Whey protein isolate nanoparticles were developed to improve curcumin
Area of Science:
- Biomaterials Science
- Nanotechnology
- Drug Delivery
Background:
- Curcumin (CUR) is a potent anticancer agent with poor aqueous solubility, limiting its clinical use.
- Developing effective delivery systems is crucial for enhancing CUR's therapeutic potential.
Purpose of the Study:
- To develop enzyme-responsive whey protein isolate (WPI) nanoparticles for targeted curcumin delivery.
- To overcome curcumin's poor solubility and achieve controlled release.
Main Methods:
- Curcumin was formulated into a solid dispersion with WPI using freeze-drying, significantly enhancing solubility.
- Nanoparticles were generated from the CUR-WPI solid dispersion via thermal gelation, avoiding organic solvents.
- Characterization included Differential Scanning Calorimetry (DSC) and Fourier-transform infrared (FT-IR) spectroscopy.
Main Results:
- The developed nanoparticles showed a high drug loading efficiency of 85%.
- Minimal CUR release occurred in physiological buffer (pH 7.4) over 24 hours.
- Trypsin exposure triggered rapid nanoparticle degradation, releasing 95% of CUR within 3 hours.
Conclusions:
- WPI-based nanoparticles from solid dispersions offer a promising platform for solubility enhancement of hydrophobic drugs.
- These nanoparticles enable biocompatible and protease-triggered delivery of anticancer agents.
- This approach holds potential for targeted drug delivery in cancer therapy.
