Targeted polysaccharide nanoparticle for adamplatin prodrug delivery

Area of Science:

• Biomaterials Science
• Nanotechnology
• Oncology

Background:

• Targeted drug delivery systems are crucial for improving cancer therapy efficacy.
• Hyaluronic acid receptors are overexpressed on many cancer cells, presenting a target for drug delivery.

Purpose of the Study:

• To develop and characterize self-assembled hyaluronic acid particles (HAP) for targeted anticancer drug delivery.
• To evaluate the biocompatibility, biodegradability, and in vitro/in vivo anticancer efficacy of HAP.

Main Methods:

• Self-assembly of hydrophobic anticancer drug core with a hydrophilic cyclodextrin/hyaluronic acid shell.
• Characterization using (1)H NMR titration, electron microscopy, zeta potential, and dynamic light scattering.
• In vitro and in vivo evaluation of anticancer activity and side effects.

Main Results:

• Successfully prepared nanometer-sized, biocompatible, and biodegradable HAP.
• HAP demonstrated recognition by hyaluronic acid receptors on cancer cells.
• In vitro and in vivo studies showed HAP possessed anticancer activities comparable to cisplatin with lower side effects.

Conclusions:

• Self-assembled HAP serve as an efficient targeted delivery system for anticancer drugs.
• HAP offer a promising alternative to conventional chemotherapy with improved safety profiles.
