제목 Antioxidant polymeric nanoparticles as novel therapeutics for airway inflammatory diseases.
초록 Successful pulmonary drug delivery requires polymeric drug delivery systems which have excellent biocompatibility and fast degradation rates, when frequent administration is necessary. We synthesized a new family of fully biodegradable hydroxybenzyl alcohol (HBA)-incorporated polyoxalate (HPOX) as a novel therapeutics of airway inflammatory diseases. HPOX was designed to incorporate antioxidant and anti-inflammatory HBA and peroxalate ester linkages capable of reacting with hydrogen peroxide (H2O2) in its backbone. HPOX nanoparticles exhibited highly potent antioxidant and anti-inflammatory effects by scavenging H2O2, reducing the generation of intracellular oxidative stress and suppressing the expression of pro-inflammatory mediators in stimulated macrophages. The potential of HPOX nanoparticles as an anti-asthmatic agent was evaluated using a murine model of asthma. Intratrache al administration of HPOX nanoparticles remarkably reduced the recruitment of inflammatory cells.
