研究目的
To synthesize and characterize glycosylated porphyrin-cored PAMAM dendrimers with specific recognition and thermosensitivity for potential applications in photodynamic therapy (PDT) and as fluorescent probes.
研究成果
The synthesized glycosylated porphyrin-cored PAMAM dendrimers exhibited high fluorescence quantum yield, singlet oxygen production efficiency, specific recognition of lectin, and remarkable temperature-responsive properties, making them promising candidates for PDT and as fluorescent probes.
研究不足
The study focuses on the synthesis and in vitro characterization of the dendrimers. Further in vivo studies are needed to evaluate their therapeutic efficacy and safety.
1：Experimental Design and Method Selection:
The study involved the synthesis of glycosylated porphyrin-cored PAMAM dendrimers via click chemistry, characterized by 1H NMR, GPC, FT-IR, UV-vis, and fluorescence analyses.
2：Sample Selection and Data Sources:
The materials included 1,3-bis(3-aminopropyl)-tetramethyldisiloxane, lactobionic acid, and other reagents purchased from commercial sources.
3：List of Experimental Equipment and Materials:
Equipment included a Varian Mercury-400 spectrometer for 1H NMR, a Spectrumlab-54 UV-visible spectrophotometer for UV-Vis spectra, and a Fluorescence Spectrophotometer (CaryEclipse, AUS) for fluorescence spectrum.
4：Experimental Procedures and Operational Workflow:
The synthesis involved the preparation of glycosylated siloxane-poly(amido amine) typed dendron and its conjugation with porphyrin via click reaction.
5：Data Analysis Methods:
The fluorescence quantum yields and singlet oxygen production efficiency were calculated using specific equations.
