제목 Photosensitizer Loaded Cationic Dual Stimuli Responsive Lipopolymer Formulation for the Controlled Delivery of Ce6 in Tumor Targeted Photodynamic Therapy
초록 In our study site specific cationic dual responsive photosensitizer loaded liposomal nanocarriers prepared for the controlled intracellular release of chlorine e6 (Ce6) in a targeted tumors related to their microenvironments. The system was developed by the formulation of phosphatidylcholine (PC), posphatidylethanolamine-p(L-Histidine)40 (PE-p(His)40), folic acid conjugated PE-p(N-isopropyl acrylamide)40 (PE-p(NIPAM)40). The designing features providing the promising properties such as cationic charges, membrane fusogensity and targetability of liposomal nanocarriers for the controlled delivery of Ce6 in tumors. The self-assembled nanostructure shows the diameter ranging from 90 to 140 nm. Interestingly, Ce6 release was enhanced at pH 6.6 owing to the protonation/deprotonation of imidazole in PE-p(His)40. In addition to that it shows significant photodynamic therapeutic efficiency on KB cancer cells than free Ce6.
