Lead structures for applications in photodynamic therapy 7. Efficient synthesis of amphiphilic glycosylated lipid porphyrin derivatives: refining linker conjugation for potential PDT applications

摘要

Herein, we report synthetic strategies towards a library of amphiphilic tetraphenyl porphyrins anchored to synthetic saccharides and lipid modalities. The carbohydrates and lipid functionalities are covalently linked to the model photosensitizer via a copper (I) catalyzed alkyne azide cycloaddition reaction or an oxypropyl linkage achieved by nucleophilic substitution chemistry. Varying substitutions of carbohydrates and lipids allows for potential fine tuning of solubility and photophysical characteristics important for imaging and treatment applications in photomedicine, specifically in photodynamic therapy.
