Arginine-rich heterotrimeric collagen-like peptides were prepared, and their cellular uptake efficiency was evaluated. The spatial arrangement of the Arg residues (blue in picture) on the triple-helix surface significantly affected the efficacy of the cellular uptake. The collagen-like triple-helical conformation provides these cell-penetrating peptides with a high resistance to proteases. O=L-4-hydroxyproline.
