| Outline of Final Research Achievements |
Development of nanocarriers for cancer thermal chemotherapy was carried out by precise design of copolymers based on sulfobetaine monomer, having a pair of positively and negatively charged groups in the side chain. The modification position of sulfobetaine copolymers by anticancer drug, doxorubicine, was examined and substitution at the ω terminus of the polymer showed the most efficient internalization to cancer cells. In addition, the presence of carboxy group at the α-terminus was effective compared to that of other functional groups. These polymers can be efficiently internalized into nerve cells and glial cells, and rhodamine modification enhanced the selective localization to mitochondria without reduction of its metabolic activity. These findings will give us a guideline for further development of nanocarriers.
