Biodegradable Zwitterionic Polymers as PEG Alternatives for Drug Delivery

Area of Science:

• Biomaterials Science
• Polymer Chemistry
• Drug Delivery Systems

Background:

• Poly(ethylene glycol) (PEG) is widely used in biomedicine but suffers from immunogenicity, limiting therapeutic efficacy.
• Pegylated therapeutics can elicit immune responses, restricting their clinical applications.
• There is a need for biocompatible polymers with reduced immunogenicity for advanced biomedical applications.

Purpose of the Study:

• To provide a comprehensive review of biodegradable zwitterionic polymers (ZPs) as alternatives to PEG.
• To discuss the structural designs and synthesis strategies of biodegradable ZPs.
• To highlight the applications of biodegradable ZPs in drug delivery.

Main Methods:

• Systematic review of recent scientific literature on biodegradable ZPs.
• Analysis of structural designs and synthetic approaches for integrating biodegradable polymers with zwitterions.
• Evaluation of ZP applications in delivering small molecule drugs and proteins.

Main Results:

• Biodegradable ZPs exhibit excellent water solubility and immunological inertness.
• These polymers offer favorable biomedical properties without significant long-term side effects.
• Various structural designs and synthetic methods for biodegradable ZPs have been developed.

Conclusions:

• Biodegradable ZPs represent a significant advancement over traditional PEG-based materials.
• Their tunable properties and biocompatibility make them ideal for diverse drug delivery applications.
• Further research into biodegradable ZPs promises enhanced therapeutic outcomes and reduced adverse effects.
