Résumé
Rutin, a phenolic compound, exhibits a diverse range of biological properties, including antioxidant, anti-inflammatory, and antimicrobial effects. In this study, we aimed to investigate the potential of rutin, a naturally occurring plant bioactive molecule, to mitigate the neurotoxic effects induced by aluminum chloride (AlCl). Over a period of 6 weeks, rats were intraperitoneally injected with AlCl at a weekly dose of 60 mg/kg, while rutin treatment was administered orally via gavage at a daily dose of 30 mg/kg. AlCl exposure resulted in a significant increase lipid peroxidation (LPO) by 316.24%, nitrate levels by 504.14%, and tumor necrosis factor-alpha (TNF-α) levels by 93.82% in brain mitochondria. Additionally, AlCl exposure led to a reduction in glutathione levels and the activity of antioxidant enzymes, including superoxide dismutase (SOD) by 19.74%, glutathione peroxidase (GPx) by 44.76%, and catalase by 50.50%. There was also a significant decline in the activity of mitochondrial complex enzymes. In contrast, rutin treatment significantly enhanced the activity of antioxidant enzymes while concurrently reducing lipid peroxidation levels in rats. Specifically, rutin administration exerted a modulatory effect on the inflammatory response triggered by aluminum exposure, effectively suppressing the excessive production of nitrate and TNF-α. These findings highlight the potential of rutin as an effective therapeutic strategy in mitigating and combating neuro-inflammation and oxidative stress associated with aluminum-induced toxicity, thereby effectively restoring mitochondrial function.
