This study repurposed Prussian blue nanoparticles by doping with ytterbium (Yb) to enhance anticancer efficacy. Ytterbium-doped Prussian blue nanoparticles show promise as a new drug candidate for cancer therapy.
Area of Science:
- Nanotechnology
- Materials Science
- Drug Discovery
Background:
- Drug repurposing accelerates clinical evaluation of existing drugs.
- Prussian blue (PB) shows potential but faces limitations in nanodrug formulation and efficacy.
- Lanthanide ions offer diagnostic and therapeutic advantages for biomedical applications.
Purpose of the Study:
- To synthesize Ytterbium (Yb)-doped Prussian blue nanoparticles (NPs) for improved anticancer efficacy.
- To explore the potential of Yb-doped PB NPs as a repurposed antineoplastic drug.
- To investigate the underlying anticancer mechanisms of these novel nanoparticles.
Main Methods:
- One-step synthesis of interstitial Yb-doped PB NPs.
- Systematic comparative analysis of NP properties (morphology, size, composition, crystal structure).
- Evaluation of anticancer mechanisms involving mammalian target of rapamycin (mTOR) and adenosine monophosphate-activated protein kinase (AMPK) pathways.
Main Results:
- Yb-enriched PB NPs demonstrated improved characteristics for therapeutic applications.
- Yb-doped PB NPs were identified as a promising antineoplastic drug candidate.
- The nanoparticles were shown to disrupt cellular anabolism, catabolism, and homeostasis via mTOR and AMPK pathways.
Conclusions:
- This work successfully implements drug repurposing for Prussian blue.
- Yb-doped PB NPs represent a foundation for next-generation theranostic nanodrugs.
- The findings expand the biological applications of Yb ions in nanomedicine.
