摘要
抗氧化剂能够延缓和/或抑制生理微环境中的氧化应激,被广泛视为一种有潜力的治疗性物质。与同类小分子抗氧化剂相比,抗氧化高分子具有更好的稳定性和更长的保留时间,因而在体内清除活性氧的能力更强。综述了含有不同抗氧化基团的常见抗氧化高分子,介绍了这些聚合物的官能团结构、活性氧清除机理、制备方法以及在生物医学领域中的应用进展,讨论了它们的优势和面对的挑战。
Antioxidants have been widely regarded as a kind of potential therapeutics thanks to their capabilities of delaying and/or inhibiting oxidative stress in the pathological micro-environment.Compared with similar small molecules,antioxidant macromolecules have better stability and longer retention time,resulting in stronger reactive oxygen species(ROS)scavenging ability in vivo.Common antioxidant macromolecules with different antioxidant groups were reviewed.The structure of functional groups,mechanism of ROS scavenging,preparation methods,and application of these polymers in biomedical fields were introduced.Their advantages and challenges were further discussed.
