High-density doxorubicin-conjugated polymeric nanoparticles via ring-opening metathesis polymerization

Area of Science:

• Polymer Chemistry
• Nanotechnology
• Drug Delivery

Background:

• Polymeric nanoparticles offer potential for targeted drug delivery.
• Doxorubicin is a widely used chemotherapy agent with limitations in delivery and side effects.
• Developing effective drug delivery systems is crucial for cancer therapy.

Purpose of the Study:

• To synthesize high-density doxorubicin-conjugated polymeric nanoparticles.
• To investigate the drug release profile of these nanoparticles.
• To evaluate the potential of these nanoparticles for sustained anticancer agent delivery.

Main Methods:

• Ring-opening metathesis polymerization (ROMP) was employed for nanoparticle synthesis.
• Doxorubicin was conjugated to the polymeric nanoparticles.
• In vitro drug release studies were conducted in mildly acidic aqueous solutions.

Main Results:

• High-density doxorubicin-conjugated polymeric nanoparticles were successfully prepared.
• Sustained release of approximately 50% of doxorubicin was observed over 24 hours.
• The release kinetics were studied in a mildly acidic environment.

Conclusions:

• The developed polymeric nanoparticles demonstrate a capability for sustained release of doxorubicin.
• ROMP is a viable method for creating drug-conjugated nanoparticles.
• These nanoparticles show promise as a drug delivery system for anticancer agents.
