Bismuth-Cyclized Cell-Penetrating Peptides
Ritchey, Jeremy L ; Filippi, Lindsi ; Ballard, Davis , et al. Mol. Pharmaceutics,2024,21(10):5255-5260. DOI: 10.1021/acs.molpharmaceut.4c00688 PubMed ID: 39223839

Abstract: Intracellular delivery of biological cargos, which would yield new research tools and novel therapeutics, remains an active area of research. A convenient and potentially general approach involves the conjugation of a cell-penetrating peptide to a cargo of interest. However, linear CPPs lack sufficient cytosolic entry efficiency and metabolic stability, while previous backbone cyclized CPPs have several drawbacks including the necessity for chemical synthesis and posttranslational conjugation to peptide/protein cargos and epimerization during cyclization. We report here a new class of bismuth cyclized CPPs with excellent cytosolic entry efficiencies, proteolytic stability, and potential compatibility with genetic encoding and recombinant production.
Keywords: bismuth ; cell-penetrating peptides ; drug delivery ; endosomal escape ; peptide cyclization
