120% (compared to 2.0% for Tat). These cyclic CPPs bind directly to the plasma membrane phospholipids and enter mammalian cells via endocytosis, followed by efficient release from the endosome.Author: Ziqing Qian, Agnieszka Martyna, Ryan L.
