We attempted to increase the effectiveness of SME by encapsulating them in chitosan. Neuroprotective potency of SME and SME-loaded chitosan nanoparticles (SME-CNPs) were shown in SH-SY5Y cell line against H2O2-induced oxidative stress. Methods: We produced CNPs and SME-CNPs by ionic gelation method and properly determined their physical characteristics. Encapsulation efficiency, loading capacity, and in vitro release tests were performed for SME-CNPs. The neurotoxicity and neuroprotective efficiency in SH-SY5Y cell line against H2O2 was also investigated. Results: The size of SME-CNPs was 168.2 ± 11.12 nm with zeta potential 10.6 ± 1.0 mV. The encapsulation efficiency and loading capacity were successfully achieved at 96.6% and 1.89% respectively. SME and SME-CNPs improved cell viability higher than 80%, and SME-CNPs exhibited significant neuroprotective effects against H2O2 damage. Conclusions: It was concluded that SME and SME-CNPs highly prevent damage caused by H2O2 and reduce cell damage in vitro by their neuroprotective effects.
