CYPMPO is a free radical spin trap with excellent trapping capabilities toward hydroxyl and superoxide radicals in biological and chemical systems. Decay of the superoxide adduct of CYPMPO proceeds in an apparent first order fashion with half-lives of 15 and 51 minutes in a UV-illuminated hydrogen peroxide solution and a hypoxanthine/xanthine oxidase system, respectively. CYPMPO traps superoxide radicals generated by bovine neutrophils as effectively as DEPMPO.[1] The high melting point (126°C), low hygroscopic properties, and long shelf-life in aqueous solutions offer significant practical advantages for use of CYPMPO over DEPMPO and DMPO.

Polygalacturonic acid（Galacturonic acid polymer）为透明凝胶状聚合物，是植物细胞壁的关键组成成分。Polygalacturonic acid 被用于银纳米颗粒（AgNPs）合成，具有抗氧化与抗炎特性，可保护细胞免受 ROS 诱导的损伤并促进创伤修复。此外，以 Polygalacturonic acid 为载体的纳米颗粒还具有抗菌性能，在生物医学研究及纳米材料开发中具有多功能应用价值。
