Butylglyceryl Pectin Nanoparticles: Synthesis, Formulation and Characterization.

Area of Science:

• Materials Science
• Polymer Chemistry
• Nanotechnology

Background:

• Pectin, a polysaccharide known for gel-forming properties, has traditional applications in food and pharmaceuticals.
• Chemical modification of pectin can reduce hydrophilicity, enabling the development of novel drug delivery systems.
• Butylglyceryl pectins (P-OX4) were synthesized to explore their potential as drug carriers.

Purpose of the Study:

• To synthesize and characterize butylglyceryl pectins (P-OX4) for potential use as drug carriers.
• To formulate these modified pectins into nanoparticles.
• To evaluate the physicochemical properties and drug loading capacity of the resulting nanoformulations.

Main Methods:

• Synthesis of butylglyceryl pectins (P-OX4) using n-butylglycidyl ether.
• Characterization using chromatography, spectroscopy (NMR, FT-IR), and thermal analysis.
• Nanoparticle formulation via nanoprecipitation and characterization of size, morphology, zeta potential, and drug loading.

Main Results:

• Confirmed a modification degree of 10.4-13.6% in butylglyceryl pectins.
• Observed increased thermal stability and molecular weight, with decreased viscosity compared to original pectin.
• Resulting nanoparticles were spherical (<300 nm) with good stability (zeta potential -20 to -26 mV) and 10% Doxorubicin loading.

Conclusions:

• Butylglyceryl pectin nanoparticles were successfully synthesized and characterized.
• The modified pectin nanoparticles exhibit favorable physicochemical properties for drug delivery.
• Further investigation into their drug delivery potential is warranted.
