| Outline of Final Research Achievements |
Consequently, peptide-dendrimer or peptide-liposome conjugates showed their accumulation to the liver in vivo, although its maginitude of accumulation was decreased in comparison with those of the dendrimer or liposome alone. Taking this into consideration, we changed the strategy from generating the peptide-nano particle conjugates that enhance the delivery to the target tumor tissues, to obtain the highly efficient tumor-targeting peptides by isolating them from the random peptide library. As a result, we succeeded identifying the novel superior tumor-homing peptides such as pancreatic cancer-homing, bile duct cancer-hoiming, and glioblastoma-homing peptides. Patentapplications for these tumor-targeting peptides have been completed, and we are preparing PCT application now.
