Nonionic Dendritic and Carbohydrate Based Amphiphiles: Self-Assembly and Transport Behavior

Area of Science:

• Supramolecular Chemistry
• Nanotechnology
• Materials Science

Background:

• Developing effective nanocarriers is crucial for solubilizing hydrophobic drugs.
• Biocompatible materials are preferred for drug delivery systems.

Purpose of the Study:

• To synthesize and characterize novel non-ionic dendritic and carbohydrate-based amphiphiles.
• To evaluate their supramolecular aggregate formation and drug solubilization capabilities.

Main Methods:

• Synthesis of dendritic amphiphiles with poly(glycerol) hydrophilic units and varying alkyl chain lengths.
• Characterization using cryogenic transmission electron microscopy, UV-Vis, and fluorescence spectroscopy.
• Assessment of encapsulation efficiency for hydrophobic guests like curcumin and 1-anilinonaphthalene-8-sulfonic acid (ANS).

Main Results:

• Dendritic amphiphiles 12 and 13 exhibited low critical aggregation concentrations (CAC) and hydrodynamic diameters of 8-10 nm.
• High encapsulation efficiencies for curcumin (up to 98.03%) and ANS were achieved.
• Efficient cellular uptake of encapsulated curcumin in A549 cells was observed.
• Curcumin-loaded amphiphiles demonstrated in vitro cytotoxicity against A549 cells, while the amphiphiles themselves were non-cytotoxic.

Conclusions:

• The synthesized dendritic amphiphiles are effective nanocarriers for hydrophobic drugs.
• They show promise for developing advanced drug delivery systems with enhanced solubility and targeted delivery.
• Further research can explore their therapeutic potential in various biomedical applications.
