Nanoconjugated quercetin enhances anticancer potential by overcoming poor solubility and bioavailability limitations. This review explores various nanocarrier systems for improved quercetin delivery in cancer chemoprevention.
Area of Science:
- Pharmacology and Nanotechnology
- Cancer Therapeutics
- Bioavailability Enhancement
Background:
- Metastatic cancer spread is a leading global cause of mortality.
- Quercetin, a natural bioflavonoid, exhibits documented cancer-preventive activities including anti-inflammatory, anti-proliferative, and anti-angiogenic effects.
- Clinical application of quercetin is hindered by poor water solubility, chemical instability, short half-life, and low bioavailability.
Purpose of the Study:
- To review various nanoconjugated quercetin delivery systems for improved cancer chemoprevention.
- To explore the potential of nanoconjugated quercetin as a promising onco-therapeutic agent.
- To highlight the importance of controlled drug delivery systems for overcoming quercetin's limitations.
Main Methods:
- Review of literature on nanoconjugated quercetin delivery systems.
- Analysis of various nanocarriers including liposomes, silver nanoparticles, PLGA, and polymeric micelles.
- Evaluation of in vitro and in vivo tumor models utilizing nanoconjugated quercetin.
Main Results:
- Nanoconjugated quercetin demonstrates controlled drug release and prolonged retention in tumors.
- Enhanced anticancer potential is observed with nanoconjugated quercetin compared to free quercetin.
- Diverse nanocarrier systems show promise for delivering quercetin effectively.
Conclusions:
- Nanoconjugated quercetin offers a promising strategy to overcome the limitations of conventional quercetin therapy.
- Various nanocarrier platforms, including liposomes and polymeric micelles, are effective for quercetin delivery.
- Further research and validation of nanoconjugated quercetin hold significant potential for cancer treatment.
