RESUMO
The search for new therapies, derived from natural compounds in order to prevent and treat Parkinson's disease (PD) has aroused the interest of many researchers. Spondias mombin (L) has active constituents with known antioxidant and anti-inflammatory activities. The aim of this study was to evaluate the neuroprotective potential of the hexane extract of S. mombin (EHSm) in an experimental model of DP induced by rotenone in zebrafish. The analysis of GC/MS demonstrated cyclogallipharaol (13.88%) and dl-α-tocopherol (8.08%) mostly, while HPLC-DAD indicated the presence of quercetin (<5), quercetrin (6.54 mg/g) and rutin (8.83 mg/g). The zebrafish exposed for 4 weeks to rotenone (ROT, 3 µg/L) and EHSm (5, 15, 25 mg/L). EHSm (25 mg/L) was able to reverse the behavioral damage induced by ROT in the entries and time spent in the top area of the tank. The parameters biochemicals indicated of EHSm prevented oxidative stress (TBARS e total thiols), inflammation and dopamine uptake triggered by ROT, evidenced of increased on the CAT, SOD and GSH and decreased of GST, O2- production and NADPH oxidase activities. We conclude that EHSm demonstrate a neuroprotector effect mediated through anxiolytic and antioxidant activities. However, more studies are necessary to elucidate the exact mechanism underlying the effects of EHSm on DP induced by rotenone in zebrafish.
