Non-Viral Nanovectors Based on Cyclodextrins for siRNA Delivery: An Update to Current Technologies

Area of Science:

• Biomaterials Science
• Nanotechnology
• Pharmaceutical Sciences

Background:

• Gene delivery, particularly for small interfering RNA (siRNA), faces significant challenges in identifying effective carriers.
• Cyclodextrins (CDs), cyclic oligosaccharides, are known for enhancing drug solubility and bioavailability, and possess excellent biocompatibility.
• Their chemical versatility makes CDs ideal building blocks for supramolecular nanovectors (NVs).

Purpose of the Study:

• To provide a comprehensive overview of recent advances in designing CD-based NVs for siRNA delivery.
• To discuss the impact of structural variations and chemical functionalization on siRNA encapsulation and release.
• To highlight the potential of CD-based NVs as non-viral gene delivery agents.

Main Methods:

• Review of recent scientific literature on cyclodextrin-based nanovectors for siRNA delivery.
• Analysis of studies focusing on the design, self-assembly, and functionalization of CD-based NVs.
• Evaluation of data regarding the efficacy, transfection, and safety profiles of these nanovectors.

Main Results:

• Self-assembled nanovectors based on cyclodextrins show potential for improved siRNA delivery.
• Structural differences and chemical functionalization significantly influence the encapsulation and release properties of CD-based NVs.
• CD-based NVs are emerging as promising non-viral agents for enhanced siRNA transfection and safety.

Conclusions:

• Cyclodextrin-based nanovectors represent a versatile platform for advancing siRNA therapeutics.
• Further research into structural and chemical modifications can optimize CD-NVs for targeted gene delivery.
• These nanovectors hold significant promise for overcoming current challenges in gene administration.
