- Abstract
Objective Paraquat (PQ), a widely used non-selective herbicide, induces severe lung toxicity by promoting cell death and tissue necrosis through the generation of reactive oxygen species (ROS) and free radicals. This study aimed to develop and evaluate novel niosomal nanoparticles (NPs) encapsulating curcumin and piperine to mitigate PQ-induced acute pulmonary toxicity in Balb/c mice. Methods The NPs were prepared using non-ionic surfactants and cholesterol via the thin film hydration method. Results Characterization revealed high encapsulation efficiency (>85%), proper particle sizes (264–286 nm), narrow polydispersity index (PDI) (0.19 ± 0.04 to 0.23 ± 0.02), and good stability over 90 days. Thermal analysis confirmed successful encapsulation of curcumin and piperine within the niosomal NPs. In vivo studies showed that PQ exposure significantly elevated ROS, lipid peroxidation (LPO), and protein carbonylation (PC) levels, while reducing glutathione (GSH) levels and impairing mitochondrial function (P < 0.001). However, co-treatment with curcumin- and piperine-loaded niosomal NPs effectively reversed these effects (P < 0.001), improving mitochondrial function. Conclusion The combined formulation of curcumin and piperine in niosomal NPs offers a promising therapeutic strategy for treating PQ-induced pulmonary toxicity, likely due to enhanced bioavailability and potent antioxidant activity.
