| Title | Accumulation of arginine-rich cell-penetrating peptides in tumors and the potential for anticancer drug delivery in vivo. |
| Journal | J Control Release |
| Abstract |
We investigated the biodistribution of arginine-rich cell-penetrating peptides (CPPs) in tumor-xenografted nude mice after intravenous injection of fluorescently labeled CPPs using in vivo imaging. The CPPs used included HIV-1 Tat (48-60), penetratin, and the L- and D-enantiomers of oligoarginines (8, 12, and 16 residues), all of which are reported to have high cell penetration. Among the tested peptides, high accumulation in tumors was observed for the D-form of octaarginine (r8), and glycosaminoglycans played a key role. Injection of an r8-doxorubicin conjugate (4mg doxorubicin/kg) effectively suppressed tumor proliferation, with no significant decrease in mouse weight, whereas administration of doxorubicin itself (6mg/kg), yielding a similar degree of tumor-growth suppression, resulted in significant weight loss. These results suggest the potential of r8 as a prototypic tumor-targeting vector. |
