Abstract:
Introduction: In the present study, neuroprotective effects of berberine (BBR) and berberine
nanomicelle (BBR-NM) against lipopolysaccharides (LPS)-induced stress oxidative were investigated,
and compared by evaluating their antioxidant and anti-inflammatory activities in PC12 cells,
and rat brains. A fast, green, and simple synthesis method was used to prepare BBR-NMs.
Method: The prepared BBR-NMs were then characterized using dynamic light scattering (DLS),
transmission electron microscopy (TEM), and scanning electron microscopy (SEM). In vitro experiments
were carried out on the LPS-treated PC12 cell lines to investigate the anti-cytotoxic and antioxidant
properties of BBR-NM and BBR. The results showed that BBR-NMs with a diameter of
~100 nm had higher protective effects against ROS production and cytotoxicity induced by LPS in
PC12 cells in comparison with free BBR.
Results: Moreover, in vivo experiments indicated that the activity levels of antioxidant enzymes, such as
superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx), increased in the brain
of LPS-treated rats administrated with BBR-NM at the optimum dose of 100 mg.kg-1. BBR-NM administration
also resulted in decreased concentration of lipid peroxidation (MDA) and pro-inflammatory
cytokines, such as Serum interleukin-1 beta (IL-1β) and tumor necrosis factor-alpha (TNF-α).
Conclusion: Overall, BBR-NM demonstrated higher neuroprotective effects than free BBR, making
it a promising treatment for improving many diseases caused by oxidative stress and inflammation.
