Cyclodextrin-Based Polymeric Drug Delivery Systems for Cancer Therapy.

Area of Science:

• Biomaterials Science
• Polymer Chemistry
• Nanotechnology

Background:

• Cyclodextrins (CDs) are cyclic oligosaccharides with beneficial properties like low toxicity and biocompatibility.
• However, CDs face challenges in drug delivery, including poor pharmacokinetics and lack of target specificity.
• Combining CDs with polymers offers a promising strategy to overcome these limitations for cancer treatment.

Purpose of the Study:

• To review and classify four types of cyclodextrin-based polymeric carriers for cancer therapy.
• To highlight the structural properties and applications of these advanced drug delivery systems.
• To discuss the potential of CD-based polymers in delivering chemotherapeutics and gene agents.

Main Methods:

• Literature review and classification of CD-based polymeric carriers.
• Analysis of structural properties, including amphiphilicity and nanoassembly formation.
• Examination of drug loading strategies (inclusion, encapsulation, conjugation) and functionalization for targeting and stimuli-responsive release.

Main Results:

• Four main types of CD-based polymeric carriers were identified and classified.
• Most carriers exhibit amphiphilic properties, enabling the formation of nanoassemblies.
• Anticancer drugs can be incorporated via inclusion, encapsulation, or conjugation.
• Functionalization with targeting agents and stimuli-responsive materials is feasible.

Conclusions:

• CD-based polymers represent an attractive platform for developing superior drug delivery systems for cancer therapy.
• These carriers offer improved pharmacokinetics, target specificity, and controlled release of anticancer agents.
• The combination of CDs and polymers provides a versatile approach for advanced cancer treatment strategies.
