• To assess the potential of these lipid nanoparticles in biological applications like gene delivery and immunization.

Main Methods:

• Synthesis of 12 novel lipid compounds utilizing two distinct schemes based on cyanuric chloride.
• Characterization of synthesized lipids.
• Dynamic light scattering to assess nanoparticle stability.
• In vitro testing for toxicity, drug/gene/peptide encapsulation, plasmid delivery, and immunogenicity.

Main Results:

• Eight out of twelve synthesized lipids successfully formed stable nanoparticles for over one month.
• The developed lipids demonstrated capability for plasmid delivery in vitro.
• The lipids induced antibody profiles comparable to existing hydrophobic anchors in liposomal peptide vaccines.
• Encapsulation of carboxyfluorescein was not observed, but plasmid delivery was successful.

Conclusions:

• A facile strategy using cyanuric chloride enables the rapid development of diverse synthetic lipids.
• These novel lipids can form stable nanoparticles suitable for biological applications.
• The synthesized lipids show potential as effective agents for gene delivery and in the development of liposomal vaccines.
